Use the dot product to determine whether v and w are orthogonal.
nata0808 [166]

Answer:

B. The vectors v and w are orthogonal because their dot product is <u> 0 </u>

Step-by-step explanation:

Given that :

v=  - i - j  

w= - i + j

Therefore;

vw = ( - i - j )  ( - i + j )

Taking each  set of integer of the vector into consideration:

vw = ( -1 × - 1) ( -1 × 1)

vw = 1 - 1

vw = 0

Hence, we can conclude that :

The vectors v and w are orthogonal because their dot product is <u> 0   </u>
