The situation can be modeled by a geometric sequence with an initial term of 284. The student population will be 104% of the prior year, so the common ratio is 1.04.
Let
P
P be the student population and
n
n be the number of years after 2013. Using the explicit formula for a geometric sequence we get
P

We can find the number of years since 2013 by subtracting.

We are looking for the population after 7 years. We can substitute 7 for

Answer:
13/12
Step-by-step explanation:
Answer:
Option 3 - 4 miles
Step-by-step explanation:
Given : In a city, the distance between the library and the police station is 3 miles less than twice the distance between the police station and the fire station. The distance between the library and the police station is 5 miles.
To find : How far apart are the police station and the fire station?
Solution :
Let the distance between police station and fire station be 'x'.
The distance between the library and the police station is 3 miles less than twice the distance between the police station and the fire station.
i.e.
The distance between the library and the police station is 5 miles.
i.e.
Therefore, The police and fire stations is 4 miles apart.
So, Option 3 is correct.
Answer:
w ≤ 13
Step-by-step explanation:
-2(w-4) ≥ -18
Divide both sides by -2:
w-4 ≤ -18/-2
Don't forget to turn the inequality around, because we divided by a negative number!! We had greater than, now we have less than.
w-4 ≤ 9
Add 4 to both sides:
<u>w ≤ 13</u>
