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.

Describe the output when the following code executes in 64-bit mode: .data dividend_hi QWORD 00000108h dividend_lo QWORD 3330002

iragen [17]

Answer:

RAX = 333000h (16 bits with preceding zeros removed)

RDX = 20h (also 16 bits with preceding zeros removed)

Explanation:

The "div" opcode in the assembly language source code is used to divide operands. It accepts a divisor ( the denominator) and divides the content of the AX register. The result is saved in the AX register while the remainder (if any) is saved in the DX register. If the DX register holds any data, the data is replaced with the divisor remnant.

The code above divides the content of the RAX register with the divisor variable and saves the result and remainder in the RAX and RDX respectively.

Referential integrity constraints are concerned with checking INSERT and UPDATE operations that affect the parent child relation

Jet001 [13]

Answer:

a) true

Explanation:

In Computer programming, integrity constraints can be defined as a set of standard rules that ensures quality information and database are maintained.

Basically, there are four (4) types of integrity constraints and these are;

1. Key constraints.

2. Domain constraints.

3. Entity integrity constraints.

4. Referential integrity constraints.

Referential integrity is a property of data which states that each foreign key value must match a primary key value in another relation or the foreign key value must be null.

For instance, when a foreign key in Table A points to the primary key of Table B, according to the referential integrity constraints, all the value of the foreign key in Table A must be null or match the primary key in Table B.

Hence, the referential Integrity constraints ensures that the relationship between the data in a table is consistent and valid.

Hence, referential integrity constraints are concerned with checking INSERT and UPDATE operations that affect the parent child relationships.

<em>This ultimately implies that, referential Integrity are rules used in database management systems (DBMS) to ensure relationships between tables when records are changed is VALID (INSERT and UPDATE).</em>

<em>In a nutshell, it always ensures a primary key must have a matching foreign key or it becomes null. </em>

Write a method called fact that recursively calculates the factorial value of its single int parameter. The value returned by fa

andrey2020 [161]

Answer:

The program to this question can be given as follows:

Program:

//class

public class factorial //defining class

{

//method fact

public static long fact(int x1) //defining method fact

{

//conditional statement

if (x1 <= 1) //if block checks parameter value less then equal to 1

{

return 1; //return value

}

else //else part

{

return (fact(x1 - 1) * (long) x1); //return factors using recursive function

}

//method main

public static void main(String[] args) //defining main method

{

long data=fact(5);//defining variable that holds function value

System.out.println("Factorial is: "+data); //print value

}

Output:

Factorial is: 120

Explanation:

In the above java program, a class is "factorial" is defined, inside the class, a static method "fact" is declared, that accepts an integer parameter that is "x1" and returns a long value, inside this method a conditional statement is used.

If the block it checks parameter value is less then equal to 1, if this condition is true, it will return 1 when this condition is not true. It will go in else part.

In else part, it uses a recursive function to calculate factorial of a number and return its value.
Then the main method is defined, inside this method a long variable "data" is defined, that call and holds fact function return value, and in the next line, the print function is used to print the data variable value.

Give a proof for each statement.

Marrrta [24]

Answer:

If a group of 9 kids have won a total of 100 trophies, then at least one of the 9 kids has won at least 12 trophies.
If a person buys at least 400 cups of coffee in a year, then there is at least one day in which the person has bought at least two cups of coffee.
The average of three real numbers is greater than or equal to at least one of the numbers.

Explanation:

Suppose that each kid has less than 12 trophies

Total trophies = 100

Maximum trophies won by one kid = 11

total kids = 9

total number of trophies = 9 * 11 = 99 which contradicts the fact the total number of trophies are 100

Suppose that person has less than 2 cups of coffee a day

Total cups of coffee = 400

he has bought at least one cup of coffee each day

which means

total number of cups of coffee = 1* 366 = 366 which contradicts the fact the person buys at least 400 cups of coffee in a year

Average of three number = (a+ b+ c)/3

suppose that there are real numbers a, b, and c such that all three numbers are less than the average of the three numbers.

Let m be the average (a+b+c )/3 = m. Then our assumption states that (a < m) and (b < m) and (c < m). By adding all the inequalities we get a + b + c < 3m. But m is defined to be (a+b+c) /3 , so a + b + c = 3m. But now we have that 3m = a + b + c < 3m. So 3m < 3m which is an obvious contradiction. Thus our claim is true
