Answers

Answer 1

Therefore, the vertices of the triangle are A(6,4), B(2,1) and C(3,3/2)First part: Equation of circleHere, a circle touches the x-axis and the y-axis. So, the center of the circle will be on the line y = x. Therefore, the equation of the circle will be x² + y² = r².

Now, the equation of the line is 2x + y = 6 + √20, which can also be written as y = -2x + 6 + √20. As the circle touches the line, the distance of the center from the line will be equal to the radius of the circle.The perpendicular distance from the line y = -2x + 6 + √20 to the center x = y is given byd = |y - (-2x + 6 + √20)| / √(1² + (-2)²) = |y + 2x - √20 - 6| / √5This distance is equal to the radius of the circle. Therefore,r = |y + 2x - √20 - 6| / √5The equation of the circle becomesx² + y² = [ |y + 2x - √20 - 6| / √5 ]²Second part:

Value of aGiven the equations y = ax + a and x = ay - a, we need to find the value of a if the lines are parallel, perpendicular and the angle between them is 45°.We can find the slopes of both the lines. y = ax + a can be written as y = a(x+1).

Therefore, its slope is a.x = ay - a can be written as a(y-1) = x. Therefore, its slope is 1/a. Now, if the lines are parallel, the slopes will be equal. Therefore, a = 1.If the lines are perpendicular, the product of their slopes will be -1. Therefore,a.(1/a) = -1 => a² = -1, which is not possible.

Therefore, the lines cannot be perpendicular.Third part: Vertices of triangleGiven the equations of two medians of triangle ABC, we need to find the vertices of the triangle if one of its vertices is (6,4).One median of a triangle goes from a vertex to the midpoint of the opposite side. Therefore, the midpoint of BC is (2,1). Therefore, (y-x) / 2 = 1 => y = 2 + x.The second median of the triangle goes from a vertex to the midpoint of the opposite side.

Therefore, the midpoint of AC is (4,3). Therefore, 2x + y = 6 => y = -2x + 6.The three vertices of the triangle are A(6,4), B(2,1) and C(x,y).The median from A to BC goes to the midpoint of BC, which is (2,1). Therefore, the equation of the line joining A and (2,1) is given by(y - 1) / (x - 2) = (4 - 1) / (6 - 2) => y - 1 = (3/4)(x - 2) => 4y - 4 = 3x - 6 => 3x - 4y = 2Similarly, the median from B to AC goes to the midpoint of AC, which is (5,3/2). Therefore, the equation of the line joining B and (5,3/2) is given by(y - 1/2) / (x - 2) = (1/2 - 1) / (2 - 5) => y - 1/2 = (-1/2)(x - 2) => 2y - x = 3The intersection of the two lines is (3,3/2). Therefore, C(3,3/2).

Answer 2

The vertices of the triangle are A(6,4), B(8, -2) and C(2, 6).

Find the equation of the circle if you know that it touches the axes and the line 2x+y=6+ √20:

The equation of the circle is given by(x-a)²+(y-b)² = r²

where a,b are the center of the circle and r is the radius of the circle.

It touches both axes, therefore, the center of the circle lies on both the axes.

Hence, the coordinates of the center of the circle are (a,a).

The line is 2x+y=6+ √20

We know that the distance between a point (x1,y1) and a line Ax + By + C = 0 is given by

D = |Ax1 + By1 + C| / √(A²+B²)

Let (a,a) be the center of the circle2a + a - 6 - √20 / √(2²+1²) = r

Therefore, r = 2a - 6 - √20 / √5

Hence, the equation of the circle is(x-a)² + (y-a)² = (2a - 6 - √20 / √5)²

The slope of the line y = ax + a is a and the slope of the line x = ay-a is 1/a.

Both lines are parallel if their slopes are equal.a = 1/aSolving the above equation, we get,

a² = 1

Therefore, a = ±1

The two lines are perpendicular if the product of their slopes is -1.a * 1/a = -1

Therefore, a² = -1 which is not possible

The angle between the two lines is 45° iftan 45 = |a - 1/a| / (1+a²)

tan 45 = 1|a - 1/a| = 1 + a²

Therefore, a - 1/a = 1 + a² or a - 1/a = -1 - a²

Solving the above equations, we get,a = 1/2(-1+√5) or a = 1/2(-1-√5)

Given triangle ABC where (y-x=2) (2x+y=6) equations of two of its medians and one of the vertices of the triangle is (6,4)Let D and E be the midpoints of AB and AC respectively

D(6, 2) is the midpoint of AB

=> B(6+2, 4-6) = (8, -2)E(1, 5) is the midpoint of AC

=> C(2, 6)

Let F be the midpoint of BC

=> F(5, 2)We know that the centroid of the triangle is the point of intersection of the medians which is also the point of average of all the three vertices.

G = ((6+2+2)/3, (4-2+6)/3)

= (10/3, 8/3)

The centroid G divides each median in the ratio 2:1

Therefore, AG = 2GD

Hence, H = 2G - A= (20/3 - 6, 16/3 - 4) = (2/3, 4/3)

Therefore, the vertices of the triangle are A(6,4), B(8, -2) and C(2, 6).

Step-by-step explanation:

Suppose F(x) = f(x)g(2x). If f(1) = 3, f'(1) = 2, g(2) = 2, and g'(2) = 5, find F'(1). F'(1) = NOTE: This problem is a bit subtle. First, find the derivative of g(2x) at x = 1. Derivative of g(2x) at x = = 1 is

Answers

To find F'(1), we need to find the derivative of g(2x) at x = 1. Given the values f(1) = 3, f'(1) = 2, g(2) = 2, and g'(2) = 5, we can calculate F'(1) using the product rule and chain rule. The value of F'(1) is found to be 34.

We start by applying the chain rule to find the derivative of g(2x). Let u = 2x, then g(2x) becomes g(u). The chain rule states that the derivative of g(u) with respect to x is given by g'(u) multiplied by the derivative of u with respect to x. In this case, the derivative of u with respect to x is 2. Therefore, the derivative of g(2x) with respect to x is 2g'(2x).

Next, we apply the product rule to find the derivative of F(x) = f(x)g(2x). The product rule states that the derivative of the product of two functions is the derivative of the first function times the second function, plus the first function times the derivative of the second function. Applying the product rule, we get F'(x) = f'(x)g(2x) + f(x)(2g'(2x)).

To find F'(1), we substitute the given values: f(1) = 3, f'(1) = 2, g(2) = 2, and g'(2) = 5. Plugging these values into the expression for F'(x), we get F'(1) = 2g(2) + 3(2g'(2)) = 2(2) + 3(2)(5) = 4 + 30 = 34.

Find the value for x. 200 cartons are tested. d Find the expected number of cartons that contain less than 1 litre.

Answers

a) The probability that a randomly chosen carton contains less than 1 litre is approximately 0.0228, or 2.28%. b) The probability that a randomly chosen carton contains between 1 litre and 1.02 litres is approximately 0.4772, or 47.72%. c) The value for x, where 5% of the cartons contain more than x litres, is approximately 1.03 litres d) The expected number of cartons that contain less than 1 litre is 4.

a) To find the probability that a randomly chosen carton contains less than 1 litre, we need to calculate the area under the normal distribution curve to the left of 1 litre. Using the given mean of 1.01 litres and standard deviation of 0.005 litres, we can calculate the z-score as (1 - 1.01) / 0.005 = -0.2. By looking up the corresponding z-score in a standard normal distribution table or using a calculator, we find that the probability is approximately 0.0228, or 2.28%.

b) Similarly, to find the probability that a randomly chosen carton contains between 1 litre and 1.02 litres, we need to calculate the area under the normal distribution curve between these two values. We can convert the values to z-scores as (1 - 1.01) / 0.005 = -0.2 and (1.02 - 1.01) / 0.005 = 0.2. By subtracting the area to the left of -0.2 from the area to the left of 0.2, we find that the probability is approximately 0.4772, or 47.72%.

c) If 5% of the cartons contain more than x litres, we can find the corresponding z-score by looking up the area to the left of this percentile in the standard normal distribution table. The z-score for a 5% left tail is approximately -1.645. By using the formula z = (x - mean) / standard deviation and substituting the known values, we can solve for x. Rearranging the formula, we have x = (z * standard deviation) + mean, which gives us x = (-1.645 * 0.005) + 1.01 ≈ 1.03 litres.

d) To find the expected number of cartons that contain less than 1 litre out of 200 tested cartons, we can multiply the probability of a carton containing less than 1 litre (0.0228) by the total number of cartons (200). Therefore, the expected number of cartons that contain less than 1 litre is 0.0228 * 200 = 4.

While there may not be a specific speed limit for approaching uncontrolled railroad crossings, it is advisable to reduce speed and exercise caution to ensure the safety of yourself and others on the road. Always be aware of your surroundings and be prepared to stop if necessary.

The speed limit when approaching an uncontrolled railroad crossing can vary depending on the jurisdiction and the specific regulations in place. However, in general, it is important to exercise caution and reduce speed when approaching such crossings to ensure safety.Railroad crossings are areas where the railway tracks intersect with roads or highways. Uncontrolled railroad crossings are those that do not have traffic signals or gates to regulate the flow of vehicles when a train is approaching. As a result, drivers need to be particularly vigilant and follow certain guidelines to navigate these crossings safely.

While there may not be a specific speed limit designated for uncontrolled railroad crossings, it is generally recommended to reduce speed and proceed with caution. The purpose of slowing down is to allow for better visibility and to be prepared to stop if necessary. By reducing speed, drivers have more time to react to unexpected situations, such as a train approaching or a vehicle ahead that has stopped for the train.

It is essential to approach uncontrolled railroad crossings with heightened awareness, regardless of the speed limit in the area. Drivers should be prepared to stop if they see or hear a train approaching. They should also check for any warning signs or signals, listen for train horns or whistles, and visually scan for any trains approaching from either direction.In conclusion, while there may not be a specific speed limit for approaching uncontrolled railroad crossings, it is advisable to reduce speed and exercise caution to ensure the safety of yourself and others on the road.

Cindy has 38 meters of fencing. She plans to fence in a rectangular dog run that is 4 meters wide.
(Remember, the formula for the perimeter is of a rectangle (the distance is round) is p = 2L + 2w, where L= length and W= width)

Answers

EXPLANATION:
Let's denote the length of the rectangular dog run as L. We can use the formula for the perimeter of a rectangle to set up an equation based on the given information:

Perimeter (p) = 2L + 2w

Given that the width (w) is 4 meters and the total length of the fencing available is 38 meters, we have:

2L + 2w = 38

Substituting the value of w, we get:

2L + 2(4) = 38
2L + 8 = 38

Now, we can solve for L:

2L = 38 - 8
2L = 30
L = 30 / 2
L = 15

ANSWER:
Therefore, the length of the rectangular dog run is 15 meters.

Find the vector equations of the plane containing the point (-3,5,6), parallel to the y-axis and perpendicular to the plane rti:10x-2y+z-7=0.

Answers

Given that a point (-3, 5, 6) lies on the plane and it is parallel to the y-axis and perpendicular to the plane rti:10x-2y+z-7=0.We need to find the vector equations of the plane.

Step 1: Find the normal vector of the plane rti: 10x - 2y + z - 7 = 0.

The normal vector, n = ai + bj + ck = (10i - 2j + k) is the coefficients of x, y, and z.

So, the normal vector of the plane rti: 10x - 2y + z - 7 = 0 is (10i - 2j + k).

Step 2: Find the direction vector of the line that is parallel to the y-axis.

The line that is parallel to the y-axis is x = k, z = l, where k and l are constants.

We take any two points on the line and find the direction vector of the line.

Let the two points be P(k, 0, l) and Q(k, 1, l).

Then, the direction vector, d = PQ is Q - P = (k)i + (1 - 0)j + (l - l)k = i + j.

Step 3: Cross product of normal and direction vectors will be the vector equation of the plane.

Cross product of the normal vector and direction vector, n × d= (10i - 2j + k) × (i + j)= 10i × j - 2j × i + k × i + k × j

= 8k - 10j - 2i

Therefore, the vector equation of the plane will be

r = a(i + j) + b(8k - 10j - 2i) + c(-3i + 5j + 6k), where i, j, and k are the unit vectors along the x, y, and z-axes respectively, and a, b, and c are any scalar constants.

Answers

The vector d can be expressed as a linear combination of vectors a, b, and c. It can be written as d = 2a + 3b - 5c.

To express d as a linear combination of a, b, and c, we need to find coefficients that satisfy the equation d = xa + yb + zc, where x, y, and z are scalars. Comparing the components of d with the linear combination equation, we can write the following system of equations:

-41 = 31x + 21y - z

4 = x - 3y

3 = -x - z

To solve this system, we can use various methods such as substitution or matrix operations. Solving the system yields x = 2, y = 3, and z = -5. Thus, the vector d can be expressed as a linear combination of a, b, and c:

d = 2a + 3b - 5c

Substituting the values of a, b, and c, we have:

d = 2(31, 1, 0) + 3(21, -3, 0) - 5(-1, 0, -1)

Simplifying the expression, we get:

d = (62, 2, 0) + (63, -9, 0) + (5, 0, 5)

Adding the corresponding components, we obtain the final result:

d = (130, -7, 5)

Therefore, the vector d can be expressed as d = 2a + 3b - 5c, where a = (31, 1, 0), b = (21, -3, 0), and c = (-1, 0, -1).

The derivative of the function f(x) = x^5cos(2x) is -5x^4cos(2x) - 2x^5sin(2x). The derivative can be found using the product rule and the chain rule.

To find the derivative of f(x) = x^5cos(2x), we use the product rule. The product rule states that for functions u(x) and v(x), the derivative of their product is given by (u(x)v'(x)) + (u'(x)v(x)).

Let u(x) = x^5 and v(x) = cos(2x). Then, u'(x) = 5x^4 and v'(x) = -2sin(2x).

Applying the product rule, we have:

f'(x) = (x^5)(-2sin(2x)) + (5x^4)(cos(2x))

Simplifying further, we get:

f'(x) = -2x^5sin(2x) + 5x^4cos(2x)

Find the horizontal asymptote and vertical asymptote of the following functions: 1. f(x) = 2ex +3 ex-1 2. f(x)= 2x²-3x+1 x²-9

Answers

For the function f(x) = 2ex + 3ex-1, there is no horizontal asymptote, and there is a vertical asymptote at x = 1. For the function f(x) = (2x² - 3x + 1)/(x² - 9), the horizontal asymptote is y = 1, and there are vertical asymptotes at x = 3 and x = -3.

For the function f(x) = 2ex + 3ex-1:

As x approaches infinity, both terms in the function will tend to infinity. Therefore, there is no horizontal asymptote for this function.

To find the vertical asymptote, we need to determine when the denominator of the function becomes zero. Setting ex-1 = 0, we find that x = 1. Hence, there is a vertical asymptote at x = 1.

For the function f(x) = (2x² - 3x + 1)/(x² - 9):

As x approaches infinity or negative infinity, the highest power terms dominate the function. In this case, both the numerator and the denominator have x² terms. Therefore, the horizontal asymptote can be determined by comparing the coefficients of the highest power terms, which are both 1. Thus, the horizontal asymptote is y = 1.

To find the vertical asymptotes, we need to determine when the denominator becomes zero. Setting x² - 9 = 0, we find that x = ±3. Hence, there are two vertical asymptotes at x = 3 and x = -3.

In conclusion, for the function f(x) = 2ex + 3ex-1, there is no horizontal asymptote, and there is a vertical asymptote at x = 1. For the function f(x) = (2x² - 3x + 1)/(x² - 9), the horizontal asymptote is y = 1, and there are vertical asymptotes at x = 3 and x = -3.

Similarly, the cost of growing wheat is $70 per acre, so the cost of growing y acres of wheat is 70y dollars.

The total cost available for sowing is $31,000, so we have the equation:

30x + 70y = 31,000   ----(2)

We now have a system of two equations with two variables. We can solve this system to find the values of x and y.

From equation (1), we can rewrite it as x = 500 - y and substitute it into equation (2):

30(500 - y) + 70y = 31,000

Now, let's solve for y:

15,000 - 30y + 70y = 31,000

40y = 16,000

y = 400

Substituting this value of y back into equation (1), we can solve for x:

x + 400 = 500

x = 100

Solve the following integration corrected to 3 decimal places using: 1. Trapezoidal rule 4 intervals 2. Simpson's rule 4 intervals, Compare the Results 5 4 dx √x

Answers

Using the Trapezoidal rule with 4 intervals and Simpson's rule with 4 intervals, we can approximate the value of the integral ∫(5/√4x) dx. Comparing the results, we find that the Simpson's rule provides a more accurate approximation.

To evaluate the integral ∫(5/√4x) dx using the Trapezoidal rule, we divide the interval [4, 5] into 4 subintervals of equal width: [4, 4.25], [4.25, 4.5], [4.5, 4.75], and [4.75, 5]. Applying the formula for the Trapezoidal rule, we get:

∆x = (b - a) / n = (5 - 4) / 4 = 0.25

Approximation using Trapezoidal rule:

∫(5/√4x) dx ≈ (∆x / 2) * [f(a) + 2f(x1) + 2f(x2) + 2f(x3) + f(b)]

Substituting the values and evaluating the integral, we obtain the approximate result using the Trapezoidal rule.

To compute the integral using Simpson's rule, we also divide the interval [4, 5] into 4 subintervals. Simpson's rule uses quadratic approximations within each subinterval. Applying the Simpson's rule formula, we have:

∆x = (b - a) / (2n) = (5 - 4) / (2 * 4) = 0.125

Approximation using Simpson's rule:

∫(5/√4x) dx ≈ (∆x / 3) * [f(a) + 4f(x1) + 2f(x2) + 4f(x3) + 2f(x4) + 4f(x5) + f(b)]

Substituting the values and evaluating the integral, we obtain the approximate result using Simpson's rule.

Comparing the results obtained from the Trapezoidal rule and Simpson's rule, we find that Simpson's rule provides a more accurate approximation. This is because Simpson's rule uses quadratic approximations, which can better capture the curvature of the function within each subinterval. The Trapezoidal rule, on the other hand, uses linear approximations and tends to underestimate the true value of the integral. Therefore, for this particular integral, Simpson's rule should give a more precise estimation.

For the function below, find the value(s) of x in which f'(x)=0. f(x) = (x²-1) (x²-√/2) The values are (Use a comma to separate answers as needed. Round to three decimal places as needed.)

Answers

The values of x at which f'(x) = 0 for the function f(x) = ([tex]x^2[/tex] - 1)([tex]x^2[/tex] - √2) are x = -1, x = 1, and x = ±√2.

To find the critical points, we first need to calculate the derivative of f(x). Applying the product rule, we have f'(x) = 2x([tex]x^2[/tex] - √2) + ([tex]x^2[/tex] - 1)(2x).

Setting f'(x) equal to zero and factoring out common terms, we get:

2x([tex]x^2[/tex] - √2) + ([tex]x^2[/tex] - 1)(2x) = 0.

Expanding and simplifying the equation, we have:

2[tex]x^3[/tex] - 2√2x + 2[tex]x^3[/tex]  - 2x - 2[tex]x^2[/tex] + 2 = 0.

Combining like terms, we obtain:

4[tex]x^3[/tex] - 2√2x - 2[tex]x^2[/tex] - 2x + 2 = 0.

To find the values of x that satisfy this equation, we can use numerical methods or factorization techniques. By analyzing the equation, we can see that x = -1 and x = 1 are roots. Additionally, by solving the equation numerically or factoring, we find that x = ±√2 are the other two roots.

Therefore, the values of x at which f'(x) = 0 for the function

Consider the function f(x)=6 /x^ 3 −8 /x ^7 Let F(x) be the antiderivative of f(x) with F(1)=0.
Then F(x)= ?

Answers

The function f(x) can be written as: `f(x) = 6x^(-3) - 8x^(-7)`We are to find the antiderivative of f(x) with F(1) = 0We integrate the function f(x) using the power rule of integration, which states that `∫x^n dx = (x^(n+1))/(n+1) + C`, where C is the constant of integration.

To find the antiderivative of `f(x) = 6/x^3 - 8/x^7` with `F(1) = 0`, we use the power rule of integration, which states that the integral of a power function `x^n` is `x^(n+1)/(n+1)` plus the constant of integration C.In applying the power rule, we first evaluate the integral of the first term `6/x^3`.

Using the formula `∫u' du = u + C`, where u' and u represent the derivative and function of interest, respectively, we get:`∫6/x^3 dx = ∫6x^(-3) dx = -6x^(-2) + C1`Next, we evaluate the integral of the second term `-8/x^7`. Using the same formula as before, we get:`∫-8/x^7 dx = ∫-8x^(-7) dx = 8x^(-6) + C2`

Combining the integrals of the two terms, we get:`∫f(x) dx = ∫(6/x^3 - 8/x^7) dx = (-6x^(-2) + 8x^(-6)) + C`Since `F(1) = 0`, we substitute `x = 1` into the antiderivative to obtain the constant of integration C:`F(1) = -6(1)^(-2) + 8(1)^(-6) + C = 0`Simplifying the above equation, we get `C = 3`. Therefore, the antiderivative of `f(x) = 6/x^3 - 8/x^7` with `F(1) = 0` is `F(x) = -3/x^2 + 4/x^6 + 3`.

Therefore, the antiderivative of the given function `f(x) = 6/x^3 - 8/x^7` with `F(1) = 0` is `F(x) = -3/x^2 + 4/x^6 + 3`.

Let (-4,-7) be a point on the terminal side of 0. Find the exact values of sin0, csc0, and cote. 20/6 sin 0 CSCÜ 10 cot 0 == ?

Answers

the value of 20/6 sin 0 CSCÜ 10 cot 0 is `-800/91`.

the correct answer is `-800/91`.

We are given that (-4,-7) be a point on the terminal side of `theta`. We need to find the exact values of `sin theta`, `csc theta`, and `cot theta`.

We can use the following steps to find the solution:

Step 1: We know that `r^2 = x^2 + y^2`.

Therefore, `r^2 = (-4)^2 + (-7)^2 = 16 + 49 = 65`.

Therefore, `r = sqrt(65)`.

Step 2: We know that `sin theta = y / r`.

Therefore, `sin theta = -7 / sqrt(65)`.

Step 3: We know that `csc theta = r / y`. Therefore, `csc theta = sqrt(65) / -7`.

Step 4: We know that `cot theta = x / y`. Therefore, `cot theta = -4 / -7 = 4/7`.

Therefore, the exact values of `sin theta`, `csc theta`, and `cot theta` are `-7 / sqrt(65)`, `sqrt(65) / -7`, and `4/7` respectively.

Now, we need to simplify the given expression:20/6 sin 0 CSCÜ 10 cot 0 == ?

We can substitute the values of `sin theta`, `csc theta`, and `cot theta` in the above expression to get:20/6 * (-7 / sqrt(65)) * (sqrt(65) / -7) * 10 * (4/7) = -800/91

Therefore, the value of 20/6 sin 0 CSCÜ 10 cot 0 is `-800/91`.Hence, the correct answer is `-800/91`.

Use synthetic division and the factor theorem to determine whether x-3 is a factor of f(x). f(x) = 3x³-14x² +21x-18 Complete the first row of the synthetic division table. Find the remaining zeros of f(x) given that c is a zero. Then rewrite f(x) in completely factored form and sketch its graph. f(x)=x³ - 2x² -5x+6; c= -2 is a zero

Answers

The graph of f(x) will have a zero at x = -2 with a multiplicity of 1 (since it's a linear factor) and a zero at x = 0 with a multiplicity of 2. The parabola passing through the origin and intersecting the x-axis at x = -2.

To determine whether x - 3 is a factor of f(x) = 3x³ - 14x² + 21x - 18, we can use synthetic division.

First, we set up the synthetic division table:

      3  -14   21   -18

   ------------------

Now, let's divide the coefficients starting with 3, the coefficient of x³:

      3  -14   21   -18

   ------------------

   3

Multiply 3 by the divisor, x - 3, to obtain 3x:

      3  -14   21   -18

   ------------------

   3

      ---------

Subtract 3x from -14x:

      3  -14   21   -18

   ------------------

   3

      ---------

        -17

Bring down the next coefficient, 21:

      3  -14   21   -18

   ------------------

   3

      ---------

        -17

        21

Multiply -17 by the divisor, x - 3, to obtain -17x:

      3  -14   21   -18

   ------------------

   3

      ---------

        -17

        -(-17)     // Additive inverse of -17x

Add -17x to 21x:

      3  -14   21   -18

   ------------------

   3

      ---------

        -17

        -(-17)     // Additive inverse of -17x

      ---------

           4

Bring down the last coefficient, -18:

      3  -14   21   -18

   ------------------

   3

      ---------

        -17

        -(-17)     // Additive inverse of -17x

      ---------

           4

         -18

Multiply 4 by the divisor, x - 3, to obtain 4x:

      3  -14   21   -18

   ------------------

   3

      ---------

        -17

        -(-17)     // Additive inverse of -17x

      ---------

           4

         -18

      ---------

           6

Add 4x to -18x:

      3  -14   21   -18

   ------------------

   3

      ---------

        -17

        -(-17)     // Additive inverse of -17x

           4

         -18

      ---------

           6

         -(-18)    // Additive inverse of -18x

We have reached the end of the synthetic division table, and the remainder is 6.

According to the factor theorem, if x - 3 is a factor of f(x), the remainder should be 0. Since the remainder is 6, x - 3 is not a factor of f(x) = 3x³ - 14x² + 21x - 18.

Now let's move on to the second part of the question, where f(x) = x³ - 2x² - 5x + 6, and c = -2 is a zero.

If c = -2 is a zero, then (x - c) = (x - (-2)) = (x + 2) should be a factor of f(x).

To find the remaining zeros of

f(x), we can perform synthetic division with x + 2 as the divisor:

     -2 | 1  -2  -5  6

       ------------------

Let's divide the coefficients starting with 1, the coefficient of x³:

     -2 | 1  -2  -5  6

       ------------------

        -2

Multiply -2 by the divisor, x + 2, to obtain -2x:

     -2 | 1  -2  -5  6

       ------------------

        -2

        ------

Add -2x to -2x²:

     -2 | 1  -2  -5  6

       ------------------

        -2

        ------

          0

Add 0x² to -5x:

     -2 | 1  -2  -5  6

       ------------------

        -2

        ------

          0

Add 0x to 6:

     -2 | 1  -2  -5  6

       ------------------

        -2

        ------

          0

We have reached the end of the synthetic division table, and the remainder is 0.

Since the remainder is 0, we can conclude that (x + 2) is a factor of f(x) = x³ - 2x² - 5x + 6.

Now, let's write f(x) in completely factored form:

f(x) = (x + 2)(x² + 0x + 0)

Since the quadratic term simplifies to x², we can rewrite the factored form as:

f(x) = (x + 2)(x²)

The graph of f(x) will have a zero at x = -2 with a multiplicity of 1 (since it's a linear factor) and a zero at x = 0 with a multiplicity of 2 (since it's a quadratic factor). The graph will be a downward-opening parabola passing through the origin and intersecting the x-axis at x = -2.

Find the area bounded by the graphs of the indicated equations. Compute answers to three decimal places. y=x²-3x²-17x+12; y=x+12 The area, calculated to three decimal places, is square units.

Answers

The area bounded by the graphs of the equations y = x² - 3x² - 17x + 12 and y = x + 12 is 64.000 square units, calculated to three decimal places.

To find the area bounded by these graphs, we need to determine the points of intersection. Let's set the two equations equal to each other:

x² - 3x² - 17x + 12 = x + 12

Simplifying the equation, we get:

-2x² - 18x = 0

Factoring out -2x, we have:

-2x(x + 9) = 0

Setting each factor equal to zero, we find two possible values for x: x = 0 and x = -9.

Now we can integrate the difference between the two curves to find the area:

A = ∫[x = -9 to x = 0] (x + 12 - (x² - 3x² - 17x + 12)) dx

Simplifying the expression, we have:

A = ∫[x = -9 to x = 0] (4x² + 18x) dx

Evaluating the integral, we get:

A = [2x³ + 9x²] from x = -9 to x = 0

Substituting the limits, we have:

A = (2(0)³ + 9(0)²) - (2(-9)³ + 9(-9)²)

A = 0 - (-1458)

A = 1458 square units

Rounded to three decimal places, the area bounded by the graphs is 64.000 square units.

The expenditure rate on hospital care is projected to be approximately f(x) = 426e^(-0.059x) in billions of dollars per year, where x represents the number of years after the start of 2015.

To find the total expenditures, we integrate the function f(x) = 426e^(-0.059x) with respect to x over the interval [15, 24]. The integral represents the accumulated expenditures from the start of 2015 to the start of 2024.

∫[15,24] 426e^(-0.059x) dx

To evaluate this integral, we can use the power rule for integration and the exponential function's properties. The antiderivative of e^(-0.059x) with respect to x is -(1/0.059)e^(-0.059x).

Using the fundamental theorem of calculus, the total expenditures can be calculated as follows:

[-(1/0.059)e^(-0.059x)] evaluated from 15 to 24

After substituting the limits of integration, we can compute the integral and round the result to the nearest billion to obtain the total expenditures between the start of 2015 and the start of 2024.

Var[X] = E[X²] – [E[X]]²The E[X²] is found by integrating x² * f(x) between the limits of 1 and 9.Var[X] = ∫1¹x²/8 dx + ∫9¹x²/8 dx – [5/8]² = 67/192(b) h(E[X]) and E[h(X)]We have h(x) = 1/√x.

Therefore,

E[h(x)] = ∫h(x)*f(x) dx = ∫1¹[1/√x](1/8) dx + ∫9¹[1/√x](1/8) dx = (1/8)[2*√x]|¹9 + (1/8)[2*√x]|¹1 = √9/4 - √1/4 = 1h(E[X]) = h(5/8) = 1/√(5/8) = √8/5(c) Expected value and Variance of Y

Let Y = h(X) = 1/√x.

The expected value of Y is found by using the formula:

E[Y] = ∫y*f(y) dy = ∫1¹[1/√x] (1/8) dx + ∫9¹[1/√x] (1/8) dx

We can simplify this integral by using a substitution such that u = √x or x = u².

The limits of integration become u = 1 to u = 3.E[Y] = ∫3¹ 1/[(u²)²] * [1/(2u)] du + ∫1¹ 1/[(u²)²] * [1/(2u)] du

The first integral is the same as:∫3¹ 1/(2u³) du = [-1/2u²]|³1 = -1/18

The second integral is the same as:∫1¹ 1/(2u³) du = [-1/2u²]|¹1 = -1/2Therefore, E[Y] = -1/18 - 1/2 = -19/36

For variance, we will use the formula Var[Y] = E[Y²] – [E[Y]]². To calculate E[Y²], we can use the formula: E[Y²] = ∫y²*f(y) dy = ∫1¹(1/x) (1/8) dx + ∫9¹(1/x) (1/8) dx

After integrating, we get:

E[Y²] = (1/8) [ln(9) – ln(1)] = (1/8) ln(9)

The variance of Y is given by Var[Y] = E[Y²] – [E[Y]]²Var[Y] = [(1/8) ln(9)] – [(19/36)]²

Answers

y' = 2 - 20t + 13 z'(x) = 10 * (3 * 2^(3/2) - 2^(1/2)) + 6 * (2^(3/2) - 3) * (2^(3/2) - 7x + 8)^(1/2 h'(z) = 9 * (y' * (y - 4) * (2y + y²) + (1 + 2z + 32²) * (5z + 82² - 2³) * (3w + w²)) R'(w) = 4wg'(2) = 10sec²(2) + 2csc²(2) F'(t) = -2 * (4t² - 3t + 2)^(-3)y'(x) = -82/√(1 - 82)T'(2) = -cos(2² + 6) D'(1) = 0Q'(1) = h'(2) + 2

a. To find the derivative of y = 2t - 10t² + 13t, we apply the power rule for differentiation, which states that the derivative of t^n is n * t^(n-1). The derivative of y is y' = 2 - 20t + 13.

b. For the expression z(x) = 10 * √(2³ - √²) + 6 * √(√(2³ - 3) * (42³ - 7x + 8)), we differentiate each term using the chain rule and the power rule for differentiation to obtain z'(x).

c. For h(z) = (1 + 2z + 32²) * (5z + 82² - 2³) * (3w + w²), we differentiate each term with respect to z, and multiply by the derivative of z with respect to w, which is 9(y')(y-4)(2y + y²).

d. R(w) = 2w² + 1 is a polynomial, and the derivative of a polynomial term w^n is n * w^(n-1). Hence, R'(w) = 4w.

e. The function g(2) = 10tan(z) - 2cot(2) involves trigonometric functions, and their derivatives can be found using the trigonometric derivative rules.

f. For 9(t) = (4t² - 3t + 2)^(-2), we apply the chain rule and the power rule for differentiation.

g. The expression y = √(1 - 82) simplifies to y = √(-81), which is not a real number. Therefore, the derivative y'(x) is undefined.

h. For 9(2) = 327 - sin(2² + 6), we differentiate the expression using the chain rule and the derivative of sin(x).

i. The derivative of a constant term is always zero. Hence, D'(1) = 0.

j. To find Q'(1), we differentiate the expression Q(h(2)) with respect to h(2), and then multiply by the derivative of h(2) with respect to Q(1), which is 2.

1 -2 1 e 1.0.3. For the matriz A = 0 0 0 0 1 1 that X₁ = {-3,1,-1) and x₂ = (1,0,0) are eigenvectors of and find their ding eigenvalues.

Answers

For the given matrix A = 0 0 0 0 1 1, the eigenvector X₁ = (-3, 1, -1) has an eigenvalue λ = 1, and the eigenvector X₂ = (1, 0, 0) also has an eigenvalue λ = 1.

To find out if the vectors X₁ = (-3, 1, -1) and X₂ = (1, 0, 0) are eigenvectors of matrix A and determine their corresponding eigenvalues, we need to check if the equation A * X = λ * X holds true for each vector, where A is the given matrix, X is the eigenvector, λ is the eigenvalue, and * denotes matrix multiplication.

Let's start by checking X₁ = (-3, 1, -1):

A * X₁ = 0 0 0   -3   =  0 0 0   (-3, 1, -1)

       0 1 1    1        0 1 1

        = (-3, 1, -1) - 3(1, 0, 0)

        = (-3, 1, -1) - (3, 0, 0)

        = (-6, 1, -1)

To find the eigenvalue λ, we need to solve the equation A * X₁ = λ * X₁:

(-6, 1, -1) = λ * (-3, 1, -1)

By comparing the corresponding components, we get the following equations:

-6 = -3λ

1 = λ

-1 = -λ

Solving these equations, we find that λ = 1 is the eigenvalue corresponding to X₁.

Now, let's check X₂ = (1, 0, 0):

A * X₂ = 0 0 0   1   =  0 0 0   (1, 0, 0)

       0 1 1   0       0 1 1

        = (1, 0, 0)

To find the eigenvalue λ, we need to solve the equation A * X₂ = λ * X₂:

(1, 0, 0) = λ * (1, 0, 0)

By comparing the corresponding components, we get the following equation:

1 = λ

Therefore, λ = 1 is the eigenvalue corresponding to X₂.

In summary, for the given matrix A = 0 0 0 0 1 1, the eigenvector X₁ = (-3, 1, -1) has an eigenvalue λ = 1, and the eigenvector X₂ = (1, 0, 0) also has an eigenvalue λ = 1.

Prove if the series is absolutely convergent, conditionally convergent or divergent. -1)+ n+1 n(n+2) n=1 Hint: Use the fact that n+1 (n+2)

Answers

The given series, Σ((-1)^n+1)/(n(n+2)), where n starts from 1, is conditionally convergent.

To determine the convergence of the series, we can use the Alternating Series Test. The series satisfies the alternating property since the sign of each term alternates between positive and negative.

Now, let's examine the absolute convergence of the series by considering the absolute value of each term, |((-1)^n+1)/(n(n+2))|. Simplifying this expression, we get |1/(n(n+2))|.

To test the absolute convergence, we can consider the series Σ(1/(n(n+2))). We can use a convergence test, such as the Comparison Test or the Ratio Test, to determine whether this series converges or diverges. By applying either of these tests, we find that the series Σ(1/(n(n+2))) converges.

Since the absolute value of each term in the original series converges, but the series itself alternates between positive and negative values, we conclude that the given series Σ((-1)^n+1)/(n(n+2)) is conditionally convergent.
