Input 3 positive integers from the terminal, determine if tlrey are valid sides of a triangle. If the sides do form a valid triangle, output the type of triangle - equilateral, isosceles, or scalene - and the area of the triangle. If the three integers are not the valid sides of a triangle, output an appropriats message and the 3 sides. Be sure to comment and error check in your progam.

Answers

Answer:

In Python:

side1 = float(input("Side 1: "))

side2 = float(input("Side 2: "))

side3 = float(input("Side 3: "))

if side1>0 and side2>0 and side3>0:

   if side1+side2>=side3 and side2+side3>=side1 and side3+side1>=side2:

       if side1 == side2 == side3:

           print("Equilateral Triangle")

       elif side1 == side2 or side1 == side3 or side2 == side3:

           print("Isosceles Triangle")

       else:

           print("Scalene Triangle")

   else:

       print("Invalid Triangle")

else:

   print("Invalid Triangle")

Explanation:

The next three lines get the input of the sides of the triangle

side1 = float(input("Side 1: "))

side2 = float(input("Side 2: "))

side3 = float(input("Side 3: "))

If all sides are positive

if side1>0 and side2>0 and side3>0:

Check if the sides are valid using the following condition

   if side1+side2>=side3 and side2+side3>=side1 and side3+side1>=side2:

Check if the triangle is equilateral

       if side1 == side2 == side3:

           print("Equilateral Triangle")

Check if the triangle is isosceles

       elif side1 == side2 or side1 == side3 or side2 == side3:

           print("Isosceles Triangle")

Otherwise, it is scalene

       else:

           print("Scalene Triangle")

Print invalid, if the sides do not make a valid triangle

   else:

       print("Invalid Triangle")

Print invalid, if the any of the sides are negative

else:

   print("Invalid Triangle")

Write out code for a nested if statement that allows a user to enter in a product name, store the product into a variable called product_name and checks to see if that product exists in your nested if statement. You must include 5 product names to search for. If it is then assign the price of the item to a variable called amount and then print the product name and the cost of the product to the console. If it does not find any of the items in the nested if statement, then print that item cannot be found.

Part 1 of 4 parts for this set of problems: Given an 4777 byte IP datagram (including IP header and IP data, no options) which is carrying a single TCP segment (which contains no options) and network with a Maximum Transfer Unit of 1333 bytes. How many IP datagrams result, how big are each of them, how much application data is in each one of them, what is the offset value in each. For the first of four datagrams: Segment

Answers

Answer:

Fragment 1: size (1332), offset value (0), flag (1)

Fragment 2: size (1332), offset value (164), flag (1)

Fragment 3: size (1332), offset value (328), flag (1)

Fragment 4: size (781), offset value (492), flag (1)

Explanation:

The maximum = 1333 B

the datagram contains a header of 20 bytes and a payload of 8 bits( that is 1 byte)

The data allowed = 1333 - 20 - 1 = 1312 B

The segment also has a header of 20 bytes

the data size = 4777 -20 = 4757 B

Therefore, the total datagram = 4757 / 1312 = 4

Here is the answer for the question

________ can be written only once. The data cannot be erased or written over once it is saved.​

Answers

Answer:

WORM (Write Once, Read Many)

Explanation:

The full meaning which means Write Once, Read Many implies that data can only be entered (or better put, written) once. Once the data has been written, the data can not be updated or deleted. However, the data being stored on WORM can be read as many times, as possible.

Hence, WORM answers the question.

Scenario
Your task is to prepare a simple code able to evaluate the end time of a period of time, given as a number of minutes (it could be arbitrarily large). The start time is given as a pair of hours (0..23) and minutes (0..59). The result has to be printed to the console.
For example, if an event starts at 12:17 and lasts 59 minutes, it will end at 13:16.
Don't worry about any imperfections in your code - it's okay if it accepts an invalid time - the most important thing is that the code produce valid results for valid input data.
Test your code carefully. Hint: using the % operator may be the key to success.

Answers

Answer:

In Python:

hh = int(input("Start Hour: "))

mm = int(input("Start Minute: "))

add_min = int(input("Additional Minute: "))

endhh = hh + (add_min // 60)  

endmm = mm + (add_min % 60)

endhh += endmm // 60

endmm = endmm % 60

endhh = endhh % 24  

print('{}:{}'.format(endhh, endmm))

Explanation:

This prompts the user for start hour

hh = int(input("Start Hour: "))

This prompts the user for start minute

mm = int(input("Start Minute: "))

This prompts the user for additional minute

add_min = int(input("Additional Minute: "))

The following sequence of instruction calculates the end time and end minute

endhh = hh + (add_min // 60)  

endmm = mm + (add_min % 60)

endhh += endmm // 60

endmm = endmm % 60

endhh = endhh % 24  

This prints the expected output

print('{}:{}'.format(endhh, endmm))

Suppose that a computer has three types of floating point operations: add, multiply, and divide. By performing optimizations to the design, we can improve the floating point multiply performance by a factor of 10 (i.e., floating point multiply runs 10 times faster on this new machine). Similarly, we can improve the performance of floating point divide by a factor of 15 (i.e., floating point divide runs 15 times faster on this new machine). If an application consists of 50% floating point add instructions, 30% floating point multiply instructions, and 20% floating point divide instructions, what is the speedup achieved by the new machine for this application compared to the old machine

Answers

Answer:

1.84

Explanation:

Operation on old system

Add operation = 50% = 0.5

Multiply = 30% = 0.3

Divide = 20% = 0.2

T = total execution time

For add = 0.5T

For multiplication = 0.3T

For division = 0.2T

0.5T + 0.3T + 0.2T = T

For new computer

Add operation is unchanged = 0.5T

Multiply is 10 times faster = 0.3T/10 = 0.03T

Divide is 15 times faster = 0.2T/15= 0.0133T

Total time = 0.5T + 0.03T + 0.0133T

= 0.54333T

Speed up = Old time/ new time

= T/0.54333T

= 1/0.54333

= 1.84

Write a function named printPattern that takes three arguments: a character and two integers. The character is to be printed. The first integer specifies the number of times that the character is to be printed on a line (repetitions), and the second integer specifies the number of lines that are to be printed. Also, your function must return an integer indicating the number of lines multiplied by the number of repetitions. Write a program that makes use of this function. That is in the main function you must read the inputs from the user (the character, and the two integers) and then call your function to do the printing.

Answers

Answer:

import java.util.Scanner;

public class Main

{

public static void main(String[] args) {

    Scanner input = new Scanner(System.in);

    char c;

 c = input.next().charAt(0);

 System.out.print("Enter the number of times that the character is to be printed on a line: ");

        }

        System.out.println();

    }

    return n1 * n2;

}

}

Explanation:

*The code is in Java.

Create a function named printPattern that takes one character c, and two integers n1, n2 as parameters

Inside the function:

Create a nested for loop. Since n2 represents the number of lines, the outer loop needs to iterate n2 times. Since n1 represents the number of times that the character is to be printed, the inner loop iterates n1 times. Inside the inner loop, print the c. Also, to have a new line after the character is printed n1 times on a line, we need to write a print statement after the inner loop.

Return the n1 * n2

Inside the main:

Declare the variables

Ask the user to enter the values for c, n1 and n2

Call the function with these values
