Question

What is the magnitude and direction of Vector GH if G(2, -2) and H(7, 6)?

magnitude: 9.43 units; direction 32.01°

magnitude: 6.4 units; direction: 57.99°

magnitude: 9.43 units: direction: 57.99°

magnitude: 6.4 units: direction: 32.01°

Answer 1

first off, lets position this at the origin by subtracting one point from the other

Answer 2

H(7, 6)
-G(2, -2)
---------
(5, 10)

this is the position representation of the vector from G to H

Answer 3

since 5,10 is greater than 10,10 (45 degrees) its safe to say that the direction part is 55 or so

Answer 4

Okay

Answer 5

the magnitude is just the length of the vector using the distance formula

Answer 6

square add sqrt ....

(5, 10)

(5, 10)^2 = 25,100

25+100 = 125

sqrt(125) HMMM

Answer 7

caps got stuck :/

Answer 8

Thats okay , no problem!(:

Answer 9

it appears that the magnitude doesnt fit any of the option .... sqrt(125) is about 11 or so

Answer 10

pfft, 6+2 = 8 .. not 10 :) forgot how to add

Answer 11

Lol!!

Answer 12

so id still go with the larger 9 spot and about 55 for the win

Answer 13

Okay! Thanks(:

Answer 14

youre welcome, and with any luck, some of that made sense ;)

Answer 15

Yes it did ! Thank you(:
