1.   This Ferris wheel has a 100-foot radius and does not stop to pick up passengers. It revolves slowly enough that Thao and Jennifer can step into a car from a loading platform 10 feet off the ground and sit down as the wheel continues to turn. The location of their car as it travels along its circular path can be modeled by a function where the position of Thao and Jennifer's car is dependent on time. Suppose the Ferris wheel

takes 4 seconds to complete one revolution. Sketch a possible graph of the position of Thao and Jennifer’s car with respect to time. 

Multiple Choice
