By definition we have that the volume is given by:
</span>

<span> Where,
w: with
l: length
h: height
Substituting values we have:
</span>

<span> Rewriting:
</span>

<span> We look for the roots of the polynomial:
</span>

<span> We discard the negative roots because we want to find dimensions.
Thus, the dimensions are:

h = 18.6 inches</span>
Answer: A. Graph c nkkhgthjnvcf
Y = 7....when u have y = a number, this is a horizontal line with a slope of 0.
** now if u would have had x = 7, u would have had a vertical line with an undefined slope
Answer:
D
Step-by-step explanation:
Start by looking at the vertex form of a quadratic function, f(x) = a(x - h)^2 + k. The variables h and k are the values of the vertex. Plug those in to get f(x) = a(x - 4)^2 + 5. To find the variable a, plug in the point given for the x and y values. So, you get (21) = a((8) - 4)^2 + 5. Solve for a algebraically, and you get a = 1. Finally, plug everything in and simplify the equation. You should get that the quadratic function is f(x) = x^2 - 8x + 21. Hope this helps!
