What is | -7.9 ? help

Mathematics
1 answer:
Tamiku [17]2 years ago

I think you mean |-7.9| which is the absolute value of 7.9
Absolute value just means how far away it is from zero on a number line.
So the value is always positive. So the positive of -7.9 is 7.9
|-7.9|= 7.9
Good luck!

Find the length of the unknown side. Round your answer to the nearest tenth. (4 points) Image of a right triangle with a leg lab
Anika [276]

using pythagorean theorem

a^2 + b^2 =c^2

a^2 +8^2 =14^2

a^2 +64 = 196

subtract 64 from each side

a^2 = 132

take the square root of each side

a^2 = sqrt (132)

a=11.48912529

a =11.5

noname [10]

Answer:

44,278,106,022,432,739,384.375  =   1/8 of ((1+√5)/2)^100/√5

Step-by-step explanation:

We separate the x10^21 number into 2 so that becomes x10^8 number with decimal of .75 when it is a x10^21 split into 2 large parts and a small subtraction creates the third step. we have found 1/4 then we half.

354224848179261915075 / 4

= 000000000000065478768.75

354224  848179000000000/4

-88556212044.8

= 354 has become a 12 digit number temporary starting with 885 the decimal .8 is simply put in front

3542248481  79-  so it has become a x10^20 number. 885562120448,65478768.75

We arrange the comma's

  88,556,212,044,865,478,768.75

  88,556,212,044,865,478,768.75

  88,556,212,044,865,478,768.75

  88,556,212,044,865,478,768.75  is division by 4

=354224848179261915075

88,556,212,044,865,478,768.75 /2

= 44278106022 (/2) 432739384.375(/2)  in two part.

=  44278106022,432739384.375 replace /2 with comma

= 44,278,106,022,432,739,384.375 replace all other comma.

Answer:

x = 9/8

Step-by-step explanation:

The triangles are similar so we can use ratios to solve

AB         BC

----  = -----------

AD       ED

x            1

----  = -----------

x+9       9

Using cross products

9*x = 1(x+9)

9x = x+9

Subtract x from each side

9x-x = x+9-x

8x = 9

Divide by 8

8x/8 = 9/8

x = 9/8

Factorise 3ab²+15a²b³+21a³b²​
evablogger [386]

Given:

The expression is

3ab^2+15a^2b^3+21a^3b^2

To find:

The factor form of the given expression.

Solution:

We have,

3ab^2+15a^2b^3+21a^3b^2

Taking out the common factors, we get

3ab^2(1+5ab+7a^2)

It is clear that (1+5ab+7a^2) cannot be factories further.

Therefore, the factorized form of the given expression is 3ab^2(1+5ab+7a^2).
