Decompose the vector (5,8). Please help!

Question

anonymous · Answer

not sure what this means
maybe 
$$5\overrightarrow{i}+8\overrightarrow{j}$$

amistre64 · Answer

yep

anonymous · Answer

y=8x/5

anonymous · Answer

really? that is "decompostion"?

amistre64 · Answer

splitting it into its constitueitn parts

anonymous · Answer

that's easy for you to say!

anonymous · Answer

Is y=8x/5 correct? I'm really not sure what this question wants from me, and I'm not sure how to "decompose", so that's why I came here.

anonymous · Answer

decompose is to turn a vector into a sum of other generating vectors which are alongside the Y, X, and Z axis

anonymous · Answer

i am pretty sure (since amistre seconded it) that the answer is what i wrote
or maybe 
$$5\overrightarrow{e_1}+8\overrightarrow{e_2}$$ or even 
$$5(1,0)+8(0,1)$$

amistre64 · Answer

im pretty sure shes not in a linear algebra class ...

anonymous · Answer

Yeah I'm in Geometry, and I'm homeschooled, and my book isn't really explaining it to me!

i think kumar likes to contribute to things just so that you have a choice :)  do you choose good or evil?  lol

anonymous · Answer

is there an example in the book?

anonymous · Answer

i have no idea

anonymous · Answer

It gives a vague lesson on it, basically half a page, but from the looks of it, satellite73's answer makes sense! So thank you for that!

mertsj · Answer

Could it be:
$$x=\sqrt{89}\cos58^{o} , y=\sqrt{89}\sin58^{o}$$

mertsj · Answer

Does that look familiar?

anonymous · Answer

The answer I got was Vx (5,0) Vy (0,8)
I'm not sure how correct that is, but judging from the vague explanation in my book, it seems like it might be correct.

anonymous · Answer

it is. it says in a way that the component in X is 5,0 and in Y is 0,8
adding both you get (5,8)
