Well, that is the pressure
120+30 = 150 maximum
120 - 30 = 90 minimuum
look at that sin function
at t = 0, it is 30 sin 0 = 0
at t = 1, it is sin 2 pi = 0, a full period
so a period is one second
so there are 60 periods per minute
a) sub any time t to find the pressure at that moment.
b) the difference of time between a high pressure moment and the next high pressure moment would be one heartbeat.
so find the period of the function, which is 2pi/2pi = 1 sec
so there are 60 heartbeats per minute
The function P(t) = 120 + 30 sin (2πt) models the blood pressure (in millimeters of mercury) for a
person who has a blood pressure of 150/90 (which is high); t represents seconds. What is the period of
this function?
