Answer:
A Ferris wheel has a diameter of 380 feet and the center of the wheel is 195 ... the height h (in feet) of a passenger on the wheel as a function of time t ... 1 Expert Answer ... Now generally a cosine function starts at the maximum value, so to ... minimum value, there is no phase shift so C/B = 0, meaning C = 0.Step-by-step explanation:
