Answer:
a² + 1/a² = 7
Explanation:
a + 1/a = 3 ; obtain the value of a² + 1/a²
Taking a + 1/a = 3
Squaring both sides ;
(a + 1/a)² = 3²
(a + 1/a)(a + 1/a) = a² + a/a + a/a + 1/a² = 3²
(a + 1/a)(a + 1/a) = a² + 1 + 1 + 1/a² = 9
a² + 2 + 1/a² = 9
a² + 1/a² = 9 - 2
a² + 1/a² = 7
Hence,
a² + 1/a² = 7

Write a program Ticket.py that will allow the user to enter actual speed
limit, the speed limit at which the offender was travelling, and the number
of previous tickets that person has received. The application should
calculate and display how many miles over the speed limit the offender
was travelling, the cost of the speeding ticket, and court cost. Use $10.00
as the amount to be charged for each mile per hour over the speed limit.
The court cost should be $50.00
Answer:
Following are the code to the given question:
def speedlimit():#defining a method speedlimit
a= int(input("Enter the offender's speed in mph: "))#defining a variable for input value
lim = int(input("Enter the speed limit in mph: "))#defining a variable for input value
n = int(input("The number of previous tickets that person has received: "))#defining a variable for input value
if (lim >= 20) and (lim < 70):#defining if block to check speed is between 20 to 70
if a > lim:#use if to check lim value greater than a
print("Driver was going", a-lim, "mph over the limit.")#print calculated value with message
print("The cost of the speeding ticket $",10*(a-lim))#print calculated value with message
else:
print( "Driver was going at a legal speed.")#print message
else:
print('Invalid speed limit.')#print calculated value with message
print("Court cost $",(50 + n*20))#print calculated value with message
speedlimit()
Output:
Please find the attached file.
Explanation:
In this code, a method "speedlimit" is declared that defines three variables that are "a, lim, and n" in which we input value from the user-end.
Inside the method, a nested conditional statement is used that checks the speed value is between 20 to 70 if it is true it will go to the next condition in which it checks lim value greater than a. It will use a print message that will print the calculated value with the message.

Discuss at least 1 Microsoft Windows security features that could protect data?
Answer:
Virus & threat protection.
Explanation:
Monitor threats to your device, run scans, and get updates to help detect the latest threats.
One Microsoft Windows security feature that can help protect data is BitLocker Drive Encryption.
BitLocker is a full-disk encryption feature available in certain editions of Microsoft Windows, such as Windows 10 Pro and Enterprise. It provides protection for data stored on the system's hard drives or other storage devices.
By encrypting the entire drive, BitLocker helps safeguard the data against unauthorized access or theft, even if the physical drive is removed from the device. It uses strong encryption algorithms to convert the data into an unreadable format, ensuring that only authorized users with the appropriate encryption key or password can access and decrypt the data.
BitLocker also provides additional security features, such as pre-boot authentication, which requires users to enter a password or use a USB key to unlock the drive before the operating system loads. This prevents unauthorized users from accessing the encrypted data, even if they have physical access to the device.
Overall, BitLocker Drive Encryption is a powerful security feature in Microsoft Windows that can effectively protect data by encrypting entire drives and adding layers of authentication and protection against unauthorized access.

After a worksheet has been completed, the statement columns contain all data that are required for the preparation of financial statements. True False
Answer:
True
Explanation:
Financial statements can be defined as a document used for the formal communication or disclosure of financial information and statements to present and potential users such as investors and creditors. Thus, a financial statement includes balance sheet, statement of retained earnings and income statement.
A worksheet comprises of a multiple-column form that is used by accountants or auditors for an adjustment process and the preparation of a financial statement. A worksheet contains the following columns; trial balance, adjusted trial balance, adjustments, balance sheet and income statement.
After a worksheet or spreadsheet document has been completed, a financial expert such as an accountant inputs into the statement columns all the data that are required for the preparation of financial statements.
Write a method, findMax(), that takes in two integers and returns the largest value. Ex: If the program input is: 4 2 the method findMax() returns: 4 Note: Your program must define the method: public int findMax(int num1, int num2)
public int findMax(int num1, int num2){
if(num1 > num2){
return num1;
}
else {
return num2;
}
}
Explanation:The code has been written in Java and the following explains every part of the code.
i. Start with the method header:
public int findMax(int num1, int num2)
ii. Followed by a pair of curly braces representing the block for the method.
public int findMax(int num1, int num2){
}
iii. Within the block, write the statements to find out which is greater between num1 and num2
This is done with an if..else statement. To check if num1 is greater than num2, write the following within the block.
if(num1 > num2){
return num1;
}
else {
return num2;
}
The if block tests if num1 is greater than num2. If it is, then num1 will be returned.
The else block is executed only if num1 is not greater than num2. In this case, num2 will be returned since it is greater.
iv. Put all together
public int findMax(int num1, int num2){
if(num1 > num2){
return num1;
}
else {
return num2;
}
}

For this activity, you will practice being both proactive and reactive to bugs. Both are necessary to get rid of errors in code.
Proactive:
Log in to REPL.it and open your Calculator program that you built in Unit 5.
In the index.js file, type and finish the following block of code that validates the input to make sure both are numbers (not letters or symbols):
try{
if (isNaN(…) || isNaN(…)){
throw …
}
else{
document.getElementById("answer").innerHTML = num1 + num2;
}
}
catch(e){
document.getElementById("answer")…
}
(Note: The || symbol is used in JavaScript to mean or . You can find this key to the left of the Z key if you’re using a PC or directly above the Enter key if you’re using a Mac.)
Add the finished code above to the correct place in your add() function. Make sure to delete this line since we moved it into the try block:
document.getElementById("answer").innerHTML = num1 + num2;
Paste the same code into the subtract() , multiply() , and divide() functions, making the necessary changes. Be careful with your divide() function since you already have an extra if else statement checking for a division by 0 mistake. (Hint: Cut and paste the entire if else statement inside the else block of your try statement.)
Test your program by typing in letters or symbols instead of numbers. Make sure you get the appropriate error message. (Note: The function is not supposed to check whether the text field is empty, only whether it contains non-numbers.)
When you are finished, share the link to your webpage with your teacher by clicking on the share button and copying the link.
Reactive:

What help in executing commands quickly
Answer:99
Explanation: Last summer, my family and I took a trip to Jamaica. My favorite part of the trip was when we went to a place called the Luminous Lagoon. We ate dinner and waited for the sun to go down. Then we boarded a boat and went out into the lagoon. That’s when the magic started.
At first we could not see very much in the darkness except for the stars in the sky. After a few minutes, however, I noticed some fish swimming in the water. They didn’t look like ordinary fish. These fish were glowing! Our guide explained that the glow came from tiny creatures in the water called dinoflagellates. These little animals are not visible to us, but their bodies produce light using something called bioluminescence, just like fireflies. There are so many of these creatures in Luminous Lagoon that the water around them seems to glow.
After our guide explained these facts to us, he told us to put our hands in the water. I was not sure if it would work, but I tried it. When I did, my hand looked like it belonged to a superhero! It was glowing bright blue. I hope someday I get to return to the Luminous Lagoon. The lights in the water were much more entertaining than the ones in the sky.
Problem:

(CO 4 and 5) Create a program that will read in a list of test scores from the user and add them to a list. Ask the user in between each score if they want to continue (y/n). Display all of the scores entered and the total score at the end. Using the code below, put the code in the proper order Sample output: Welcome to the Test Score Program Add score: 88.45 Do you want to continue
Answer and Explanation:
Using Javascript:
function AddScores(){
Window.alert("Welcome to the Test Score Program");
var ScoreList= new Array();
ScoreList.push(Prompt("Add Score"));
var WhatNext= Confirm("do you want to continue?");
If(WhatNext===true) {
do{
ScoreList.push(Prompt("Add Score"));
}
While(
Confirm("do you want to continue?")===true;);
}
Alert(ScoreList);
Alert(ScoreList.reduce(function(a,b){return a +b};,0);)
}
AddScores();
From the above code in javascript programming language, we have created a list ScoreList and added elements to it using push method of the array object and a do...while loop that checks the condition and then adds the user's input to the array. We then alerted the array to the screen and then summed up the array elements and also alerted to the screen.
