A countrys population in 1990 was 145 million. In 1998 it was 151 million. Estimate the population in 2015 using the exponential growth formula. Round your answer to the nearest million

The population in 2015 will be 165 million.

Step-by-step explanation:

The exponential growth formula is given by:

Where:

a: is the initial population

r: is the rate of increase

Δt: is the time        

With the initial information we can find the rate:

Using logarithm:                                    

Using exponential:          

Now, we can find the estimated population in 2015:

Therefore, the population in 2015 will be 165 million.

I hope it helps you!

answer:   n ≤ -3 or n < -5

step-by-step explanation:

-5 + 2n ≥ -11

+5             +5

2n ≥ -6

2/2 ≤ -6/2

n ≤ -3

-6 - 10n > 44

+6           +6

-10n > 50

-10/-10 50/-10

n < -5
