It's a pentagonal pyramid.
Answer:
After how many years is the fish population 100?
x=3.97 years
Step-by-step explanation:
The fish population increases by a factor of 1.5 each year. We have the equation that represents this situation

Where x represents the number of years elapsed f(x) represents the amount of fish.
Given this situation, the following question could be posed
After how many years is the fish population 100?
So we do
and solve for the variable x

Observe the solution in the attached graph
Answer: 9x^2-2x-1
Step-by-step explanation: hope this helps!
Gather your data
Organize it in numerical order
Create a horizontal line on a graph that represents your data
The answer is 45 miles per hour. First, there are 60 minutes in one hour. So you divide 60 by 20, which equals 3. Knowing that, you multiply 15 by 3, which equals 45.
