Well, after doing all that math, here is what I came up with, I hope this helps! :) -1600x^2+28265x-21830
The y-intercept of the line is 40
Answer:
x = -1
Step-by-step explanation:
f(x) = g(x) when x = -1
Answer:
x=2
y=1.732
Step-by-step explanation:
we use the formulae.....
SOHCAHTOA
where..Cos 60°=1/x
cos60=0.5
0.5=1/1
<u>X</u><u>=</u><u>2</u>
0.8660=y/2
y= 1.732
I believe she will have 8 rolls of toilet paper left after one year.
She started with 36, then gave away 4, so then she would have 32 left for herself, then she used 2 every month so if you deduct 2 rolls every month for 12 months she would use 24 in one year. So 32-24 is 8.
