(–2, 6) are the points that justify the shaded area

We can substitute the values of x and y from each point into the inequality and check if the inequality is satisfied or not.

Let's check each point:

For points (12, 6):

[tex](y+1)^2/6 -(x+2)^2/24\\ = (6+1)^2/6 - (12+2)^2/24 \\= 49/6 - 196/3 \\= -57.33[/tex]

Here, the value of the expression is less than 1, so this point does not justify the shaded area.

For points (–2, 6):

[tex](y+1)^2/6 -(x+2)^2/24\\ = (6+1)^2/6 - (-2+2)^2/24 \\= 49/6[/tex]

Here, the value of the expression is greater than or equal to 1, so this point does justify the shaded area.

For points (8, –6):

[tex](y+1)^2/6 -(x+2)^2/24 \\= (-6+1)^2/6 - (8+2)^2/24 \\= 25/6-100/24[/tex]

Here, the value of the expression is greater than or equal to 1, so this point does not justify the shaded area.

For point (–1, –2):

[tex](y+1)^2/6 -(x+2)^2/24 \\= (-2+1)^2/6 - (-1+2)^2/24 \\= 1/6 - 1/24 \\= 1/8[/tex]

Here, the value of the expression is less than 1, so this point does not justify the shaded area.

If the talent contest has a total of $1000 in prize money, and there are five prizes to be awarded, we can divide the total prize money by the number of prizes to find the amount of money for each prize.

So, $1000 / 5 = $200 for each prize.

Therefore, the amount of money for each of the five prizes is $200.

To determine the probability that the roots of the given quadratic equation are both real, we need to find the values of a for which the discriminant of the equation is non-negative.

The discriminant of the quadratic equation ax^2 + bx + c = 0 is b^2 - 4ac. In this case, the discriminant of the given equation is:

a^2 - 4(a+35)

For the roots to be real, this discriminant must be non-negative. That is:

a^2 - 4(a+35) ≥ 0

Simplifying this inequality, we get:

a^2 - 4a - 140 ≥ 0

Factorizing the left-hand side, we get:

(a-14)(a+10) ≥ 0

This inequality is satisfied for a ≤ -10 or a ≥ 14, or when a is in the interval [-12, -10) or (14, 15].

Since a is uniformly distributed over the interval [-12, 15], the probability that lies in the interval [-12, -10) or (14, 15] is:

Probability = Length of the interval [-12, -10) + Length of interval (14, 15] / Total length of the interval [-12, 15]
Probability = (2 + 1) / (15 - (-12))
Probability = 3/27
Probability = 1/9

Therefore, the probability that the roots of the given quadratic equation are both real is 1/9.

For rectangular coordinates, the iterated integral would be: ∬R f(x, y) dA = ∫(from a to b) ∫(from c(x) to d(x)) f(x, y) dy dx
For polar coordinates, the iterated integral would be: ∬R f(r, θ) r dA = ∫(from α to β) ∫(from g(θ) to h(θ)) f(r, θ) r dr dθ

To decide whether to use polar coordinates or rectangular coordinates, we need to examine the shape of the region r. If r is a circular or symmetric shape, polar coordinates are often more convenient to use. If r is a rectangular or non-symmetric shape, rectangular coordinates are more appropriate.

Assuming that r is a circular or symmetric shape, we will use polar coordinates. Let's define r in terms of polar coordinates as r = {(r, θ) | 0 ≤ r ≤ a, 0 ≤ θ ≤ 2π}. We can write the double integral of f(x,y) over r in terms of polar coordinates as:

∫∫ r f(x, y) da = ∫₀^a ∫₀^2π f(r cos θ, r sin θ) r dθ dr

This is the iterated integral of f over r in terms of polar coordinates. We integrate f with respect to θ first, from 0 to 2π, and then with respect to r, from 0 to a.

Note that f is an arbitrary continuous function on r, which means that it can take on any value on the region r. We integrate f over r by multiplying f by the area element da, which is r dr dθ in polar coordinates.

To help you with this question, I need to know the specific region R you're referring to. However, I can provide you with general guidance on choosing between polar and rectangular coordinates and setting up an iterated integral.

When deciding between polar and rectangular coordinates, consider the shape and symmetry of the region R. If R has circular or radial symmetry, it's typically easier to use polar coordinates. If R has rectangular or Cartesian symmetry, use rectangular coordinates.

For rectangular coordinates, the iterated integral would be:

∬R f(x, y) dA = ∫(from a to b) ∫(from c(x) to d(x)) f(x, y) dy dx

For polar coordinates, the iterated integral would be:

∬R f(r, θ) r dA = ∫(from α to β) ∫(from g(θ) to h(θ)) f(r, θ) r dr dθ

Answer:140.64\in^{3}

Step-by-step explanation:

To find the equation of the tangent line to the curve y = 5ex cos(x) at the point (0, 5), we need to find the slope of the tangent line at that point.

First, we find the derivative of y with respect to x:

dy/dx = 5ex (-sin(x)) + 5ex cos(x)

Next, we evaluate the derivative at x = 0:

dy/dx |x=0 = 5e0 (-sin(0)) + 5e0 cos(0) = 5

So the slope of the tangent line at (0, 5) is 5.

Now we use the point-slope form of the equation of a line to find the equation of the tangent line:

y - y1 = m(x - x1)

where m is the slope of the line and (x1, y1) is the given point.

Plugging in the values we have:

y - 5 = 5(x - 0)

Simplifying, we get:

y = 5x + 5

So the equation of the tangent line to the curve y = 5ex cos(x) at the point (0, 5) is y = 5x + 5.

Step 1: Find the derivative of the function y.
Given function y = 5e^x cos(x), we will differentiate it with respect to x using the product rule.

Product rule: (uv)' = u'v + uv'
Let u = 5e^x and v = cos(x).

Step 2: Find u' and v'.
u' = d(5e^x)/dx = 5e^x
v' = d(cos(x))/dx = -sin(x)

Step 3: Apply the product rule.
y' = u'v + uv'
y' = (5e^x)(cos(x)) + (5e^x)(-sin(x))
y' = 5e^x(cos(x) - sin(x))

Step 4: Find the slope of the tangent line at the given point (0, 5).
Substitute x = 0 in the derived equation.
y'(0) = 5e^0(cos(0) - sin(0)) = 5(1)(1 - 0) = 5

Step 5: Use the point-slope form to find the equation of the tangent line.
Point-slope form: y - y1 = m(x - x1)
Given point: (0, 5) => x1 = 0 and y1 = 5
Slope (m) = 5

Step 6: Plug the values into the point-slope form.
y - 5 = 5(x - 0)
y - 5 = 5x

Step 7: Rewrite the equation in slope-intercept form (y = mx + b).
y = 5x + 5

The equation of the tangent line to the curve y = 5e^x cos(x) at the point (0, 5) is y = 5x + 5.

Answer:

To solve the quadratic equation x^2 + 9x +25 = 5 by factoring, we first rearrange the equation to get:

x^2 + 9x +20 = 0

Next, we need to find two numbers that multiply by 20 and add to 9, the coefficient of x. The two numbers are 4 and 5.

So, we can factor the quadratic as:

(x + 4)(x + 5) = 0

Setting each factor to zero and solving for x, we get:

x + 4 = 0 or x + 5 = 0

Solving for x in each equation, we get:

x = -4 or x = -5

Therefore, the solutions to the quadratic equation x^2 + 9x +25 = 5 are x = -4 and x = -5.

The graph of the inequality 2x + y > 4 in the coordinate plane is a shaded region above the line 2x + y = 4.

We have,

The given inequality is in the form of the equation of a straight line in two dimensions, but it also includes an inequality.

To graph this inequality on the coordinate plane, we first need to graph the equation of line 2x + y = 4.

We can do this by finding the x and y intercepts of the line.

To find the x-intercept, we set y = 0 and solve for x:

2x + 0 = 4

2x = 4

x = 2

So the x-intercept is (2, 0).

To find the y-intercept, we set x = 0 and solve for y:

2(0) + y = 4

y = 4

So the y-intercept is (0, 4).

Therefore,

The graph of the inequality 2x + y > 4 in the coordinate plane is a shaded region above the line 2x + y = 4.

Let f(x) = x^(1/2), and we want to find f(60). Choose a nearby value of x that is easy to work with, such as x = 64, because f(64) = 8. Now, we will find the derivative of f(x) to determine the rate of change at x = 64.

Now, we'll find f'(64):
f'(64) = (1/2)(64)^(-1/2) = 1/16

Using the linear approximation formula, we have:
f(60) ≈ f(64) + f'(64)(60-64)
f(60) ≈ 8 + (1/16)(-4)
f(60) ≈ 8 - (1/4)

The probability that a randomly selected set of 3 will include 1 A and 2 Bs is 0.3 or 30%.

To find the probability that a randomly selected set of 3 will include 1 a and 2 bs, we first need to determine the total number of possible sets of 3 that can be selected from the sample space.

Since the sample space contains 6 as and 4 bs, the total number of possible sets of 3 that can be selected is:

10C3 = (10!)/(3!*(10-3)!) = 120

This means there are 120 different ways to select a set of 3 from the sample space.

Next, we need to determine the number of sets of 3 that include 1 a and 2 bs. To do this, we can use the combination formula:

6C1 * 4C2 = (6!)/(1!*(6-1)!) * (4!)/(2!*(4-2)!) = 6*6 = 36

This means there are 36 different sets of 3 that include 1 a and 2 bs.

Finally, we can calculate the probability of selecting a set of 3 that includes 1 a and 2 bs by dividing the number of sets that meet this condition by the total number of possible sets:

36/120 = 3/10

Therefore, the probability that a randomly selected set of 3 will include 1 a and 2 bs is 3/10.

Given that the sample space contains 6 As and 4 Bs, let's find the probability that a randomly selected set of 3 will include 1 A and 2 Bs.

1. First, calculate the total number of ways to choose 3 elements from a set of 10 (6 As and 4 Bs). We use the combination formula:

C(n, r) = n! / (r!(n-r)!)
C(10, 3) = 10! / (3!(10-3)!) = 10! / (3!7!) = 120

2. Next, find the number of ways to choose 1 A from the 6 As and 2 Bs from the 4 Bs:

C(6, 1) = 6! / (1!(6-1)!) = 6! / (1!5!) = 6
C(4, 2) = 4! / (2!(4-2)!) = 4! / (2!2!) = 6

3. Multiply the number of ways to choose 1 A and 2 Bs:

Number of favorable outcomes = C(6, 1) × C(4, 2) = 6 × 6 = 36

4. Finally, calculate the probability:

Probability = Number of favorable outcomes / Total number of outcomes = 36 / 120 = 3/10 or 0.3

So, the probability that a randomly selected set of 3 will include 1 A and 2 Bs is 0.3 or 30%.
