Answer:

a) P(21)=40

b) P max = 60

c) P min = 20

Explanation:

Function Modeling

The blood pressure P is modeled with the equation

[tex]P=20sin(2\pi t)+40[/tex]

Where t is in seconds.

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

[tex]P(21)=20sin(2\pi \cdot 21)+40[/tex]

[tex]P(21)=40[/tex]

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

[tex]P_{max}=20\cdot 1+40=60[/tex]

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

[tex]P_{min}=20\cdot -1+40=20[/tex]
