Answer:

Given that:

A= 40n^2

B = 2n^3

By given scenario:

40n^2=2n^3

dividing both sides by 2

20n^2=n^3

dividing both sides by n^2 we get

20 = n

Now putting n=20 in algorithms A and B:

A=40n^2

= 40 (20)^2

= 40 * (400)

A= 16000

B= 2n^3

= 2 (20)^3

= 2(8000)

B= 16000

Now as A and B got same on n = 20, then as given:

n0 <20 for n =20

Let us take n0 = 19, it will prove A is better than B.

We can also match the respective graphs of algorithms of A and B to see which one leads and which one lags, before they cross at n= 20.

Create the strAnalysis() function that takes 1 string argument and returns a string message. The message will be an analysis of
nydimaria [60]

Answer:

def str_analysis(s):

   if s.isdigit():

       s = int(s)

       if s > 99:

           message = str(s) + " is a pretty big number"

       else:

           message = str(s) + " is a smaller number than expected"

       

   elif s.isalpha():

       message = s + " is all alphabetical characters!"

   else:

           message = "There are multiple character types"

   

   return message;

   

s = input("enter word or integer: ")

while s != "":

   print(str_analysis(s))

   s = input("enter word or integer: ")

Explanation:

- Check if the string is digit, alphabetical, or mixed inside the function

- Ask the user for the input

- Call and print the result of the <em>str_analysis</em> function inside the while loop

- Keep asking for the input until the given string is empty

How many inputs are included in the following requirement? REQUIREMENT: Write a program that asks the employee for their age. Th
wolverine [178]

Answer:

The correct answer for the given question is 1

Explanation:

Following are the program in c language  

#include<stdio.h> // header file

#include<conio.h>  //header file

void main()  // main method

{

int age,retiredAge;  // variable

clrscr();  // clear screen

printf("Enter Age : ");

scanf("%d",&age);  // input age

printf("************************");

retiredAge = (65-age);  // calculating retired age

printf("\nYour Age is %d",age);

if(retiredAge<0)  // checking condition

{

printf("\nYou are already cross the retired age. Or Enter Invalid Age.");

}

else

{

printf("\nNo of Years Left to retired is %d",retiredAge);  // dsiplay age

}

getch();

}

Output:

Enter Age : 50

************************

Your Age is 50

No of Years Left to retired is 15

Here Age is the only required input to calculate the retirement age of employee. if entered age is greater than 65 then a message is printed " You are already cross the retired age. Or Enter Invalid Age. " if entered age is valid then retiredAge is calculated with the formula retiredAge = (65-age). and finally display the age,followed by the number of years left to retirement.

Therefore  1 input are required for the above program.

Write a program that takes in a positive integer as input, and outputs a string of 1's and 0's representing the integer in binar
mylen [45]

Answer:

The program to this question can be described as follows:

Program:

num= int(input('Enter a number: ')) #input value by user

st = '' #defining string variable

while num > 0: #define loop to calculte values binary number

   val= num % 2 # holding remainder (0 or 1) in val variable

   st =st+str(val) # store value in str variable

   num = num//2 #calculte quotient value

print("binary number is: ",st)

Output:

Enter a number: 5

binary number is:  101

Explanation:

Program description as follows:

Firstly the "num" variable is declared, for user input, then an "st" variable is declared, to calculates user input value binary number.

In the next step, a while loop is declared, inside the loop, another variable "Val" is declared, that holds value remainders, which is added on the "st" variable.

Outside the loop, the print method is used, that prints st variable holds value.

For python how do I ask the user how many numbers they want to enter and then at the ending add those numbers up together?
Digiron [165]

I am not too familiar with the Python language, but the algorithm would be something like this:

1. create a variable for the sums of the number

2. read in how many numbers the user wants to enter (let's call it N)

and then create a for loop:

for N times

read in the next number

increase the sum variable by that number

Hopefully this helps!
