a.
What is the period of each function?
a.
Answer to Problem 83E
Explanation of Solution
Given information:
The normal monthly high temperatures H (in degrees Fahrenheit) in Erie, Pennsylvania, are approximated by
What is the period of each function?
Calculation:
Period
Period
Hence, the Period of each function=
b.
What is the maximum and least temperature?
b.
Answer to Problem 83E
In July that means in summer difference is max. Is least in fall season.
Explanation of Solution
Given information:
The normal monthly high temperatures H (in degrees Fahrenheit) in Erie, Pennsylvania, are approximated by
During what part of the year is the difference between the normal high and normal low temperatures greatest? When is it least?
Calculation:
In July that means in summer difference is max. Is least in fall season.
Hence the difference is max. In July and least in fall season.
c.
Approximate the lag time of the temperatures relative to the position of the sun.
c.
Answer to Problem 83E
Graph shows warmest temperature in July starting lag time of
Explanation of Solution
Given information:
The normal monthly high temperatures H (in degrees Fahrenheit) in Erie, Pennsylvania, are approximated by
The sun is northernmost in the sky around June 21, but the graph shows the warmest temperatures at a later date. Approximate the lag time of the temperatures relative to the position of the sun.
Calculation:
Graph shows warmest temperature in July starting lag time of
Hence , the warmest temperature in july starting lag time of
