Use the following information to answer the next question. Systolic and diastolic pressures mark the upper and lower limits in the changes in blood pressure that produce a pulse. The length of time between the peaks relates to the period of the pulse. Blood Pressure Variation 160 Systolic 120 Pressure (in millimetres of mercury) Pressure 80 Dlastbild 40 Pressure 0 0.8 1.6 24 3.2 Time (in seconds) Numerical Response 3. The amplitude is ab mm of mercury and the period is c.d seconds. Write the four digits for a, b, c, and d as your answer. Use the following information to answer the next question. Monique makes the following statements about a sine function of the form y = asin[b(x -c)]+ d: I. The values of a and d affect the range of the function. II. The values of c and d determine the horizontal and vertical translations, respectively. III. The value of b determines the number of cycles within the distance of 2x . IV. The values of a and b are vertical and horizontal stretches. 9 . Monique's correct statements are A. I, II, III, and IV B. I only C. I, II, and III only D.
