can anyone help we with a center of mass problem? i have the general idea i just need help setting up the equations
find the center of mass of a thin triangular plate bounded by the y axis, y=3x+4, and y=14-2x. it has a density of p(x,y)=2x+7y+3.

anonymous · Answer

do i assume it also means its bounded by the x axis?

klimenkov · Answer

Do you know how to integrate?

anonymous · Answer

yes

anonymous · Answer

and i know the center of mass equations but i cant seem the get the right answers so i think im setting them up incorrectly

klimenkov · Answer

Can you solve it right here?

anonymous · Answer

?

amistre64 · Answer

so not assume it is bounded by the x axis if it is not stated

anonymous · Answer

OH MAN. i think i have been trying to do the wrong region...

anonymous · Answer

i think i can get it now lol let me try. ill post another if i cant seem to get it
