Question 1058094: The pressure P (in pounds per square foot), in a pipe varies over time. Ten times an hour, the pressure oscillates from a low of 30 to a high of 250 and then back to a low of 30. The pressure at time t=0 is 30. Let the function P=f(t) denote the pressure in pipe at t minutes. Find a possible formula for the function P=f(t) described above. Remember to use t as your input value.
