Q No. 2: Draw a Use Case diagram for "The Pizza Ordering System". (Hint – correct <> or <> relationships will attract additional marks). The Pizza Ordering System The Pizza Ordering System allows the user of a web browser to order pizza for home delivery. To place an order, a shopper searches to find items to purchase, adds items one at a time to a shopping cart, and possibly searches again for more items. When all items have been chosen, the shopper provides a delivery address. If not paying with cash, the shopper also provides credit card information. The system has an option for shoppers to register with the pizza shop. They can then save their name and address information, so that they do not have to enter this information every time that they place an order.

Let l(x) be "x has an internet conection" and C(x, y) be "x and y have chatted over the internet". Assume the domain is all students in a class. Express the following using quantifiers. 1. Jerry does not have an internet connection 2. Exactly one student in the class has an internet connection 3. Someone in your class has an internet connection but has not chatted with anyone else in the class.
A) quadrant [★★] Complete the quadrant function below, which should return the quadrant of the given x, y point according to the diagram on the right (borrowed from Wikipedia). Points that lie on an axis do not belong to any quandrant. Hints: (a) define a helper function for the sign of an integer, (b) match against a pair. type quad = I | II | III | IV type sign = Neg | Zero | Pos let sign (x:int) : sign = ... let quadrant : int*int -> quad option = fun (x,y) -> match ... with | ... -> Some I | ... -> Some II | ... -> Some III | ... -> Some IV | ... -> None B) quadrant when [★★] Rewrite the quadrant function to use the when syntax. You won’t need your helper function from before. let quadrant_when : int*int -> quad option = function | ... when ... -> Some I | ... when ... -> Some II | ... when ... -> Some III | ... when ... -> Some IV | ... -> None please use Ocaml for the code
"Equatable and Comparable" in the Swift Programming: The Big Nerd Ranch Guide (2nd Ed.) e-book: Point’s current conformance to Comparable yields some confusing results. let c = Point(x: 3, y: 4) let d = Point(x: 2, y: 5) let cGreaterThanD = (c > d) // false let cLessThanD = (c < d) // false let cEqualToD = (c == d) // false As the above example demonstrates, the trouble arises in comparing two points when one point’s x and y properties are not both larger than the other point’s. In actuality, it is not reasonable to compare two points in this manner. Fix this problem by changing Point’s conformance to Comparable. Calculate each point’s Euclidean distance from the origin instead of comparing x and y values. This implementation should return true for a < b when a is closer to the origin than b. Use the formula shown in below Figure 25.1 to calculate a point’s Euclidean distance. Figure 25.1 Euclidean distance Euclidean distance
Solve the problems below. Copy the description of your Ferris wheel in the text box and include that as part of your initial Discussion post in Brightspace. Using "copy" from here in Mobius and "paste" into Brightspace should work. Hint: This is similar to Question 48 in Section 8.1 of our textbook. We covered this section in "5-1 Reading and Participation Activities: Graphs of the Sine and Cosine Functions" in Module Five. You can check your answers to part a and c to make sure that you are on the right track. A Ferris wheel is 30 meters in diameter and completes 1 full revolution in 8 minutes. A Ferris wheel is 30 meters in diameter and boarded from a platform that is 1 meter above the ground. The six o’clock position on the Ferris wheel is level with the loading platform. The wheel completes 1 full revolution in 8 minutes. The function h(t)ht gives a person’s height in meters above the ground tt minutes after the wheel begins to turn. a. Find the amplitude, midline, and…

Create a UML class diagram for the following problem: The McDonald’s company has several restaurants in Budapest. Each restaurant has a unique ID and an address. They sell cheeseburger for 500 HUF, BigMac for 1000 HUF, and Chicken McNuggets for 800 HUF. All three can be ordered alone or in small, medium, or large menu. The different menus mean French fries and drink in addition. The small menu costs 500 HUF, the medium is 700 HUF, and the large is 1000 HUF in addition. The customers get a loyalty card from the McDonald’s company which has a unique number. Based on the card, it can be got what kind of foods were ordered by that guest in the different restaurants. Make it possible to populate this problem: create methods to add new restaurant, customer, loyalty card, and orders related to any of the cards.Is it true that each restaurant of the company has a guest who has spent more than 10000 HUF?How much has a guest spent in a given restaurant?How many guests have spent more than 10000…
Question 4 This question assesses Block 2 Part 4. Parts a and b of this question involve creating drawings or descriptions. You can make your drawings whichever way is easiest or fastest for you. For instance, you could simply make your drawings using pencil and paper then scan or photograph them. Alternatively, you can answer by providing descriptions of the drawings. In that case, keep close to the formulations used in the long figure descriptions of the examples given in Section 4.5 of Block 2 Part 4. a.Consider the following lines entered on the Python shell: >>> Q4_TMA02 = 'submitted' >>> id(Q4_TMA02) 1944127298928 >>> type(Q4_TMA02) >>> Q4_TMA02 'submitted' Draw (or describe) the object and its label that the Python interpreter creates in response to the assignment Q4_TMA02 = 'submitted' in the interactive shell above. Your drawing or description should include a String object with a similar level of detail as Figure 4.14 in…

Create the abstract use case for business manager of Amazon to find the top 10 popular items in search and purchase for the past week for a given region. Then, create the corresponding business use case. In the case above "Generate Reports" would be the business use case, " generate popular items" would be the abstract use case. It can only be accessed after the decision to generate a report. In the case of the question above the actor is specified as a business manger therefore generate popular items is an include. If the actor were simply an employee it is an extend because it is conditional on employee type.
