How to reset a master combination lock without the code.
Dovator [93]

The resetting of a master combination lock without the code can be done by using a database system.

<h3>What is a database system?</h3>

A database-management system is made up of a compilation of interconnected data and a set of tools that allow you to access that data. The information pertains to a particular enterprise.

A database-management system's major purpose is to offer individuals a system that is both efficient and convenient for obtaining and recording information.

In order to do this, there are keys that need to be unlocked to access these data. Hence, the use of a master combination lock is required.

Let's assume we have the image below, the way to unlock the code is as follows:

  • Okay, so we have the numbers {6,8,2,1,4,0,7,3}

Let's take a quick look at the fourth hint, we have the eliminate 8, 7, and 3.

  • The returned values =  {6, 2, 1, 4, 0}

From the first and second hints, we can deduce that 6 is out of it since is in the same position and it cannot be wrongly and correctly placed at the same time.

  • Returned Values = { 2, 1, 4, 0}

The third hint says two numbers are correct but wrongly placed, but the first hint let us know that one number is correct and correctly placed. This confirms that 2 is in the last position of our key.

Now, we have:

  • Returned values ={0,1, 4}
  • Output ={<u>   </u>, <u>   </u> , 2}

We use an analogy here i.e. in database system hierarchy, data types are arranged in hierarchical order(H.O) except when an exception is being made.

Now, hint three told us that two numbers are correct i.e. 0 and 2 since 6 is out. However, hint five helps us to confirm that 0 is part of our output values.

  • Returned values = {1,4}
  • Output = {0, __, 2}......  (H.O) with exception of 2 being the last digit.

From hint two, one number is correct but wrongly placed, we are still looking for the middle number but since it is wrongly placed, it cannot be 1, hence, it is 4.

  • Returned values = {1,4}
  • Output = {0, 4, 2}

Therefore, the master combination lock of our code for the password is {0, 4, 2}

(A) Give ONE advantage and ONE disadvantage that urbanization has when compared to rural areas. (B) Identify TWO factors that ha
zhuklara [117]

Answer:

(A) Urbanization makes it easier to proportion services like medical services and education because people are more concentrated in urban areas. Rural areas are hard to supply with specialized services. A disadvantage is that crime tends to be statistically higher in urban areas.

Explanation:

In addition to the advantages and disadvantages of urbanization (B) Two factors that have led to the urban sprawl is 1) lack of urban planning and 2) rapid population growth that leads to overcrowding and traffic problems that compel people to move elsewhere or to travel long distances and thus adding to the urban sprawl.  (C) An economic disadvantage that cities may face is that services may be overburdened and it can lead to lower quality of life and higher poverty indicators in inner cities, for example.  (D) Urban sprawl has a negative impact on the environment because more people use private transportation because they have to travel long distances, thus increasing pollution. It also increases the need for parking and thus increasing the price of parking and making a sustainable form of life difficult for most wage earners. (E) Two practices that would be emphasized to create sustainable cities would be to encourage the use of public transportation and non-motorized vehicles like bicycles to reduce pollution and the levels of car traffic in the city.
