Question

A boat tied up at a dock bobs up and down with passing waves. The vertical distance between its high point and its low point is 8m and the cycle is repeated every 4 seconds. When the boat is at its lowest point, it is 7m above the ocean floor.

a) If time starts when the boat is at its lowest position, determine a sine and cosine equation to model the height of the boat above the ocean floor, in meters, versus the time, in seconds.
