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:

v = [- 10 / 13, 24 / 13]
v = [- 5 / 13, 12 / 13]
v = [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:

v = k · u

Where 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

v = (2 / 13) · [- 5, 12]

v = [- 10 / 13, 24 / 13]

b) The equation of the vector:

v = (1 / 13) · [- 5, 12]

v = [- 5 / 13, 12 / 13]

c) The equation of the vector:

v = (- 10 / 13) · [- 5, 12]

v = [50 / 13, - 120 / 13]

Otrada [13]

The equation is:
y = 10 sin(π/15 t) + 30
where 30 represents the initial height of the blade above the ground and π/15 represents the period as we are given that the blade completes two rotation every minute.Finally the 10 represents the length of the blades.

Hope this helps :)

Gianah lives in Milton. She bought a bus ticket to travel to her cousin's house in Orlando. She gets on the bus in Mobile. The d

kirza4 [7]

Answer: A. 300 - 70h = 30

Step-by-step explanation:

Rest of the question is:

Which of these following equations represents the hours, h, the bus has travelled.

The driver is going at 70 kilometers per hour meaning that for every hour that passes, 70km has been traveled. Expression to find the distance travelled given hours is:

= 70h

There are 300km between the two cities and 30km are left in the journey. Expression is therefore:

300 - 70h = 30

This shows that when you find the distance travelled so far and deduct it from 300, you will get 30km.
