# Finding a Vector In Exercises 83-86, And the sector v with the given magnitude and the same direction as n.Magnitude Direction ‖ v ‖ = 7 u = 〈 − 4 , 6 , 2 〉

To determine

To calculate: The vector v with magnitude v=7 and direction same as vector u=4,6,2.

Explanation

Given:

The magnitude of vector v is v=7 and the direction of vector v is same as vector u=4,6,2.

Formula used:

Direction of a vector is:

v^=vv

Calculation:

Consider, u=4,6,2

u=(4)2+62+22=16+36+4=56=214

u^=12144,6,2=1<
