Exponential Growth/Decay
Plz help!!!

a) 82.

b) So a growth factor of 0.025

c) 2.5%.

d) f(5) = 93, which means that the population of the island on January 1st 2026 is of 93.

Step-by-step explanation:

Exponential equation of population growth:

The exponential equation for population growth has the following format:

In which x(0) is the initial value and r is the growth factor, as a decimal.

In this question:

In x years after 2021:

a)

This is f(0). So

So 82.

b)

We have to find r. So

So a growth factor of 0.025.

c)

Growth factor multiplied by 100%.

So 0.025*100% = 2.5%.

d)

f(5) = population in 5 years after January 1st 2021, that is, January 1st 2026.

f(5) = 93, which means that the population of the island on January 1st 2026 is of 93.
