Question

My question is:
the vertices of triangle STU are S(0,1), T(4,7), and u(8,-3)

Find the coordinates of the points of concurrency of triangle STU.

Centroid.

Answer 1

I assume you are only looking for the centroid.

The centroid is located at the average of the coordinates.

x = (0 + 4 + 8)/3 = 12/3 = 4
y = (1 + 7 - 3)/3 = 5/3

The centroid is located at (x, y) = (4, 5/3).

Answer 2

9

Answer 3

alright ive spent a godd 10 mintues working on this and i finally have (5.375,1.75) for the centroid

to do this i first had to find the midpoints of each line segment using the (x1+x2)/2 , (y1+y2)/2 for each one and i got,,,

2,4
6,2
4,-1

the i found the perpendicular line going through each one, although as i found out after i finished you really only need two,

i did this using substitution of the x and y coordinates

(-2/3)X+5.333333
(2/5)X -.4
2X - 9

the graph at least two of them and find the intersection ( i used a TI-84)

im currently a sophomore in high school and we did this last year in geometry so i might not have gotten everything right, but im pretty sure. hope i could help =]

Answer 4

if you want the vertices of a triangle congruent to STU, there are an infinite number of solutions. one is (0,2), (4,8), and (8,-2)

Answer 5

9 i think

Answer 6

Ouch.
I thought i was good at math...
*studies more*

Answer 7

answering your question would prove me smart and not answering your stupid question would make me dumb.

Answer 8

what is concurrency or cetroid?

Answer 9

no one is doing your mathhomewok girl.

Answer 10

4,3 i think i did it right
