The pressure, P (in lbs/ft2), in a pipe varies over time. Five times over the span of 60 minutes, pressure oscillates from a low of 90 to a high of 230 and then back to a low of 90 (this whole sequence happens 5 times). The pressure at t = 0 is 90. Complete the equation y = A cos(Bt) + k, by giving values for A, B, and k, where t is time in minutes.
