With each heartbeat, blood pressure increases as the heart contracts, then decreases as the heart rests between beats. The maximum blood pressure is call- the systolic pressure and the minimum blood pressure is called diastolic pressure. When a doctor records an individual's blood pressure such as "120 over 8C is understood as "systolic over diastolic". Suppose that the blood pressure for a certain individual is approximated by p () = 80 + 30 sin (160nt) where p is th blood pressure in mmHg (millimeters of mercury) and t is the time in minutes after recording begins. (a) Find the period of the function and interpret the results. (b) Find the maximum and minimum values and interpret this as a blood pressure reading. (c) Find the times at which the blood pressure is at its maximum. Part 1 of 3 (a) Find the period of the function and interpret the results. The period is minutes and represents the time for one complete heartbeat. olo
