Answer:
z = 1
Step-by-step explanation:
90/15 = 6/z
Cross Multiply
15 * 6 = 90 * z
90 = 90z
Divide both sides of the equation by 90
z = 1

Answer:
(0,-9)
Step-by-step explanation:
The equation of a circle is written in the form
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
Rewriting
x² + (y + 9)^2 = 25
(x-0)² + (y - - 9)^2 = 5^2
We find the center is (0,-9) and the radius is 5
