A population P is initially 3000. Find an exponential model (growth or decay) for the population after t years if the population P decreases by 0.36 every 7 years. (Round your terms to three decimal places.)

Sagot :

The population model is an exponential decay because it decreases

The exponential model of the population is P = 3000(0.64^1/7)^t

How to determine the function?

The population decreases by 0.36 every 7 years.

This means that the function is an exponential decay.

An exponential decay function is represented as:

P = a((1 - r)^1/n)^t

Where:

  • a represents the initial value (3000)
  • r represents the rate (0.36)
  • n represents the number of years the population decreases (7)
  • P and t are the variables

So, we have:

P = 3000((1 - 0.36)^1/7)^t

Evaluate the difference

P = 3000(0.64^1/7)^t

Hence, the exponential model of the population is P = 3000(0.64^1/7)^t
