Answer: it is the code it is wrong
Explanation:
In this program we are going to practice using the Math class by computing some important values on the unit circle. Starting at 0 and going up by
PI/4 radians (or 45 degrees), print out information of the format below.
Radians: (cos, sin)
0.0: 1.0, 0.0
0.79: 0.7, 0.71
1.57: 0.0, 1.0
2.36: -0.71, 0.7
3.14: -1.0, 0.0
3.93: -0.7, -0.71
4.71: 0.0, -1.0
5.5: 0.71, -0.71
Hints:
You’ll need to use the Math.sin, Math.cos methods
and the Math.PI constant!
You’ll also need to loop from 0 to 2*PI
You can round a decimal to 2 decimal places by multiplying by 100, rounding to the nearest int, and then dividing by 100. Here’s an example:
double value = 0.431675;
value = value * 100; // 43.1675
value = Math.round(value) // 43.0
value = value / 100.0; // 0.43
// Or put it all on one line:
value = Math.round(value * 100) / 100.0;
Answer:
The program in Java is:
import java.lang.*;
public class MyClass {
public static void main(String args[]) {
for(int i= 0;i<360;i+=45){
double angle = Math.round(Math.toRadians(i)*100.0)/100.0;
double cosX = Math.round(Math.cos(angle)*100.0)/100.0;
double sinX = Math.round(Math.sin(angle)*100.0)/100.0;
System.out.println(angle+": "+cosX +" "+ sinX);
}
}
}
Explanation:
This line iterates through the angles from 0 to 360 or 0 to 2*Pi
for(int i= 0;i<360;i+=45){
This calculates the angle to radians
double angle = Math.round(Math.toRadians(i)*100.0)/100.0;
This calculats the cosine of the angle rounded to 2 decimal place
double cosX = Math.round(Math.cos(angle)*100.0)/100.0;
This calculats the sine of the angle rounded to 2 decimal place
double sinX = Math.round(Math.sin(angle)*100.0)/100.0;
This prints the required output
System.out.println(angle+": "+cosX +" "+ sinX);
}
An administrator edits the network firewall configuration. After editing the configuration, the administrator logs the date and time of the edit and why it was performed in the firewall documentation. Which of the following BEST describes these actions?
a. Asset management
b. Baselines
c. Network maps
d. Change management
Answer:
d. Change management
Explanation:
Change management can be defined as a strategic process which typically involves implementing changes (modifications) to an existing process or elements on a computer system.
In this scenario, an administrator edits the network firewall configuration. After editing the configuration, the administrator logs the date and time of the edit and why it was performed in the firewall documentation. Thus, what best describes these actions is change management.
As a network administrator, you would be required to perform changes to your network and network devices in order to get an optimum level of performance.
Do you think it’s better for a young designer to use free, open-source art programs or to pay for commercial programs? Explain your answer, but come up with at least one counterargument that forces you to defend your position when you explain why you think one option is better than the other.
Answer:
I think that if you are starting you should use a free, open-source art program. Because starting up with alot of things like this is hard with no money but the resources that we have could help with that. That's why I think the free one is better than paying, especially monthly pay.
Explanation:
The divBySum method is intended to return the sum of all the elements in the int array parameter arr that are divisible by the int parameter num. Consider the following examples, in which the array arrcontains {4, 1, 3, 6, 2, 9}.
The call divBySum(arr, 3) will return 18, which is the sum of 3, 6, and 9, since those are the only integers in arr that are divisible by 3.
The call divBySum(arr, 5) will return 0, since none of the integers in arr are divisible by 5.
Complete the divBySum method using an enhanced for loop. Assume that arr is properly declared and initialized. The method must use an enhanced for loop to earn full credit.
/** Returns the sum of all integers in arr that are divisible by num
* Precondition: num > 0
*/
public static int divBySum(int[] arr, int num)
Answer:
The complete method is as follows:
public static int divBySum(int[] arr, int num){
int sum = 0;
for(int i:arr){
if(i%num == 0)
sum+=i;
}
return sum;
}
Explanation:
As instructed, the program assumes that arr has been declared and initialized. So, this solution only completes the divBySum method (the main method is not included)
This line defines the method
public static int divBySum(int[] arr, int num){
This line declares and initializes sum to 0
int sum = 0;
This uses for each to iterate through the array elements
for(int i:arr){
This checks if an array element is divisible by num (the second parameter)
if(i%num == 0)
If yes, sum is updated
sum+=i;
}
This returns the calculated sum
return sum;
}

Write a program that reads an integer between o and 1000 and adds all the digits in the integer. For example, if an integer is 932, the sum of all the digits is 14. Hint: Use the % operator to extract digits, and use the / operator to remove the extracted digit. For instance, 932 % 10=2 and 932/10 =93. Here is a sample run:
Enter a number between 0 and 1000 : 999
The sum of digits is 27.
Answer:
Answered below
Explanation:
#Program is written in Python programming language
digit = 0
sum = 0
num = int(input("Enter a number between 0 and 1000: ")
#Check that number is within the valid range
if num > 0 and num <= 1000:
while num != 0:
#Isolate each digit
digit = num % 10
sum = sum + digit
#Remove isolated digit from number
num = num/10
else:
print("Number is not within valid range")
#print total sum of digits
print(sum)

CSc 2720 - Data Structures: Assignment 1 [100 points] How to Submit: Turn the .java file in Folder Assignment 1 in iCollege no later than 11:00 p.m. ET on 01/27/2021 Notes: 1. Do not use any library for matrix multiplication. 2. Always use comments to explain your program. 3. No copying allowed. If it is found that students copy from each other, all of these programs will get 0. 4. You must use matrix.java as the program name; otherwise, you will lose 10%. Requirements: You are to write a program name matrix.java that makes the dot products of 2 arrays. 1. Your program should prompt the user for the dimensions of the two squares matrices, making sure that the user input is equal to 50. 2. If the above is not met, prompt the user for a new value. 3. Now generate random integer numbers (ranging from 0 to 50) to fill both matrices. 4. Display these two matrices on the screen. 5. Multiply the two matrices and display the result on the screen. 6. Insert a clock to see how long it would take to multiply these two matrices and display the time (with a message to this effect). 7. Prompt the user asking if they want to repeat the program. A simple example of program output (here matrix dimension is 4, your should be 50):
A drink costs 2 dollars. A taco costs 3 dollars. Given the number of each, compute total cost and assign totalCost with the result. Ex: 4 drinks and 6 tacos yields totalCost of 26.
*/
int main() {
int numDrinks = 0;
int numTacos = 0;
int totalCost = 0;
numDrinks = 4;
numTacos = 6;
/* Your solution goes here */
totalCost = (2 * numDrinks) + (3 * numTacos);
cout << "Total cost: " << totalCost << endl;
return 0;
}
Answer:
See Explanation
Explanation:
The question has been answered; however, the program is not dynamic enough because the output will always be 26.
To make it dynamic, replace the following lines of code:
numDrinks = 4;
numTacos = 6;
with:
cout<<"Number of drinks: ";
cin>>numDrinks;
cout<<"Number of Tacos: ";
cin>>numTacos;
The above lines of code will let the user input different values for numDrinks and numTacos each time the program is executed.
Computing the total cost using code can be represented as follows:
def total_cost(no_of_drinks, no_of_talcos):
totalCost = 2*no_of_drinks + 3*no_of_talcos
return totalCost
print(total_cost(4, 6))
Python code explanation:A function named total_cost is declared and it accept the parameters no_of_drinks and no_of_talcos.
The totalCost is used to store the result of the cost of the total drinks and tacos bought in dollars.
Then, we return the totalCost.
Finally, we use the print statement to call the function with its required parameters.

var nums = [1,1, 2, 3, 5, 8, 13, 21];
var copyNums = [1,1, 2, 3, 5, 8, 13, 21];
for(var i=0; i < copyNums.length; i++){
if(copyNums[i] == 1){
insertItem(copyNums,i,"hello");
}
}
This code will create an infinite loop. Why does it create an infinite loop?
Answer:
Explanation:
This code creates an infinite loop because it is detecting that the first value of copyNums is 1, therefore it runs the insertItem code. This code then adds the value "hello" to the array in position i which would be 0. Then moves to the next value of the array, but since the element "hello" pushed the value 1 to the next index then the code just repeats itself with the same value of 1. This continues to happen because every time the value "hello" is added it simply pushes the 1 to the next index and repeats the same code.
Answer:
[tex]var nums = [1,1, 2, 3, 5, 8, 13, 21];
var copyNums = [1,1, 2, 3, 5, 8, 13, 21];
for(var i=0; i < copyNums.length; i++){
if(copyNums[i] == 1){
insertItem(copyNums,i,"hello");
}

Consider the following method, inCommon, which takes two Integer ArrayList parameters. The method returns true if the same integer value appears in both lists at least one time, and false otherwise.
public static boolean inCommon(ArrayList a, ArrayList b)
{
for (int i = 0; i < a.size(); i++)
{
for (int j = 0; j < b.size(); j++) // Line 5
{
if (a.get(i).equals(b.get(j)))
{
return true;
}
}
}
return false;
}
Which of the following best explains the impact to the inCommon method when line 5 is replaced by for (int j = b.size() - 1; j > 0; j--) ?
A. The change has no impact on the behavior of the method.
B. After the change, the method will never check the first element in list b.
C. After the change, the method will never check the last element in list b.
D. After the change, the method will never check the first and the last elements in list b.
E. The change will cause the method to throw an IndexOutOfBounds exception.
Answer:
The answer is "Option b".
Explanation:
In the given code, a static method "inCommon" is declared, that accepts two array lists in its parameter, and inside the method two for loop is used, in which a conditional statement used, that checks element of array list a is equal to the element of array list b. If the condition is true it will return the value true, and if the condition is not true, it will return a false value. In this, the second loop is not used because j>0 so will never check the element of the first element.
