**6) The number of cars produced when x dollars is spent on labor and y dollars is spent on capital invested by a manufacturer can be modeled by the equation \(30x^{\frac{1}{3}}y^{\frac{2}{3}} = 360\). (Both x and y are measured in thousands of dollars.)**

  a. Find \(\frac{dy}{dx}\) and evaluate at the point (27, 8).

  b. Interpret the result of a.

**7) Suppose that a particle moves along a straight line with velocity defined by \(v(t) = t^2 - 3t - 18\), where \(0 \leq t \leq 6\) (in meters per second). Find the displacement at time t and the total distance traveled up to \(t = 6\).**
