Answer:
$11.08 to the nearest penny
Step-by-step explanation:
So I do it like
10.26 is 100 percent
We’re adding 8 percent so technically multiplying by 108
SO 10.26*108 is 11.08 to the nearest penny
It so much easier, easy 1 step
To find the zeroes you make the function equal to zero and then solve.
![0=x^3-2x^2-3x](https://tex.z-dn.net/?f=0%3Dx%5E3-2x%5E2-3x)
Then factor out the x to get a quadratic inside the parentheses.
![0=x(x^2-2x-3)](https://tex.z-dn.net/?f=0%3Dx%28x%5E2-2x-3%29)
Factor the inside quadratic formula.
![x(x^2-2x-3)=x((x-3)(x+1))](https://tex.z-dn.net/?f=x%28x%5E2-2x-3%29%3Dx%28%28x-3%29%28x%2B1%29%29)
Lastly, use the zero product property to solve.
![x*(x-3)*(x+1)=0](https://tex.z-dn.net/?f=x%2A%28x-3%29%2A%28x%2B1%29%3D0%20)
