But, it is actually possible to talk about linear combinations of anything as long as you understand the main idea of a linear combination: (scalar)(something 1) + (scalar)(something 2) + (scalar)(something 3) These "somethings" could be "everyday" variables like \\(x\\) and 12. (average), calculate the velocity (magnitude) of the plane relative to the ground. A smaller plane with the same acceleration has a takeoff speed of 40 M/S. It's not the fastest way, but a reasonably quick way is to just hit an (initially random) vector with the matrix repeatedly, and then normalize every few steps. C. 1.6 HZ A.
