Answer:
no
Step-by-step explanation:
because the x repeats
Answer:
False
Step-by-step explanation:
the <u>dot product</u> between two vectors A and B is:
A·B=AB
where
is the angle between the vectors, if they are parallel, this angle is zero. so
and so the dot product is:
A·B =AB
and since 
the dot product is equal to
A·B=AB
The dot product of parallel vectors is NOT zero
Answer:
90
60
5
-10
-25
-45
Step-by-step explanation:
