a.
To determine the year in which Germany had the greatest population, and the population.
a.

Answer to Problem 70E
Germany will had its greatest population in the year 2003.
The population of Germany in 2003 was
Explanation of Solution
Given information:
The population
Formula used:
The following formula is used:
Calculation :
In the given function,
The function has a maximum value when
The value of
The population is greatest for
Hence, Germany will had its greatest population in the year 2003.
The population in 2003 can be calculated by:
Hence, the population of Germany in 2003 was
b.
To determine the population of Germany in the year 2075.
b.

Answer to Problem 70E
According to the model the population of Germany in the year 2075 will be
No, this result is not reasonable.
Explanation of Solution
Given information:
The population
Calculation :
For 2075,
The population in the year 2075 can be calculated by:
Hence, according to the model the population of Germany in the year 2075 will be
No, this result is not reasonable, because the population has decreased by a very large amount.
