There is a range of blood pressure values that is considered healthy for people The function given below models the blood pressure, p, in millimetres of mercury, at time t. In seconds, of a person at rest: P (t) = -20 cos (5"#) + 100 The one statement about this person's blood pressure that is FALSE is: Every 10 seconds, this person's heart beats 12 times. The highest level of mercury for this person is 120 mL The lowest level of mercury for this person is 80 mL The heart rate of this person is 50 beats per minute. 2: Consider the following graph: 2 71/2 3 /2 Identify the equation represented by the graph and one of the solutions.
