Question

Suppose z=f(x,y) describe the cost to build a certain structure, where x represents the labor costs and y represents the cost to build a certain structure. Where x represents the labor costs and y represents the cost of materials. Describe what fx and fy represents

Answer 1

Answer:

What are the s- and t-derivatives of z = f(st2, tes) at s = 0,t = 2 if the derivatives of z = f(x, y) have the values fx(0, 2) = 10 and fy(0, 2) = −5

Answer 2

Suppose z=f(1.y) describes the cost to build a certain structure, where x represents the labor y represents the cost of materials. Describe what f, and f, represent.
