As you ride the Ferris wheel, the distance above the ground varies sinusoidally with time. Let (t) be the number of seconds that has elapsed since the Ferris wheel started. When the last seat is filled (that's you), the wheel starts. It takes 6 seconds to reach the maximum height of 46 feet above the ground. The wheel has a diameter of 44 feet and makes one revolution every 12 seconds. Write a cosine function to model the height above the ground at any time (t).
