Question

Find two vectors v1 and v2 and whose sum is(3,0,2) , where v1 is parallel to(-4,-2,-4) while v2 is perpendicular to (-4,-2,-4)

Answer 1

helpp !!!!!!!

Answer 2

v1+v2=(3,03)
V1=k(-4,-2,-4)

(3+4k,2k,2k+4k).(-4,-2,-4)=0

Answer 3

the third line is a dot product which is zero for orthogonal vectors.
