Answer:
a 1 = 10
a 2 = 10 * 1/5 = 2
a 3 = 2 * 1/5 = 2/5
a 4 = 2/5 * 1/5 = 2/25
a 5 = 2/25 * 1/5 = 2/125
S 5 = a 1 + a 2 + a 3 +a 4 + a 5= 10 + 2 + 2/5 + 2/25 + 2/125 =
= 1250/125 + 250/125 + 50/125 + 10/125 + 2/125 = <u> 1562 / 125</u>
Answer:
y = 1.5x
Step-by-step explanation:
What you would do is divide all of the minutes by the amount of pages to find how long for each rate for one page. (ex. 18/12, michael reads 1 page in 1.5 minutes. 12/8, michael reads 1 page in 1.5 minutes. 30/20, michael reads one page in 1.5 minutes) Therefore, yes it is proportional, and the equation is y=1.5x (there is no y intercept)
Answer:
a. 
b. 17 years
c. The amount that is currently charged by the college you attend is much higher than the amount charged in two-year college in the present year.
Step-by-step explanation:
a.

Here, x is a the number of years after 2000 and f(x) is the total cost.
To approximate the yearly cost of attending a two-year college in the year 2016, find
.

b.
To predict in what year the yearly cost of tuition and required fees will exceed $3200, solve 

So,
x is approximately equal to 17 years.
c.
The present year is 2020.
To approximate the yearly cost of attending a two-year college in the present year, find 

The amount that is currently charged by the college you attend is much higher than the amount charged in two-year college in the present year.
