3) Systolic blood pressure is the blood pressure in a body when the heart contracts. An animal undergoing laboratory testing was injected with an experimental drug. The animal's systolic blood pressure $P$ (in millimeters of mercury) was found to be given by $P = \frac{21}{(t+1)^2} + 100$; $0 \le t \le 4$, where $t$ was the number of hours after the injection. What was the average systolic blood pressure over the first two hours after the injection? (107 mm of mercury)

Given: Blood pressure is measured when the blood is pumping (systolic) and when the heart is resting (diastolic). When pressure readings are given, the systolic is given first, and healthy blood pressure is around 120 over 80 mm Hg. Recall the density of mercury is 13.6 × 103 kg/m3. Suppose you have a blood pressure reading of 119 over 83 mm Hg. What is your systolic pressure, in newtons per meter squared? Suppose you have a blood pressure reading of 119 over 83 mm Hg. What is your diastolic pressure, in newtons per meter squared?

Blood pressure: A blood pressure measurement consists of two numbers: the systolic pressure, which is the maximum pressure taken when the heart is contracting, and the diastolic pressure, which is the minimum pressure taken at the beginning of the heartbeat. Blood pressures were measured, in millimeters of mercury (mmHg), for a sample of 10 adults. The following table presents the results. Use a TI-84 calculator to answer the following. Systolic Diastolic Systolic Diastolic 115 83 130 76 113 77 116 70 123 77 133 91 119 69 112 75 118 88 107 71 Based on results published in the Journal of Human Hypertension

When pressure readings are given, the systolic is given first, and healthy blood pressure is around 120 over 80 mm Hg. Recall the density of mercury is 13.6 × 103 kg/m3. a) Suppose you have a blood pressure reading of 121 over 76 mm Hg. What is your systolic pressure, in newtons per meter squared? b) Suppose you have a blood pressure reading of 121 over 76 mm Hg. What is your diastolic pressure, in newtons per meter squared?
