The Scientific Method. The Scientific Method is an organized way that helps scientists (or anyone!) answer a question or begin to solve a problem. There are usually six parts to it. 1  Purpose/Question â What do you want to learn? 2  Research â Find out as much as you can. 3  Hypothesis â After doing your research, try to predict the answer to the problem.  Experiment â The fun 1  part! Analysis â Record what happened during the experiment.
Economic Definition of long-run average cost. Offline Version: PDF. Term long-run average cost Definition: The per unit cost of producing a good or service in the long run when all inputs are variable. In other words, long-run total cost divided by the quantity of output produced.
Mathematically expressed, the long-run average cost curve is the envelope of the SAC curves. In this figure 13.7, the long-run average cost curve of the firm is lowest at point C. CM is the minimum cost at which optimum output OM can be, obtained.n the short run, the shape of the average total cost curve (ATC) is U-shaped. The, short run average cost curve falls in the beginning, reaches a minimum and then begins to rise.
