Answer:
1) 20%
2) Choice a.
Step-by-step explanation:

1)  is the population initially.
 is the population initially.
 is the population after a year.
 is the population after a year.
 represents the population increase factor.
 represents the population increase factor.
So let's evaluate that fraction:
 
 


0.2=20%
2) Let's figure out the population growth in terms of months instead of years.

We want t to represent months.
A full year is 12 months, in a full year we have that 
So we want a new P such that  since 12 months equals a year.
 since 12 months equals a year.
Let's look at the functions given to see which gives us this:
a) 
b) 
c) 
d) 
So a is the function we want.
Also another way to look at this:
 where
 where  is in years.
 is in years.
 where
 where  is in months.
 is in months.
And 
 
        
             
        
        
        
Its a because it should be 50 50 if u think whats 100/2 so that would be a simple event

Answer: 5/4
Step-by-step explanation:
 
        
             
        
        
        
(x^3 - y^3)(x^3 + y^3)
You can get this by factoring based on the a^2 - b^2 model
