Each time your heart beats, your blood pressure first increases
and then decreases as the heart rests between beats. The maximum
and minimum blood pressures are called the systolic and
diastolicpressures, 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) = 130 + 25 sin(150πt)
where p(t) is the pressure in mmHg (millimeters of mercury), at time t measured in minutes.
(a) Find the period of p.
min
(b) Find the number of heartbeats per minute.
heartbeats per minute
(c) Graph the function p.
(d) Find the blood pressure reading.
systolic/diastolic = /
How does this compare to normal blood pressure?
This reading is lower than normal.This reading is normal. This reading is higher than normal.

When reporting your vital signs be sure to measure heart rate in
beats per minute, respiration rate in breaths per minute and blood
pressure as systolic/ diastolic in mmHg (these measurements should
look like 120/70). You can do this lab on yourself or on someone
else.

per minute and average the results

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, for a sample of adults.
The following table presents the results.

A physician claims that a person's diastolic blood pressure can
be lowered if, instead of taking a drug, the person meditates each
evening. Ten subjects are randomly selected and pretested. Their
blood pressures, measured in millimeters of mercury, are listed
below. The 10 patients are instructed in basic meditation and told
to practice it each evening for one month. At the end of the month,
their blood pressures are taken again. The data are listed below.
