The figure shows the depth of water at the end of a boat dock. The depth is 8 feet at low tide and 16 feet at high tide. On a certain day, low tide occurs at 6 AM and high tide at noon. If y represents the depth of the water x hours after midnight, use a cosine function of the form y=AcosBx+D to model the water's depth. Write the equation for this problem in the form y=AcosBx+D.
