Halla la medida del lado de un cuadrado cuya diagonal es de 14 cm

8_murik_8 [283]

Answer:

The length side of the square is $7\sqrt{2}\ cm$

Step-by-step explanation:

<u><em>The question in English is</em></u>

Find the measure of the side of a square whose diagonal is 14 cmd

Let

d ----> the diagonal of a square in cm

b ---> the length side of a square in cm

we know that

Applying the Pythagorean Theorem

see the attached figure to better understand the problem

$d^2=b^2+b^2$

$d^2=2b^2$

we have

$d=14\ cm$

substitute the given value

$14^2=2b^2$

solve for b

$196=2b^2$

$98=b^2$

take square root both sides

$b=\sqrt{98}\ cm$

simplify

$b=7\sqrt{2}\ cm$

( 6 − √ 100 − 6 ⋅ 6 ) 3 − 9 ÷ 3

sergij07 [2.7K]

Answer:

(6 - √ 100 - 6 * 6) 3 - 9 ÷ 3 = -64003/1 = -64003

Step-by-step explanation:

1.Square root: sqrt(100) = √ 100 = 10

2.Subtract: 6 - the result of step No. 1 = 6 - 10 = -4

3.Multiple: 6 * 6 = 36

4.Subtract: the result of step No. 2 - the result of step No. 3 = -4 - 36 = -40

5.Exponentiation: the result of step No. 4 ^ 3 = (-40) ^ 3 = -64000

6.Divide: 9 / 3 = 3

7.Subtract: the result of step No. 5 - the result of step No. 6 = -64000 - 3 = -64003

What are the slope between (-5,-2) and (8,13)

Cerrena [4.2K]

Answer:

The slope:

$m = \frac{15}{13}$

Step-by-step explanation:

-To determine the slope of the following points shown, you need this formula:

$m = \frac{y_{2} - y{1}}{x_{2} - x_{1}}$

( $m$ represents the slope, $(x_{1}, y_{1})$ represents the first coordinate and $(x_{2},y_{2})$ represents the second coordinate)

-Apply the following points to the formula:

$m = \frac{13 + 2}{8 + 5}$

Then, solve:

$m = \frac{13 + 2}{8 + 5}$

$m = \frac{15}{13}$

So, the slope is $\frac{15}{13}$ .
