Answer:
576cm^3
Step-by-step explanation:
To find volume, you multiply all three values together (6cm x 8cm=48cm^2 and 48cm^2 x 12cm=576cm^3)
To get the x-intercepts of the function, f(x) = 4x2 – 24x + 20
It has to be equated to zero and the values of x are the x-intercepts. So,
4x2 – 24x + 20 = 0
The resulting equation is a quadratic equation which can be solved by different methods. The solution is
x = 5, 1
The average therefore is:
(1+5/)2 = 3
I believe there is a picture of the situation missing, but we still have all the info necessary to solve.
We take the height, 5, and divide by the slope, 1/12, getting 60. This is the length of the ramp.

Carey earns c hourly
Anderson earns $6 hourly which is also 1+ c/2
So, 6=1+c/2
12=2+c
c=$10
Carey earns $10 hourly
