Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y=3x^{2}-5 -----> quadratic equation of a vertical parabola open upward

Find the inverse function

Exchange variables x for y and y for x

x=3y^{2}-5

Isolate the variable y

3y^{2}=x+5  -----> inverse function (horizontal parabola open to the right)

or

y=(+/-)\sqrt{\frac{x+5}{3}}

using a graphing tool

see the attached figure

Mr. Itol's assistant takes twice as long to complete a computer task as Mr. Itol. If it takes both experts 6 hours to complete t
Lesechka [4]
So, in order to solve this problem, I will set up an equation. First, let's make x= the # of hours it takes Mr. Itol to complete a computer task, and since his assistant takes twice as long, lets make 2x=the # of hours it takes the assistant to complete the task. We also know that it takes the two of them 6 hours to complete the task together. We can now set up the following equation: 

\frac{1}{2x} +  \frac{1}{x} =  \frac{1}{6}

Now, in order to be able to solve this, we have to find the least common denominator, and then we can cancel out the denominators to solve for the top part. The LCD=6x and the new equation becomes: 

\frac{3}{6x} +  \frac{6}{6x} =  \frac{x}{6x}

Now, we can get rid of the denominators, and we get:

3+6=x

So, x= 9

Now we know that Mr. Itol would take 9 hours to complete the task if he were to do it himself. To find how long it would take his assistant to complete the same task by himself, we just need to plug in the x-value into 2x:

2(9)=18

Therefore, your answer is that Mr. Itol would take 9 hours to do the job alone, while his assistant will take 18 hours (double the time) to do the job alone.

Hope this helps :)

-BARSIC- [3]
I think there are missing details in this question. I'll just discuss what an unenrolled tax preparer is.

Unenrolled Tax Preparers are individuals who <span>possess the minimum qualifications required to prepare federal taxes and are granted a Preparer Tax Identification Number (PTIN) but are not Certified Public Accountants (CPA), lawyers, or enrolled agents.

They are only limited to filing only certain types of tax returns and can only represent their client on the basic audit level before the IRS. 

In order for an unenrolled tax preparer to become an enrolled agent, he or she must do the following:
1) Pass a three-part examination before the IRS 
2) Undergo compliance check on their tax history
3) Complete 16 hours of continuing education every year to retain their status. </span>

Travka [436]
Firstly, multiply the principal P, interest in percentage R and tenure T in years.
For yearly interest, divide the result of P*R*T by 100.
To get the monthly interest, divide the Simple Interest by 12 for 1 year, 24 months for 2 years and so on.
