Me with over a 24-hour period, the tide in a harbor can be modeled by one period of a sinusoidal function. the tide messures 5.15 ft at midnight, rises to a high of 10.2 ft, falls to a low of 0.1 ft, and then rises to 5.15 ft by the next midnight. what is the equation for f(x), where x represents time in hours since the beginning of the 24-hour period, that models the situation? show your work and explain.
