Question

27)

What is the center of the circle represented by this equation?

x2 + (y + 9)2 = 25
A) (3, 5)
B) (0, 25)
C) (9, 25)
Eliminate
D) (0, -9)

Help is appreciated!

Answer 1

The center is (0, -9) and the radius is 5

Explanation:

Answer 2

The center is (0, -9) and the radius is 5

Explanation:

The equation of a circle can be written as

(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius

x^2 + (y + 9)^2 = 25

(x-0)^2 + (y- -9)^2 = 5^2

The center is (0, -9) and the radius is 5
