II. John is floating on a tube in a wave tank. At t = 1 sec, John reaches a maximum height of 14m above the bottom of the pool. At t = 9 sec, John reaches a minimum height of 2m above the bottom of the pool. 7. Sketch a graph below which expresses John's 8. Write an equation for h, the height of John's height from the bottom of the pool with respect float, as a cosine function of time, t. to time. 9. What is the height after 30 seconds?
