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

Answers

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.

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

Answers

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

16. Which of the following is true about function return statements? A) A function can hold multiple return statements, but only one return statement executes in one function call. B) A function can hold only one return statement. C) A function can hold multiple return statements, and multiple return statements can execute in one function call. D) A function can have maximum of two return statements.

Answers

Answer:

A) A function can hold multiple return statements, but only one return statement executes in one function call

Explanation:

This is because each function can only return one value, whether it be an integer, String, or other object.

However, you can have a series of if-else statements, or case statements, to return a different value depending on information (within parameters, or variables.

Excellent. So, you can have multiple return statements, but the function will only end up executing one of these return statements and return a single value.

Hope this helps!

The statement "When there are multiple return statements but one return statement should execute the 1 function call" is true.

The following information should be considered:

This can be done as every function has only a return i.e. one value. It can be an integer, string, or any other thing. The function can't hold only 1 return statement.The function can't hold many return statements that execute one function call. The function can't have the utmost 2 return statements.

Therefore, we can conclude that option A is correct.

The information included in a résumé should always relate to the job objective; if it isn’t related, it shouldn’t be included.

Answers

Answer:

True.

Explanation:

A resume (curriculum vitae) can be defined as a short text-based document that a job applicant use to briefly outline his or her qualifications, abillities and accomplishments, haven completed and obtained an academic certificate. Thus, it is used to briefly outline a person's qualifications, abillities, skills set, and accomplishments, after completing and obtaining an academic certificate such as a bachelor's degree, master's degree, etc.

Generally, all job applicants are required to have a resume (curriculum vitae). This brief and concise document is always requested by human resource managers during the job application process.

Furthermore, the primary way to make a resume persuasive (to convince or inform an action in the minds of the readers - potential employers) is by customizing it to fit each company and position.

Hence, the information included in a résumé should always relate to the job objective; if it isn’t related, it shouldn’t be included.

This ultimately implies that, job applicants are expected to tailor their resume to fit or match the position that is advertised by a company's human resources department.
