In reading blood pressure (BP) there are always two numbers present. When your heart beats the first number, the systole, indicates the pressure (measured in mm Hg) exerted by the blood along the walls of your arteries. It is the peak blood pressure during active heart contractions. The second number, the diastole, is the pressure exerted by the blood against the walls of your arteries while your heart is resting between https://www.verywellhealth.com/systolic-and-diastolic-blood-pressure-1746075). During a basketball practice, Ricci's blood pressure is monitored. The coach found out that Ricci's blood pressure B varies sinusoidally with time t in seconds which is shown by the function B(t) = 20 sin (t) + 90. contractions. This is the period of ventricular relaxation. (Source: a. What is Ricci's systolic BP? (hint: Remember that sin x < 1) b. What is Ricci's diastolic BP? (hint: Remember that sin x 2-1) c.

6. In reading blood pressure (BP) there are always two numbers present. When your heart beats the first
number, the systole, indicates the pressure (measured in mm Hg) exerted by the blood along the walls of
your arteries. It is the peak blood pressure during active heart contractions. The second number, the
diastole, is the pressure exerted by the blood against the walls of your arteries while your heart is resting
between
contractions.
This
is
the
period
of
ventricular
relaxation.
