Fixed costs are associated with Multiple Choice   highly adjustable inputs such as labor.   both the short run and the long run.   the short run only.   the long run only.

None

Lines that represent bundles of inputs that cost the same total amount are called: cost curves. isoquants. isoprofit curves. O isocost curves. Ototal cost curves.

The feature that distinguishes short-run from the long-run is the*length of time it takes to produce 1 unit.existence of fixed costs.amount of variable resources used to produce 1 unit.the amount of profit the firm can expect to earn. The short-run is*less than a year.when a firm is unable to change some of its inputs.when a firm is unable to change output.when a firm is unable to change its price. The production function tells the firm*which input combination has the lowest total cost.which input combination produces a given output at the lowest possible cost.the maximum output that can be produced from a given amount of inputs.which output is the most profitable. In the short run*all costs are variable.all inputs are fixedthere may be fixed and variable inputs.all production decisions must be made on a daily basis. The law of diminishing marginal returns says that as units of labor are added to the production of an output when all other inputs are fixed, eventually*total product…
