Answer:
d. d1− = 10, d1+ = 0
Explanation:
Given
3X1 + 4X2 +d1− − d1+ = 36
X1 = 6
X2 = 2
Required
Possible values of d1- and d1+
We have:
3X1 + 4X2 +d1− − d1+ = 36
Substitute values for X1 and X2
3 *6 + 4 * 2 + d1- - d1+ = 36
18 + 8 + d1- - d1+ = 36
Collect like terms
d1- - d1+ = 36 - 18 - 8
d1- - d1+ = 10
For the above equation to be true, the following inequality must be true
d1- > d1+
Hence,
(d) is correct
Because:
10 > 0

An alumnus (former student) has recently donated a large amount of money to your school. How do you think the funds should be spent? Create a multimedia presentation that can be used to convince school officials to use the money in the way you think is best for the school. " does anyone have a pdf file I could use to hand in I'll pay$
Answer:
It was a beautiful Monday morning at City Honors College Preparatory School. A student who graduated last year was making their way to the main office, and then after ten minutes they came out and that person gave me a smile. I went inside the office and I heard Mrs. Brown and Mrs. Wilson talking about a large amount of money that was donated to our school by an alumnus. It was a nice gesture from that person. Mrs. Brown said that they needed ways to think of how to use the money for the best of the school. I had a few ideas in mind.
Field trips would be a great way for us to make good use of the money donated by the alumnus. This can be a very educational and also a fun experience for all of us in school. This can help us learn new things. For example, if we go to a museum we can learn a lot about history which will help us understand it more if we have the class already. This will also give us an opportunity to socialize and interact with each other as we are being educated and having a fun time.
The money donated would greatly help us buy new school supplies. We are in need of new books and many more supplies. It would be nice for every teacher to have new supplies so they can be able to teach us the way we should be taught. In some cases, when I am in class the teacher has ran out of markers so we have to borrow one from another teacher. We could use the money to buy markers, pencils, pens, erasers, and any other school supplies we need. This money could help us buy more books so that every teacher has a class set and also a book for every student take home.
Every year, seniors have problems paying for their senior events such as prom, senior pictures, and grad night. The school can also use this money to help out the seniors. It would be such a good idea because it will help us save money from our pockets. Not only can it be used towards the seniors, but as well as for the underclassmen to help them pay for winter formal or for any other event that involves the whole school. It will help us all out and many more people will be able to attend the events. This will truly save money from our pockets that will help us out pay other important things that we might need in the future.
I really appreciate the person that made the donation to our school. They have given us a gift and it is something we will use wisely that will benefit our school, students and the teachers as well. The three ideas I proposed are adequate and I think they are the best ideas that we can follow as to how we should spend the money donated to our school. These are the ideas I have and the best ways to spend it for the convenience of our school, students, and the teachers.

Which of the following is NOT a feature of unclustered index
A. There can be several unclustered indexes on a data file
B. unclustered indexes are cheap to maintain and update
C. un Clustered index has the same ordering of data records as that of the data entries in the database
D. unClustered index has a different ordering of data records as that of the data entries in the database
Answer:
C. Unclustered index has the same ordering of data records as that of the data entries in the database
Explanation:
Indexes are used to split up queries in an SQL server or database management system DBMS.
There are two types of indexes namely clustered indexed and unclustered indexes.
Clustered indexes define the order in which data is stored in a table while unclustered index does not sort the order in a table.
In an unclustered index, the data table and the index are stored in different places, they are easy to maintain and update since they do not follow a particular order and there can be several indexes in a data file since the data table is stored differently from the index file.
So, all the other options except C are features of unclustered indexes since unclustered index does not have the same ordering of data records as that of the data entries in the database.
So, C is the answer.

Which of the following is true regarding the given code?
a. The error "Use of unassigned local variable a" will appear during compilation.
b. Line 4 will print the value of variable a as 2.
c. Line 6 will print the value of variable b as 2.
d. The error "Multiple declaration of the value variable" will occur during compilation.
Answer:
Use of unassigned local variable `a'
Explanation:
Required
What is true about the code
After declaring variable a as integer, i.e.
int a
For the program, a has to be initialized with an integer value
e.g. a = 5;
Initializing a will prevent the use of unassigned local variable error.
Since a is not initialized in the program, the program will return the above error for variable a.

Write a C program that uses a while statement to determine and print the largest of 10 numbers input by the user. Your program should use three variables, as follows: a) counter--A counter to count to 10 (i.e., to keep track of how many numbers have been input and to determine when all 10 numbers have been processed). by) number--The current number input to the program. c) largest--The largest number found so far.
Answer:
The program in C is as follows:
#include <limits.h>
#include <stdio.h>
int main(){
int count = 0;
int number, largest = INT_MIN;
while(count<10){
scanf("%d",&number);
if(number>largest){
largest = number; }
count++; }
printf("Largest: %d",largest);
return 0;
}
Explanation:
This initializes count to 0
int count = 0;
This declares number and largest; largest is also initialized to the smallest integer
int number, largest = INT_MIN;
This loop is repeated while count is less than 10
while(count<10){
Get each number
scanf("%d",&number);
If current input is greater than the largest integer, largest is updated to the current input
if(number>largest){
largest = number; }
Increase count by 1
count++; }
Print the largest
printf("Largest: %d",largest);

Write a program in Python representing 7 logic gates:
AND
NAND
OR
NOR
XOR
XNOR
NOT
Accept (only) two inputs to create all outputs.
Use the if statement to perform the Boolean logic.
Only accept numeric input.
If a number is greater than 0 treat it as a 1.
Specify in your output and in the beginning of the code (through print statements) which gate the code represents.
Comment your code.
Answer:
The program in python is as follows:
a = int(input("A: "))
b = int(input("B: "))
if a != 0:
a= 1
if b != 0:
b = 1
print("A AND B",end =" ")
if a == b == 1:
print("True")
else:
print("False")
print("A NAND B",end =" ")
if a == 0 or b == 0:
print("True")
else:
print("False")
print("A OR B",end =" ")
if a == 1 or b == 1:
print("True")
else:
print("False")
print("A NOR B",end =" ")
if a == 1 or b == 1:
print("False")
else:
print("True")
print("A XOR B",end =" ")
if a != b:
print("True")
else:
print("False")
print("A XNOR b",end =" ")
if a == b:
print("True")
else:
print("False")
print("NOT A",end =" ")
if a == 1:
print("False")
else:
print("True")
print("NOT B",end =" ")
if b == 1:
print("False")
else:
print("True")
Explanation:
These get inputs for A and B
a = int(input("A: "))
b = int(input("B: "))
a and b are set to 1 for all inputs other than 0
if a != 0:
a= 1
if b != 0:
b = 1
This prints the AND header
print("A AND B",end =" ")
AND is true if only A and B are 1
if a == b == 1:
print("True")
else:
print("False")
This prints the NAND header
print("A NAND B",end =" ")
NAND is true if one of A or B is 0
if a == 0 or b == 0:
print("True")
else:
print("False")
This prints the OR header
print("A OR B",end =" ")
OR is true if one of A or B is 1
if a == 1 or b == 1:
print("True")
else:
print("False")
This prints the NOR header
print("A NOR B",end =" ")
NOR is false if one of A or B is 1
if a == 1 or b == 1:
print("False")
else:
print("True")
This prints the XOR header
print("A XOR B",end =" ")
XOR is true if A and B are not equal
if a != b:
print("True")
else:
print("False")
This prints the XNOR header
print("A XNOR b",end =" ")
XNOR is true if a equals b
if a == b:
print("True")
else:
print("False")
This prints NOT header for A
print("NOT A",end =" ")
This prints the opposite of the input
if a == 1:
print("False")
else:
print("True")
This prints NOT header for B
print("NOT B",end =" ")
This prints the opposite of the input
if b == 1:
print("False")
else:
print("True")

Consider the following program in which the statements are in the incorrect order. Rearrange the statements so that the program prompts the user to input the height an the radius of the base of a cylinder and outputs the volume and surface area of the cylinder. Format the output to two decimal places.
#include
#include
int main()
{}
double height;
cout << "Volume of the cylinder = "
<< PI * pow(radius, 2.0)* height << endl;
cout << "Enter the height of the cylinder: ";
cin >> radius;
cout << endl;
return 0;
double radius;
cout << "Surface area: "
<< 2 * radius * + 2 * PI * pow(radius, 2.0) << endl;
cout << fixed << showpoint << setprecision(2);
cout << "Enter the radius of the base of the cylinder: ";
cin >> height;
cout << endl;
#include
const double PI = 3.14159;
using namespace std;
Answer:
The arrange code is as follows:
#include<iomanip>
#include<iostream>
#include<math.h>
using namespace std;
const double PI = 3.14159;
int main(){
double height;
double radius;
cout << "Enter the height of the cylinder: ";
cout << endl;
cin >> height;
cout << "Enter the radius of the base of the cylinder: ";
cout << endl;
cin >> radius;
cout << fixed << showpoint << setprecision(2);
cout << "Volume of the cylinder = "<< PI * pow(radius, 2.0)* height << endl;
cout << "Surface area: "<< 2 * radius * + 2 * PI * pow(radius, 2.0) << endl;
return 0;
}
Explanation:
Required
Rearrange the program
There are no one way to solve questions like this. However, a simple guide is as follows:
All header files must be called first (i.e #include....)
Followed by the namespaces (std)
if the program uses constant, the constant must be declared and initialized.
e.g. const double PI = 3.14159;
Next, all variables and must be declared (e.g. double radius)
Next, all inputs must be taken before the values of the variables can be used (e.g. cin >> height;)
If the inputs used prompts, the prompt must be before the inputs.
Next, perform all computations then output the results

All of the following are design elements of a landing page that instill trust in site visitors, except Group of answer choices secure payment methods social media presence large, clear, colorful action buttons visible contact information
Answer:
large, clear, colorful action buttons.
Explanation:
A website refers to the collective name used to describe series of web pages linked together with the same domain name while a webpage is the individual HTML document (single page) that makes up a website with a unique uniform resource locator (URL).
When users (people) visit a particular website (homepage, index page or landing page) for the first time, there are certain design elements that when seen would give them a sense of security, instill trust and guarantees confidentiality of all user data (informations).
Generally, secure payment methods, social media presence, and visible contact information are design elements of a landing page that instill trust in site visitors.
However, large, clear, and colorful action buttons wouldn't do or cause any of the aforementioned actions.
Write a program that first reads in the name of an input file and then reads the input file using the file.readlines() method. The input file contains an unsorted list of number of seasons followed by the corresponding TV show. Your program should put the contents of the input file into a dictionary where the number of seasons are the keys, and a list of TV shows are the values (since multiple shows could have the same number of seasons).
Sort the dictionary by key (least to greatest) and output the results to a file named output_keys.txt, separating multiple TV shows associated with the same key with a semicolon (;). Next, sort the dictionary by values (alphabetical order), and output the results to a file named output_titles.txt.
Ex: If the input is:
file1.txt
and the contents of file1.txt are:
20
Gunsmoke
30
The Simpsons
10
Will & Grace
14
Dallas
20
Law & Order
12
Murder, She Wrote
the file output_keys.txt should contain:
10: Will & Grace
12: Murder, She Wrote
14: Dallas
20: Gunsmoke; Law & Order
30: The Simpsons
and the file output_titles.txt should contain:
Dallas
Gunsmoke
Law & Order
Murder, She Wrote
The Simpsons
Will & Grace
Note: There is a newline at the end of each output file, and file1.txt is available to download.
currently, my code is:
def readFile(filename):
dict = {}
with open(filename, 'r') as infile:
lines = infile.readlines()
for index in range(0, len(lines) - 1, 2):
if lines[index].strip()=='':continue
count = int(lines[index].strip())
name = lines[index + 1].strip()
if count in dict.keys():
name_list = dict.get(count)
name_list.append(name)
name_list.sort()
else:
dict[count] = [name]
return dict
def output_keys(dict, filename):
with open(filename,'w+') as outfile:
for key in sorted(dict.keys()):
outfile.write('{}: {}\n'.format(key,';'.join(dict.get(key))))
print('{}: {}\n'.format(key,';'.join(dict.get(key))))
def output_titles(dict, filename):
titles = []
for title in dict.values():
titles.extend(title)
with open(filename,'w+') as outfile:
for title in sorted(titles):
outfile.write('{}\n'.format(title))
