Determine whether the statement is true or false. If it is true, explain why. If it is false, explain why or give an example tha

frosja888 [35]

Answer:

False

Step-by-step explanation:

the dot product between two vectors A and B is:

A·B=AB $cos\theta$

where $\theta$ is the angle between the vectors, if they are parallel, this angle is zero. so $\theta=0$

and so the dot product is:

A·B =AB $cos(0)$

and since $cos (0)=1$

the dot product is equal to

A·B=AB

The dot product of parallel vectors is NOT zero
