I have general question which need to be answered before I can understand steps which I have to do. There are: When you are told that a solid is bounded by the coordinate plane and the plane [tex]x+10y + 2z = 5[/tex], are the limits considered to be [tex]0-1[/tex] for [tex]x[/tex]-axis, [tex]0-10[/tex] for the [tex]y[/tex]-axis and [tex]0-2[/tex] for the [tex]z[/tex] axis. What is the [tex]=5[/tex] used for in this question? If you are told that the density is directly proportional to the distance from the [tex]y-z[/tex] axis, does that mean that the density is [tex]kx[/tex]? Could you help clear my mind? Thanks in advance.
