a.
Answer to Problem 39PFA
Option A is true..
Explanation of Solution
Given information: The population of a small town, in thousands, represented by
This option is true because for year 2010 the value of t=0, putting this value in equation
This is in thousand, so the population is
Hence option A is true.

c.
Answer to Problem 39PFA
Option C is false.
Explanation of Solution
Given information: The population of a small town, in thousands, represented by
Hence option C is false.
d.
To state: whether the given statement is true or false.
d.
Answer to Problem 39PFA
Option D is true.
Explanation of Solution
Given information: The population of a small town, in thousands, represented by
For the year 2020 the value of t=10, putting this value in
Thus the population is nearly 3.169 in thousands
Which is clearly greater than 3100
e.
To state: whether the given statement is true or false.
e.
Answer to Problem 39PFA
Option E is false.
Explanation of Solution
Given information: The population of a small town, in thousands, represented by
For the year 2015 the value of t=5, putting this value in
