The paddle wheel of a boat measures 16 feet in diameter and is revolving at a rate of 20 revolutions per minute. The maximum depth of the paddle wheel under water is 1
foot. Suppose a point is located at the lowest point of the wheel at t=0. Write an
equation for the height of the initial point after t seconds.

Graph the system: f(x)= 3/x-2; f(x)= 1/2x + 2
