Application Exercises The maximum heart rate, in beats per minute, that yon should achieve during exercise is 220 minus your age: 220 - a. This algebraic expression gives maximum heart rate in terms of age, a. The following bar graph shows the target heart rate ranges for four types of exercise goals. The lower and upper limits of these ranges are fractions of the maximum heart rate, 220 - a . Exercises 129-130 are based on the information in the graph. If your exercise goal is to improve cardiovascular conditioning, the graph shows the following range for target heart rate, H , in beats per minute: Lower limit of range H = 7 10 ( 220 − a ) Upper limit of range H = 4 5 ( 220 − a ) . a. What is the lower limit of the heart rate range, in beats per minute, for a 20-year-old with this exercise goal? b. What is the upper limit of the heart rate range, in beats per minute, for a 20-year-old with this exercise goal?

Solution Summary: The author explains that the lower limit of heart rate during exercise for a 20-year-old is 140 beats per minute. The upper limit is 160.
The maximum heart rate, in beats per minute, that yon should achieve during exercise is 220 minus your age:
220 - a.
This algebraic expression gives maximum heart rate in terms of age, a.
The following bar graph shows the target heart rate ranges for four types of exercise goals. The lower and upper limits of these ranges are fractions of the maximum heart rate, 220 - a. Exercises 129-130 are based on the information in the graph.

In a table, list down 3 original examples of domain and range in real-life scenarios related
with your discipline (as a student or future professional).
Highlight the domain (yellow) and range (green) in the example
statements. All examples should be based on your own ideas and not from other sources of
information.
At sea level, the air pressure is 15 psi. As the vehicle goes underwater, the pressure
increases and as it goes up into the air, pressure decreases. The graph given below
shows the variation of pressure on the vehicle over time. Match the following letters
