Answer:

A good identifier for a variable that will be used to hold an employee’s phone number is:

a. EmployeePhoneNumber

Explanation:

An identifier is a string that uniquely identifies or names the entity or an object.  The object or entity may be a constant, variable, structure, function, etc. Identifiers can be formed from uppercase and lowercase letters, digits, and underscores.  Meaningful identifiers mostly favor the use of long descriptive names like EmployeePhoneNumber.  However, the other options can still be used.

The set of three integer values for the lengths of the sides of a right triangle is called a Pythagorean triple. These three sid
Sloan [31]

Answer:

In Python:

def  Pythagorean_triple(hyp,side1,side2):

   if hyp**2 == side1**2 + side2*2:

       return True

   else:

       return False

               

print("Hypotenuse\tSide 1\t Side 2\t Return Value")

for i in range(1,501):

   for j in range(1,501):

       for k in range(1,501):

           print(str(i)+"\t"+str(j)+"\t"+str(k)+"\t"+str(Pythagorean_triple(i,j,k)))

Explanation:

This defines the function

def  Pythagorean_triple(hyp,side1,side2):

This checks for pythagorean triple

   if hyp**2 == side1**2 + side2*2:

Returns True, if true

       return True

   else:

Returns False, if otherwise

       return False

               

The main method begins

This prints the header

print("Hypotenuse\tSide 1\t Side 2\t Return Value")

The following is a triple-nested loop [Each of the loop is from 1 to 500]

for i in range(1,501): -->The hypotenuse

   for j in range(1,501): -->Side 1

       for k in range(1,501):-->Side 2

This calls the function and prints the required output i.e. the sides of the triangle and True or False

           print(str(i)+"\t"+str(j)+"\t"+str(k)+"\t"+str(Pythagorean_triple(i,j,k)))
