Determine if the pairs of vectors below are "parallel", "orthogonal", or "neither".
1. a = (-3, 3, -5) and b = (-6, 6, 36/5) are
2. a = (-3, 3, -5) and b = (-6, 6, -10) are
3. a = (-3, 3, -5) and b = (12, -12, 19) are

1.Orthogonal

2.Parallel

3.Neither

Step-by-step explanation:

We have to find pair of vectors are parallel , orthogonal or neither.

1.a=(-3,3,-5) and b=(-6,6,36/5)

We know that when vectors are parallel then,

When vectors are orthogonal then,

Hence, the vectors are not parallel.

Hence, the vectors are orthogonal.

b.a=(-3,3,-5), b=(-6,6,-10)

Hence, the vectors are parallel.

3.a=(-3,3,-5) and b=(12,-12,19)

Hence, the vectors are not orthogonal.

Hence, the vectors are not parallel.

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day
