Inequalities and Absolute Value…………A project for Algebra Students
Where in the world would you ever encounter compound inequalities or
absolute value relationships? Hopefully after this project, you will readily
be able to answer that question.
Heart Rate during Exercise
Your target heart rate is a range, expressed as percentages of your
maximum heart rate. (Your maximum heart rate in beats per minutes is
based on how old you are -- it's 220 minus your age.) For most people, the
American College of Sports Medicine recommends a target heart rate while
exercising of 50% to 85% of your maximum heart rate.
For this project, you are to:
1. Calculate the recommended heart rate while exercising for a 10, 20,
30, 40, 50, and 60 year old.
2. Write each (6) of these as a compound inequality.
3. Graph each (6) of these compound inequalities.
4. Find the corresponding absolute value inequalities associated with
each compound inequality.
5. Write a summary of your findings.
6. Place your calculations, inequalities, graphs, absolute value inequalities,
and summary on a recyclable poster.
Your project will be graded as follows:
Topic
Possible Points
Calculations
All calculations for all 6 ages are
calculated correctly (6 @ 2pts ea =
12 pts)
Compound Inequalities for all 6 ages
are expressed correctly (6 @ 2pts
ea = 12 pts)
Graphs for all 6 ages are drawn
correctly (6 @ 2pts ea = 12 pts)
All absolute value inequalities for all
6 ages are expressed correctly (6
@ 2pts ea = 12 pts)
You have demonstrated an
understanding of why this
information is used and why it is
important.
