Question

If u = (1,3) and v=(2,6) find u + v

Answer 1

Answer:

C

Step-by-step explanation:

Answer 2

Answer:

Third option <3, 9>

Step-by-step explanation:

u and v are two vectors and we know the Cartesian components of these vectors.

We must find the sum of u + v.

If we have the Cartesian components of both vectors then the sum of both is done by adding the components of u with the components of v.

$u = \\v =$

$u + v = (1 + 2) i + (3 + 6) j$

Where i is the vertical component and j is the horizontal component

Then u + v is

$u + v = (3) i + (9) j$

$u+v =$
