Answer:

To find the vertical and horizontal distances between the two points, sometimes this can be seen by looking at the graph, but the vertical and horizontal distances between two points can always be found by subtracting the coordinates of the two points.

What is the distance between (-2,2) and (4,-6) on coordinate plane

PtichkaEL [24]

Hey there!!

How do we find the distance between two coordinate points?

In order to find the distance, we use this formula :

$\sqrt{( x2 - x1 )^{2} + (y2-y1)^{2}}$

The given coordinates :

( -2 , 2 ) and ( 4 , -6 )

x2 = 4 and x1 = -2 ; y2 = -6 and y1 = 2

Now, plug in the values :

$\sqrt{(4-(-2)^{2} + (-6-2)^{2}}$

$\sqrt{6^{2} + (-8)^{2}}$

$\sqrt{36 + 64}$

$\sqrt{100}$

$=50$

Hence, the distance is 50 units.

Hope my answer helps!

Derick studied 13 1/2 hours this week for a spelling bee. Write the number of hours as a decimal.

serg [7]

Answer:

13.5

Step-by-step explanation:

When you convert fraction numbers to decimal numbers, remember they are written like this:

whole . parts

In 13 1/2, you have 13 wholes and 1/2 parts. The decimal number would look like 13 . parts

To find the decimal for 1/2, put into your calculator <u>1 ÷ 2</u>. The answer will be 0.5 Write "5" for parts. The decimal where 0.5 is will line up with the decimal in the decimal number.

13.5

Calculate the sum of the interior angles of the following polygon 6 sided 15 sided and 3 sided

Dvinal [7]

Answer:

720°, 2340°, 180°

Step-by-step explanation:

Look at the attached image of a regular hexagon. I drew all possible lines from a vertex to other vertices (AC, AD, AE). Drawing in all those diagonals splits the hexagon into 4 triangles, and adding up the measures of all the triangle angles would account for all the interior angles of the hexagon.

♦ Four triangles have an angle sum of 180° x 4 = 720° (180° in each triangle).

See attached image2 to see what happens in an octagon. There are six triangles formed, so the total of all interior angle measures is 6 x 180° = 1080°.

What about a 15-sided regular polygon? How many triangles would be formed by putting in all the diagonals coming from one vertex? There will be 2 fewer triangles than the number of vertices, 13.

♦ The total of interior angle measures in a 15-gon is 13(180°) = 2340°

♦ A polygon with 3 sides is a single triangle; interior angle sum = 180°
