Problem. 1 : Find an approximation of the area of the region R under the graph of f by computing the Riemann sum of f corresponding to the partition of the interval into the suhintervals shown in the gure. Use the midpoints of the subintenrals as the representative points. [Round your answer to two decimal places.) Problem. 10 : A certain company manufactures a toaster oven. Management has determined that the daily marginal cost function associated with producing these toaster ovens is given by C'(:r) = 0.00020 :32 0.12 :r + 27 where O\"(:r) is measured in dollars per unit and :1: denotes the number of units produced. Management has also determined that the daily xed cost incurred in the production is $900. (a) Find the total cost incurred by the company in producing the rst 300 units of these toaster ovens per day. Round your answer to the nearest dollar. $ 5220 X (b) What is the total cost incurred by the company in producing the 201st through 300th units / day? Round your answer to the nearest dollar. $
