please help me to solve this Question ​

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

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.
