The depth of water in a tank oscillates every 5 hours. The smallest depth is 0.5, and that the largest depth is 7.5. Find a formula for the depth as a function of time t measured in hours for which the depth at time t=0 is the largest depth.

So the amplitude is 7.5-.5/2 which is 3.5?

|dw:1443488404092:dw|We start at our highest point.
And you've calculated the amplitude correctly, ok good!
