Answer:
The year is 2020.
Step-by-step explanation:
Let the number of years passed since 2010 to reach population more than 7000000 be 'x'.
Given:
Initial population is,
Growth rate is,
Final population is,
A population growth is an exponential growth and is modeled by the following function:
Taking log on both sides, we get:
Plug in all the given values and solve for 'x'.
So, for , the population is over 700,000. Therefore, from the tenth year after 2010, the population will be over 700,000.
Therefore, the tenth year after 2010 is 2020.

Step-by-step explanation:
the lat answer for the first picture correct just plug it in the hihger number for x and then try a larger number y decreases. The same answer for the second one 2
That is true, I don,t quite know how to explain it but I just did this problem yesterday.
