Question

find the vector from the origin to the point of intersection of the medians of the triangle whose vertices are:A(5,2,1) B(-4,7,0) and C(5,-3,5) ?
​

Answer 1

Answer:

2i^+2j^+2k^

Step-by-step explanation:

so here first get intersection of medians i.e)

x1+x2+x3/3 use same for y and z coordinates

we get median intersection point==(2,2,2)

now equation of vector joining (0,0,0) and (2,2,2)

= (2-0)i^+(2-0)j^+(2-0)k^

=2i^+2j^+2k^
