Kevin is riding a mini Ferris wheel. He reaches the maximum height of 9m at 5s and then reaches the minimum height of 1m at 65s. 

a. What is the period (the length of time to complete one cycle)?      5 seconds + 65 seconds = 70 seconds.
                                                                       Although the condition does not give a direct and explicit info, 
                                                                       I make this conclusion, because there is no other alternatives.


b. what is the radius of the wheel?                                     = 4 m.


c. sketch one cycle of the function. Label the graph.	               Of which function ?	


d. the corresponding cosine equation:

I am glad that you found and fixed the error of the previous version after my notice.
