We have been given that the number of students enrolled at a college is 18,000 and grows 4% each year. We are asked to find number of students after 22 years.
We will use exponential growth function to solve our given problem.
We know that an exponential growth function is in form 
, where
y = Final value,
a = Initial value,
r = Growth rate in decimal form,
x = Time
To find number of students after 22 years, we will substitute 
in our function.
Therefore, there will be approximately 42,659 students after 22 years.
7.5 mins = 0.125 hr
6hr/ 0.125hr = 48 glass
48x500g = 24 000 grams = 24 Kg
24 (P5) = P 120

Answer:
f(-4) = 5
Step-by-step explanation:
Explanation of
_
| 5, x < -3
f(x) | 2x² - 4, -3 ≤ x ≤ 4
| 1 - 6x , x > 4
_
When the x in f(x) is less than -3 than f(x) = 5
When the x in f(x) is greater than -3 but less than 4 then f(x) = 2x² - 4
When the x in f(x) is greater than 4 than f(x) = 1 - 6x
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Now that we know this lets look back at the question.
We want to find f(-4).
Looking at the piece wise function we see that f(-4) follow x < -3 as "x" or -4 is less than -3. When x is less than -3, f(x) = 5, hence f(-4) = 5
$57.75 because 14 divided by .25 is 56 and then plus the first mile is 57.75
Its easy all you do is add the time given or subtract it
