A buoy starts at a height of 0 in relation to sea level and then goes up. Its maximum displacement in either direction is 6 feet, and the time it takes to go from its highest point to its lowest point is 4 seconds. Which of the following equations can be used to model h, the height in feet of the buoy in relation to sea level as a function of time, t, in seconds?
h = 4 sine (StartFraction pi Over 6 EndFraction t)
h = 4 sine (StartFraction pi Over 3 EndFraction t)
h = 6 sine (StartFraction pi Over 4 EndFraction t)
h = 6 sine (StartFraction pi Over 2 EndFraction t)
