Answer:
The answer to your question is x ² + y² = 64
Step-by-step explanation:
Process
1.- Find the length of the radius
C (0, 0)
P (0, -8)
d = 
d = 
d = 
d = 8
2.- Find the equation of the circle

h = 0 and k = 0

x² + y² = 64
Answer:
1. A possible solution for x +y is 9
Step-by-step explanation:
A possible solution for m-n is 0
Answer:
16/21
Step-by-step explanation:
Answer: x = 5/7
Step-by-step explanation:
The numerator is the power, while the denominator is the index (thing next to radical).
Answer:
Convergent; 81
Step-by-step explanation:
r = term2/term1 = 8/9
8/9 < 1 so convergent
Sum = 9/(1 - 8/9)
= 9/(1/9) = 81
