In 2015, the population of a district was 10,600. With an annual growth rate of approximately 4%, what will the population be in 2040 according to the exponential growth function

Respuesta :

Answer:

[tex]19,090\ people[/tex]

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

[tex]y=a(1+r)^x[/tex]

where

y is the population

x is the time in years since year 2015

a is the initial value

r is the rate of change

we have

[tex]a=10,600\\r=4\%=4/100=0.04[/tex]

substitute

[tex]y=10,600(1+0.04)^x[/tex]

[tex]y=10,600(1.04)^x[/tex]

In the year 2040 the value of x is equal to

[tex]x=2040-2015=25\ years[/tex]

substitute

[tex]y=10,600(1.04)^{15} =19,090\ people[/tex]
