Answer:
The estimate the population of the city in 2018 is 7 million.
Step-by-step explanation:
The population of city in 2012 = 6.27 million.
The exponential growth rate = 1.25%
Now, to find the estimate population of the city in 2018.
Number of years(n) = 2018-2012 = 6 years.
Rate (r) = 1.25%.
Population in 2012(P) = 6.27 million.
Population in 2018 = A.
Now, putting the formula to find the population:
[tex]A=P(1+\frac{r}{100})^{n}[/tex]
[tex]A=6.27(1+\frac{1.25}{100})^{6}[/tex]
Adding the fraction in bracket.
[tex]A=6.27(\frac{101.25}{100})^{6}[/tex]
[tex]A=6.27(1.0125)^{6}[/tex]
[tex]A=6.27\times 1.0509[/tex]
[tex]A=6.589[/tex]
After estimating the population it will be 7 million.
As estimating is round up the value because in hundredth place it is 8 and in tenth place it is 5.
Therefore, the estimate the population of the city in 2018 is 7 million.
