\frac{3x^{2}+6x}{x^{2}-2x-8} = \frac{3x(x+2)}{(x-4)(x+2)}= \frac{3x}{x-4} 
\\ \\ \frac{3x}{x-4} , x \neq 4

x \neq -2

Find the arc length with the given information.<br> central angle = n/4, radius=3
BabaBlast [244]

Answer:

\frac{3\pi }{4}

Step-by-step explanation:

Arc length is the product of central angle(in radians) and radius.

i.e.

arc length=radius *central angle(in radians)

s=r*theta\\s=3*\frac{\pi }{4}\\ s=\frac{3\pi }{4}

A spherical ball with a volume of 2,304π in.3 is packaged in a box that is in the shape of a cube. The edge length of the box is
Nutka1998 [239]

Answer:

Therefore the volume of the box is 13824 in³

Step-by-step explanation:

Given:

A spherical ball with is packaged in a box that is in the shape of a cube.

Volume of ball = 2304π in³.

Let 'r' be the radius of sphere

To Find:

Volume of Cube = ?

Solution:

Volume of sphere is given by

\textrm{Volume of sphere}=\dfrac{4}{3}\pi r^{3}

Substituting the values we get

2304\pi=\dfrac{4}{3}\pi r^{3}\\\\\therefore r^{3}=1728\\\\Cube\ Rooting\\\\r=12\ in

Now we know that diameter is given by

diameter=2\times r=2\times 12=24\ in

it is given that,

The edge length of the box is equal to the diameter of the ball.

Therefore the length of cube = 24 in

Now the volume of the cube is given by

\textrm{Volume of cube}=(edge)^{3}

substituting the values we get

\textrm{Volume of cube}=(24)^{3}=13824\ in^{3}

Therefore the volume of the box is 13824 in³
