Find the coordinates of the midpoint of the segment.<br> MN with endpoints M (4, 10) and N(-2,-6)
Georgia [21]

Answer:

The answer is

<h2>( 1 , 2)</h2>

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

M  = ( \frac{x1 + x2}{2} , \:  \frac{y1 + y2}{2} )

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

M (4, 10) and N(-2,-6)

The midpoint is

M = ( \frac{4 - 2}{2}  , \:  \frac{10 - 6}{2} ) \\  = ( \frac{2}{2}  \: , \:  \frac{4}{2} )

We have the final answer as

<h3>( 1 , 2)</h3>

Hope this helps you

Maxine is buying extra pages for her photo album. Each page holds exactly 8 photos. Sketch a graph to show the maximum number of
erastovalidia [21]
Ok so I can't sketch a graph for you because I don't know how to but i can give a formula that will help you graph it on your own. The equation is y = 8x having x represent the amount of extra pages you want to add. I came to this equation because if 8 photos can fit in each extra page and x represents the the extra pages then 8 photos is the slope for the equation y = mx + b. So if you were to graph this you will get a continuous line because it has no holes.

In ΔVWX, the measure of ∠X=90°, XW = 36, WV = 85, and VX = 77. What ratio represents the sine of ∠W?
eimsori [14]

<u>Given</u>:

In ΔVWX, the measure of ∠X=90°, XW = 36, WV = 85, and VX = 77.

We need to determine the ratio that represents the sine of ∠W

<u>Ratio of sin of ∠W:</u>

The ratio of sin of ∠W can be determined using the trigonometric ratios.

The ratio of sin \ \theta is given by

sin \ \theta=\frac{opp}{hyp}

From the attached figure, the opposite side of ∠W is XV and the hypotenuse of ∠W is WV.

Hence, substituting in the above ratio, we get;

sin \ W=\frac{XV}{WV}

Substituting the values, we get;

sin \ W=\frac{77}{85}

Thus, the ratio of sine of ∠W is sin \ W=\frac{77}{85}
