Cobb-Douglas production function The output Q of an economic system subject to two inputs, such as labor L and capital K, is often modeled by the Cobb-Douglas production function Q(L, K) = cLaKb, where a. b, and c are positive real numbers. When a + b = 1, the case is called constant returns to scale. Suppose a =
a. Graph the output function using the window [0, 20] × [0, 20] × [0, 500].
b. If L is held constant at L = 10, write the function that gives the dependence of Q on K.
c. If K is held constant at K = 15, write the function that gives the dependence of Q on L.

Roman and Shanice come along in a truck to help pull her out. They attach one end of a tow strap to the front of the car and the other end to the truck's trailer hitch, and the truck starts to pull. Meanwhile, Roman and Shanice get behind the car and push. The truck generates a horizontal force of 377 lb on the car. Roman and Shanice are pushing at a slight upward angle and generate a force of 119 lb on the car. These forces can be represented by vectors, as shown in the figure below. The angle between these vectors is 20.2°. Find the resultant force (the vector sum), then give its magnitude and its direction angle from the positive x-axis. 119 lb 20.2° 377 lb a.
