Answer:
6
Step-by-step explanation:
The height of the debris after t seconds is given by the following equation:
![h(t) = 96t - 16t^{2}](https://tex.z-dn.net/?f=h%28t%29%20%3D%2096t%20-%2016t%5E%7B2%7D)
How many seconds will it take before the debris falls back to the ground?
This is t for which
![h(t) = 0](https://tex.z-dn.net/?f=h%28t%29%20%3D%200)
So
![96t - 16t^{2} = 0](https://tex.z-dn.net/?f=96t%20-%2016t%5E%7B2%7D%20%3D%200)
![16t(6 - t) = 0](https://tex.z-dn.net/?f=16t%286%20-%20t%29%20%3D%200)
or ![6 - t = 0](https://tex.z-dn.net/?f=6%20-%20t%20%3D%200)
or ![t = 6](https://tex.z-dn.net/?f=t%20%3D%206)
The debris start at the ground(t = 0), go up, and come back to the ground at t = 6s.
So it takes 6 seconds for the debris to fall back to the ground.

The expression for each salary plan if s is Fernando's total weekly sales, would be:
Expression A: S= 100+ 100(0.15y) y=Commission
Expression B: S= 150+ 150(0.10y)
What amount of weekly sales us plan B better than plan A, the answer would be:Plug in the numbers for Y and use the outcomes as the sales stay to increase. For example, start with 5 sales, then go to 10 then 15, and so on and so forth.
