The consumption of tungsten (in metric tons) in a country is given approximately by p(t)=140 +1,070t+14,912, where t is time in years and t = 0 corresponds to 2010. (A) Use the four-step process to find p'(t). (B) Find the annual consumption in 2027 and the instantaneous rate of change of consumption in 2027, and write a brief verbal interpretation of these results. (A) p'(t) = (B) The annual consumption in 2027 is metric tons. (Simplify your answer.) The instantaneous rate of change of consumption in 2027 is metric tons. (Simplify your answer.) Interpret these results. In 2027, metric tons of tungsten are consumed and this quantity is increasing at the rate of tons per year. (Simplify your answers.) metric
