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 P(t) = 110 + 25 sin(152xt) where p(t) is the pressure (in mmHg) at time t, measured in minutes. (a) Find the amplitude, period, and frequency of p. (Round your answer for the period to four decimal places.) amplitude period frequency (b) Sketch a graph of p. 135- 25 110 76

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) = 110 + 25 sin(152xt)
where p(t) is the pressure (in mmHg) at time t, measured in minutes.
