WebLets also say that product materials cost half of the price of the product (25 * the number of products), and that running the machine costs 1/10 the number of products squared (5 * products ^2). This can be written as: cost (#products) = 1/10*5 (#products)^2 + 1/2*25 … WebIt is interesting that the cost function uses the square of the L2 norm rather than L2 norm. This is a fortuitous choice that turns out to simplify the math in many ways. Finding the optimal k-means clustering is NP-hard even if k = 2 (Dasgupta, 2008) or if d = 2 (Vattani, edgeworth heights public school uniform https://cartergraphics.net

WebWell, your profit as a function of x is just going to be equal to your revenue as a function of x minus your cost as a function of x. If you produce a certain amount and let's say you bring in, I don't know, $10,000 of revenue and it costs you $5,000 to produce those shoes, you'll have $5,000 in profit. WebCost-minimization problem, Case 1: tangency. If technology satisfies mainly convexity and monotonicity then (in most cases) tangency solution!
