Life science: maximum heart rate. A person exercising should not exceed a maximum heart rate, which depends on his or her gender, age, and resting heart rate. The following table shows data relating resting heart rate and maximum heart rate for a 20-yr-ald woman.
Resting Heart Rate, r (in beats per minute) | Maximum Heart Rate, M (in beats per minute) |
50 | 170 |
60 | 172 |
70 | 174 |
80 | 176 |
(Source: American Heart Association) |
a. Using the data points (50, 170) and (80, 176), find a linear function that fits the data.
b. Graph the
c. Use the function to predict the maximum heart rate of a woman whose resting heart rate is 67.
