a.
To create: A scatter plot of the data and graph the model in the same viewing window.
a.
Answer to Problem 44E
The model is a good fit for the actual data values especially on the last half part.
Explanation of Solution
Given information: The table shows the numbers N(in thousands) of U.S. military.
receiving retired pay for the years 2000 through 2012
A model for the data is
Where t represents the year with t=0 corresponding to 2000.
Calculation:
The model is a good fit for the actual data values especially on the last half part.
b.
To predict: The number of military retirees in 2019, using model.
b.
Answer to Problem 44E
Explanation of Solution
Given information: The table shows the numbers N(in thousands) of U.S. military.
receiving retired pay for the years 2000 through 2012
A model for the data is
Where t represents the year with t=0 corresponding to 2000.
Calculation:
c.
The limit of the function as t approaches infinity and the limit in the context of the problem.
c.
Answer to Problem 44E
Explanation of Solution
Given information: The table shows the numbers N(in thousands) of U.S. military.
receiving retired pay for the years 2000 through 2012
A model for the data is
Where t represents the year with t=0 corresponding to 2000.
Calculation:
Over time ,the number of U.S. military retirees approach 0.This limit is not realistic given that it is necessary to have military in every country.
