The equation modeling the population growth of a small town is P(1) = 30000(1. 02)', where P represents the population 1 years from now.

What is the approximate population change that occurs between 2 years from now and 10 years from now?


A. 5,358

B. 6,570

C. 31,212

D. 35,150

E. 36,570

Respuesta :

For the given equation modelling , the population growth is defined as

P(t)=30000(1.02)^t , then approximate change in population which occurs between 2years and 10years is equal to 5,358.

As given in the question,

Given equation modelling is :

P(1)=30000(1.02)^1

Where P represents the population of 1 year from now.

From this we defined the standard equation modelling which is given by:

P(t)=30000(1.02)^t

Where 't' represents the time

Now when t = 2 years

P(2) = 30000(1.02)^2

      = 31,212

When t = 10years

P(10) = 30000(1.02)^10

        = 36,570

Approximate change in population between 2 years and 10 years is

= P(10) - P(2)

= 36,570 - 31,212

= 5,358

Therefore, for the given equation modelling , the population growth is defined as P(t)=30000(1.02)^t , then approximate change in population which occurs between 2years and 10years is equal to 5,358.
