- 1.Tides are a periodic rise and fall of water in the ocean. At a seaport, the water has a minimum depth of 4m at 3:00 am. After this minimum depth, the first maximum depth of 20m occurs at 10:30 am.a)Graph how the depth of the tide flow varies with respect to the time in a day.b)Determine a sinusoidal function for the water depth at any time t.c)What is the water depth at 6:45pm?d)A cruise ship needs at least 9m of water to dock safely. Estimate the number of hours in the 24 hour interval during which the cruise ship can dock safely.
