F is proportional to 1/x^2
distance = x
A reduction of 25 percent = 0.75x
Let’s put this in place of x
F = 1/(0.75x)^2
And simplify
F = 1/0.5625x^2
So you need to find the percentage increase from 1/x^2 to 1/0.5625x^2
So what does 1/x^2 multiply by to give 1/0.5625x^2
Written as an equation it is y/x^2 = 1/0.5625x^2
Multiply both sides by x^2
y = 1/0.5625
y = 1.778 (rounded to 3 decimal points)
So the decimal multiplier is 1.778 and so the percent increase is approximately 77.8%

Step-by-step explanation:
A) Discriminant = b² - 4ac = (12)² - 4(9)(4) = 144 - 144 = 0
B) Since the discriminant is 0, this means the equation only has one root.
C) The root is real in this case since the discriminant is not negative. Otherwise, we would have two imaginary roots if it were (remember that complex roots come in pairs)
The number of bags that they will need if each bag contains 500 cubic inches of confetti is 20,000
<h3>How to find the total volume ?</h3>
One bag contains 500 cubic inches of confetti.
Therefore,
1 bag = 500 inches³
The student need to fill 100 containers with the bag.
Each container can accomodates 100,000 cubic inches.
Therefore,
1 bag = 500 inches³
100,000inches³ = 1 container = 200 bags
Therefore,
100 containers will contain 20, 000 bags of confetti.
