Which equation describes the sum of the vectors plotted below?

It's the third one in the picture ...

r = 3x - 2y

Explanation:

From the attached figure, OAB forms a triangle having,

a = (2,1)

b = (3,-2)

Vector, OA = 2x + y

Vector, AB = x - 3 y

The resultant can be calculated using triangular law of vector addition as :

So, the sum of the vectors plotted below is . Hence, the correct option is (c).

i don't know, you need to give me some answers.

explanation:

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
