Economic Efficiency Marginal cost is the additional cost imposed by the production of one additional item. Marginal benefit is the additional benefit of producing one additional item. For a certain company, the marginal cost C, in dollars, if it is currently producing n items, is given by C(n)=5+n, and the marginal benefit B, in dollars, is given by B(n)=250.9n. Economic efficiency occurs at the production level where marginal cost and marginal benefit are the same. What production level n gives economic efficiency for this company? Round the function values to one decimal place.
When a certain drug is taken orally, the concentration of the drug in the patitent's blood after t minutes is given by C(t)=0.06t-0.0002t^2, where 0 is less than or equal to t less than or equal to 300 and the concentration is measured in mg/L. A) when does the maxinum occur and waht is the maxinmun concentration. B) over what time intervals was the concentration increasing and decreasing? what are the natural domain and range of the function? C) What is the average rate of change of the concectration from 0 to the t-coordinate, t^*, of the vertex and what is its interpetation?
1. The graph of a function y=f(x) always crosses the y-axis. True or False2. Every graph represents a function.A. the statement is true because every graph associates a unique x-value for each y-valueB. the statement is true because every graph associates a unique y-value for each x-valueC. the statement is false because a graph that crosses the x-axis two times does not represent a functionD. the statement is false because a graph that crosses the y-axis two times does not represent a functionI need those answers solution
