(c) Graph the function v. 85. Blood Pressure Each time your heart beats, your blood pres- sure first increases and then decreases as the heart rests between beats. The maximum and minimum blood pressures are called the systolic and diastolic pressures, respectively. Your blood pressure reading is written as systolic diastolic. A reading of 120/80 is considered normal. A certain person's blood pressure is modeled by the function p(t) = 115 + 25 sin(1607) where p(1) is the pressure in mmHg (millimeters of mer- cury), at time i measured in minutes. (a) Find the period of p. (b) Find the number of heartbeats per minute. (c) Graph the function p. (d) Find the blood pressure reading. How does this compare to normal blood pressure?
