Option D is the answer because Digital Certificate is an entity that generates electronic and distributes them upon proving their identity sufficiently. In early days there was issues with people using the certificates that were not even issued by the organizations. Today it's a cryptographic technique which uses digital signatures and gives users a digital certificate that can be authenticated anytime online by any organization and is unique for every user having it.

Option A cannot be the answer because it has nothing to do with the identity of person but rather it is for specific fields.

Option B is not answer because it has no key and score matter to do with it.

Option C Web transactions has nothing to do with the certificates.

What is the inverse function of d(x ) = -2x - 6?
PtichkaEL [24]

Answer:

-\frac{x}{2} - 3

Explanation:

d(x) = -2x - 6

to find the inverse of a function, you need to follow these steps:

1. set d(x) = y

2. interchange the variables, so y becomes x and x becomes y

3. solve the equation for y

<u>step 1:</u> set d(x) = y

y = -2x -6

<u>step 2:</u> interchanging the variables

y = -2x - 6 turns into x = -2y - 6

<u>step 3:</u> solving for y

x = -2y - 6 < add 6 to both sides to get rid of it on the right

x + 6 = -2y < divide both sides by -2 to get y alone

x + 6 / -2 = -\frac{x}{2} - 3

-2y / -2 = y

-\frac{x}{2} - 3 = y

so the inverse of the function is -\frac{x}{2} - 3

Public static void prefixmerge(customer[] list1, customer[] list2, customer[] result {
White raven [17]
I can't get what do you need, but I guess it's a part of java code. I can explain what it means. It's used to unite two rising sorted arrays which are list1 and list2. The result is stored in result array. I suggest you to clearly explain your task as it's difficult to give you correct answer.

zaharov [31]

Answer:

The undo tool.

Explanation:

Microsoft Excel is a spreadsheet application developed by Microsoft, it is used for analysing data. It's worksheets are made up of columns and rows or fields and records.

There are different ways of entering data to a cell. Click on the cell and type the data, copy and paste to the target cell, double-click on the cell to correct data and click on a cell and press the spacebar key to clear the data.

Excel records the action of event, so when a mistake is made like deleting a crucial cell data value, the undo tool is used to recover the data, since it holds records of events. The redo tool is the reverse of the undo tool.
