Jessica has been tracking the population of a town. the population was 8,230 last year and has been increasing by 1.25 times each year. how can jessica develop a function to model this?

f(x) = (8230 • 1.25)x where 1.25 is the rate of growth

f(x) = 8230(1.25)x where 1.25 is the rate of growth

f(x) = 1.25(8230)x where 8230 is the rate of growth

f(x) = 8230(x)1.25 where 8230 is the rate of growth

,  where 1.25 is the rate of growth .

Step-by-step explanation:

Given: Jessica has been tracking the population of a town.

The population was 8,230 last year and has been increasing by 1.25 times each year.

We know that the exponential growth function is given by :_

, where A is the initial amount and b is the multiplicative rate of change in x years.

If we consider the population last year as initial population, then we get the following function:-

,  where 1.25 is the rate of growth .

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
