9. A loop on a roller coaster has its highest point at 42 m and it's lowest point at 18 m. If the height of a cart on the loop of the roller coaster were modelled by a sine or cosine function, what would the amplitude be? a. 30 m b. 12 m C. 24 m d. 7 m 10. The height, h, in metres, above the ground of a car as a Ferris wheel rotates can be modelled by the function h(t) = 16 cos(1.5t) + 18, where t is the time, in seconds. What is the maximum height of a car? a. 18 m b. 26 m C. 34 m d. 16 m
