a file named loan.html, write an HTML document that looks similar to figure 9-7 in the textbook. Write four functions with these headers:
function doPayment ( )
function doBalance ( )
function computePayment (principal, annualRate, years, periodsPerYear)
function computeBalance (principal, annualRate, years, periodsPerYear, numberOfPaymentPaidToDate)
The first two functions (doPayment and doBalance) do the following:

Take no parameters.
Are called from an onclick attribute.
Get input from the user.
Call the computePayment or the computeBalance function.
Display a result to the user.
The computePayment function computes and returns the monthly payment for a loan with a fixed annual interest rate. The formula for computing a loan payment is

p = ar
1 − (1 + r)−n
Where p is the payment per period, a is the loan amount, r is the interest rate per period, and n is the total number of periods throughout the life of the loan.

The computeBalance function computes and returns the balance for a loan with a fixed annual interest rate. The formula for computing the balance of a loan after d payments have been made is

b = a (1 + r)d − p ( (1 + r)d − 1 )
r
Where b is the balance or payoff amount, a is the loan amount, r is the interest rate per period, p is the payment per period, and d is the number of payments paid to date.

Answer 1

Answer:

function computePayment(principal, annualRate, periodsPerYear){

   var pay;

   pay = (principal * annualRate)/(1-(1+annualRate)-periodsPerYear);

   return pay;

}

function computeBalance(principal, annualRate, periodsPerYear, numberOfPaymentsPaidToDate){

   var balance ;

   let num = (principal*(1+annualRate)*periodsPerYear);

   let denum = numberOfPaymentsPaidToDate *((1+annualRate) * periodsPerYear-1)*annualRate;

   balance = num-denum;

   return balance;

}

function doPayment(){

   let loanAmount = document.getElementById("principal").value;

   let rate = document.getElementById("rate").value;

   let duration = document.getElementsById("time").value;

   let result = computePayment(loanAmount, rate, duration);

   document.getElementsById("periodPay").value = result;

}

function doBalance(){

   let loanAmount = document.getElementById("principal").value;

   let rate = document.getElementById("rate").value;

   let duration = document.getElementById("time").value;

   let currentPaid = document.getElementById("paidMonths").value;

   let result = computeBalance(loanAmount, rate, duration, currentPaid);

   document.getElementById("displayBalance").value = result;

}

Explanation:

The javascript source code defines four functions. The 'doPayment' and 'doBalance' functions are initiated with the onclick properties of the HTML file buttons of the loan calculator. The doPayment function gets the user input from the HTML file and assigns them to variable which are used as the parameters of the computePayment function called.

The doBalance function also retrieve user input from the HTML file and calls the computeBalance function to calculate and return the balance of the loan to be paid.

He is not necessarily interested in going into programming, but he would like to know the basics in terms of how computers work, how programs are written, and how computers communicate with each other. You are talking to him about the basics, but he keeps confusing operating systems, programming language, computer language, and markup language. How would you use very plain language to explain to him the differences between these things and how they interact with each other?

Answers

An operating system is responsible for the overall function of a computer system and it enables us to program a computer through thes use of a computer language.

What is programming?

Programming can be defined as a process through which software developer and computer programmers write a set of instructions (codes) that instructs a software on how to perform a specific task on a computer system.

What is an operating system?

An operating system can be defined as a system software that is pre-installed on a computing device, so as to manage computer hardware, random access memory (RAM), software, and all user processes.

Basically, an operating system is responsible for the overall function of a computer system and as such without it, a computer cannot be used for programming. Also, a computer language is typically used for programming while a markup language is a type of computer language that is mainly used for designing websites through the use of tags.

The function will output positive 1 to the console. This happens because we declare product as 1 inside our function and that value never changes because the while loop only works if the number is greater than 0.

Create a script to input 2 numbers from the user. The script will then ask the user to perform a numerical calculation of addition, subtraction, multiplication, or division. Once the calculation is performed, the script will end.

Answers

Answer:

The code given is written in C++

First we declare the variables to be used during the execution. The names given are self-explanatory.

Then the program outputs a request on the screen and waits for user input, for both numbers and one more time for the math operation wanted, selected with numbers 1 to 4.

Finally, the program executes the operation selected and outputs the result on screen.  

Code:

#include <iostream>

int main()

{

// variable declaration

float numberA;

float numberB;

int operation;

float result=0;

//number request

std::cout<<"Type first number:\n"; std::cin>>numberA;

std::cout<<"Type second number:\n"; std::cin>>numberB;

 

//Operation selection

cout << "Select an operation\n";

cout << "(1) Addition\n";

cout << "(2) Subtraction\n";

cout << "(3) Multiplication\n";

cout << "(4) Division\n";

std::cout<<"Operation:\n"; std::cin>>operation;

switch(operation){

 case 1:

  result = numberA+numberB;

  break;

 case 2:

  result = numberA-numberB;

  break;

 case 3:

  result = numberA*numberB;

  break;

 case 4:

  result = numberA/numberB;

Write a program that prompts the user to enter a Social Security number in the format ddd-dd-dddd, where d is a digit. The program displays Valid SSN for a correct Social Security number or Invalid SSN otherwise.

Answers

ssn = input("Enter a valid Social Security number: ")

dashes = 0

nums = 0

message = "Invalid SSN"

if len(ssn) == 11:

   for x in ssn:

       if x.isdigit():

           nums += 1

       elif x == "-":

           dashes += 1

if nums == 9 and dashes == 2:

   message = "Valid SSN"

print(message)

I wrote my code in python 3.8. I hope this helps!

The program that prompts the user to enter a Social Security number in the format ddd-dd-dddd, where d is a digit can be implemented in Python using regular expressions. The regular expression pattern for the SSN format can be used to validate the input.

Pythons code:

```python

import re

ssn_pattern = re.compile(r'^\d{3}-\d{2}-\d{4}$')

ssn = input("Enter your Social Security Number (format: ddd-dd-dddd): ")

if ssn_pattern.match(ssn):

print("Valid SSN")

else:

print("Invalid SSN")

```

In the above code, we first import the `re` module to work with regular expressions.

We then define the regular expression pattern for the SSN format as `^\d{3}-\d{2}-\d{4}$`. This pattern matches any string that starts with three digits, followed by a hyphen, then two digits, another hyphen, and finally, four digits.

We then prompt the user to enter their SSN using the `input()` function. We then check if the entered SSN matches the pattern using the `match()` function of the regular expression object `ssn_pattern`.

If the SSN matches the pattern, we print "Valid SSN". Otherwise, we print "Invalid SSN".
