What is the square root of 48? what is the square root of 1/49 ? what is the square root of 4/100 ?
Luba_88 [7]

Answer:

Step-by-step explanation:

√48 = √(3*16) = 4√3

                   

                  √1                                      

√(1/49) = ------- = 1/7

                √49

                       √4

√(4/100) = --------------- = ±2/10 =                                                                                                                                                                                                                                                                                                                                                                              

                     √100

Find the geometric mean of sqrt 77 and sqrt 343.
astraxan [27]

Answer:

12.75

Step-by-step explanation:

The computation of the geometric mean of sqrt 77 and sqrt 343 is given below:

As we know that

Geometric mean = \sqrt{ab}

where

a is the first number = \sqrt{77}

And, the b is the second number = \sqrt{343}

Now first we have to convert into a number

For a it, is = 8.78

And, for b, it is = 18.52

Now the geometric mean is

= \sqrt{8.78 \times 18.52}

= 12.75

• How do you use the distance formula and slope formula to prove properties of polygons?
patriot [66]

Answer:

distance formula= \sqrt{x} (x_{2} -x_{1} )^{2} + (y_{2} -y_{1} )^{2} = find the length(units) using coordinates.

slope formula= m=\frac{rise}{run} =\frac{y_{2}-y_{1}  }{x_{2} -x_{1} }= determines slope of a line using two points on the line(coordinates)

When working with polygons the main properties which are important are:

The number of sides of the shape.

The angles between the sides of the shape.

The length of the sides of the shape.

length , width

straight lines , angles, vertices, vertex

A polygon is any 2-dimensional shape formed with straight lines.

a plane figure with at least three straight sides and angles, and typically five or more.

Step-by-step explanation:

<h2><u>answer= use distance and slope to determine that opposite side of a polygon are the same length and same slope</u></h2>

Which statement is an example of the distributive property? 3 + (2)(15) = 3(2) + 3(15) 3(2 + 15) = 3 + 2(3) + 15 3(2 + 15) = 3(2
natka813 [3]
It would be 3(2+15)= 3(2) + 3(15)
Hope this helps❤️
