Suppose that Amanda's blood pressure can be modeled by the following function
{p(t)=80-15cos(76pi*t)
Amanda's blood pressure increases each time his heart beats, and it decreases as his heart rests in between beats. In this equation, p(t)is the blood pressure in mmHg (millimeters of mercury), and t is the time in minutes.
Find the following. If necessary round to the nearest hundredth.
Frequency of p: __ heartbeats per minute
Maximum blood pressure : __ mmHg
Time for one full cycle of p: __ minutes
as before,
p(t) = A + Bcos(kt)
has
period = 2π/k
frequency = 1/period
max = A + |B|
so just plug in your numbers
