A community pool that is shaped like a regular pentagon needs a new cover for the winter months. The radius of the pool is 20.10

boyakko [2]

Answer:

$960.42\text{ ft}^2$

Step-by-step explanation:

Please find the attachment.

We have been given that a community pool that is shaped like a regular pentagon needs a new cover for the winter months.

To find the area of community pool we will use area of pentagon formula.

$\text{Area of pentagon}=\frac{1}{2}a*p$ , where, a represents the apothem or perpendicular distance from the center of the pentagon and p represents perimeter of pentagon.

Let us find the perimeter of our given pentagon by multiplying each side length by 5.

$\text{Perimeter of community pool}=5\times 23.62$

$\text{Perimeter of community pool}=118.1$

Now let us find apothem of our pentagon by using Pythagoras theorem.

$a^2=20.10^2-11.81^2$

$a^2=404.01-139.4761$

$a^2=264.5339$

$a=\sqrt{264.5339}$

$a=16.2645$

Upon substituting our given values in above formula we will get,

$\text{Area of community pool}=\frac{1}{2}\times 16.2645\times 118.1$

$\text{Area of community pool}=8.13224907\times 118.1$

$\text{Area of community pool}=960.418615627971\approx 960.42$

Therefore, the area of the pool that needs to be covered is 960.42 square feet.

Which of the following is a factor of f(x) = 3x3 + 8x2 − 87x + 28? (5 points)

N76 [4]

Answer

(x - 4)

Step by step explanation

To find the factors, plug in the x values in the given equation and see which value of x makes the equation equal to zero.

Here (x - 4) is a factor.

Therefore, x = 4

when we plug in x = 4 in the given expression, we get zero.

Let's check it out.

3(4)^3 + 8 (4)^2 - 87(4) + 28

192 + 128 - 348 + 28

348 - 348

0

The answer is (x - 4)

Thank you.

Answer:

CD = 11 units

Step-by-step explanation:

<em>See the drawing attached</em>

<h3>Given</h3>

C is midpoint of AB
B is between A and D
AD = 15
BD = 7
Find CD

<h3>Solution</h3>

CD = CB + BD =
1/2AB + BD =
1/2(AD - BD) + BD =
1/2(15 - 7) + 7 =
1/2(8) + 7 =
4 + 7 =
