Entertainment As you ride a ferris wheel, the height that you are above the ground varies periodically. Consider the height of the center of the wheel to be the equilibrium point. Suppose the diameter of a ferris wheel is 42 feet and travels at a rate of 3 revolutions per minute. At the highest point, a seat on the ferris wheel is 46 feet above the ground.
a)What is the lowest height of a seat?
b)What is the equation of the midline?
c)What is the period of the function?
d)Write a sine equation to model the height of a seat that was at the equilibrium point g=heading upward when the ride began.
