Answer:
tryagain = "Y"
while tryagain.upper() == "Y":
x1 = int(input("x1: "))
y1 = int(input("y1: "))
x2 = int(input("x2: "))
y2 = int(input("y2: "))
x3 = int(input("x3: "))
y3 = int(input("y3: "))
area = abs(x1 *(y2 - y3) + x2 * (y1 - y3) + x3 * (y1 - y2))
if area > 0:
print("Inputs form a triangle")
else:
print("Inputs do not form a triangle")
tryagain = input("Press Y/y to try again: ")
Explanation:
To do this we simply calculate the area of the triangle given that inputs are on plane coordinates i.e. (x,y).
If the area is greater than 0, then it's a triangle
If otherwise, then it's not a triangle.
This line initializes iterating variable tryagain to Y
tryagain = "Y"
while tryagain.upper() == "Y":
The following lines get the coordinates of the triangle
x1 = int(input("x1: "))
y1 = int(input("y1: "))
x2 = int(input("x2: "))
y2 = int(input("y2: "))
x3 = int(input("x3: "))
y3 = int(input("y3: "))
This calculates the area
area = abs(x1 *(y2 - y3) + x2 * (y1 - y3) + x3 * (y1 - y2))
This checks for the condition stated above.
if area > 0:
print("Inputs form a triangle") This is printed, if true
else:
print("Inputs do not form a triangle") This is printed, if otherwise
tryagain = input("Press Y/y to try again: ") This prompts the user to try again with another set of inputs
Give a recursive definition of the set of positive integer powers of 3.That is the set {3,9,27,81,...}
Answer:
We have set A,
3 ∈ S
n*3 if n ∈ S
Explanation:
A recursion can be defined as a way of defining objects in terms of itself or as parts of itself.
Lets say we a set that is defined as A,
Then the recursive definition of the sets of positive integers with the powers of 3 in A is given as
3 ∈ S
n*3 if n ∈ S
This tells us that 3 is an element of S such that if n is an element of S then in general we would have n*3 to be an element of S
A software developer is creating a variable to hold whole numbers and will perform numeric operations on the values stored in that

A technology that can help a student to increase his or her understanding of the vocabulary used in a classroom is called:_______
a. assistive instruction.
b. UDL technology.
c. hypertext software.
d. adaptive instruction.
Answer:
c. hypertext software.
Explanation:
In Computer science, a hypertext can be defined as textual informations that are being displayed on a computer system and these texts usually links to other informations (texts) that the user can easily have access to in real-time.
Basically, some developers include encyclopedias and dictionaries in their software database, which makes other necessary informations or contents easier and immediately accessible to the users through the use of hypertexts that is activated by pointing and clicking on the link with a mouse, keypress set or soft touching the screen.
Hence, a technology that can help a student to increase his or her understanding of the vocabulary used in a classroom is called hypertext software.
. Write and execute a query that will determine the average age of customers broken out by the city in which they reside. Note: Make sure that the average age is not truncated to an integer.
Answer:
SELECT resid_city, avg(convert(float,age))
FROM customer
GROUP BY resid_city
Explanation:
SQL or structured query language is a language used to interact with databases. It is a relational database language, used to create, update, and query the content of databases.
The "SELECT" clause in the query statement above is used to read the content of the customer table querying the table based on the average age of customers grouped by their resident cities to return the "resid_city" and the float number of the average age.
Display the order date and the ship date for all orders that were made April 1 through April 15. List the order date, ship date, order priority, and ship mode. Order the results by order_date. Do you notice anything unusual about the data? [Hint: You will need to join the orders and shipping together and use a join statement. You will need to limit the result set by the date field order_date <= to_date('04/15/2018', 'mm/dd/yyyy')This is what I was able to come up with but it still gave me an error.select orders.order_date, shipping.ship_date, orders.order_priority, shipping.ship_modefrom ordersinner join shipping on orders.order_date = shipping.ship_datewhere Orders.Order_date = Shipping.ship_date AND Order_Date BETWEEN TO_DATE (’04/01/2018’, ‘04/15/2018’)ORDER BY Order_Date;
Answer:
SELECT Order_date, Ship_Date, Order_priority, Ship_mode
FROM orders
JOIN Shipping ON Orders.Order_id = Shipping.Order_id
WHERE Order_date
BETWEEN TO_DATE('04/01/2018', '%m/%d/%Y') AND TO_DATE('04/15/2018', '%m/%d/%Y')
ORDER BY Order_date
Explanation:
The SQL statement above queries a database with four tables shipping, orders, market and product. The query returns four columns from two tables orders and shipping, returning only rows with order dates between April 1 and April 15 of 2018. The tables are joined with the primary key order_id and the dates are parsed with the to_date function. The result is also ordered by the order_date
Define bit byte and word
Explanation:
Definitions. Bit = Binary digIT = 0 or 1. Byte = a sequence of 8 bits = 00000000, 00000001, ..., or 11111111. Word = a sequence of N bits where N = 16, 32, 64 depending on the compute
Mad Libs are activities that have a person provide various words, which are then used to complete a short story in unexpected (and hopefully funny) ways. Complete the program to read the needed values from input, that the existing output statement(s) can use to output a short story. Ex: If the input is: Eric Chipotle 12 cars
Answer:
statement = input("Enter four words separated by a space: ")
split_list = statement.split(" ")
print(f"{split_list[0]} went to {split_list[1]} to buy {split_list[2]} different types of {split_list[3]}")
Explanation:
The python program uses the input function to get user input from the STDIN and the words gotten are splitted to a list, then the items of the list are used as part of a sentence.
Answer:
Playing around with this and came up with this, it took about an hour before I understood what it was wanting.

Write a Python program that uses function(s) for writing to and reading from a file:
a. Random Number File Writer Function
Write a function that writes a series of random numbers to a file called "random.txt". Each random number should be in the range of 1 through 500. The function should take an argument that tells it how many random numbers to write to the file.
b. Random Number File Reader Function
Write another function that reads the random numbers from the file "random.txt", displays the numbers, then displays the following data:
The total of the numbers
The number of random numbers read from the file
c. Main Function
Write a main function that asks the user about how many random number the user wants to generate. It them calls the function in a. with the number the user wants as an argument and generates random numbers to write to the file. Next, it calls the function in b.
import random
def random_number_file_writer(nums):
f = open("random.txt", "w")
i = 0
while i < nums:
f.write(str(random.randint(1,500))+"\n")
i += 1
f.close()
def random_number_file_reader():
f = open("random.txt", "r")
total = 0
count = 0
for x in f.readlines():
total += int(x)
count += 1
print("The total of the numbers is "+str(total))
print("The number of random numbers read from the file is "+str(count))
def main():

1. Write a high level algorithm for cooking a cheeseburger.
2. Write a detailed algorithm for cooking the same cheeseburger.
Answer:
1. A high level algorithm for cooking a cheeseburger could be:
Heat fry panCook one side of the hamburgerWaitTurn hamburger upside downPut cheese over hamburgerWaitCut hamburger bread in halfPut cooked hamburger inside breadEnd (eat)2. A detailed algorithm for cooking a cheeseburger could be:
Place fry pan over the stove heaterTurn on heater (max temp)IF fry pan not hot: wait, else continuePlace raw hamburger on fry panIF hamburger not half cooked: Wait X time then go to line 5, else continueTurn hamburger upside downPut N slices of cheese over hamburgerIF hamburger not fully cooked: Wait X time then go to line 8, else continueTurn off heaterCut hamburger bread in half horizontally Put cooked hamburger on one of the bread halves.Put second bread half on top of hamburgerEnd (eat)Explanation:
An algorithm is simply a list of steps to perform a defined action.
On 1, we described the most relevant steps to cook a simple cheeseburger.
Then on point 2, the same steps were taken and expanded with more detailed steps and conditions required to continue executing the following steps.
In computational terms, we used pseudo-code for the algorithm, since this is a list of actions not specific to any programming language.
Also we can say this is a structured programming example due to the sequential nature of the cooking process.
If a machine cycle is 2 nanoseconds , how many machine cycles occur each second?
Answer: 5 × 10^8 cycles per second
Explanation:
First and foremost, we should note that 1 nanosecond = 1 × 10^-9 seconds
We are told that the machine cycle is 2 nanoseconds.
The number of machine cycles that occur each second will them be calculated as:
1 = 2 × 10^-9
= 5 × 10^8 cycles per second
The number of machine cycles that occur each second is 5 × 10^8 cycles per second.
If a system's instruction set consists of an 8-bit opcode, what is the maximum number of output signal lines required for the control unit?
A) 8 B) 64C) 128 D) 256
Answer:
D. 256
Explanation:
Given
[tex]Instructions = 8\ bit[/tex]
Required
Determine the maximum number of output
To get the required value, we make use of the following:
[tex]Maximum = 2^n[/tex]
Where n is the bits of the opcode.
i.e.
[tex]n = 8[/tex]
Substitute 8 for n in [tex]Maximum = 2^n[/tex]
[tex]Maximum = 2^8[/tex]
[tex]Maximum = 256[/tex]

Edhesive Intro to CS Code Practice 1.8
I am pretty sure I got it right. But it keeps telling me that I have an EOF error on the E input.
Questions:
CS Code Practice 1.8 Question 1:
Write a code that accepts the user's age as an input, then print their age in 10 years.
CS Code Practice 1.8 Question 2:
Write a code that accepts a whole number as an input, subtracts 5 and print the answer
Answer:
Question 1:
currentage = int(input("Enter your age: "))
print("Your age in 10 years is "+str(currentage + 10))
Question 2:
userinput = int(input("Enter a whole number: "))
print(str(userinput)+" - "+str(5)+" = "+str(userinput - 5))
Explanation:
There are two questions in this category and I don't know which of them you need; So, I answered both.
Question 1:
This line prompts user for age
currentage = int(input("Enter your age: "))
This line adds 10 to user input and prints the result
print("Your age in 10 years is "+str(currentage + 10))
Question 2:
This line prompts user for a whole number
userinput = int(input("Enter a whole number: "))
This line subtracts 5 from the whole number and prints the result
print(str(userinput)+" - "+str(5)+" = "+str(userinput - 5))

5.14 Describe how the compare and swap() instruction can be used to provide mutual exclusion that satisfies the bounded-waiting requirement. (15 pts)
Answer:
Explained below
Explanation:
Compare and Swap(C&S) is simply an atomic operation whereby the compare and swap operations are automatically executed.
Now compare and Swap basically needs 3 arguments namely:
- 2 old values which we will label X and Y
- 1 new value which is written in X that we will call Z
Thus, we now have; C & S = {X, Y, Z}
To explain this well, let X be a variable where X has a value of 7.
Now, if a programmer gives a program me that X be multiplied by 2,then what C&S operation will do is;
I) Y = X where Y is a new variable.
II) Result = C&S(X, Y, X*7)
Variable X is global and this means that mere than one process and more than 1 thread can see the variable X.
Now, if a process named P1 wants multiply the variable X by 7 using C&S operation, it will first make a local copy of variable X (which in this case is now the new variable Y). After that it will atomically compare X & Y and if they are equal, it will replace X with 10X.
However, if they are not equal, P1 will re-read value of X into Y and carry of C&S instruction again.

Answer:
The static n variable is incremented twice and the results printed in the console but the output of the x variable remains constant.
Explanation:
The while loop in the C++ source code increments the n variable as the argument of the function "a" is decremented. The n variable output is 0,1, and 2 while the x variable is 0 for every iteration.
