Your Answer is 1/14

PLZ MARK ME BRANLIEST

Step-by-step explanation:

Apply the square root to each part:

sqrt(1) = sqrt(1^2) = 1

sqrt(196) = sqrt(14^2) = 14

The general rule is sqrt(x^2) = x where x is any positive number.

Note how

(1/14)*(1/14) = (1*1)/(14*14) = 1/196

showing that 1/14 multiplied with itself is 1/196. The square root just thinks of this process in reverse. You start with 1/196 and end up with 1/14.

Answer:

1/13

Step-by-step explanation:

√ 1/196 = (1/196)*(1/2)

= (1)*(1/2)/(13)^(2×1/2)

=1/13

Find the perimeter of the quadrilateral that has vertices at (8,13), (5,-18), (-6,-6), and (-2,-5).

kodGreya [7K]

Answer:

72.14 units

Step-by-step explanation:

Let A(8,13), B(5,-18),C(-6,-6) and D(-2,-5)

Apply the distance formula as;

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Finding the lengths of the segments

For AB

$AB=\sqrt{(5-8)^2+(-18-13)^2} =\sqrt{(-3^2)+(-31^2)} =\sqrt{970} =31.14$

For BC

$BC=\sqrt{(-6-5)^2+(-6--18)^2} =\sqrt{(-11^2)+12^2} =\sqrt{265} =16.28$

For CD

$CD=\sqrt{(-2--6)^2+(-5--6)^2} =\sqrt{4^2+1^2} =\sqrt{16+1} =\sqrt{17} =4.12$

For DA

$DA=\sqrt{(8--2)^2+(13--5)^2} =\sqrt{10^2+18^2} =\sqrt{424} =20.6$

Finding the perimeter will be;

31.14+16.28+4.12+20.6=72.14 units

Which inequality represents this sentence ? 7 5 is greater than 6 2

75 > 62
the way I was taught it is that the < and > are alligators and the alligator mouth always opens for the bigger number, because he is hungry

A family is driving from Phoenix to San Francisco. On a map grid, Phoenix is located at (–12, –16), and San Francisco is located

asambeis [7]

The total distance that the family has driven is the sum of the distances from Phoenix to San Francisco,
d = sqrt ((5 - -16)² + (-36 - -12)²) = 10.63
from San Francisco to Blythe,
d = sqrt ((-9 - 5)² + (-20 - -36)²) = 21.26
from Blythe to Los Angeles,
d = sqrt ((-4 - -9)² + (-33 - - 20)²) = 5.83
Adding the distances, we get 37.72.
