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 class=

Respuesta :

Answer:

D

Step-by-step explanation:

u = < 5, - 4 > - < 15, 22 > = < 5 - 15, - 4 - 22 > = < - 10, - 26 >

v is in the opposite direction to u, thus is the negative of u

v is also twice the magnitude of u , thus multiply u by 2

Overall to obtain v multiply u by - 2, that is

v = - 2u = - 2 < - 10, - 26 > = < 20, 52 > → D
