Answer:
The initial populations of slugs is 40
Step-by-step explanation:
we have

This is a exponential function of the form

where
a is the initial value (value of f(x) when the value of x is equal to zero)
b is the base
r is the rate
b=(1+r)
In this problem we have

therefore
The initial populations of slugs is 40
<u><em>Verify</em></u>
For n=0
substitute in the function



The property that is shown is called the zero property.
To solve this problem you must apply the proccedure shown below:
1- You have that the laddder makes an angle of
with the ground and the top of the ladder reaches
.
2- Therefore, you have:

Where:

3-You must substitute values and solve for the lenght, as following:

Therefore, the answer is:
