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? see picture for answer choices.

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

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
