Answer:
D; 25
Step-by-step explanation:
√25 = 5
X2 + y2 - 14x + 10y = 250
x2 -14x + 49 - 49 + y2 + 10x + 25 - 25 = 250
(x - 7)^2 - 49 + (y+5)^2 - 25 = 250
(x-7)^2 + (y+5)^2 = 250 + 49 + 25
(x-7)^2 + (y+5)^2 = 324
Therefore the radius, r
r = 324^0.5
r = 18
when is 9 = 15.2 - 0.537x
9 = 15.2 - 0.537x
-15.2 -15.2 subtract 15.2 from both sides
-6.2 = -0.537x
/-0.537 /-0.537 divide -0.537 from both sides
11.55 = x or 12 feet round to nearest whole foot
