In this problem you will calculate ∫305x3dx by using the formal definition of the definite integral: ∫baf(x)dx=limn→[infinity][∑k=1nf(x∗ k)Δx]. (a) The interval [0,3] is divided into n equal subintervals of length Δx. What is Δx (in terms of n)? Δx = (b) The right-hand endpoint of the kth subinterval is denoted x∗k. What is x∗k (in terms of k and n)? x∗k = (c) Using these choices for x∗k and Δx, the definition tells us that ∫305x3dx=limn→[infinity][∑k=1nf(x∗k )Δx]. What is f(x∗k)Δx (in terms of k and n)? f(x∗k)Δx = (d) Express ∑k=1nf(x∗k)Δx in closed form. (Your answer will be in terms of n.) ∑k=1nf(x∗k)Δx = (e) Finally, complete the problem by taking the limit as n→[infinity] of the expression that you found in the previous part. ∫305x3dx=limn→[infinity][∑k=1nf(x∗k )Δx] =

Every weekday, mr. jones bikes from his home to his job. sometimes he rides along two roads, the long route that is shown by the solid lines. other times, he takes the shortcut shown by the dashed line. how many fewer kilometers does mr. jones bike when he takes the shortcut instead of the long route?
