Answer:

see explaination

Explanation:

please kindly see attachment for the step by step solution of the given problem.

Answer:

Following are the program in the Python Programming Language.

#define function

def isPalindrome(test):

#set the if condition to check tuple is empty

 if(len(test)==0):

   return True

#Check the tuple contain 1 element

 elif(len(test)==1):

   return True

#check the element of tuple is palindrome or not

 else:        

   lenth=len(test)

   #check first last element is equal or not

   if(test[0]==test[lenth-1] and isPalindrome(test[1:lenth-1] ) ):

   #then, return true

     return True

   #otherwise

   else:

   #Return False,

     return False

#define tuple type variable and initialize

test=(1,2,3,4,3,2,1)

#print and call the function

print(isPalindrome(test))

Output:

True

Explanation:

Here, we define a function "palindrome()" and pass an argument in its parameter, inside the function.

• Set the if conditional statement to check the following tuple is empty or not if the tuple is empty then, it returns true.
• Set the elif conditional statement to check the following tuple containing one element, then it returns True.
• Otherwise, we set the length of the tuple in the variable "lenth".
• Then, set if conditional statement to check the first and the last element of the tuple is the same then, returns true.
• Otherwise, it return false.

Answer:

Following are the program in the C++ Programming Language.

//header file

#include<iostream>

//header file

#include <bits/stdc++.h>

//namespace

using namespace std;

//set main function

int main()

{

//set float type variables

float a,s,m,d,c,b,g;

//print message and get variable from the user

cout<<" Enter The First Number : ";

cin>>c;

//print message and get variable from the user

cout<<" Enter The Second Number: ";

cin>>b;

again:

//get variable from the user for Operation

cout<<" Enter the Operation which you want : ";

char choice;

cin>>choice;

//Addition

a=c+b;

//Subtraction

s=c-b;

//Multiplication

m=c*b;

//Division

d=c/b;

//Modulus

g=fmod(c, b);

//set switch statement

//here is the solution

 switch(choice)

 {

   case '+':  

     cout<<"Addition: "<<a<<endl;

     goto again;

     break;

   case '-':

     cout<<"Subtraction: "<<s<<endl;

     goto again;

     break;

   case '*':

     cout<<"Multiplication: "<<m<<endl;

     goto again;

     break;

   case '/':

     cout<<"Division: "<<d<<endl;

     goto again;

     break;

   case '%':

     cout<<"Modulus: "<<g<<endl;

     goto again;

     break;

   default:

     cout<<"Exit";

     break;

 }

return 0;

}Explanation:

Here, we define the required header files then, we set main function.

• set float type variables a,s,m,d,c,b,g.
• Get input from the user for operation in the variable c,d.
• Set character type variables in which we get input from the user for operations.
• Then, we perform some operations.
• Set switch statement which display the output according to the user an if user input wrong then statement breaks.

Answer:

1.  

if(y==0.3){ x = 100;}

2.

if(y == 10){

x = 0; }

else {

x = 1; }

3.

if(sales< 10000){

commission = 0.10;

}

else if(sales>= 10000 && sales <= 15000 ){

commission = 0.15;

}

else{

commission = 0.20;

}

Explanation:

The statements written in brackets represent the conditions while the statements in {...} represent the operation that would be executed depending on the outcome of the if statement.

For 1: if(y==0.3){ x = 100;}

If y is 0.3, 100 would be assigned to x

For 2:

if(y == 10){ x = 0; }

If y is 10, 0 would be assigned to x

else { x = 1; }

If otherwise, 1 would be assigned to x

For 3:

if(sales< 10000){commission = 0.10;}

Is sales is less than 10000, commission would be 0.10

else if(sales>= 10000 && sales <= 15000 ){commission = 0.15;}

If sales is within range of 10000-15000, commission would be 0.15

else{commission = 0.20;}

If otherwise, commission would be 0.20

Answer:

T3.

Explanation:

A T3 is an acronym for Transmission system 3 and it is also known as Digital Signal Level 3 (DS3). T3 is a point-to-point physical circuit connection which is capable of transmitting up to 44.736Mbps.

This simply means that, when using a Transmission system 3 (T3), it is very much possible or easier to transmit data such as video and audio at the rate of 44.736Mbps.

Please note, Mbps represents megabit per seconds and it is a unit for the measurement of data transmission rate. The Transmission system 3 is an internet connection that has up to 672 circuit channels having 64Kbs.

Also, worthy of note is the fact that a T3 line is made up of twenty-eight (28) Transmission system 1 lines (T1) each having a data transfer rate of 1.544Mbps.

Additionally, Transmission 3 lines are symmetrical and duplex and thus, has equal upload and download speeds. Therefore, transmissions can be done on T3 lines simultaneously without the data lines being clogged or jammed.

If you need speeds of 16 Mbps between two corporate sites in the United States, you would need a T3 leased line.

Generally, the T3 lines are mostly used for multichannel applications and uninterrupted high bandwidth consumptions such as Telemedicine, internet telephony, video conferencing, e-commerce etc.

Answer: I would suggest you consider your audience and how you can connect to them. Is your presentation, well, presentable? Is whatever you're presenting reliable and true? Also, no more than 6 lines on each slide. Use colors that contrast and compliment. Images, use images. That pulls whoever you are presenting to more into your presentation.
