Thanks in advance!
A conceit promoter sells tickets and has a marginal-profit function given below, where P' (x) is in dollars per ticket. This means that the rate of change of total profit with respect to the number of tickets sold. x. is P'(x). Find the total profit from the sale of the first 290 tickets, disregarding any fixed costs. P'(x) = 2x - 1031 The total profit is (Round to the nearest cent as needed.) A company that produces ribbon has found that the marginal cost of producing x yards of fancy ribbon is given by C'(x) = - 0.00002x2 - 0.04x + 33 for le 600, where C'(x) is in cents. Approximate the total cost of manufacturing 600 yards of ribbon, using 5 subintervals over [0.600] and the left endpoint of each subinterval. The total cost of manufacturing 600 yards of ribbon is approximately . (Do not round until the final answer. Then round to the nearest cent as needed.) A juice company has found that the marginal cost of producing x pints of fresh-squeezed orange juice is given by the function below, where C'(x) is in dollars. Approximate the total cost of roducing 270 pt of juice, using 3 subintervals over [0270] and the left endpoint of each subinterval. C'(x) = 0.000007x2 - 0.0035x+ 2, for x le 350 The total cost is about . (Round the final answer to the nearest cent as needed. Round all intermediate values to the nearest thousandth as needed. Approximate the area under the graph of f(x) = 0.03x4 - 1.96x2 + 85 over the interval [3.11 ] by dividing the interval into 4 subintervals. Use the left endpoint of each subinterval. The area under the graph of f(x) = 0.03x4 - 1.96x2 + 85 over the interval [3.11 ] is approximately . (Simplify your answer. Type an integer or a decimal.)Explanation / Answer
