I Need To Find The Slope Of Each Line And Show My Work For It

Answers

Answer 1

Answer:

3) m = -3/2

4) m = 3/2

5) m = 5/3

6) m =  7/3

7) m = -3

8) m = 7/3

Step-by-step explanation:

Slope = rise/run or (y2 - y1) / (x2 - x1)

3/ ( -4, 0) ( -2, -3)

The y decrease by 3, and the x increase by 2, so the slope is

m = -3/2

4/ (2,0) (0, -3)

The y decrease by 3, and the x decrease by 2, so the slope is

m = -3/-2 = 3/2

5/ (-1,2) (-4, -3)

The y decrease by 5, and the x decrease by 3, so the slope is

m = -5/-3 = 5/3

6/ (4,3) (1, -4)

The y decrease by 7, and the x decrease by 3, so the slope is

m = -7/-3 = 7/3

7/ (1,2) (3, -4)

The y decrease by 6, and the x increase by 2, so the slope is

m = -6/2 = -3

8/ (0,3) (-3, -4)

The y decrease by 7, and the x decrease by 3, so the slope is

m = -7/-3 = 7/3

The first 4 terms of the sequence by the given recursive formula is found as: 6 , 13, 20, 27.

Explain about the recursive formula?A straightforward illustration of either a recursive function is the factorial, which multiplies a number by itself while lowering it slowly. Recursive functions can refer to a wide variety of self-referential looping functions, such as those whereby n = n + 1 assuming an operational range.

For the stated question:

f(n) :

f(1) = 6

f(n) = f(n - 1) + 7, if n > 1.

Thus,

First term, n = 1: f(1) = 6

Second term, n = 2:  

f(2) = f(2 - 1) + 7

f(2) = f(1) + 7

f(2) = 6 + 7

f(2) = 13

Third term: n = 3.

f(3) = f(3 - 1) + 7

f(3) = f(2) + 7

f(3) = 13 + 7

f(3) = 20

Fourth term: n = 4.

f(4) = f(4 - 1) + 7

f(4) = f(3) + 7

f(4) = 20 + 7

f(4) = 27

Thus, the first 4 terms of the sequence by the given recursive formula is found as: 6 , 13, 20, 27.

if the world population is 7.0 billion in 2012, and the growth rate is constant at 1.4%, calculate the population in 2030.

Answers

The world population in 2030 will be of 9.0062 billion.

The exponential formula for population growth is given below:

P(t) = P (0)e^rt

Here, P(t) is the population in t years from now P (0) is the population in the current year and r(decimal) is the growth rate, e=2.7 is the Eular number.

If the world population is 7.0 billion in 2012.

2012 is the initial year, P (0) =7

P(t) will be measured in billions of people.

The growth rate is constant at 1 .4%.

So that, r = 0.014

Now, the population in 2030 will be :

2030-2012=18 years after 2012, so this is P(18).

P(t)= 7e^rt

P(18) = 7e^0.0014*18

The z-score for an observation of 200 is approximately -2.000.

Z-Value for Observation 200

Here are the steps to calculate the z-score for an observation of 200 based on a normal distribution with a mean of 500 and a standard deviation of 150:

Subtract the mean (μ) from the observation (x):

        x - μ = 200 - 500 = -300

Divide the result from step 1 by the standard deviation (σ):

        -300 / 150 = -2

Round to the nearest thousandth to get the final z-score:

        -2 ≈ -2.000

So, the z-score for an observation of 200 is approximately -2.000.

A z-score is a measure of how many standard deviations a given value is from the mean of a dataset. It is calculated by subtracting the mean of the dataset from a given value and dividing the result by the standard deviation of the dataset.

In the case of a normal distribution with a mean of 500 and a standard deviation of 150, a z-score of -2 would indicate that an observation of 200 is 2 standard deviations below the mean. This information can be used to determine the proportion of data within the dataset that is above or below a certain value, or to make comparisons between different datasets.

A graph is defined by the equation y²(2 - x) = x³. find the x- or y-value of each point where the slope of the original equation is undefined.

Answers

The value of x and y for which the graph has undefined slope is y = 0 or x = 2

Given y²(2 - x) = x³

We are asked to determine the point on the curve which has an undefined slope.

Undefined slope means dy/dx = ∞

                                   Now, y²(2 - x) = x³

                               Differentiating both sides

                                   2y dy/dx (2-x) - y² = 3x²

                                                       dy/dx = (3x² + y²)/2y(2-x)

So, (3x² + y²)/2y(2-x) = ∞

For this 2y(2-x) = 0

We can see that the possible cases  y = 0 or x = 2

Hence for y = 0 or x = 2, the slope of the graph is undefined.

solve the following initial value problems for y(t) by antidifferentiation or by aseparation of variables: dy dt = y t cos( ) y; y(0) = 2

Answers

y(t) = 2e^(sin(t) + t) is the antiderivative of the function dy/dt = y cos(t) + y, and satisfies the initial condition y(0) = 2.

This is a first-order linear differential equation, which can be solved by the separation of variables. To do so, we can start by writing:

dy/dt = y cos(t) + y

We can divide both sides by y:

dy/dt / y = cos(t) + 1

Now, we can integrate both sides with respect to t, using the property that d(ln y)/dt = 1/y:

∫(dy/dt / y) dt = ∫(cos(t) + 1) dt

ln|y| = sin(t) + t + C

Where C is the constant of integration. To find its value, we can use the initial condition y(0) = 2:

ln|2| = sin(0) + 0 + C

C = ln|2|

Therefore, the solution of the initial value problem is:

y(t) = 2e^(sin(t) + t)

This is the antiderivative of the function dy/dt = y cos(t) + y and satisfies the initial condition y(0) = 2.

Answers

The pedestrian crossing sign is a parallelogram because both pairs of opposite sides are parallel. The Second option is Correct.

A parallelogram is a quadrilateral that has two pairs of parallel sides, meaning that both sets of opposite sides are parallel. This is opposed to a trapezoid, which has only one pair of parallel sides. The pedestrian crossing sign is typically in the shape of a parallelogram, with the top and bottom sides being parallel, and the sides slanting towards each other to form a point at the top.

This design helps the sign to be easily visible from a distance and clearly recognizable as a pedestrian crossing sign. The parallel sides of the sign are an important characteristic that helps drivers and pedestrians to identify and understand the meaning of the sign.

Mr Houston bought a new car for £18500 in July 2010.
Its value depreciated by 15% in the first year, 18% in the
second year and 25% in the third year.
By how much had its initial price fallen by July 2013?

Answers

The percentage decrease from first to third year is; 47.725%

How to calculate percentage decrease?

To find the percentage decrease, work out the difference (decrease) between the two numbers you are comparing. Thereafter, divide the decrease by the original number and then multiply the answer by 100.

Amount of car in 2010 = £18500

It depreciated by 15% in the first year. Thus;

Amount after first year = (100% - 15%) * 18500

= £15725

It depreciated by 18% in the second year. Thus;

Amount after second year = (100% - 18%) * 15725

= £12,894.5

It depreciated by 25% in the third year. Thus;

Amount after third year = (100% - 25%) * 12,894.5

= £9,670.875

Thus;

Decrease from first to third year = (18500 - 9670.875)/18500 * 100%

= 47.725%

Practice 7-3 Constructing Bisectors (PLEASE HELP)

Therefore , the solution of the given problem of angle bisector  comes out to be each measurement will be equivalent to 30 degrees,

What is an Angle Bisector?

A bisector exists for each angle. Additionally, it is the symmetry line that connects an angle's two arms, triangle  whose construction facilitates the creation of smaller angles.

Here,

A 30° angle, for example, might be called for. A 60° angle can be made, and it can then be divided, to accomplish this.

The concept of an angle bisector is used to construct angles such as 90 degrees, 45 degrees, 15 degrees, and others.

Examples :

What is each angle's measurement if an angle bisector divides an angle of 80 degrees?

The answer is that 80 degrees is the measure of an angle.

It is common knowledge that the angle is divided into two equal pieces by the angle bisector.

Consequently, 80 degrees is divided into two equal portions, let's call x.

Hence,

x + x = 80°

2x = 80°

x = 80°/2

x = 40°.

The second option is ineffective since it would result in A' being positioned at (-5, 2) after translation A 3 up and 1 left (5, -2).

The third option: spinning A in a clockwise direction 90 degrees places it at (-1, 4), then reflecting it across the y-axis places it at (1, 4).

In the fourth option, A is rotated 90 degrees counterclockwise, putting it at (1, -4), and it is reflected across the x-axis, putting it at (1, 4).

The fifth option is to rotate A 180 degrees, which positions it at (-3, -4), after translating 3 down & 1 right (3, 4). B(-5, -5) (-5, -5)  Translated results in (-4, -8), and rotated results in (4, 8). Translation of C(-3, -4) results in (-2, -7), and rotation results in (2, 7).

The absolute minimum value of y =-cos(x) - sin(x) on the closed interval [0, π/2] is  [tex]-\sqrt{2}[/tex]

Consider equation,

y = -cos(x) - sin(x)

Let y = f(x)

Differentiate the function f(x) = -cos(x) - sin(x) with respect to x.

f'(x) = -(-sin(x)) - cos(x)

f'(x) = sin(x) - cos(x)

For f'(x) = 0,

sin(x) - cos(x) = 0

sin(x) = cos(x)

sin(x)/cos(x) = 1

tan(x) = 1                     ..............(tan(θ) = sin(θ)/cos(θ))

x = π/4

For above value of x, the value of function would be,

f(π/4) = -cos(π/4) - sin(π/4)

f(π/4) = [tex]-\frac{1}{\sqrt{2} } -\frac{1}{\sqrt{2} }[/tex]

f(π/4) = [tex]-\sqrt{2}[/tex]

f(0) =  -cos(0) - sin(0)

f(0) = -1

a triangle has an area of 16 in2, and two of the sides of the tri- angle have lengths 5 in. and 7 in. find the angle included by these two sides.

Answers

The angle included by these two sides is (c^2 - 74) / (-70).

What is triangle ?

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted triangle ABC.

The area of a triangle can be found using the formula:

Area = (1/2) * b * h,

where b is the length of the base and h is the height of the triangle.

Since two of the sides have lengths 5 in and 7 in, we can assume that they are the base and the height of the triangle, respectively. Setting b = 5 in and h = 7 in, we can find the area:

Area = (1/2) * 5 in * 7 in = (1/2) * 35 in^2 = 16 in^2.

This means that the height of the triangle is 7 in and the base is 5 in. To find the angle included by these two sides, we can use the Law of Cosines:

c^2 = a^2 + b^2 - 2ab * cos(C),

where a and b are the lengths of the sides and C is the angle included by these two sides.

Since a = 5 in and b = 7 in, we can find the angle C:

c^2 = a^2 + b^2 - 2ab * cos(C)

c^2 = 5^2 + 7^2 - 2 * 5 * 7 * cos(C)

c^2 = 25 + 49 - 70 * cos(C)

c^2 = 74 - 70 * cos(C)

So , The angle included by these two sides is (c^2 - 74) / (-70).

The slope of the curve at P is -60, and The equation for the tangent line at P is 60x + y = 245.

a) To find the slope of the curve, the derivative of a function f(x) at the given point is a slope of the curve

Slope of the given curve y = -5 - 2x² at the point P(5, -55) is the derivative f'(x) at P(5, -55)

m = f'(x) = dy/dx

= 0 - 2(2x)

Since the derivative of a constant is zero and the derivative of x² is 2x

f'(x) at P(5, -55) is 0 - 6(2 × 5)

= 0 + (- 6 × 10) = -60

b) To find an equation of the tangent line at P(5, -55) for the curve y = -5 - 2x²

The equation of tangent line in for the function f(x) at P (x1, y1) is (y - y1) = m (x - x1)

x1 = 5 and y1 = -55, f(x) = -5 - 2x² and slope of tangent m = -60

The equation of the tangent line is (y + 55) = - 60(x - 5)

Energy requirement (kcal/km) = Fuel consumption (gal/km) * Energy released per gallon (kcal/gal)

Energy requirement (kcal/km) = (1 / 38) * (3 x 10^4 kcal/gal)

Now,

Fuel consumption (gal/km) = 1 / 38

Energy requirement (kcal/km) = (1 / 38) * (3 x 10^4 kcal/gal)

Energy requirement (kcal/km) = (1 / 38) * (3 x 10^4 kcal/gal)

≈ 789.47 kcal/km

Therefore,

The approximate energy requirement for the car when driven at 95 km/h is 789.47 kcal/km.

What is percent?

A % is a relative figure that represents the hundredth part of any amount. One percent (symbolized 1%) is one hundredth part; consequently, 100 percent denotes the complete amount and 200 percent defines twice the supplied amount. percentage. Mathematics percentile is a related topic. A percentage is a fraction of a whole represented as a number between 0 and 100. Nothing is zero percent, everything is 100 percent, half of everything is fifty percent, and nothing is zero percent. To calculate a percentage, divide the share of the total by the total and multiply by 100.

A more detailed version of Theorem I says that, if the function f (x, y) is continuous near the point (a, b), then at least one solution of the differential equation y' = f(x, y) exist on some open interval I containing the point x = a and moreover, that if in addition the partial derivative partial differential f/partial differential y is continuous near (a, b), then this solution is unique on some (perhaps smaller) interval J. In Problems 11 through 20, determine whether existence of at least one solution of the given initial value problem is thereby guaranteed and, if so, whether uniqueness of that solution is guaranteed. dy/dx = 2x^2y^2: y(1) = -1 dy/dx = x ln y: y(1) = 1 dy/dx = cubicroot y: y(0) = 1 dy/dx = cubicroot y: y(0) = 0 dy/dx = Squareroot x- y: y(1) = 2 dy/dx = Squareroot x - y: y(2) = 2 dy/dx = Squareroot x - y: y(2) = 1 y dy/dx = x - 1: y(0) = 1 y dy/dx = x - 1: y(1) = 0 dy/dx = ln(1 + y^2): y(0) = 0 dy/dx = x^2 - y^2: y(0) = 1

Step-by-step explanation:

buckley farms decides to increase the mean weight of each bag of chips so that only 5% of the bags have weights that are less than 16 ounces. assuming that the standard deviation remains 0.12 ounce, what mean weight should buckley farms use?

Answers

Assuming that the standard deviation remains 0.12 ounces, so 16.251 ounces mean weight should Buckley Farms use.

The total weight of each bag follows an approximately normal distribution with a mean of 16.15 ounces and a standard deviation of 0.12 ounces.

Mean (μ) = 16.15

Standard deviation, (σ) = 0.12

n = 6

Buckley Farms decides to increase the mean weight of each bag of chips so that only 5%(0.05) of the bags have weights that are less than 16 ounces. So

P(X > x) = 0.05

P[(X - μ)/(σ/√n) > (x - μ)/(σ/√n)] = 0.05

1 - P(Z ≤ z) = 0.05

Subtract 1 on both side , we get

P(Z ≤ z) = 0.95

z = 1.96

(x' - μ)/(σ/√n) = 1.645

Now putting the value

(x' - 16.15)/(0.15/√6) = 1.645

(x' - 16.15)/(0.15/2.45) = 1.645

(x' - 16.15)/(0.0612) = 1.645

Multiply by 0.0612 on both side, we get

x' - 16.15 = 0.100674

Add 16.15 on both side, we get

x' = 16.251
