(4 points) A ferris wheel is 140 meters in diameter and boarded at its lowest point (6 O'Clock) from a platform which is 20 meters above ground. The wheel makes one full rotation every 12 minutes, and at time t = 0 you are at the highest point on the ferris wheel (at 12 O'Clock). Let h = f(t) denote your height above ground in meters after t minutes. (a) What is the period of the function h = f(t)? period = Include units in your answer. (b) What is the midline of the function h = f(t)? h = Include units in your answer. (c) What is the amplitude of the function h = f(t)? amplitude = Include units in your answer. (d) Consider the six possible graphs of h = f(t) below. Be sure to enlarge each graph and carefully read the labels on the axes in order distinguish the key features of each graph
