Answer 3

On a particular day Labor Day, the high tide in Southern California occurs at 7:12 A.M. At that time you measure the water at the end of the Santa Monica Pier to be 11 ft deep. At 12:14 P.M. it is low tide and you measure the water to be only 7 ft deep. Assume the depth of the water is a sinusoidal function of time with a period of 1/2 lunar day, which is about 12 hours and 24 minutes.

a. Write the equation to model this problem.

b. At what time on Labor Day does the first low tide occur?

c. What is the approximate depth of the water at 9:00 P.M.?

d. What is the first time on that Labor Day that the water is 9 ft deep?
