Question: A cardiac monitor is used to measure


A cardiac monitor is used to measure the heart rate of a patient after surgery. 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.




A cardiac monitor is used to measure the heart rate of a -1


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.
a. t = 36 and t = 42
b. t = 38 and t = 42
c. t = 40 and t = 42
d. t = 42 and t = 44
What are your conclusions?
