1. A company estimates that the marginal cost (in dollars per item) of producing x items is 1.93 - 0.002x. If the cost of producing one item is 558, find the cost of producing 100 items.
2. Use the Midpoint Rule with the given value of n to approximate the integral. Round the answer to four decimal places.
3. Consider the given integral.
(a) Find an approximation to the integral G using a Riemann sum with right endpoints and n = 8.
(b) If f is integrable on [a, b], the following equation is correct.
Use this to evaluate the integral G.
4.Evaluate the integral.
5. Evaluate the integral.
