Answer: C

Step-by-step explanation:

the inner product of (a,b) * (c,d) is ac + bd

= 3 * 4 + 5 * -2

= 12 - 10

= 2

since the inner product is not 0, the vectors are not perpendicular

Answer:

C

Step-by-step explanation:

a.b = (x1 × x2) + (y1 × y2)

= (3×4) + (5×-2)

= 12 - 10

= 2

Hence not Perpendicular
