The equation P=20sin(2πt)+40 models blood pressure, P, where t represents time in seconds. Find the blood pressure after 21 seconds. Also, give the maximum and minimum blood pressures.

a) P(21)=40

b) P max = 60

c) P min = 20

Explanation:

Function Modeling

The blood pressure P is modeled with the equation

Where t is in seconds.

a) We'll find the pressure when t=21 seconds

b) The maximum value will occur when the sine function has a value of 1

c) The minimum pressure will occur when the sine function is at minimum (-1)
