Rasek [7]

Answer:

see below

Step-by-step explanation:

1. 0 = (r + 1)(r + 8)

Using Zero Product Property, r = -1, r = -8

2. h(r) = (r + 1)(r + 8)

         = r² + 9r + 8

         = (r + 9/2)² - 81/4 + 8

         = (r + 4.5)² - 12.25 (Complete the square)

   Vertex: (-4.5, -12.25)

Solve the equation for y. Then find the value of Y for each value of X.
Hunter-Best [27]

Answer:

y=9-7x

If x= -1, y=16

If x= 0, y=9

If x=2, y= -5

Step-by-step explanation:

Because you are solving the equation for y, you want to have y by itself on one side. The only way to do that in this problem is by subtracting the 7x on both sides.

y+7x=9

-7x -7x ---> y=9-7x

The next part of the question says to find the value of Y for each value of X. Using the given X values, we plug them into the equation we just got in order to find Y.

y=9-7(-1) ----> y=16

y=9-7(0) ----> y=9

y=9-7(2) ----> y=-5

Find the area of the circle with the given radius or diameter. Use pi = 3.14. d = 13 A=?
GuDViN [60]
Hello!

The formula for finding area of a circle is: π · r²

Diameter is 2x the radius. To find the radius when the diameter is given, divide the diameter by 2.

The diameter is 13. 13 ÷ 2 = 6.5

r = 6.5
6.5² = 6.5 × 6.5 = 42.25

π = 3.14

Multiply 3.14 by 42.25 to get the area

3.14 × 42.25 = 132.665

<em>The area of the circle is 132.665 sq. units, which is the last option.</em>
