Answer:
(a) 5894 thousand
(b) 6204 thousand
Step-by-step explanation:
Given:
The expression for population growth of the residents of Wisconsin is given as:
[tex]P(t)=5382(1.0057)^t[/tex]
For the year 2000, the time is, [tex]t=0[/tex]
(a) Population in 2016.
Difference in years from 2000 to 2016 = 2016 - 2000 = 16 years.
Therefore, the time 't' for 2016 is equal to 16 years.
Now, plug in 16 for 't' in the above expression and solve for population 'P'. This gives,
[tex]P(t)=5382(1.0057)^t[/tex]
[tex]P(16)=5382(1.0057)^{16}\\\\P(16)=5894.4\approx 5894\ thousands[/tex]
Therefore, the estimated population of the residents in 2016 is 5894 thousand.
(b) Population in 2025.
Difference in years from 2000 to 2025 = 2025 - 2000 = 25 years.
Therefore, the time 't' for 2025 is equal to 25 years.
Now, plug in 25 for 't' in the above expression and solve for population 'P'. This gives,
[tex]P(t)=5382(1.0057)^t[/tex]
[tex]P(25)=5382(1.0057)^{25}\\\\P(25)=6203.8\approx 6204\ thousands[/tex]
Therefore, the estimated population of the residents in 2016 is 6204 thousand.
