Select the correct answer.
Vector u has its initial point at (21, 12) and its terminal point at (19,-8). Vector v has a direction opposite that of u, whose magnitude is five times
the magnitude of v. Which is the correct form of vector v expressed as a linear combination of the unit vectors i and?
OA. V=-101+4)
OB. v= -0.4 - 4
OC.
v=0.41 +4j
OD. v = 151 + 100
