You are a manager of a firm with a following demand and cost functions in a perfectly competitive market. The price in your market is $35. Your total cost curve is: TC = 10 + 2Q + 0.5Q^2
There are 90 identical profit-maximizing, price taker firms in the industry, each with an average variable cost curve of Ave = $8 +$0.75Q and fixed costs of $600 per hour. Q is the output per hour for the firm.
A horizontal block-spring system with the block on a frictionless surface has total mechanical energy E = 42.3 J and a maximum displacement from equilibrium of 0.259 m, Find the potential energy stored in the spring when x = 0.160 m
Calculate the equilibrium constant for the reaction. The standard enthalpy change delta H, for a strong acid-strong base reaction is -57.8k J. Determine the standard entropy change delta S for the reaction at 25 degrees C.
