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) = 115+25 sin(160xt) where p(t) is the pressure in mmHg (millimeters of mercury), at time t measured in minutes. Find the amplitude and period of p(t). O 1 amplitude = 25; period = 80 O amplitude 115; period = 80 O amplitude = 115; period NO 80 amplitude = 25; period BU 80
