The equation P = 20 sin(2𝜋t) + 110 models the blood pressure, P, where t represents time in seconds.

Question

Find the blood pressure after 11 seconds. 

What is the maximum blood pressure? 

What is the minimum blood pressure? 

Answer 1

P = 20 sin(2𝜋t) + 110

= 20sin(22π)+110

= 128.685

Answer 2

the midline is at 110(vertical shift) and the amplitude is 20 so value is 110 +/-20

Max is 130 and min is 90
