Find the coordinates for the midpoint of the segment with endpoints given 12,4 and -8,8
borishaifa [10]
<h2>Hello!</h2>

The answer is:

The coordinates of the midpoint are:

x-coordinate=2\\y-coordinate=6

<h2>Why?</h2>

We can find the midpoint of the segment with the given endpoints using the following formula.

The midpoint of a segment is given by:

MidPoint=(\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})

We are given the points:

(12,4)\\

and

(-8,8)\\

Where,

x_{1}=12\\y_{1}=4\\x_{2}=-8\\y_{2}=8

So, calculating the midpoint, we have:

MidPoint=(\frac{12+(-8)}{2},\frac{4+8}{2})

MidPoint=(\frac{4}{2},\frac{12}{2})

MidPoint=(2,6)

Hence, we have that the coordinates of the midpoint are:

x-coordinate=2\\y-coordinate=6

Have a nice day!

The length of the sides of the base of the largest of the Great Pyramids of Giza, near Cairo, Egypt, is 230 m. This square pyram
Lorico [155]
For this case we have that the volume of the square pyramid is given by:
 V = ((L ^ 2) * (h)) / 3
 Where,
 L: side of the base
 h: height
 Substituting values we have:
 V = ((230 ^ 2) * (147)) / 3
 V = 2592100 m ^ 3
 Answer:
 
the volume of the pyramid is:
 
V = 2592100 m ^ 3
