Each time your heart beats, your blood pressure increases, then decreases as the heart rests between beats. A certain person's blood pressure is modeled by the function $p ( t ) = 120 + 25 \sin ( 150 \pi t )$ , where $p ( t )$ is the pressure in mmHg, at time t measured in minutes.
(a) Find the amplitude, average pressure between beats, the maximum and minimum blood pressure, period, and frequency of p.
(b) Sketch the graph of p.

The Answer of Each time your heart beats, your blood pressure increases, then decreases as the heart rests between beats. A certain person's blood pressure is modeled by the function $p ( t ) = 120 + 25 \sin ( 150 \pi t )$ , where $p ( t )$ is the pressure in mmHg, at time t measured in minutes. 
(a) Find the amplitude, average pressure between beats, the maximum and minimum blood pressure, period, and frequency of p.
(b) Sketch the graph of p.

Each Time Your Heart Beats, Your Blood Pressure Increases, Then p(t)=120+25sin⁡(150πt)p ( t ) = 120 + 25 \sin ( 150 \pi t )p(t)=120+25sin(150πt)

Each Time Your Heart Beats, Your Blood Pressure Increases, Then $p ( t ) = 120 + 25 \sin ( 150 \pi t )$
