Best ResponseYou've already chosen the best response.0take the derivative of r(x) with respect to x dr/dx next take the derivative of dt/dx use the chain rule dr/dt = dr/dx * dx/dt that gives you dr/dt

Best ResponseYou've already chosen the best response.0I think he misread the questions. Assuming I AM reading it right (granted, the notation is a bit weird): For the first one, just divide r(x) by t(x) (divide each term in r(x) by (9x^3). the other two are the same, but with a specific value of x to plug in.

Best ResponseYou've already chosen the best response.0I guess you could call it long division, but it's really just: \[\frac{54x^612x^427x^3}{9x^3} = \frac{54x^6}{9x^3} + \frac{12x^4}{9x^3} + \frac{27x^3}{9x^3} = ... \]

Best ResponseYou've already chosen the best response.0I like that better so how do i apply it to the problem

Best ResponseYou've already chosen the best response.0(Again, this assumed the notation is as I think) Just find that answer to that (the simplified form). Then let x = 3 and 1 for the second and third parts, respectively.

Best ResponseYou've already chosen the best response.0so how do i apply it to (r/t)(x)

Best ResponseYou've already chosen the best response.0... That is what (I assume) (r/t)x means...r(x)/r(t)... does it not?

Best ResponseYou've already chosen the best response.0so my answer to (r/t)(x) is: 6^3+4/3x+3

Best ResponseYou've already chosen the best response.0ok i think i got it now
