<h3>Writing code in Linux:</h3>

<em>def tail(filename, n=10) :</em>

<em>  with open(filename, "r") as </em>

<em>      lines = f.readlines()</em>

<em>   for line in lines[-n:] : </em>

<em>     print (lines) </em>

Norma-Jean [14]

Answer:

Explanation:

I will consult the following strategies:

Step 1: Being a discerning consultant I should be knowing what exactly has caused the drive to get corrupted.

Step 2: After examining the current state of the hard drive I will explain the actual problem to the client in a very lucid and eloquent manner whether it is feasible to retrieve the lost data or it is beyond repair.

Step 3: Identify a solution to the problem with things at my disposal(finding a right tool).

Step 4: apply the solution found to retrieve the data from the hard drive.

Step 5: submitting the retrieved data from the corrupt drive to the customer and advocating them the preventive measures for future reference.

The above five steps will work perfectly to resolve the issue faced if followed with great care and being heedful of the situation at hand.

Explanation:

The status bar appears at the bottom of the page, and it never displays options the options to style the slides. And the toolbar never displays the thumbnails of the slides, as well as the document area never provides a list of the commands for creating, formatting or editing the presentations. However, the rules do indicates the margins, tabs, and indents in a presentation slide. Hence C. is the right option.

num= int(input("Please enter a positive integer: "))#Read the number by user

print("The factors of ",num,"are:")

for k in range(2,num): #iterating over the loop

   if(num%k==0): #checking the condition

       print(k)#display the factor

Output:

Please enter a positive integer: 12

Integral 3t+ 1 / (t + 1)^2​
Verizon [17]

Answer:

3ln|t+1|+\frac{2}{t+1} +C

Explanation:

We'll be using u-substitution for this problem.

Let

u=t+1\\du=dt

Substitute

\int\limits {\frac{3u-2}{u^2}} \, du

Split the fraction

\int\limits {\frac{3u}{u^2} } \, du -\int\limits {\frac{2}{u^2} } \, du

Move the constants out

3\int\limits {\frac{u}{u^2}du -2\int\limits {u^{-2}} \, du

Simplify

3\int\limits {\frac{1}{u}du -2\int\limits {u^{-2}} \, du

Integrate

3ln|u|+\frac{2}{u} +C

Substitute

3ln|t+1|+\frac{2}{t+1} +C
