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(164rt) 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. AN P 135 110 85 P 135 M 82 110 82 AN (c) If a person is exercising, his or her heart beats faster. How does this affect the period and frequency of p? O The period decreases and the frequency decreases. 85 v O The period decreases and the frequency increases. O The period increases and the frequency increases. O The period increases and the frequency decreases. O It does not affect the period and frequency; it only affects the heart rate.

what it means to have a change in amplitude and a change in period.

A ferris wheel is 27 meters in diameter and completes 1 full revolution in 8 minutes. A ferris wheel is 27 meters in diameter and boarded from a platform that is 1 meter above the ground. The 6 o'clock position on the Ferris Wheel is level with the loading platform. Th wheel conpletes 1 full revolution in 8 minutes. The function h(t) gives a person's height in meters above the ground t minutes after the wheel begins to turn. a. Find the amplitude, midline, and period of h(t). Enter exact answers b. Assume that a person has just boarded Ferris wheel from the platform and that the Ferris Wheel starts spinning at time t=0. Find a formula for the height function h(t). Hints: •What is the value of h(0) • Is this the maximum value of h(t), the minimum value of h(t), or a value between the two? • The function sin(t) has a value between its maximum and minimum at t=0, so can h(t) be a straight sine function? • The function cos(t) has its maximum at t=0, so can h(t) be a straight cosine…

A ferris wheel is 15 meters in diameter and boarded from a platform that is 5 meters above the ground. The six o'clock position on the ferris wheel is level with the loading platform. The wheel completes 1 full revolution in 4 minutes. The function h = f(t) gives your height in meters above the ground t minutes after the wheel begins to turn. Amplitude -------- Minutes  Midline ------ Minutes  period ----- minutes  How high are you off of the ground after 2 minutes --- meters  answers are  7.5 12.5 4 20  please explain neatly , thank you !
