Answer:
A regular polygon is a polygon that is equilateral and equiangular.
The only regular quadrilateral is the square.
We know that all the interior angles of a square are 90° each, so we are fine with that.
Now, for the exterior angles.
If we fix our position in the vertex, we can do from one side, to the same side, a full rotation of 360°.
Now, if we only do an external rotation, this means, from one side to other side, we will do a rotation of 360° minus the interior angle:
this is:
360° - 90° = 270°
Below is an image as a guide of this.
Distance formula : d = sqrt (x2 - x1)^2 + (y2 - y1)^2
(-5,-1)(-1,12)
d = sqrt (-1-(-5)^2 + (12 - (-1)^2
d = sqrt (-1 + 5)^2 + (12 + 1)^2
d = sqrt (4^2) + (13^2)
d = sqrt (16 + 169)
d = sqrt 185
d = 13.60 <==
For the first question, the answer would be clustering. It is when the data points are close to each other. The answer, for the second question, would be positive. As the height increases, correspondingly, the weight increases as well. For the third question, I think it would be linear since as time passes your salary would increase depending on a rate.
34.49 cubic centimeters
Here is the math
(4/3)•(3.14)•(2cm)^3= (4/3)•(3.14)•(8)=34.49 cubic centimeters
