A person’s blood pressure, 𝑃, varies with the cycle of their heartbeat. The pressure (in units mmHg) at time 𝑡 seconds for a particular person may be modeled by the function: 𝑷(𝒕) = 20cos(2𝜋t) + 𝟏00 mmHg, 𝑡 ≥ 0 . According to this model, which of the following statements is TRUE? (Hint: Think of this problem in terms of transformations of a graph. In fact, actually graphing it will help you answer the question!)
(a) The maximum pressure is 100 mmHg.
(b) The pressure goes through one complete cycle in 2 seconds.
(c) The amplitude of the pressure function is 120 mmHg.
(d) The pressure will reach a maximum value at time 𝑡 = 1 second.
(e) Both statements (b) and (d) are accurate.
