(x+1) (2+2)
c
find the ratio
ratio in n
and (3,0) are divided​

Answer 1

Answer:

Let, P(x1,y1,z1)  and Q(x2,y2,z2) be two points. Let, R be a point on the line segment joining P and Q internally in the ratio k:1. Then co-ordinates of R are,

R=(k+1kx2+x1,k+1ky2+y1,k+1kz2+z1)

A(2,1,5) and B(3,4,3)

Let, C be the point that divides in the ratio k:1 then,

C=(k+13k+2,k+14k+1,k+13k+5)

C lies on the plane 2x+2y−2z=1

⟹2(k+13k+2+
