Question

PLEASE HELP I WILL MEDAL

The ordered pairs <-8, 2> and <5, -6> represent two vectors. What is the magnitude of the resultant?

Answer 1

A. 1
B. 2
C. 5
D. 15

Answer 2

pleas help

Answer 3

well, was wondering what the "resultant" stand for

Answer 4

i dont even know

Answer 5

the resultant is the problem, btw where there any angles in the question or was that it?

Answer 6

the magnitude is just the distance between x,y points, nothing to it, a simple pythagorean theorem can get that, now, the resulant, sounds like a sum, but dunno on that

Answer 7

resultant of <a,b> and <c,d>
is <a+c,b+d>

Answer 8

it was just this

Answer 9

so the resultant is just the sum of vectors

Answer 10

but it's only one digit

Answer 11

well.... notice myininaya 's line above, tis the sum, add them up, then get the magnitude of their sum

Answer 12

how

Answer 13

well. begs the question why you're doing the exercise... you're supposed to know already how I'd think, otherwise there's no point of the exercise

Answer 14

check your material on adding vectors, though myininaya summarized it above anyway

Answer 15

that's the thing, i dont understand it

Answer 16

not this one

Answer 17

\(\bf <a,b>+<c,d>\implies <a+c,b+d>
\\ \quad \\
\textit{magnitude of a vector}\qquad <x,y>\implies \sqrt{x^2+y^2}\)

Answer 18

oh wow

Answer 19

thanks i feel dumb
