It compiles the number of heartbeats after t minutes. When the data in the table are graphed, the slope of the tangent line represents the heart rate in beats per minute t (min) 36 38 40 42 44 Heartbeats 2537 2672 2808 2940 3077 The monitor estimates this value by calculating the slope of a secant line. Use the data to estimate the patient's heart rate after 42 minutes using the secant line between the points with the given values of t. (Round your answers to one decimal place.) (a) t = 36 and t = 42 (b) t = 38 and t = 42 (c) t = 40 and t = 42 (d) t = 42 and t = 44 Submit Answer MY NOTES 3. [-/6 Points] DETAILS SCALCCC4 2. 1.006.MI.
