k->1.2k .. etc can you do it now ?
OpenStudy (anonymous):
the answer is 0 i suppose ............. as T is directly proportional to x/y and x, y, both change as x+20x,y+20y so the variable T does not increase
OpenStudy (anonymous):
but you got k there as well..
OpenStudy (anonymous):
oh sorry please dont mind iam really sorry for that its 20%
OpenStudy (anonymous):
yes.. that's right
