1. The number of rabbits on an island is increasing exponentially. In Year 1 there are 50 rabbits.
In Year 5 there are 72 rabbits.
How many rabbits are there in Year 10?

There are approximately 114 rabbits in the year 10

Step-by-step explanation:

Exponential Growth

The natural growth of some magnitudes can be modeled by the equation:

Where P is the actual amount of the magnitude, Po is its initial amount, r is the growth rate and t is the time.

We are given two measurements of the population of rabbits on an island.

In year 1, there are 50 rabbits. This is the point (1,50)

In year 5, there are 72 rabbits. This is the point (5,72)

Substituting in the general model, we have:

Dividing [2] by [1]:

Solving for r:

Calculating:

r=0.095445

From [1], solve for Po:

The model can be written now as:

In year t=10, the population of rabbits is:

P = 113.6

There are approximately 114 rabbits in the year 10
