Answer:

290

Step-by-step explanation:

This may not be right but I used the equation f(x) = 3(10)^{2} - 10.

f(x) = 3(10)^2 - 10\\\\f(x) = 3(100) - 10 \\\\f(x) = 300 - 10\\\\f(x) = 290

The population of a small industrial town was 12 910 in 2000. Each year, the population
balandron [24]

The population in the year 2020 is 4628

<h3>How to determine the population?</h3>

The given parameters are:

Initial, a = 12910

Rate, r = 5%

Since the population decreases, then we make use of an exponential decay function.

This is represented as:

f(n) = a * (1 - r)^n

So, we have:

f(n) = 12910 * (1 - 5%)^n

Evaluate the difference

f(n) = 12910 * 0.95^n

2020 is 20 years from 2000.

So, we have:

f(20) = 12910 * 0.95^20

Evaluate

f(20) = 4628

Hence, the population in the year 2020 is 4628
