Suppose both y and x are differentiable functions of t and that the relationship between y and x is expressed by the equation 4x^3+3y^5=960. Find and interpret \displaystyle\frac{dy}{dt} when \displaystyle\frac{dx}{dt}=4, x=6, and y=2.
Use the function x=\displaystyle\frac{20000}{\sqrt[3]{2p^2-5}}+350 to find the rate at which the number of instruments sold is changing with respect to time, when the price of an instrument is \$400 and is changing at a rate of \$1 per month.
