he depth of the water, d, at the end of a pier changes periodically as a function of time, t, in hours as shown in the graph below. According to the model, the last low tide occurred at 5:00 a. m. When will the next low tide occur? Let t = 0 be 12:00 a. m. On a coordinate plane, a curve crosses the y-axis at (0, 6). It decreases to (5, 2) and then increases to (10, 6). 3:00 a. m. 5:00 a. m. 3:00 p. m. 5:00 p. m.seen by an observer at the takeoff point. Round to the nearest degree. a. 75º b. 15º c. 76º d. 14º
