Answer:
Explanation:
The following is written in Java. The MilesToLaps method creates a variable called laps and gives it the value of the input parameter miles divided by 0.25. Then it returns the variable laps to the user. In the main method a Scanner object was created and asks the user for the number of miles which are passed to the MilesToLaps method which returns the number of laps. This can be seen in the attached image below.
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("How many miles?");
float miles = in.nextFloat();
System.out.println("This is " + MilesToLaps(miles) + " laps");
}
public static float MilesToLaps(float miles) {
float laps = (float) (miles / 0.25);
return laps;
}

Compute the acceleration of gravity for a given distance from the earth's center, distCenter, assigning the result to accelGravity. The expression for the acceleration of gravity is: (G * M) / (d2), where G is the gravitational constant 6.673 x 10-11, M is the mass of the earth 5.98 x 1024 (in kg) and d is the distance in meters from the earth's center (stored in variable distCenter).
#include
using namespace std;
int main() {
double G = 6.673e-11;
double M = 5.98e24;
double accelGravity;
double distCenter;
cin >> distCenter;
/* Your solution goes here */
cout << accelGravity << endl;
return 0;
}
Answer:
Replace /* Your solution goes here */ with the following expression
accelGravity = (G * M) / (distCenter *distCenter );
Explanation:
Required
Complete the code
The equivalent expression of (G * M) / (d^2) is:
(G * M) / (distCenter *distCenter );
The expression must be stored in accelGravity.
So, we have:
accelGravity = (G * M) / (distCenter *distCenter );

Write a program that uses linear recursion to generate a copy of an original collection in which the copy contains duplicates of every item in the original collection. Using linear recursion, implement a function that takes a list as user-supplied runtime input and returns a copy of it in which every list item has been duplicated. Given an empty list the function returns the base case of an empty list.
Answer: b
Explanation:
Program using linear recursion to duplicate items in a list:
def duplicate_list(lst):
if not lst:
return []
else:
return [lst[0], lst[0]] + duplicate_list(lst[1:])
# Example usage
user_input = input("Enter a list of items: ").split()
original_list = [item for item in user_input]
duplicated_list = duplicate_list(original_list)
print("Duplicated list:", duplicated_list)
How can a program use linear recursion to duplicate items in a list?By implementing a function that utilizes linear recursion, we can create a copy of an original list with duplicated items. The function duplicate_list takes a list lst as input and checks if it is empty. If the list is empty, it returns an empty list as the base case.
Otherwise, it combines the first item of the list with itself and recursively calls the function with the remaining items (lst[1:]). The duplicated items are added to the resulting list. This process continues until all items in the original list have been duplicated and the duplicated list is returned.

cloud offers better protection compare to on premise?
Why is cloud better than on-premise? Dubbed better than on-premise due to its flexibility, reliability and security, cloud removes the hassle of maintaining and updating systems, allowing you to invest your time, money and resources into fulfilling your core business strategies.
The security of the cloud vs. on-premises is a key consideration in this debate. Cloud security controls have historically been considered less robust than onprem ones, but cloud computing is no longer a new technology. . A company running its own on-premises servers retains more complete control over security.

You are consulting with another medium sized business regarding a new database they want to create. They currently have multiple normalized source databases that need consolidation for reporting and analytics. What type of database would you recommend and why
Answer:
The enormous amount of data and information that a company generates and consumes today can become an organizational and logistical nightmare. Storing data, integrating it and protecting it, so that it can be accessed in a fluid, fast and remote way, is one of the fundamental pillars for the successful management of any company, both for productive reasons and for being able to manage and give an effective response to the customers.
Good big data management is key to compete in a globalized market. With employees, suppliers and customers physically spread across different cities and countries, the better the data is handled in an organization, the greater its ability to react to market demand and its competitors.
Databases are nowadays an indispensable pillar to manage all the information handled by an organization that wants to be competitive. However, at a certain point of development in a company, when growth is sustained and the objective is expansion, the doubt faced by many managers and system administrators is whether they should continue to use a database system, or if they should consider the leap to a data warehouse. When is the right time to move from one data storage system to another?
If your organization hires a new employee, what would you do to create a user account in the Linux system and add the account to a group? What commands would you use? What configuration files would you check and modify?
Following are the responses to this question:
The user account is "olivia".In the Linux system to see the account go to the "/home directory".For the configuration file we use ".bash_logout , .bash_profile, and .bashrc" files.Creating users:
We will use the useradd command to achieve this. Using that same command, you can create users who would log in or customers who would log in (in the case of creating a user for a software installation).
In its basic form, the command is as follows:
[Options] useradd usernameTake this user olivia, for instance. Assuming that you had been to issue the command prompt:
olivia has become a user.Users are added to the system without the need for a home directory and are unable to log on. It if we were using this rather than running the command without arguments?
sudo using useradd -m oliviaUsing the command above, a new user would be created, including a home directory that corresponded to the username. That means that you might now see the name "olivia" in the directory "/home".
But what about the lockout concern that was raised earlier? Both these methods are possible. After creating the user, you can enter the following command:
Password for olivia is: sudo passwd oliviaYou'll be requested to enter & verify your new password once you've completed the process. This unlocks the user profile, allowing them to log in.
This command might look like if you wanted to accomplish it in one go:
sudo useradd -m olivia -p PASSWORDYou should be using Passcodes as the login for the user olivia.
As soon as the user logs in, he or she can update their account password by using the password command to input their current password, and afterward entering/verifying their new one.
To create a user that has no personal account and cannot log in, execute the following instructions:
sudo use useradd as the-M USERNAME sudo use usermod as the -L USERNAMEThe user to be added is identified by USERNAME.
It establishes a user with really no root folder and prevents them from signing in with a second operation.
To add an existing user to a group on Linux, follow the instructions:
As root, log in to your accountUse the useradd instruction to add a new user (for example, useradd roman)If you'd like to log on as a new customer, type su plus that user's name.Entering the word "exit" will logout you from your account.Another way to add a user to a group under Linux would be to use the following syntax:
Alternatively, you can use the usermod command.The name of the club should be substituted for example group in this sentence.Example username should be replaced with the name of the user you'd like added.The following operations are performed when a new login is added to the system.
The user's home directory (/home/username by default) is now created.To set configuration files for the user's session, the following secret files are copied into another user's home directory..bash_logout
.bash_profile
.bashrc
/var/spool/mail/username includes the user's mail spool.The new user account is arranged in groups with the same name.Learn more:

Write a program that repeatedly accepts as input a string of ACGT triples and produces a list of the triples and the corresponding amino acids, one set per line. The program will continue to accept input until the user just presses ENTER without entering any DNA codes.
Answer:
Explanation:
The following code is written in Python. I created a dictionary with all the possible gene combinations and their corresponding amino acids. The user then enters a string. The string is split into triples and checked against the dictionary. If a value exists the gene and amino acid is printed, otherwise an "Invalid Sequence" error is printed for that triple.

During the data transmission there are chances that the data bits in the frame might get corrupted. This will require the sender to re-transmit the frame and hence it will increase the re-transmission overhead. By considering the scenarios given below, you have to choose whether the packets should be encapsulated in a single frame or multiple frames in order to minimize the re-transmission overhead.
Justify your answer with one valid reason for both the scenarios given below.
Scenario A: Suppose you are using a network which is very prone to errors.
Scenario B: Suppose you are using a network with high reliability and accuracy.
The packets would be encapsulated in single frame in scenario A. In scenario B, it should be in multi frames.
In scenario A, given that this network has been said to be prone to error, the packets should be encapsulated in single frames.
The reason for this is because, using a single frame helps to decrease error. We have been told already that it is prone to error. If you use the multi frame, there would be very high likelihood of errors occurring.
In scenario B, given that the network is accurate and very reliable, the best packet is the multi frame.
It would give a quicker transmission and the likelihood of errors occurring is also low.

If Scheme were a pure functional language, could it include DISPLAY ? Why or why not?
Answer:
When Scheme is a pure functional language, it cannot include the function DISPLAY. Since the pure functional languages will return the same value whenever the same expression is evaluated, and the DISPLAY would be the output and thus it cannot be part of the purely functional language. Thus in the pure functional language we can evaluate the expressions with the same arguments and it returns the same value since there is no state to change.

Suppose we can buy a chocolate bar from the vending machine for $1 each. Inside every chocolate bar is a coupon. We can redeem six coupons for one chocolate bar from the machine. This means that once you have started buying chocolate bars from the machine, you always have some coupons. We would like to know how many chocolate bars can be eaten if we start with N dollars and always redeem coupons if we have enough for an additional chocolate bar.For example, with 6 dollars we could consume 7 chocolate bars after purchasing 6 bars giving us 6 coupons and then redeeming the 6 coupons for one bar. This would leave us with one extra coupon. For 11 dollars, we could consume 13 chocolate bars and still have one coupon left. For 2 dollars, we could have consumed 14 chocolate bars and have two coupons left.Write a program that inputs a value for N and outputs how many chocolate bars we can eat and how many coupons we would have left over. Use a loop that continues to redeem coupons as long as there are enough to get at least one chocolate bar.
Answer and Explanation:
Using JavaScript:
/* program should take N input which represents the dollar amount and output how many chocolate bars and how many coupons we have*/
function chocolatebar(dollars){
var dollaramt= dollars;

If you were driving the blue Prius in the situation pictured above, explain why the red Mustang should be given right-of-way at this intersection.
Answer:
The red Mustang should be given the right-of-way at this intersection because:
The red Mustang arrived first before the blue Prius and is closer to the stop sign before the arrival of the blue Prius. This implies that the red Mustang must have waited for its turn, unlike the blue Prius that just arrived at the intersection.
Explanation:
Traffic laws, regulations, and IPDE defensive driving strategy require that drivers always give way to the vehicle that arrived before them at an intersection. Assuming that multiple vehicles reach the intersection simultaneously, then the vehicle must be given the right-of-way. Alternatively, the traffic lights at the intersection should be obeyed and be allowed to regulate the movement of vehicles. IPDE defensive driving strategy requires drivers to be watchful of their driving spaces to determine the appropriate time to move.

B. A "while" loop inside of a "for" loop
C. None of the above
D. Either a or b would work
The type of nested loop which I would use to write the program is:
B. A "while" loop inside of a "for" loopWhat is a Loop?This refers to the control flow statement which is used to iterate and lets a particular line(s) of code execute repeatedly
With this in mind, we can see that the type of nested loop which I would use to write the program is a "while" loop inside of a "for" loop because it is a conditional statement that continues to ask for the certain valid grades until it gets the right one.
