Ayuda es para hoy Al componer el vector a = [ 15 x – 12 y ] con los vectores b = [ b x – 17 y ], c = [ – 10
x + c y ] , d = [ 8 x – 10 y ], resulta un vector que solo tiene coordenada en el eje de las
abscisas, y su valor es de – 12. Determinar el módulo y dirección de los vectores b y c.

less than one you can't create energy

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.
