How do you know if two vectors are orthogonal?

• Their sum is 0.

• The dot product is 1.

• The angle between them is 0°.

• The dot product is 0.

If w = <2, -5> and y = <2, 0>, find 2w + y

• <-10, 2>

• <4, -5>

• <-6, 10>

• <6, -10>

If the dot product of two vectors are equal to zero, then what do we know about the two vectors?

• They are parallel.

• They are orthogonal.

• They are neither.

The _______ of two or more vectors is the sum of the vectors.

• components

• scalar

• resultant

• magnitude
