In 2000, the population of a state was 6.8 million people and was growing at a rate of about 0.32% per year. at this growth rate, the function f (x) = 6.8(1.0032)x gives the population, in millions x years after 2000. using this model, find the year when the population reaches 7 million people. round your answer to the nearest whole number. the population will reach approximately 7 million people during the year.

9 years. Rounded.

Step-by-step explanation:

Givens

f(x) = 7 (the amount you would like to see reached which is 7 million).

6.8 = Current population.

1.0032 = the base increase.

x = the number of years

Equation

f(x) = Current* Base^x

Solution

7 = 6.8 * (1.0032)^x                 Divide both sides by 6.8

7/6.8 = 6.8* (1.0032)^x/6.8     Do the division

1.0294 = (1.0032)^x                 Take the log of both sides. (You could use ln)

log(1.0294) = x * log(1.0032)    Calculate.

0.0126 = x * .001387                Divide by 0.001387

0.0126/0.001387 = x                Divide

9.08 years. = x                          Answer
