Find the equation of the circle whose center and radius are given.
center (0,8), radius = 8

Step-by-step explanation:

The equation of the circle with center at point and radius r is

In your case,

So, the equation of the circle with center at (0,8) and radius r=8 is

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
