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]
