Distance between two points, d, is given by
d= \sqrt{ ( x_{2} - x_{1}) ^{2} + (y_{2} - y_{1}) ^{2} }

where: (x1, y1) = (-1, 0) and (x2, y2) = (8, 6)
d= 
\sqrt{ ( 8 - (-1)) ^{2} + (6 - 0) ^{2} } \\ d= \sqrt{ (9)^{2} + 6^{2} }  
\\ d= \sqrt{81+36}  \\ d= \sqrt{117}  \\ d=10.8 \ units

A circle is the set of all points that are the same distance from one given point. find an example that contradicts this definit
lyudmila [28]

The accurate definition is that the circle that's closest to the 2 dimensional figure where all the set of point in the plane should be equal distance.

<h3>How to illustrate a circle?</h3>

A circle simply means the set of all the points that are the same distance from a given point.

In this case, the contradiction is that the definition should be applied to three dimensional space so that it will be a sphere.

The accurate definition is that the circle that's closest to the 2 dimensional figure where all the set of point in the plane should be equal distance. A example is a point or line.

What is the equation of the line represented by the table below? Х-2,-1,0,1,2 y16,11,6,1,-4
pashok25 [27]

Answer:

y = -5x + 6

Step-by-step explanation:

General equation of a line : y = mx + c......where c is intercept

To find m pick any two points..

(-2, 16) and (-1, 11)

Using (y - y¹) / (x - x¹)

(11 - 16) / (-1 - [-2]) = -5 / 1

= -5

To find c sub with any point for (x, y) and m

using (2, -4)

y = mx + c

-4 = -5(2) + c

-4 = -10 + c

6 = c

Input the values of m and c in the general equation without x and y

; y = -5x + 6

PLEASE HELP ME!!<br> .<br> . Not sure how to do thisssss
tino4ka555 [31]

√72 = √4 * √18 = 2√18. Therefore her answer is incorrect.

√72 = √4 * √9 * √2 = 6√2.

Since √2 is approximately 1.41,

6 * 1.41 = 8.46 = 8.5 (nearest tenth).
