The Colossus Ferris wheel debuted at the 1984 New Orleans World's Fair. The ride is 180 ft tall, and passengers
board the ride at an initial height of 15 ft above the ground. The height above ground, h, of a passenger on the
ride is a periodic function of time, t. The graph displays the height above ground of the last passenger to board
over the course of the 15 min ride.

Time of operation, t (min)
Sine function model: h = −82.5 cos (3πt) + 97.5 where h is the height of the passenger above the ground
measured in feet and t is the time of operation of the ride in minutes.
What is the period of the sine function model? Interpret the period you found in the context of the operation of
the Ferris wheel.
