The depth of the water in a bay varies throughout the day with the tides. Suppose that we can model the depth of the water with the following function.h(t)= 20+5.5 cos 0.25t
In this equation, ht is the depth of the water in feet, and t is the time in hours.
Find the following. If necessary, round to the nearest hundredth.
Number of tidal cycles per hour :
Minimum depth of the water : feet
Time between consecutive high tides: hours
