Two Ferris wheels are rotating side by side at the Math Fair. The first Ferris wheel has a radius
of Tim and makes one complete revolution everv 16s. The bottom of the wheel is 1.5m above
the ground. The second Ferris wheel has a radius of Em and completes one revolution mrv 2i] 5. The
bottom of this wheel is 12m above the ground. a} Write the equation of a sinusoidal function that models the height of one car as it goes
around the Ferris wheel assuming that the car starts at the minim um at time zero. b} Write the equation of a sinusoidal function that models the height of one car as it goes
around the Ferris wheel assuming that the car starts at the minim um at time zero. c} 1Which car {1 or 2] will be higher at a time of 6 seconds? How much higher? Math
