Question

Find the vector v with the given magnitude and the same direction as u. Magnitude ||v|| = 10 Direction u = ⟨-3. 4⟩.

Answer 1

Answer:

(-6,8)

Explanation:

Since v has direction as u, it must be a multiple n of u.

$\sqrt{(-3n)^+(4n)^2}=10\\9n^2+16N^2 =100\\n^2=4\\n=2$

therefore v = (3×2, 4×2) = (-6,8)
