At a seaport, the relationship between water depth (d) and time (t) is sinusoidal. Write a sinusoidal equation given the following information about the water depth. There is a maximum depth of 18 m at 3:00 am and a
minimum depth of 4 m is at 9:30 am. Assume t is the number of hours after midnight.
