Answer

If the dot product of two vectors is 0, they are orthogonal. So, we check the result of our calculation.

Steps

Step 1 :Calculate the dot product of vectors A and B. The dot product is defined as AB=i=1naibi, where ai and bi are the components of A and B respectively.

Step 2 :Substitute the given values into the dot product formula: AB=(1)(4)+(2)(2)+(3)(0)=44+0.

Step 3 :If the dot product of two vectors is 0, they are orthogonal. So, we check the result of our calculation.
