Can you help me? Please!

The tide at a beach increases and decreases in a predictable, sinusoidal pattern. High tide reaches 14 feet above the base of a dock at 2:00 AM, and low tide is 2 feet above the base of the dock at 8:30 AM.

a.What is the equation for the height of the water at any given time (Hint: Make Midnight be t = 0 so that you can assign values to the times in the question)

b.What is the height of the water at 6:30 AM?

c.When the water is less than 6 feet high, people can go out in the water and draw on the dock. When is the first range of time that they can do that?
