The temperature on a cubic box [0, 4] × [0, 4] × [0, 4] (measured in meters) can be describedby the function T (x, y, z) = x2y + y2z degrees F◦. A fly is in position (1, 2, 1) and takesoff in a straight line to the corner (4, 0, 4). Use directional derivatives to calculate the changein temperature the fly experiences as she takes off. Give your answer with 2 decimal digitscorrect.
Your weekly cost (in dollars) to manufacture x bicycles and y tricycles is
C(x, y) = 12,000 + 40x + 30y.

The marginal cost to manufacture bicycles is the partial derivative of C with respect to x,
which is
dollars per bicycle v
The marginal cost to manufacture tricycles is the partial derivative of C with respect to y,
which is
|dollars per tricycle v
The marginal costs do not
depend on the production level, since the cost function is linear.
Use the Chain Rule to evaluate the partial derivative at the point (q, r) = (2, 3), where h(u, v) = ue" , u = q°, v = qr³.
(Use symbolic notation and fractions where needed.)
