A cylindrical tube has a radius of 4 inches and a height of 14 inches could some one help me find the volume

pickupchik [31]

The volume of the cylinder is the area of the base (a circle) times the height (you can immagine taking a disk, the base, and translate it along the height to "fill" the cylinder).
So you have:
$V=area.circle*height= \pi r^{2}*h = \pi 4^{2} *14=703.4 in^{2}$

Is the following expression true or false? Show your work.

Paul [167]

Answer: True

Solution:

Rearrange the equation to the LHS:

[x^2 + 8x + 16] · [x^2 – 8x + 16] - (x^2 – 16)^2 = 0

Factoring x^2+8x+16

x^2 - 4x - 4x - 16

= (x-4) • (x-4)

= = (x+4)2

So now we have an equation

(x + 4)^2 • (x - 4)^2 - (x^2 - 16)^2 = 0

Step 2: Evaluate the following:

(x+4)2 = x^2+8x+16

(x-4)2 = x^2-8x+16

(x^2-16)2 = x^4-32x^2+256

(x^2+8x+16) (x^2-8x+16 ) - (x^4-32x^2+256 )

0 = 0

Hence True

What is the simplified form of the square root of 80?

djyliett [7]

$\sqrt{80} = \sqrt{2 * 2* 2* 2* 5} = \sqrt{2^{2}*2^{2}*5} = 2*2* \sqrt{5} = 4 \sqrt{5}$
Hope this helps.
