A ferris wheel is 15 meters in diameter and boarded from a platform that is 5 meters above the ground. The six o'clock position on the ferris wheel is level with the loading platform. The wheel completes 1 full revolution in 4 minutes. The function h = f(t) gives your height in meters above the ground t minutes after the wheel begins to turn. Amplitude -------- Minutes  Midline ------ Minutes  period ----- minutes  How high are you off of the ground after 2 minutes --- meters  answers are  7.5 12.5 4 20  please explain neatly , thank you !
