Triangle abc has vertices a(0,0), b(2,2) and c(5,-1). find the coordinates of l, the midpoint of line ac, and m, the midpoint of line bc. verify that line lm is parallel to line ab, and line lm is half of line ab.

The coordinates of L are :(5/2,-1/2)

The coordinates of M are :(7/2,1/2)

Hence , LM is parallel to AB since the midpoint theorem states that the line joining the midpoints of any two sides of a triangle is parallel to the third side and is half or 1/2 of the third side

Step-by-step explanation:

We know ,

Midpoint of line xy=(x1+x2)/2 , (y1+y2)/2

" " " "AC=(0+5)/2 , (0+(-1))/2

=5/2 , -1/2

Again,

Midpoint of BC= (2+5)/2 , (2+(-1))/2

" " " " = 7/2 , 1/2

Now ,

Since L and M are the midpoints of AC and BC respectively , the line formed by them i.e. LM is the line that connects the midpoints of any two sides of a triangle and according to the midpoint theorem of triangle , the line joining the two midpoints is parallel to the third side and half its length .

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.
