The water level rises and falls daily in Chesapeake Bay. On a certain day, the depth of the water at the naval dock in Annapolls is modeled by D (t) = 18 + 2 sin(0.5t) Where D is measured in feet and t is time in hours after midnight. The argument of the cosine function is in radians. What is the rate of change in the depth of the water after 6 hours. Round your answer to 2 decimal places. a. 0.14 b. 17 C. -0.99 d. -0.14
