Concept explainers
(a)
To find: the period of the model.
(a)
Answer to Problem 94E
Period of the model is 365 days.
Same answer is expected as because there are 365 days in a year.
Explanation of Solution
Given information:
The daily consumption
Where
Calculation:
The period of the model is,
Yes, we expected the same answer as because there are 365 days in a year.
(b)
To find: the average daily fuel consumption, to find the model did use.
(b)
Answer to Problem 94E
30.3 gal
Explanation of Solution
Calculation:
The average daily fuel consumption is 30.3 gal
We used the constant term for it.
(c)
To find: a graph of the model, and to approximate the time of the year when consumption exceeds 40 gallons per day.
(c)
Answer to Problem 94E
The time of the year when the fuel consumption exceeds 40 gals per day is
Explanation of Solution
Let us plot the graph for the given model,
Hence, the time of the year when the fuel consumption exceeds 40 gals per day is
