Answer:
1) 20%
2) Choice a.
Step-by-step explanation:
1) 
is the population initially.
is the population after a year.
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.
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 
is in years.
where is in months.
And 
When a number is next to a variable multiply so you problem really is 2(?)=60
I actually think its b cause it can't be d (thats obvious) yh........but i might be wrong
You have not provided the figures, therefore, I cannot provide an exact answer.
However, I can helps you with the steps.
One important thing to note is that when writing statements of congruency, the order of writing the letters is very important. This is because each side/angle in the first figure would be congruent to the corresponding side/angle in the second.
Therefore, all you have to do in the above question is write the congruent figures and determine the corresponding congruent sides/angles
Example:
If we are given that triangle ABC is congruent to triangle DEF
This means that:
AB = DE
BC = EF
AC = DF
angle A = angle D
angle B = angle E
angle C = angle F
Hope this helps :)
Y would equal -17! Good luck!
