A file named loan.html, write an HTML document that looks similar to figure 9-7 in the textbook. Write four functions with these
jok3333 [9.3K]

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.

7. Which cipher is based on the clues of the physical factors, rather than the hardware or a software cryptosystem
Stells [14]

Answer:

The concealment cipher.

Explanation:

A concealment cipher also known as null cipher can be defined as an obsolete encryption format that typically involves the mixture of plaintext with non-cipher elements. This ultimately implies that, the plaintext is hidden in another message through encryption.

The concealment cipher is based on the clues of the physical factors, rather than the hardware or a software cryptosystem.

Basically, the concealment cipher is solely dependent on the clues of the physical factors that mainly affects the sender and receiver in a communication system.
