If the dot product of two nonzero vectors v1 and v2 is nonzero, what does this tell us?

a) v1 is not perpendicular to v2

b) v1 is a scalar

c) v1 is parallel to v2

d) v1 is perpendicular to v2

ANSWER

A) v1 is not perpendicular to v2

EXPLANATION

Two non-zero vectors are orthogonal or perpendicular if their dot product is zero.

In other words,if two non-zero vectors are not orthogonal or perpendicular then their dot product is not equal to zero.

From the question v1 and v2 are non-zero vectors and their dot product is not equal to zero.

This tells us that, the two vectors are not perpendicular.

The correct choice is A.

its c or d   take a lucky guess my dude

step-by-step explanation:

we need to solve for 'x' the following equation:  

we have that:

⇒
