Write a function called check_third_element that takes in a list of tuples, lst_tups as a parameter. Tuples must have at least 3 items. Return a new list that contains the third element of each tuple. For example, check_third_element([(1,2.2,3.3),(-1,-2,-3),(0,0,0)]) would return [3.3, -3, 0].

Answer:

$2.40

Explanation:

the unit electricity bill is kilo watt hour.

The 60-watt light bulb has a 400 hour life expectency means it will consume

60×400/1000 = 24 KWh units of electricity. Let us suppose each unit of electricity costs is 10 cents.

Then 24×10 = 240 cents  = $2.40

The statement is false. After exporting a PowerPoint presentation to Word, you can still edit it.

When you export a PowerPoint presentation to Word, it converts the content of the presentation into a Word document format, allowing you to view and modify the content within Word. The exported Word document retains the text, images, and formatting from the original presentation, but it is no longer in a slide-based format.

Once the presentation is exported to Word, you can edit the document just like any other Word document. You can modify the text, rearrange content, apply formatting changes, and even insert additional elements. Exporting a PowerPoint presentation to Word is often done to repurpose the content or provide an alternative format for easier editing or collaboration.

The program checks if the entered values are within the range of 2 and 10. If not, an error message is displayed. If the values are valid, the program uses nested loops to generate the grid.

This program allows the user to create grids of various sizes within the specified range (2 to 10) by prompting for input and using nested loops to generate the output. The example provided uses asterisks (*) to represent each cell, but you can modify the program to use any desired output.

A snapshot is a partial copy of a VM that captures the VM's state and any changes made to it since the snapshot was taken. This allows for easy rollback to a previous state if necessary. An incremental backup, on the other hand, captures changes made since the last backup, but may not necessarily be a partial copy of a VM.

To display c Mat(1,1) and c Mat(2,2) as a column using linear indexing, we can create an integer index array by concatenating the linear indices of c Mat(1,1) and c Mat(2,2) in a column-wise fashion.

The linear index of c Mat(1,1) is 1 (since it is the first element in the matrix) and the linear index of c Mat(2,2) is 4 (since it is the fourth element in the matrix). Therefore, the integer index array to display c Mat(1,1) and c Mat(2,2) as a column would be:

[1; 4]

This integer index array can be used to extract the corresponding elements from c Mat and display them in a column using the "display" function.
Using linear indexing to display cMat(1,1) and cMat(2,2) as a column, you will need to convert the 2D indices into 1D indices. For cMat, the conversion is as follows:

Linear index = (row - 1) * number of columns + column

For cMat(1,1):
Linear index = (1 - 1) * 2 + 1 = 1

For cMat(2,2):
Linear index = (2 - 1) * 2 + 2 = 4

So, the integer index array for displaying c Mat(1,1) and c Mat(2,2) as a column is [1, 4].
