Company A : 15h + 20
Company B : 5h + 40
when would company B be cheaper....
15h + 20 > 5h + 40 ...put the less then sign towards Company B, then solve
15h - 5h > 40 - 20
10h > 20
h > 20/10
h > 2
Company B would be cheaper when the hours (h) are greater then 2
I believe the answer is 3/14
not quite sure but thats my guess:)

ANSWER
Point if discontinuity:
{x}= \pm3
Zero of the function is
x = 0
EXPLANATION
The given rational function is:
f(x) = \frac{3x}{ {x}^{2} - 9}
This function is not continous when
{x}^{2} - 9 = 0
{x}= \pm \sqrt{9}
{x}= \pm3
The function is zero when,
3x = 0
x = 0
The amount of space not occupied by the rubber balls is given by:
Volume=(volume of the container)-(volume of the rubber balls)
volume of the container is given by:
V=πr²h
V=π*(5/2)²(20)
V=392.70 cm³
Volume of each ball is:
V=4/3πr³
V=4/3π(2.5)³=65.45 cm³
volume of four balls
65.45×4=261.8 cm³
The volume of the container that is not occupied by the balls will be:
V=392.70-261.8
V=130.9 cm³
