Answer

Final Answer: vw=9 and vv=45

Steps

Step 1 :Given vectors are v=6i3j, w=2ij

Step 2 :The dot product of two vectors can be calculated by multiplying the corresponding components of the vectors and then adding them together. For vectors in 2D, if v=ai+bj and w=ci+dj, then vw=ac+bd

Step 3 :Substitute the given vectors into the formula, we get vw=(62)+(31) and vv=(66)+(33)

Step 4 :Calculate the above expressions, we get vw=9 and vv=45

Step 5 :Final Answer: vw=9 and vv=45
