The area of the top of the rectangle table is 323 square feet. If the length of the table is19 feet what is the width of the tab

Anit [1.1K]

A=lw, right? So you would take what you know, 323 being a and 19 being l. 323=19w
Divide both sides by 19 leaving you with
323/19=w
17 feet=w

An open-top box with a square base is to have a volume of 4 cubic feet. Find the dimensions of the box (in ft) that can be made

Lemur [1.5K]

Answer:

The dimension of box= $2ft\times 2ft\times 1ft$

Step-by-step explanation:

We are given that

Volume of box=4 cubic feet

Let x be the side of square base and h be the height of box

Volume of box= $lbh=x^2h$

$4=x^2h$

$h=\frac{4}{x^2}$

Now, surface area of box,A= $x^2+4xh$

$A=x^2+4x(\frac{4}{x^2})=x^2+\frac{16}{x}$

$\frac{dA}{dx}=2x-\frac{16}{x^2}$

$\frac{dA}{dx}=0$

$2x-\frac{16}{x^2}=0$

$2x=\frac{16}{x^2}$

$x^3=8$

$x=2$

$\frac{d^2A}{dx^2}=2+\frac{32}{x^3}$

Substitute x=2

$\frac{d^2A}{dx^2}=2+\frac{32}{2^3}=2+4=6>0$

Hence, the area of box is minimum at x=2

Therefore, side of square base,x=2 ft

Height of box,h= $\frac{4}{2^2}=1 ft$

Hence, the dimension of box= $2ft\times 2ft\times 1ft$

Find the product. Write your answer in exponential form. 6^-6x6^-1

Tom [10]

So, the questions is 6^(-6) * 6^(-1).

Remember, whenever we are multiplying two numbers with the same base and with different exponents, we should always add the exponents and keeps the same base.

In this ,case it is, -6 and -1.

-6 + (-1) = -7

So the answer would be 6^(-7).

If you have any questions, please comment below.
