Question 17 The Dot Product 4j a = 31 a∙b= axbx + ay by + azbz a b = 5i-25 Cos = a.b 191.161 |a| = ax² + ay² | b1 = √√ bx² = -6.69 +11.69 j Part 3 of 3: Given the new vector C = 13.5 cos 30°i + 13.5 sin 30°j. A new vector D = dxi + dyj multiplies C in the scalar product DC that produces the product (dx) (13.5 cos 30°) + (dy) (13.5 sin 30%). What are the components of D (the dx and dy) that make the dot product D.C=0? D = ? O -6.75i-11.69 j or 6.75 i +11.69 j O=-6.75 i+ 11.69 j or 6.75 i 11.69 j O = -6.75 i + 6.75 j 2.5 pts
