Write a class named Taxicab that has three **private** data members: one that holds the current x-coordinate, one that holds the

Answer:

Step 1: Create a table reflecting the three potential scenarios and two possible outcomes. There should be a total of 8 distinct rules for the three varying conditions, structured similarly to the discount table shown here in the example: attached is the discount table

Step 2: The rules can now be made simpler by taking the following aspects into account:

a) When a consumer completes the survey form AND opts into the newsletter, according to Rules 1 and 2, they qualify for a discount if their order exceeds $100. This leads to two distinct rules being formulated while the third condition (order quantity) holds significance.

b) If the buyer fills out the survey form OR subscribes to the newsletter, as indicated by Laws 3, 4, 5, and 6, they will benefit from free shipping, regardless of the order amount. As a result, this situation can be divided into two individual rules, where at least one requirement is satisfied, but not both.

c) When a customer fails to meet any requirements, corresponding to Rules 7 and 8, the order value will not qualify for either free shipping or discount. This can be seen as a single law. The linked simplification table illustrates this.

Answer

Abstraction in GPS technology allows the system to use clearly defined interfaces while enabling the integration of additional, more complex functionalities.

Explanation

The GPS system employs abstraction to organize layers of complexity for user interaction. It connects satellite-based positioning and timing systems to enable a radio receiver to acquire signals across four dimensions—latitude, longitude, altitude, and time—after synchronizing this data.

Response:

a. Current disks do not reveal the actual locations of logical blocks.

Clarification:

Modern disks incorporate scheduling algorithms within the disk drive itself. This presents challenges for operating systems trying to optimize rotational latency. All scheduling methods end up having to perform similarly due to potential constraints faced by the operating system. Disks are typically accessed in physical blocks. Modern technology applies more electronic control to the disk.

Question:

The function is_positive should yield True if the supplied number is positive; otherwise, it gives None. Can you fill in the blanks accordingly?

def is_positive(number):

       if  _____ :

           return _____

Answer:

def is_positive(number):

   if (number > 0):

       return True

  else:

       return "None"

---------------------------------------------------------------------------------

Code Test and Sample Output:

print(is_positive(6))

>> True

print(is_positive(-7))

>> None

----------------------------------------------------------------------------------

Explanation:

This segment of code is composed in Python.

To explain it further, let's break down the content of each line;

Line 1: Creates a function identified as is_positive which takes in a variable number.i.e

def is_positive(number):

Line 2: Evaluates if the given number is positive; a number qualifies as positive if it exceeds zero. i.e

if (number > 0):

Line 3: Produces a boolean result of True when the input number is positive. i.e

return True

Line 4: Initiates the else block to be executed in case the input number isn’t positive. i.e

else:

Line 5: Returns the string "None" when the number is not positive. i.e

return "None"

When combined, this results in;

===============================

def is_positive(number):

   if (number > 0):

       return True

   else:

       return "None"

================================

An instance test for the code provided an argument of 6 and -7, resulting in True and None respectively. i.e

print(is_positive(6))   = True

print(is_positive(-7))  = None
