Let's consider each of the option....

Radio wave is an electromagnetic wave ; what is an electromagnetic wave?? An electromagnetic wave are waves that does not require material medium for their propagation... So radio wave can move through a vacuum because it's an electromagnetic radiation...

Sound wave is a mechanical wave ; what is a mechanical wave?? Waves that require material medium for their propagation.. Other examples include :water wave,

Light wave is also an electromagnetic wave(radiation) it does not require a material medium for its propagation it defines every other electromagnetic wave other example including... ; gamma ray, X-ray, ultraviolet ray, visible light, infrared Ray, radio wave(which I discussed first)

Sound wave can not move through a vacuum because it requires a material medium..
You can talk to someone and the person hears you because the air particles serves as the material medium....

Hope this helps..........

Which expression is equivalent to -7(y-2)

soldi70 [24.7K]

Hello!

Distributive property: a(b+c)=ab+ac

$a=-7, b=y, c=2$

$-7y-(-7)*2$

Minus and plus sign.

$-7y+7*2$

Then multiply by the numbers.

$7*2=14$

$\boxed{=-7y+14}$

Hope this helps!

Thanks!

Have a great day!

The endpoints of `bar(EF)` are E(xE , yE) and F(xF , yF). What are the coordinates of the midpoint of `bar(EF)`?

Hoochie [10]

For a better understanding of the solution provided here please find the diagram attached.

Please note that in coordinate geometry, the coordinates of the midpoint of a line segment is always the average of the coordinates of the endpoints of that line segment.

Thus, if, for example, the end coordinates of a line segment are $(x_{1}, y_1)$ and $(x_2, y_2)$ then the coordinates of the midpoint of this line segment will be the average of the coordinates of the two endpoints and thus, it will be:

$(\frac{(x_1+x_2)}{2}, \frac{(y_1+y_2)}{2})$

Thus for our question the endpoints are $(x_E, y_E)$ and $(x_F, y_F)$ and hence the midpoint will be:

$(x_M, y_M)=$ $(\frac{(x_E+x_F)}{2}, \frac{(y_E+y_F)}{2})$

Thus, Option C is the correct option.
