Which equation is equivalent to the formula below?

B-is correct

Step-by-step explanation:

y=a(x-h)^2+k

-k               -k

y-k=a(x-h)^2

:(x-h)^2    :(x-h)^2

(y-k)/(x-h)^2 =a

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
