# What is the rate of change of y with respect to x when t = 3 ?

An object moves in the xy-plane so that its position at any time t is given by the parametric equations x(t)=(t^3)-(3t^2)+2 and y(t)= square root of ((t^2)+16). What is the rate of change of y with respect to x when t = 3 ?

A=1/90

B=1/15

C=3/5

Hint: dx/dx = (dy/dt)/(dx/dt).

Hopefully no one will spoil you the answer thereby depriving you from your personal enhancement; that would be very inconsiderate of them.
