I'm going to take a guess regarding what you meant to type in:

<span>3x-9 X +6x+5
E(x)= ------- × -------------
2 2
X -9 X +5x+6

3(x+3) 6x+5
becomes E(x) = ----------- * ------------
x-9 5x+6

This cannot be reduced.

Try again to share this problem. Thank you.

A sphere and a cylinder have the same radius and height. The volume of the cylinder is 21 meters cubed. A sphere with height h a

Elodia [21]

We have been given that a sphere and a cylinder have the same radius and height. The volume of the cylinder is 21 meters cubed. We are asked to find the volume of the sphere.

We know that height of sphere is equal to its radius. This means that $r=h$ .

$\text{Volume of sphere}=\frac{4}{3}\pi r^3$

$\text{Volume of cylinder}=\pi r^2 h$

Using $r=h$ , we will get:

$\text{Volume of cylinder}=\pi r^2\cdot r$

$\text{Volume of cylinder}=\pi r^3$

Upon comparing volume of sphere and volume of cylinder, we can see that volume of sphere is $\frac{4}{3}$ times volume of cylinder.

$\pi r^3=21$

$\frac{4}{3}\pi r^3=\frac{4}{3}\cdot 21$

$\frac{4}{3}\pi r^3=4\cdot 7$

$\frac{4}{3}\pi r^3=28$

Therefore, the volume of the sphere would be 28 cubic meters.

Parker is laying pavers to build a patio in his backyard. Each square paver measures 2 feet on each side. He would like the pati

MatroZZZ [7]

Answer:

32 pavers

Step-by-step explanation:

step 1

Find out the area of one square paver

The area of a square is

$A=s^{2}$

where

s is the length side of the square

we have

$s=2\ ft$

substitute

$A=2^{2}\\A=4\ ft^{2}$

step 2

Find out the area of the rectangular patio

we know that

The area of a rectangle is

$A=LW$

we have

$L=16\ ft\\W=8\ ft$

substitute

$A=(16)(8)\\A=128\ ft^2$

step 3

Find out the number of pavers needed to build the patio

Divide the area of the rectangular patio by the area of one paver

$128\ ft^2/4\ ft^{2}=32\ pavers$

Answer:

inconsistent

Step-by-step explanation:

The two lines are parallel which means they will never intersect. This means they have no solution. When there is no solution they are inconsistent.

Coincident- same line - infinite solutions

Inconsistent - parallel lines - no solutions

Consistent and independent - 1 solutions

Anni [7]

Answer:

$y\tan{x°}$

Step-by-step explanation:

well, by using definition of tan of an angle

let the distance between Earth and shooting star is $d$ .

since $\frac{d}{y}=\tan{x°}$ ,

then $d=y\tan{x°}$
