Answer:

C. 20 to 25 days

Explanation:

The grace period is a period of time you have to pay your credit card balance before interest are charged. The Credit Card Act states that if the financial intitutions decide to grant a grace period, they should be at least of 21 days and usually they are from 21 to 25 days. So, according to this and the options given, the typical grace period for a credit card is 20 to 25 days.

A painting company has determined that for every 115 square feet or wall space, one gallon of paint and eight hours of labor wil

Kay [80]

The program to calculate the total paint cost and other values is given below.

#include <iostream>

using namespace std;

int main() {

int rooms, laborChrg = 18;

float paintChrg;

float feetPerRoom[rooms];

float paintReq, laborHrs, paintCost, laborCost, totalCost, totalsqft=0;

cout<<"Enter the number of rooms to be painted "<<endl;

cin>>rooms;

for(int i=0; i <= rooms; i++)

{

cout<<"Enter the square feet in room "<<endl;

cin>>feetPerRoom[i];

// shortcut operator which is equivalent to totalsqft = totalsqft + feetPerRoom[i];

totalsqft += feetPerRoom[i];

}

cout<<"Enter the cost of the paint per gallon "<<endl;

cin>>paintChrg;

laborHrs = (totalsqft/115)*8;

laborCost = laborHrs * laborChrg;

paintReq = totalsqft/115;

paintCost = paintReq * paintChrg;

totalCost = laborCost + paintCost;

cout<<"The number of gallons of paint required "<<paintReq<<endl;

cout<<"The hours of labor required "<<laborHrs<<endl;

cout<<"The cost of the paint is "<<paintCost<<endl;

cout<<"The labor charges are "<<laborHrs<<endl;

cout<<"The Total cost of the paint job is "<<totalCost<<endl;

return 0;

}

Explanation:

The header files for input and output are imported.

#include <iostream>

using namespace std;

All the variables are taken as float except labour charge per hour and number of rooms.

The user is asked to input the number of rooms to be painted. An array holds the square feet in each room to be painted.

cout<<"Enter the number of rooms to be painted "<<endl;

cin>>rooms;

for(int i=0; i <= rooms; i++)

{

cout<<"Enter the square feet in room "<<endl;

cin>>feetPerRoom[i];

totalsqft += feetPerRoom[i];

}

The above code asks for square feet in each room and calculates the total square feet to be painted simultaneously.

All the data to be displayed is calculated based on the values of labor charge per hour and gallons of paint needed, given in the question.

laborHrs = (totalsqft/115)*8;

laborCost = laborHrs * laborChrg;

paintReq = totalsqft/115;

paintCost = paintReq * paintChrg;

totalCost = laborCost + paintCost;

All the calculated values are displayed in the mentioned order.

To keep a desktop computer or a server powered up when the electricity goes off in addition to protection against power fluctuat

pickupchik [31]

To keep a desktop computer or a server powered up when the electricity goes off in addition to protection against power fluctuations, an <u>uninterruptible power supply (UPS)</u>, which contains a built-in battery, can be used.

<u>Explanation</u>:

An uninterruptible power supply (UPS) is a device that allows a computer or server powered up for a short time, when the electricity goes off. UPS device also provides uninterrupted service during power fluctuation.

A battery is inbuilt in the UPS and provides power for few minutes to the computer to shut down it in a proper manner.

UPS is available at affordable cost and can be maintained at low cost compared to generators.

A video conferencing application isn't working due to a Domain Name System (DNS) port error. Which record requires modification

MrMuchimi

Answer:

Service record (SRV)

Explanation:

Service records (SRV record) are data records stipulating specifications of the DNS such as the port numbers, servers, hostname, priority and weight, and IP addresses of defined or cataloged services servers.

The SRV record is the source of information and the search site about the

location of particular services as such an application i need of such services will look for a related SRV record

A configured SRV is the source of the ports and personal settings for a new email client, without which the parameters set in the email client will be incorrect.

The initial value for a number field on a record is 1. A user updated the value of the number field to 10. This action invokes a

erik [133]

Answer: b. 11

Explanation:

//The initial value is 1

//let call the value as x

x = 1

//then the user updated the value to 10

//so now x is 10

x = 10

// and update the workflow to 11

//so now the value of x is 11

x = 11

even if the programmer print x, so the output will be 11

Generating a signature with RSA alone on a long message would be too slow (presumably using cipher block chaining). Suppose we c

boyakko [2]

Answer:

Following are the algorithm to this question:

Explanation:

In the RSA algorithm can be defined as follows:

In this algorithm, we select two separate prime numbers that are the "P and Q", To protection purposes, both p and q combines are supposed to become dynamically chosen but must be similar in scale but 'unique in length' so render it easier to influence. Its value can be found by the main analysis effectively.

Computing N = PQ.

In this, N can be used for key pair, that is public and private together as the unit and the Length was its key length, normally is spoken bits. Measure,

$\lambda (N) = \ lcm( \lambda (P), \lambda (Q)) = \ lcm(P- 1, Q - 1)$ where $\lambda$ is the total function of Carmichaels. It is a privately held value. Selecting the integer E to be relatively prime from $1$ and $gcd(E, \lambda (N) ) = 1;$ that is $E \ \ and \ \ \lambda (N)$ . D was its complex number equivalent to E (modulo $\lambda (N)$ ); that is d was its design multiplicative equivalent of E-1.

It's more evident as a fix for d provided of DE ≡ 1 (modulo $\lambda (N)$ ).E with an automatic warning latitude or little mass of bigging contribute most frequently to 216 + 1 = 65,537 more qualified encrypted data.

In some situations it's was shown that far lower E values (such as 3) are less stable.

E is eligible as a supporter of the public key.

D is retained as the personal supporter of its key.

Its digital signature was its module N and the assistance for the community (or authentication). Its secret key includes that modulus N and coded (or decoding) sponsor D, that must be kept private. P, Q, and $\lambda (N)$ will also be confined as they can be used in measuring D. The Euler totient operates $\varphi (N) = (P-1)(Q - 1)$ however, could even, as mentioned throughout the initial RSA paper, have been used to compute the private exponent D rather than λ(N).

It applies because $\varphi (N)$ , which can always be split into $\lambda (N)$ , and thus any D satisfying DE ≡ 1, it can also satisfy (mod $\lambda (N)$ ). It works because $\varphi (N)$ , will always be divided by $\varphi (N)$ ,. That d issue, in this case, measurement provides a result which is larger than necessary (i.e. D > $\lambda (N)$ ) for time - to - time). Many RSA frameworks assume notation are generated either by methodology, however, some concepts like fips, 186-4, may demand that D< $\lambda (N)$ . if they use a private follower D, rather than by streamlined decoding method mostly based on a china rest theorem. Every sensitive "over-sized" exponential which does not cooperate may always be reduced to a shorter corresponding exponential by modulo $\lambda (N)$ .

As there are common threads (P− 1) and (Q – 1) which are present throughout the $N-1 = PQ-1 = (P -1)(Q - 1)+ (P-1) + (Q- 1))$ , it's also possible, if there are any, for all the common factors $(P -1) \ \ \ and \ \ (Q - 1)$ to become very small, if necessary.

Indication: Its original writers of RSA articles conduct their main age range by choosing E as a modular D-reverse (module $\varphi (N)$ ) multiplying. Because a low value (e.g. 65,537) is beneficial for E to improve the testing purpose, existing RSA implementation, such as PKCS#1, rather use E and compute D.
