Q2. Find the second order partial derivative of x² − y² + 2xz − xy + yz.
The cost (in dollars) of manufacturing one item is given by
C(x, y) = 70 + 4x + 9y
where x is the cost of 1 hour of labor and y is the cost of 1 pound of material.
(a) If the hourly cost of labor is $25, and the material costs $6 per pound, what is the cost of manufacturing one of these items?
2$
(b) Find the partial derivative of C with respect to x.
Cx =
