Asked by Dena
The circular path of cars on a ferris wheel can be modeled with the equation x^2-14x+y^2-150y=-49, measured in feet. What is the maximum height above ground of the riders.

write the circle equation in standard form by completing the square
x^2 - 14x + 48 + y^2 - 150y + 5625 = -49 + 49 + 5625
(x-7)^2 + (y - 75)^2 = 75^2
so the centre is at (7, 75) and the radius is 75
