Answer:

Step-by-step explanation:

Given

square bottom area is 24\times 24\ in.^2

Suppose x in. is cut from each corner to make a open box with maximum volume

New base area is (24-x)\times (24-x) in.^2

Volume of box

V=(24-x)^2\times x

Differentiate V w.r.t x to get maximum volume

\frac{\mathrm{d} V}{\mathrm{d} x}=2\cdot (24-x)(-1)+1\cdot (24-x)^2

Put \frac{\mathrm{d} V}{\mathrm{d} x}=0

\left ( 24-x\right )\left [ -2x+24-x\right ]=0

\left ( 24-x\right )\left [ 24-3x\right ]=0

x=24,8

but x=24 is not possible therefore x=8 will yield maximum volume

V=(24-8)^2\cdot 8=2048\ in.^2

WARRIOR [948]

Answer:

The slope is <u>steeper</u> and the line is shifted <u>flatter</u>.

Step-by-step explanation:

I have provided a graph to help illustrate the relationship between these two lines, (The red line is line A which is y = 2x + 4, and the blue line is line B which is y = 4x + 9).

As you can see, the slope does determine the steepness of the lines. This means that line A's slope is going up 2 units and over to the right 1 unit, whereas line B's slope is going up 4 units and to the right 1.

Therefore, if line A is to transform into line B, then its slope will be steeper.

Hope this helps you :)

Also, P.S. I don't know if there are supposed to be more options, so I apologize if flatter does not belong in the second box.

Answer:

Step-by-step explanation:

let's place 9 in place of p and 4 in place of q. I will use a star in place of that symbol for the sake of my convenience having to look for it, apologies.

9 \star 4  = 9^2-4^2 = 81-16 = 65
