Vector A is given by A = c x + 6 y, and vector B is given by B = 4.8 x - 16.2 y, where x and y are the x and y unit vectors. What does c need to be such that these two vectors are perpendicular?

Question

Vector A is given by A = c x + 6 y, and vector B is given by B = 4.8 x - 16.2 y, where x and y are the x and y unit vectors.  What does c need to be such that these two vectors are perpendicular?

Ron · Answer

Remeber that perpendicular means that the slopes are negative reciprocals of each other
