What is the volume of the largest box that can be made from a square piece of cardboard with side lengths of 24 inches by cuttin
SVEN [57.7K]

You need to subtract the two cutouts on each side, so the side of the box would be 24- 2x. X would then become the height of the box once folded.

The volume is found by multiplying the 4 dimensions:

The volume becomes x(24-2x)^2

Now take the derivative of the formula to solve for x

Dv/dx= (24-2x)^2 + x^2(24-2x)*-2

= 24-2x(24-2x-4x)=0

X =12 or 4

24-2x = 24-2(4) = 24-8=16

Volume = 16 x 16 x 4 = 1024 cubic inches.

jeyben [28]

Answer:

She would pay $2.80 in sales tax.

Step-by-step explanation:

This question can be solved by proportions, using a rule of three.

Megan paid $2.52 in sales tax on an item that cost $36.00 before tax. How much in taxes for $40.00 before taxes?

$2.52 - $36.00

x - $40.00

Applying cross multiplication

36x = 40*2.52

x = \frac{40*2.52}{36}

x = 2.8

She would pay $2.80 in sales tax.

How do I find the slope if a line when y=4x+5
DaniilM [7]

Answer:

slope =4

Step-by-step explanation:

The slope intercept equation of a line is written in the form

y= mx+b

where m is the slope and b is the y intercept.

Since y =4x+5 is written is this form, we can see that 4 is the slope and 5 is the y intercept
