3. At a certain ocean bay, the maximum height of the water is 4 m above mean sea level at 8:00 a.m. The height is at a maximum again at 8:24 p.m. Assuming that the relationship between the height, h, in metres, and the time, t, in hours, is sinusoidal, determine the height of the water above mean sea level at 10:00 a.m. ✓✓✓✓✓ Test Summary Knowledge & Thinking & Invest.
