Best ResponseYou've already chosen the best response.0Y end points is 0 to 4, I can solve for z to find the top what about x?

Best ResponseYou've already chosen the best response.0My guess would be since we are talking about the first octant that all values have to be positive, x goes from 0 to 3 > z = 5(5/3)x z bounded from 0 to 5 >x = 3  (3/5)z x bounded from 0 to 3

Best ResponseYou've already chosen the best response.0i might be oversimplifying this but it seems that this forms a right triangular prism where actually you could do it without integrals V = (1/2)*5*3*4 = 30 If im mistaken i apologize

Best ResponseYou've already chosen the best response.0I understand. It is an exercise: they are trying to teach us how to set up double integrals.

Best ResponseYou've already chosen the best response.0oh ok To determine x look at the linear relationship between z and x, x has to be between 0 and 3 for z to be positive
