2. The number of people in a town n years after the initial
count can be modeled by
the equation p(n)=25,000(0.8)n
where P is the population
and n is the number of years.

b. Is this town growing or
shrinking in population?
By what percentage?

a. What was the population
at the initial count?

c. Write an expression to
predict what the population
will be in 5 years

Step 1. Simply the equation
25,000*0.8*n
25,000* 0.8= 20,000n

Therefore if the value of n is any number below 1 (including) then the population will decrease

If the value of n is any number above 1 (not including 1 specifically above 1.25 to show increase because 1.25* 20,000= 25,000) then it will show an increase with 1 it will just be 20,000 that being less then 25,000.


-Population at the initial count: 25,000
-Is it increasing or decreasing: It depends on the value of n (explained above)
-By what percent: 80%
-Expression for 5 years: 25,000*0.8*5
- 25,000*0.8*5= 100,000 people

Skew lines(segments) are lines(segments) in 3 dimensions that do not intersect the given segment and are not parallel to it.  ae, bf, eg, and fh are your skew segments.  i hope that : )
