QUESTION 6 The following graph will be used in the remaining questions of the quiz. 450 100 50 -0.2 0.2 0.4 0.6 0.8 12 1,4 16 1.8 Problems that involve a regularly repeating pattern or oscillation can be modeled by trigonometric functions. A common example is using a trigonometric function to model blood pressure. Blood pressure measures the cyclic variation of pressure on the arterial wall as a response to heart rhythm. The function below models the pressure cycle for one heartbeat. Pressure is measured in mm of mercury (Hg) and time is measured in seconds. P(t) = 25 sin STL+ + 115 The graph of P(t) is drawn above. Match the following features of the graph to their corresponding meanings. - Meaning of the amplitude A. 115 mmHg -Meaning of the period B. The duration of one heartbeat (in seconds) The blood pressure (systolic/diastolic) modeled by P(t) C. 1.25 sec - The heart rate in beats per minute modeled by P(t) D. The change in blood pressure from the mean - The period of P(t) E. 4/5 sec - vThe amplitude of P(t) F. 25 mmHg G. 115/25 H. 75 bpm 1. 140/90 J. The maximum blood pressure K. 48 bom
