Thanks for the help. I get it now.

They aren't multiplies of each other, so they must be a plane. To find the final vector could I simply say a [1 0 0 0] + b [0 1 0 0] = x Pick arbitrary scalars for a and b, since, by definition, x would have to be in the plane formed by a and b?

Well, that's just a line - but I don't see how that helps me ?

I honestly don't even know where to start with this question. The question is: Give an example of a span of three vectors u, v, w in four dimensions that corresponds to a plane thru the origin? I know that the span of the vectors is the set of linear combinations of the vectors. I don't...

I missed a few days of class and have a quiz tomorrow so I'm not entirely sure where to start with this. The question is: A golfer hits a ball (m = 38 g) from a cliff top (h = 46 m) and times how long it takes to splash in the ocean (t = 7.0 s). The ball hits the water at a distance (x = 154...
