Question

The position vector of A has the Cartesian coordinates (20,30,50). The position vector of B has the Cartesian coordinates (10,40,90). What are the coordinates of the position vector of A+B?

Answer 1

`<30, 70, 140>`

Explanation:

When adding vectors, simply add the coordinates.

`A+B=<20, 30, 50> + <10, 40, 90>`

`=<20+10, 30+40, 50+90> = <30, 70, 140>`
