Hello…I need help with my calculus problem. see attachment for details.

2. Jason and Mary Kate are having a bike race to see who can bilre the furthest in a set amount oftime. Let fit] and fit} give the velocity of Jason and Mary Kate respectively, in miles per hour, thours after the start of the race. Assume the race lasts for 1.5 hours. A table with some vaiues offit] and a formula for 9:3} are given below. Assume that fit} is increasing for [l -: t -=: {1.5 anddecreasing for [LB «1’. t a: 1.5, and notice that git] is increasing for [I «c: t a: 1.5. mammal-mm IIiI-Iifi-mlm gm = ritet (a) Write a left—hand Riemann sum with as many snbintervals as pomible for the distance traveledby Jason over the course of the race, and evaluate this Riemann sum. (The snhintervals in theRiemann sum do not have to have the same length.) Eb} Write a Riemann sum with as many snbintervals as possible that gives an UNDERESTIMATE forthe distance traveled by Jason over the course of the race, and evaluate this Riemann sum.Sketch a graph that illustrate. why your Riemann sum is an underestimate. (The snbintervalsin the Riemann sum do not have to have the same length.) (c) Write a Riemann sum with E: subintervals of the same length that gives an UNDEREETIMATE for the distance traveled by Mary Kate over the course of the race, and evaluate this Riemannsum. Sketch a graph that illustrates why your Riemann sum is an underestimate. Ed} Write a right—hand Riemann sum with 5 suhintervals of the same length that gives the distance traveled by Mary Kate over the course of the race, and evaluate this Riemann sum. Sketch agraph that illustrates your Riemann sum. (e) Is it possible to tell solely from the estimated distances in the previous parts who traveledfurther? If so, determine who If not, explain why not. {f} Suppose Mary Kate wants to use a Riemann sum to calculate how far she traveled fori] <’.’. t a: 1.5, accurate to within {1.1 miles. How many times would she have to measure hervelocity in order to achieve this accuracy?

   java programmingT1. Write a program that models checkout lines at a supermarket; you have to use one of the data

structures being covered in the lectures and explain why your choice of the data structure is well

justified. Several lines of customers should be displayed. You can add a new customer by pressing a

key. You’ll need to determine how the customer will decide which line to join. The checkers will

take random amounts of time to process each customer (presumably depending on how many

groceries the customer has.) Once checked out, the customer is removed from the line. For

simplicity, you may simulate the passing of time by pressing a key. Perhaps every key-press

indicates the passage of one minute. (Java may have more sophisticated ways to handle time.)

• Submit the source code that you have created to complete the assignment, but not the existing

library code (e.g., library code related to data structures and associated algorithms); specify the

origin of the library code you used (e.g., the textbook website) in the report

The report should also contain the text that explains and discusses your work:

1. It should be easily comprehensible to anyone who has taken a module on Data Structures

and Algorithms.

2. One of the main purposes is to convincingly demonstrate that you understand what you are

presenting.

3. It should be self-contained as much as possible and, thus, should contain the key code

fragments rather than merely referring to the submitted full source code.

4. Discuss any (potential) limitations or weakness of your work and how you would improve

if you have more time. Discussing the weakness would not negatively count towards your

mark. It is a recommended practice

JAVA PROGRAMMING LANGUAGE: Design and implement a class called Book that contains instance data for the title, author, publisher, and copyright date. Define the Book constructor to accept and initialize this data. Include setter and getter methods for all instance data. Include a toString method that returns a nicely formatted, multiline description of the book. Create a driver class called Bookshelf, whose main method instantiates and updates several Book objects.
