Abuoy 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?

The answer is a. h=4sin(pi/6)t

This problem is deemed to be incomplete. we cannot give a direct answer to your problem since we do not have the choices (equations) but we can have a general approach in answering this problem. we can assume that the equation has 2 variables (x and y) or (t and h) respectively. whichever equation satisfies the condition: when x= 0, y=6, then that equation is the answer.
