there's 2 parts of the question.Also , one of the last tutors did multiple questions and helped me with about most of my homework... can you help me with other questions than this too , thank you anyway though.

Part A:
In 2000, the population was 6.26 million.
In 2015, the population was 7 million.
The general form of the exponential function is given by
[tex]A=A_0e^{k\cdot t}[/tex]Where A0 is the initial population (6.26 million), k is the growth rate, and t is the number of years after 2000.
Let us first find the growth rate.
We are given that In 2015, the population was 7 million.
[tex]\begin{gathered} A=A_0e^{k\cdot t} \\ 7=6.26e^{k\cdot15} \\ \frac{7}{6.26}=e^{k\cdot15} \\ \ln (\frac{7}{6.26})=\ln (e^{k\cdot15}) \\ 0.1117=k\cdot15 \\ k=\frac{0.1117}{15} \\ k=0.0074 \\ k=0.01 \end{gathered}[/tex]So, the growth rate is 0.01 (rounded to 2 decimal places)
Therefore, the exponential growth model is
[tex]A=6.26e^{0.01t}[/tex]Part B:
We need to find the year for which the population will be 12 million.
Let us substitute A = 12 into the exponential growth function and solve for t
[tex]\begin{gathered} A=6.26e^{0.01t} \\ 12=6.26e^{0.01t} \\ \frac{12}{6.26}=e^{0.01t} \\ \ln (\frac{12}{6.26})=\ln (e^{0.01t}) \\ 0.6507=0.01t \\ \frac{0.6507}{0.01}=t \\ 65=t \\ t=65\: \text{years} \end{gathered}[/tex]Therefore, the country's population will be 12 million in the year 2065
