Approximate the area under the graph of f(x) = 0.04x* - 2.89x" + 96 over the interval [4,12] by dividing the interval into 4 subintervals. Use the left endpoint of each subinterval. The area under the graph of f(x) = 0.04x# - 2.89x + 96 over the interval [4,12] is approximately (Simplify your answer. Type an integer or a decimal.)A concert 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 70 tickets, disregarding any fixed costs P'(x) = 8x - 1137 The total profit is $ (Round to the nearest cent as needed.)Approximate the area under the graph of F[)
