5. given the vector [-5,12], find each of the following vectors. a. same direction, twice as long. b. same direction, length 1 (
pshichka [43]

The vectors are listed below:

  1. <u>v</u> = [- 10 / 13, 24 / 13]
  2. <u>v</u> = [- 5 / 13, 12 / 13]
  3. <u>v</u> = [50 / 13, - 120 / 13]

<h3>How to derive the expressions of vectors</h3>

Vectors are characterized by magnitude and direction. The magnitude is a scalar and the direction by a ordered pair, whose formula is shown below:

<u>v</u> = k · <u>u</u>    

Where <u>u</u> is a unit vector, that is, a vector of length 1.

Now we proceed to determine each vector:

a) The equation of the vector:

r = √[(- 5)² + 12²]

r = 13

k = 2

<u>v</u> = (2 / 13) · [- 5, 12]

<u>v</u> = [- 10 / 13, 24 / 13]

b) The equation of the vector:

<u>v</u> = (1 / 13) · [- 5, 12]

<u>v</u> = [- 5 / 13, 12 / 13]

c) The equation of the vector:

<u>v</u> = (- 10 / 13) · [- 5, 12]

<u>v</u> = [50 / 13, - 120 / 13]
