OC. DHTML
OD. XML

Answer:

Following are the solution to this question:

Explanation:

[tex]x^n[/tex] could be approximated by getting a small n loop as well as multiplying x for each incarnation in a linear time. It's very simple. Its key concept is to do it in log2n time.  

[tex]x^n = x^{\frac{n}{2}}\ is \ obvious \ \ x^{\frac{n}{2}}[/tex]

Therefore,[tex]x^{n}, x^{\frac{n}{2}}[/tex] could be determined and divided by itself instead of [tex]x^n[/tex] calculation. It must be done frequently to ensure which half the research is done out with each stage.

Runtime:

Its repetition relationship of the above function is:

[tex]T(n) = T(\frac{n}{2}) + 1[/tex]

This can be resolved by master theorem, so it's obvious. The running time of this repeating ration, by master theorem, is [tex]O ( \log_2n )[/tex].

Pseudocode:

int exponent( int x_1, int y_1 )//defining a method exponent

{

if(y_1==1) //use if to check n value equal to 1  

  {return x_1;} //return x value

  Int t= exponent(x_1,y_1/2);//call method    

return t*t;//calculate  square

}

Answer:

count = 0

for x in range(len(array)):

if count == Len(array) -1:

break

max = max(array[:-1 - count])

count += 1

if array.index(max) == -1:

break

else:

hold = array[-1]

array[-1] = max

array[array.index(max)] = hold

Explanation:

The python program is an implementation of a maxsort. The for loop iterates over the array, getting the maximum number for each reduced array and swaps it with the corresponding last items.

#SPJ2

Answer:

#include <iostream>

using namespace std;

int arrayMinimum(int myArray[], int myArraySize) {

int small = myArray[0];

for (int i = 0; i < myArraySize; i++) {

   if(myArray[i]<small){

small = myArray[i];

}

 }

 return small;

}

int main(){

   int myArray[20];

   for(int i =0;i<20;i++){

       cin>>myArray[i];          

   }

   cout<<"The smallest is: "<<arrayMinimum (myArray,20);

   return 0;

}

Explanation:

This solution is provided in c++

#include <iostream>

using namespace std;

This line defines the arrayMinimum function

int arrayMinimum(int myArray[], int myArraySize) {

This initializes the smallest of the array element to the first

int small = myArray[0];

This iterates through the array

for (int i = 0; i < myArraySize; i++) {

This if condition checks for the smallest

   if(myArray[i]<small){

The smallest is assigned to the small variable

small = myArray[i];

}

 }

This returns the smallest

 return small;

}

The main method begins here

int main(){

This declares an array of 20 elements

   int myArray[20];

The following iteration allows user input into the array

   for(int i =0;i<20;i++){

       cin>>myArray[i];          

   }

This calls the method and returns the minimum

   cout<<"The smallest is: "<<arrayMinimum (myArray,20);

   return 0;

}

Answer: B. Needs the current Xact to finish before another one starts.

Answer:

The answer is below

Explanation:

Let x represent the reliability of each of the five major components. Since all the components must function before the system operates, hence they are in series with each other.

One component has a backup of the same reliability, the reliability of the back up system = 1 - (1 - x)² = 2x - x²

Therefore the reliability of the system is:

x * x * x * x * (2x - x²) = 0.696

2x⁵ - x⁶ = 0.696

x⁶ - 2x⁵ + 0.696 = 0

Solving the polynomial equation online using byjus.com gives:

x = 0.915038

x = 1.97695

x = -0.632585 - 0.429075 i

x = -0.632585 + 0.429075 i

x = 0.186590 - 0.789741 i

x = 0.186590 + 0.789741 i

Since the reliability is not a complex number and it is less than or equal to 1, hence:

x = 0.915038, x ≅ 0.915

Answer:

class Car:

   def __init__(self):

       self.model_year = 0

       # TODO: Declare purchase_price attribute

       self.purchase_price = 0

       self.current_value = 0

   def calc_current_value(self, current_year):

       depreciation_rate = 0.15

       # Car depreciation formula

       car_age = current_year - self.model_year

       self.current_value = round(self.purchase_price * (1 - depreciation_rate) ** car_age)

# TODO: Define print_info() method to output model_year, purchase_price, and current_value

   def print_info(self):

       print("Model year: ",self.model_year)

       print("Purchase year: ",self.purchase_price)

       print("Current value: ",self.current_value)

def main():

   year = int(input())

   price = int(input())

   current_year = int(input())

   my_car = Car()

   my_car.model_year = year

   my_car.purchase_price = price

   my_car.calc_current_value(current_year)

   my_car.print_info()

if __name__ == "__main__":

   main()

Explanation:

The Car class in the python program is used to create a car object instance with class methods model_year, purchase_price, and calc_current_value, which accepts as arguments, year, price and current_year respectively. The main function runs if only the python module is run and interpreted to print out the year and current price of a car object instance defined.

To link to an external style sheet in CSS, use the following syntax:

<link rel = "stylesheet" type = "text/css" href = "link to css file">

As seen above, the link tag is used to achieve this tax.

The rel attributes shows the relationship between the css file and the html file.

In this case, the css file is a stylesheet; hence, rel = "stylesheet"

Next, is the type attribute which shows the content of the file to be linked. In other words, the file type

Lastly, the link to the css file.

Take for instance, the file name is example.css and it is in the same directory as the current document, the following will be used.

href = "example.css"

However, if example.css is in a different directory, the link to the file directory will be stated.

Conclusively, one syntax to use for a file named example.css is:

<link rel = "stylesheet" type = "text/css" href = "exampl.css">

Following are the program to this question:

#include <iostream>//header file

using namespace std;//namespace

class Val //defining abstract class

{

  public://use access specifier

     virtual int squ()=0;//declaring a method squ  

     void setval(int x) //defining a method setval

     {

        a=x;//holding value in a variable

     }

  protected://use access specifier

     int a;//defining integer variable

};

class square: public Val //defining a class square that inherit abstract class

{

  public://use access specifier

   int squ() //defining squ method

   {  

   return (a*a); //return square value

   }

};

int main() //main method

{

 square s;//creating class object

 s.setval(5);//calling setval method

 cout << "The square value is: " << s.squ() << endl;//print value by calling squ method

}

Output:

The square value is: 25

Explanation:

In the above code a two-class "Val and square" is declared, in which val is abstract class, in a method squ is declared, and setval is used to set the value.

In the next step, the square class inherits Val and defines the squ method, and uses the return keyword to return its calculated value.

In the main method square class object is created and set the setval value and call the squ method and print its value.    

Answer:

b) public static double calcShippingCost(double weight) { double cost; if(weight < 10) { cost = 10.0; }else{ cost = 15.5; } cost = cost + calcTax(cost); return cost; }

The method is called twice with arguments 7.5 and 17.5 respectively.

Explanation:

The Java program defines three user methods including the main. In the main, the calShippingCost method is called twice with 7.5 and 17.5 respectively to return double number values to cost1 and cost2.
