By cutting away identical squares from each corner of a rectangular piece of cardboard and folding up the resulting flaps, an op

sp2606 [1]

Answer:

The maximum volume is: 11.52 *10.52*2.74 = 332.06 $in^{3}$

Step-by-step explanation:

Let x is the side of the square in inches.(x >0)

The volume of the resulting box when the flaps are folded up can be expressed as:

V = x (17 -2x)(16-2x)

= (17x -2 $x^{2}$ )(16-2x)

= $4x^{3}$ - 66 $x^{2}$ + 272x

To find the value of x which yields the maximum of volume (V), take the first derivative of this equation and set it equal to zero.

$\frac{dV}{dx}$ = 12 $x^{2}$ - 66x + 272

Solve 12 $x^{2}$ - 132x + 272 = 0

<=> x = 2.74

The dimensions of the box are:

Length: (17 -2x) = (17 -2*2.74) = 11.52

Width: (16-2x) = (16-2*2.74) = 10.52

High: x = 2.74

So the maximum volume is: 11.52 *10.52*2.74 = 332.06 $in^{3}$

Match each polynomial expression to its additive inverse

zvonat [6]

Answer:

(1, 2, 3, 4) matches (A, C, B, D)

Step-by-step explanation:

The additive inverse of a term is formed by changing the sign. The additive inverse of the polynomial is formed by changing the sign of every term.

If we call the expressions on the left (top-to-bottom) 1, 2, 3, 4, and those on the right A, B, C, D, then the match-up <em>in this presentation of the question</em> is ...

1 - A

2 - C

3 - B

4 - D

_____

YMMV if the expressions are mixed differently
