Answer:

+5 or -5.

Step-by-step explanation:

Given equation,

5x-10/x^2-25

When you divide something with zero, it becomes undefined. So, to be undefined, x will have to be that value which makes the divisor zero.

Now, x^2-25= 0

Or, x^2= 25

Or, x= +5,-5.

So, for the value +5 and -5, the divisor becomes zero and makes the whole equation undefined.

Four plumbers estimated the length of the radius of a cylindrical pipe. The estimates made by

o-na [289]

Answer:

B. $\frac{\sqrt{3}}{11}, \frac{\pi}{24}, \frac{3}{25}, \frac{9}{100}$

Step-by-step explanation:

The question is not properly presented. See attachment for proper presentation of question

From the attachment, we have that:

$W = \frac{3}{25}$

$X = \frac{\sqrt{3}}{11}$

$Y = \frac{9}{100}$

$Z = \frac{\pi}{24}$

Required

Order from greatest to least

First, we need to simplify each of the given expression (in decimals)

$W = \frac{3}{25}$

$W = 0.12$

$X = \frac{\sqrt{3}}{11}$

Take square root of 3

$X = \frac{1.73205080757}{11}$

$X = 0.15745916432$

$X = 0.16$ --- approximated

$Y = \frac{9}{100}$

$Y = 0.09$

$Z = \frac{\pi}{24}$

Take π as 3.14

$Z = \frac{3.14}{24}$

$Z = 0.13083333333$

$Z = 0.13$ --- approximated

List out the results, we have:

$W = 0.12$ $X = 0.16$ $Y = 0.09$ $Z = 0.13$

Order from greatest to least, we have:

$X = 0.16$ $Z = 0.13$ $W = 0.12$ $Y = 0.09$

Hence, the order of arrangement is:

$X = \frac{\sqrt{3}}{11}$ $Z = \frac{\pi}{24}$ $W = \frac{3}{25}$ $Y = \frac{9}{100}$

i.e.

$\frac{\sqrt{3}}{11}, \frac{\pi}{24}, \frac{3}{25}, \frac{9}{100}$

5 less the quotient of 14 times a number x and 9

AURORKA [14]

Answer:

$\frac{14x}{9}-5$

Step-by-step explanation:

14 times a number x : 14* x = 14x

Quotient of 14 times a number x an 9 : $\frac{14x}{9}$

5 less the quotient of 14 times a number x and 9 :

$\frac{14x}{9}-5$
