A proposed new ride at Disneyland is a Ferris wheel that goes partially undergrand. A preliminary design idea is for the passengers to get on at the bottom of the Ferris wheel which is located 20 below ground. The passengers would then ride to the top of the Ferris wheel located 40 above ground in 20 seconds. Write an equation that would model the proposed Ferris wheel.

Height above ground (in feet) = 10 [ 1 - 3 cos (9t degrees) ]

't' is the time, in seconds, after you sit down and the wheel starts turning.
