Find the geometric mean for the following numbers 32 and 2

1 answer:

8 0

First take the product 2 times 32 is 64 because there are only two numbers the nth root is the square root, and the square root of 64 is 8. Therefore geometric mean of 2 and 32 is 8

Answer:

parallel

Step-by-step explanation:

Solve both equations for y to make it easier to compare them.

2x - 5y = 0 ↔ 5y = 2x, or y = (5/2)x.

y = (5/2)x - 3

Since the slopes are the same, the two lines are parallel.

Answer:

The answer is B ( X>6 )

Step-by-step explanation:

2x+4= 16

2x = 16 - 4

2x = 12

x = 12/2

x= 6

Factor completely: 2x4 − 32.

vazorg [7]

Answer:

Option b) is correct.

The completed factor of given expression is $2(x-2)(x+2)(x^2+4)$

Step-by-step explanation:

Given expression is $2x^4-32$

To find the completed factor for the given expression:

$2x^4-32$ :

Taking the common number "2" outside to the above expression we get

$2x^4-32=2(x^4-16)$

Now rewritting the above expression as below

$=2(x^4-2^4)$ (since 16 can be written as the number 2 to the power of 4)

$=2((x^2)^2-(2^2)^2)$

The above expression is of the form $a^2-b^2=(a+b)(a-b)$

Here $a=x^2$ and $b=2^2$

Therefore it becomes

$=2(x^2+2^2)(x^2-2^2)$

$=2(x^2+4)(x^2-2^2)$

The above expression is of the form $a^2-b^2=(a+b)(a-b)$

Here $a=x$ and $b=2$

Therefore it becomes

$=2(x^2+4)(x+2)(x-2)$

$=2(x+2)(x-2)(x^2+4)$

Therefore $=2(x+2)(x-2)(x^2+4)$

$2x^4-32=2(x-2)(x+2)(x^2+4)$

Option b) is correct.

The completed factor of given expression is $2(x-2)(x+2)(x^2+4)$

Hi!

1.)

a:A u B=

$(1.0. - 5. \frac{1}{2} .e)$

(The same elements are written once.)

b:A u C

$(1.0 - 5. \frac{1}{2} .2)$

c:B u C

$( - 5 .1.e.0.2)$

Note:I used dots to mean commas .

Good work!
