Answer:
1oz cost $0.39 which will be the unite rate
Step-by-step explanation:
We can solve this problem using discriminant.
x^2-4x-12's discriminant is
(-4)^2-4*-12=16+48 which is clearly larger than 0
This means that it crosses over the axes 2 times.
In case you don't know what discriminant is, its in equation ax^2+bx+c
the discriminant is b^2-4ac.
If its positive it has 2 crosses with x axis, if negative then 0 crosses, if 0 then 1 cross.
Hope this helped at least a little bit :D
To simplify, we need to find a number that can divide both the numerator and denominator equally. Can you find a number that will do this? I can't. So it is already simplified.
You would have to first times .03 times 10 then take that times 30,000 which should equal 900
Volume = (1/3) * base area * height
= 1/3 * 24 * 18
= 144 ft^3
