Question 1172235: Vector u has its initial point at (15, 22) and its terminal point at (5, -4). Vector v points in a direction opposite that of u, and its magnitude is twice the magnitude of u. What is the component form of v?
a. v=(-20,36)
b. v=(-20,52)
c. v=(20,36)
d. v=(20,52)

The vector v is ((5-15),(-4-22)) = (-10,-26).
The vector -2v is -2(-10,-26) = (20,52).
ANSWER choice d
