Question

Find the midpoint of the segment with the given
endpoints. M(–2, 1) and O(–3, 2)

A. (–2.5, 1.5)

B. (–0.5, –0.5)

C. (0.5, –0.5)

D. (–3, –5)

Answer 1

its D.

Answer 2

K so a midpoint is basically an average of the x points and of the y points.
The formula is x1+x2 divided by 2, y1+y2 divided by 2. If we do this we get-
(-2+-3) (1+2)
------- & -----
2 2
-5/2, 3/2= (-2.5,1.5)

Answer 3

Ohhhh okay I get it! :D Okay can you help me with one more?

Answer 4

I believe I know the answer but I need to know if I'm right.

Answer 5

Sure.

Answer 9

This one is C what do you think?

Answer 10

Sorry, but Idk this one :( I'm thinking maybe it has something to do w/ tan/cos/sin

Answer 11

Hmmm okay ill figure it out tho... Thank you

Answer 12

Sry :( I think though it has something to do with sine

Answer 13

yeah I just put what I thought :) thanks tho...

Answer 14

This can be solved with trigonometry.
The hypotenuse has been given and the opposite side is needed.
In this case, we will need to use sine.

sin = opposite/hypotenuse
let the opposite side length be y
so sin(36) = y/220
220sin(36) = y
plug that into a scientific calculator and you get
129.3ft
so the answer is D
