Answer:

f=1/x^2-81

Step-by-step explanation:

Step 1: Multiply both sides by x^2-81.

fx3−81fx=x

Step 2: Factor out variable f.

f(x3−81x)=x

Step 3: Divide both sides by x^3-81x.

f(x3−81x)

x3−81x =x x3−81x f= 1 x2−81

The length of a rectangle is twice it’s with the perimeter of a rectangle is 126 feet.
madreJ [45]

Answer:

Length = 42 feet

Width = 21 feet

Step-by-step explanation:

Let the length and width be represented by L and W

L = 2W

Perimeter (P) = 126 feet

2(L + W) = 126

L + W = 126/2 = 63

2W + W = 63

3W = 63

W = 63/3 = 21 feet

L = 2W = 2 × 21 feet = 42 feet

Find the volume h=12cm r=5cm
Goshia [24]

If this was a cone, the volume would be 314.16.

  • You would just put in the radius and height in the cone volume formula which is πr²h 1/3

If this is a cylinder then the volume would be 942.48

  • Put in the radius and height in the cylinder volume formula which is πr²h

PLease help me ,really need help with explanation​
mylen [45]

a)

Check the picture below.

b)

volume wise, we know the smaller pyramid is 1/8 th of the whole pyramid, so the volume of the whole pyramid must be 8/8 th.

Now, if we take off 1/8 th of the volume of whole pyramid, what the whole pyramid is left with is 7/8 th of its total volume, and that 7/8 th is the truncated part, because the 1/8 we chopped off from it, is the volume of the tiny pyramid atop.

Now, what's the ratio of the tiny pyramid to the truncated bottom?

\stackrel{\textit{\Large Volumes}}{\cfrac{\textit{small pyramid}}{\textit{frustum}}\implies \cfrac{~~\frac{1}{8}whole ~~}{\frac{7}{8}whole}}\implies \cfrac{~~\frac{1}{8} ~~}{\frac{7}{8}}\implies \cfrac{1}{8}\cdot \cfrac{8}{7}\implies \cfrac{1}{7}
