A population of a city is 422,000 and increases by 12% each year. Use an exponential function to
find the population of the city after 8 years.

1,044,856

Step-by-step explanation:

To solve this problem, we can use the exponential growth formula which is:

A = total amount

P = original amount

r = growth rate (decimal)

t = years

Before we plug in the values, don't forget to change 12% to its decimal form.

12% -> -> 0.12

Now, lets plug in the values:

The population of the city after 8 years will be 1,044,856.

49%

step-by-step explanation:

when you realize that you dont know just realize i just took a test and im so smart

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
