Note that in the math problem given, the the value of 4+2 +6r – tr when t = - 3 and r = 5 is 51.

To evaluate the expression 4+2+6r-tr when t = -3 and r = 5,

we substitute the given values for t and r and simplify as follows

4 + 2 + 6r - tr = 4 + 2 + 6(5) - (-3)(5)

= 4 + 2 + 30 + 15

= 51

When we substitute a factor for an expression, we can only do so when the statement has equated that factor with the expression.

So the value of the expression 4+2+6r-tr when t = -3 and r = 5 is 51.

```python

def mergeBy(compare, list1, list2):

   if not list1:

       return list2

   if not list2:

       return list1

   if compare(list1[0], list2[0]):

       return [list1[0]] + mergeBy(compare, list1[1:], list2)

   else:

       return [list2[0]] + mergeBy(compare, list1, list2[1:])

```

The `mergeBy` function takes three arguments: `compare`, `list1`, and `list2`. The `compare` parameter is a function that defines the criterion for merging, such as whether to merge in ascending or descending order. The `list1` and `list2` parameters are the two sorted lists to be merged.

The function uses recursive logic to compare the first elements of `list1` and `list2`. If the criterion defined by the `compare` function is satisfied, the smaller (or larger, depending on the criterion) element is appended to the merged list, and the function is called recursively with the remaining elements of the corresponding list and the other list unchanged. This process continues until either `list1` or `list2` becomes empty.

The resulting merged list will be sorted based on the given criterion defined by the `compare` function.

Note: In the above implementation, it is assumed that the input lists are already sorted based on the given criterion.

A system administrator can start a remote session with a new workstation by using Remote Desktop Protocol (RDP).

What is Remote Desktop Protocol ?

Remote Desktop Protocol (RDP) is a proprietary protocol developed by Microsoft that provides a user with a graphical interface to connect to another computer over a network connection. The protocol allows a user to remotely access the desktop of another computer, as if they were sitting in front of it, and use the remote computer's resources, such as applications, files, and printers.

A system administrator can start a remote session with a new workstation by using Remote Desktop Protocol (RDP). Here are the steps the administrator could follow to start a remote session with a new workstation:

Ensure that the new workstation has Remote Desktop enabled:

On the new workstation, go to Start > Settings > System > Remote Desktop, and make sure that the "Enable Remote Desktop" option is turned on.

On the new workstation, go to Start > Settings > Network & Internet > Ethernet > Change adapter options, and then right-click on the Ethernet adapter and select "Status".

In the adapter status window, click on "Details", and then look for the "IPv4 Address" or "IPv6 Address" value.

Connect to the new workstation from the administrator's computer:

On the administrator's computer, open Remote Desktop Connection (MSTSC.exe).

In the Remote Desktop Connection window, enter the IP address or hostname of the new workstation, and then click on "Connect".

Enter the credentials of an account with administrative privileges on the new workstation.

Start the remote session:

If the connection is successful, a remote session window will appear, allowing the administrator to interact with the new workstation as if they were physically in front of it.

To implement the frame replacement algorithm for virtual memory, you can create a Java program that allows the user to specify the total number of frames in memory (F), the total number of page requests (N), and the sequence of page requests.

Optionally, you can also ask for the total number of pages (TP) to validate the page numbers in the request list. Using this input data, you can calculate the number of page faults for each of the three page replacement algorithms: First-in-first-out (FIFO), Least-recently-used (LRU), and Optimal.

To implement the frame replacement algorithm, you can start by taking input from the user for the total number of frames (F), the total number of page requests (N), and the sequence of page requests. Optionally, you can also ask for the total number of pages (TP) to validate the page numbers in the request list.

Next, you can implement the FIFO algorithm by maintaining a queue to track the order in which the pages are loaded into the frames. Whenever a page fault occurs, i.e., a requested page is not present in any frame, you can remove the page at the front of the queue and load the new page at the rear.

For the LRU algorithm, you can use a data structure, such as a linked list or a priority queue, to keep track of the most recently used pages. Whenever a page fault occurs, you can remove the least recently used page from the data structure and load the new page.

For the Optimal algorithm, you need to predict the future references of the pages. This can be done by analyzing the remaining page requests in the sequence. Whenever a page fault occurs, you can replace the page that will be referenced farthest in the future.

After processing all the page requests, you can calculate and display the number of page faults for each algorithm. The page fault occurs when a requested page is not present in any of the frames and needs to be loaded from the disk into memory.

By implementing these steps, you can simulate the frame replacement algorithm for virtual memory using the FIFO, LRU, and Optimal page replacement algorithms in your Java program.

From a security perspective, there are both pros and cons to the government using outdated IT systems for handling tax filings.

Pros:
1. Familiarity: Government employees are likely more familiar with these older systems, which could potentially minimize user errors that could lead to security breaches.

Cons:
1. Vulnerabilities: Outdated systems often have known security vulnerabilities that can be exploited by hackers or malicious actors, putting sensitive taxpayer information at risk.
2. Lack of updates: Older systems may no longer receive security patches and updates, which could leave them exposed to emerging threats.

Federal agencies may be reluctant to fully embrace cloud computing due to concerns such as data security, privacy, and compliance with regulatory requirements. Additionally, transitioning to cloud infrastructure may require significant financial investment and extensive training for government employees.
