Question

find the points which divide the join of?​

Answer 1

HEYA!

LET THE CO-ORDINATES OF THAT POINT BE ( x , y , z )

BY USING SECTION FORMULA WE HAVE.

x = (m1 x2 + m2 x1 )/( m1 + m2 )

Here m1 = 1 , m2 = 3

x1 = 1 And x2 = 3

x = ( 3 + 3 )/(4)

x = 6/4

x = 3/2.

y = ( m1 y2 + m2 y1 )/ ( m1 + m2 )

Here, y1 = -2 And y2 = 4

y = ( 4 - 6 ) / (4)

y = -1/2

Similarly for z

z = ( m1 z2 + m2 z1 )/ ( m1 + m2 )

Here, z1 = 3 And z2 = -5

z = ( -5 + 9 )/(4)

z = 1

So, the co-ordinates of that point are

( 3/2 , -1/2 , 1 )
