Question

Determine the values of a and b in the following vectors for the indicated property.

m=<10,a,15> and n=<2,-3,b> and vector m is parallel to vector n.

Thanks in advance!

Answer 1

if they are parallel, then the lengths will be proportional.

10/2 = 5, so the ratios of the other dimensions will also be 5:1

Answer 2

In this case, would a=-15 and b=3?

Answer 3

looks good to me.
