## Homework Statement

The Ferris wheel at a carnival has a diameter of 18m and descends to 2m above the

ground at its lowest point. Assume that a rider enters a car at this point and rides the wheel

for two revolutions

(A) model the riders height above the ground vs the angle of rotation using a transformed sime function.

## Homework Equations

## The Attempt at a Solution

I know the answer is y= 9 sin (x-90) + 11

I know the a is 9 because the 18/2 and the c value is 11 because 2 + 9 = 11 but I don't know how they got to (x - 90)
