Question 1165349
.
A person’s resting blood pressure is 116 over 88. This means that the blood pressure oscillates 
between a maximum of 116 and a minimum of 88. The person’s resting heart rate is 60 beats per minute. 
Let P represent the blood pressure and t represent the time in seconds. 
Write the equation for the blood pressure P as a function of time t seconds.
~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Mid-line is  a = {{{(116+88)/2}}} = 102.


The amplitude is  A = {{{(116-88)/2}}} = 14.


The period is  T = {{{60/60}}} = 1 second.


The cosine function is

    P(t) = {{{a + A*cos(2*pi*(t/T))}}} = 102 + 14*cos(6.28*t),


where t is the time in seconds.

Solved.
