It is requested to debate and discuss the solution of the following problem It is estimated that the production of a mining deposit can be modeled according to the function P(T)=(-t+20t)/(t+1)^2 where pt is given in millions of tons per year and t in years From t=0 the extraction tasks begin If it is considered profitable for the mine to have a production of 1 million tons per year What would be the useful life of the reservoir? How much and in what year do we have maximum production? How long will it take to completely run out of ore? Make the graph of the function to better understand what is proposed.
