a.
Answer to Problem 14Q
Explanation of Solution
Given:
The elevation of low-elevation forest zone is above 1700 feet to 2500 feet.
Let x be the distance (in yards) that one can swim.
First requirement is to be able to swim at least 100 yards. This can be represented as the inequality:
The graph of this inequality is:
Let y be the time (in minutes) one can tread water.
Second requirement is, to be able to tread water for at least 5 minutes. This can be represented as the inequality:
The graph of this inequality is:
Let z be the length (in yards) one can swim under water without taking a breath.
Third requirement is, to be able to swim 10 yards or more under water without taking a breath. This can be represented as the inequality:
The graph of this inequality is:
b.
is the person who can swim 250 feet, tread water for 6 minutes and swim 35 under water without taking a breath satisfy the requirements of the course.
b.
Answer to Problem 14Q
No
Explanation of Solution
Given:
Three requirements of the course are:
First requirement is to be able to swim at least 100 yards.
Second requirement is, to be able to tread water for at least 5 minutes.
Third requirement is, to be able to swim 10 yards or more under water without taking a breath.
The requirements are given in yards, so first step is to convert the given data which is in feet to yards.
All the three requirements must be fulfilled to satisfy the requirements of the course but here it can be observed that the first requirement is not fulfilled which is to be able to swim at least 100 yards.
Hence, not satisfy the requirements of the course.
