Question

Vectors please help?!
find 1/2v+3/5w given v(1,6) and w(-5,-2)

Answer 1

First scalar multiply them. Then add them.

Answer 2

im sorry?

Answer 3

scalar multiply?

Answer 4

yeah
you multiply all of the components by the scalar (the coefficient)

Answer 5

thanks for your help..

Answer 6

think of your vectors in components you have v = i+6j and w = -5i-2j
we need (1/2)(1i+6j)+(3/5)(-5i-2j)
do the math and collect like components
(1/2)i+3j-3i-(6/5)j
-(5/2)i-(9/5)j
so your new vector
is <-5/2,-9/5>
