Answer:
Reconnaissance
Explanation:
You make a purchase at a local hardware store, but what you've bought is too big to take home in your car. For a small fee, you arrange to have the hardware store deliver your purchase for you. You pay for your purchase, plus the sales taxes, plus the fee. The taxes are 7.5% and the fee is $20. (i) Write a function t(x) for the total, after taxes, on the purchase amount x. Write another function f(x) for the total, including the delivery fee, on the purchase amount x. (ii) Calculate and interpret (f o t)(x) and (t o f )(x). Which results in a lower cost to you
Answer:
[tex]f(x) = 1.075x[/tex]
[tex]t(x) = x + 20[/tex]
[tex](f\ o\ t)(x) = 1.075x + 21.5[/tex]
[tex](t\ o\ f)(x) = 1.075x + 20[/tex]
Explanation:
Given
[tex]Tax = 7.5\%[/tex]
[tex]Fee = \$20[/tex] -- delivery
Solving (a): The function for total cost, after tax.
This is calculated as:
[tex]f(x) = Tax *(1 + x)[/tex]
Where:
[tex]x \to[/tex] total purchase
So, we have:
[tex]f(x) = x * (1 + 7.5\%)[/tex]
[tex]f(x) = x * (1 + 0.075)[/tex]
[tex]f(x) = x * 1.075[/tex]
[tex]f(x) = 1.075x[/tex]
Solving (b): Include the delivery fee
[tex]t(x) = x + Fee[/tex]
[tex]t(x) = x + 20[/tex]
Solving (c): (f o t)(x) and (t o f)(x)
[tex](f\ o\ t)(x) = f(t(x))[/tex]
We have:
[tex]f(x) = 1.075x[/tex]
So:
[tex]f(t(x)) = 1.075t(x)[/tex]
This gives:
[tex]f(t(x)) = 1.075*(x + 20)[/tex]
Expand
[tex]f(t(x)) = 1.075x + 21.5[/tex]
So:
[tex](f\ o\ t)(x) = 1.075x + 21.5[/tex]
[tex](t\ o\ f)(x) = t(f(x))[/tex]
We have:
[tex]t(x) = x + 20[/tex]
So:
[tex]t(f(x)) = f(x) + 20[/tex]
This gives:
[tex]t(f(x)) = 1.075x + 20[/tex]
We have:
[tex](f\ o\ t)(x) = 1.075x + 21.5[/tex] ---- This represents the function to pay tax on the item and on the delivery
[tex](t\ o\ f)(x) = 1.075x + 20[/tex] --- This represents the function to pay tax on the item only
The x coefficients in both equations are equal.
So, we compare the constants
[tex]20 < 21.5[/tex] means that (t o f)(x) has a lower cost

Which SCSI standard allows for the technique known as “hot swapping”? Ultra SCSI Original SCSI Serial SCSI Fast-Wide SCSI
Answer:
Serial SCSI
Explanation:
Hot swapping can be defined as a process which typically involves fitting or replacing CD-ROM drive, hard-disk drive, power supply or other peripheral devices while a computer system is powered on. Thus, it allows for the installation or removal of a peripheral device from a computer while power is still being supplied to the computer i.e without having to shutdown the computer.
Serial SCSI is a SCSI standard which allows for the technique known as “hot swapping” because it's a point to point connection that is designed to move data to and from computer storage serially.
When a class implements in interface, it must ________ Group of answer choices overload all of the methods listed in the interface provide all of the nondefault methods that are listed in the interface, with the exact signatures and return types specified not have a constructor be an abstract class
Answer:
provide all of the nondefault methods that are listed in the interface, with the exact signatures and return types specified
Explanation:
I am assuming the programming language is Java. Actually, none of the answers are 100% correct, but this one is the only one that is partially correct. The reason is the class implementing an interface can be abstract, and in this case it may not provide ALL nondefault methods.

When a statement within a try block causes an exception, the remaining statements in the try block Select one: a. are executed after the statements in the catch block b. are executed before the statements in the catch block c. aren't executed
In C++, 'Try block' comprises of a group of statements in which there is a probability of an exception to take place.
C). The statements that would be left in the try block in case a particular statement leads to an exception 'can't be executed.'
In case an exception takes place, the left statements in the try block fail to function. This is the primary reason for which a catch block immediately succeeds a try block in order to deal with the exception and help close that code to allow the statements to work. Thus, option C is the correct answer.Learn more about 'Try block' here:

You are concerned that if a private key is lost, all documents encrypted using your private key will be inaccessible. Which service should you use to solve this problem
Answer:
Key escrow.
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
In Cyber security, encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext.
Typically, an information or data that has been encrypted can only be accessed and deciphered by an authorized user.
Hence, if a private key is lost, all documents encrypted using that private key will be inaccessible to the users. Thus, the service that can be used to solve this problem is a key escrow because the cryptographic (private) keys kept in an escrow system are protected and would not be released to anyone other than the original user (owner).
A key escrow can be defined as a data security method of storing very essential cryptographic keys.
Simply stated, key escrow involves a user entrusting his or her cryptographic key to a third party for storage.
As a standard, each cryptographic key stored or kept in an escrow system are directly linked to the respective users and are encrypted in order to prevent breach, theft or unauthorized access.
