What is the answers to the question: Which rational expression is undefined when x = 0?

Rom4ik [11]

Answer:

option D

$\frac{4x-8}{-2x^2}$

Step-by-step explanation:

An expression is undefined when you get division by zero or in simple words when denominator is zero.

Now we will solve each expression one be one by plugging value of x = 0

$\frac{5(0)-4)}{3(0)-3}$

-4/-3 = 4/3

$\frac{6(0)}{9(0)-3}$

0/-3 = 0

$\frac{8x+6}{-x^2+1}$

$\frac{8(0)+6}{-0+1}$

6/1

$\frac{4x-8}{-2x^2}$

$\frac{4(0)-8}{-2(0)}$

<h3>-8/0</h3><h3>undefined</h3>

Rearrange the formula V = 1 3 πr2h for h. A) h = 3V πr2 B) h = V 3πr2 C) h = 3πr2 V D) h = πr2 3V

stiks02 [169]

Answer:

Option a) $h=\frac{3V}{\pi r^{2} }$

Step-by-step explanation:

The given formula seems to represent the volume of right circular cone. The correct formula is:

$V=\frac{1}{3} \pi r^{2} h$

We have to rearrange the formula for h. This means we have to move h on one side of the formula and all the other variables and constants on the other side of the equation. This can be done as shown below:

$V=\frac{1}{3} \pi r^{2} h\\\\3V=\pi r^{2} h\\\\h=\frac{3V}{\pi r^{2} }$
