Correct Answer: D. -\( \frac{7}{36}\)

Explanation

The general form of a quadratic equation is:

\(x^2\) -(sum of roots)\(x\) +(product of roots) = 0

\(7x^2+12x-4=0\)

Divide through by 7

=\(x^2+\frac{12}{7}x-\frac{4}{7}=0\)

=\(x^2-(-\frac{12}{7})x+(-\frac{4}{7})=0\)

\(\therefore\) sum of roots = \(-\frac{12}{7}\), and products of roots =\(-\frac{4}{7}\)

α + β = \(-\frac{12}{7}, αβ = -\frac{4}{7}\)

\(\frac{αβ}{(α + β)^2} = \frac{\frac{-4}{7}}{(\frac{-12}{7})^2}\)

=\(\frac{\frac{-4}{7}}{\frac{144}{49}}=-\frac{4}{7}\times\frac{49}{144}\)

\(\therefore - \frac{7}{36}\)

Dear Tunmise,

It's a pleasure writing to you once again. I hope you are doing great over there in Kaduna? I have missed you and I Know tnat the feeling is mutual. Anyway, as you already know that I hold the position of the Library Prefect in my school, I wish to share my experiences with you.

As you already know that I love reading, I was made the Library Prefect upon reaching SS3 class. As the Library Prefect, It is my duty to assist the Librarian when necessary. My duties include handling the borrowing and returning of books in the school library. I ensure that all the books in the library are accounted for. I make sure that every borrowed book is well documented and the names and classes of the borrowers are taken down. Doing this daily has helped me to be more accountable, I pay attention to details as a result of this role.

One of my duties is to maintain orderliness in the library. Whenever students are in the library seeking for books to read, ensure it is done in an orderly manner. Some students, especially the JSS One students have no idea how the books are arranged on each shelf, despite the indications on them. What I do in such situations is to lead them to the appropriate section, while advising them on the type of books to read.

When students are done reading, I ensure that the shelves are well-arranged and the library tidy always. I do this with the help of the school librarian, she advises from her wealth of experience. Doing this also made me more responsible as I learnt that responsibility comes from being given a role of leadership.

I wish i could keep on writing but I have to stop here. I hope you will share your own experiences with me as the Labour Prefect soon. My regards to your parents and siblings.

Yours sincerely,

Folarin.

Explanation

The Average Cost is the per unit cost of production obtained by dividing the total cost (TC) by the total output (Q). Thus we have; Average cost = Total cost ÷ Total output(quantity) Total cost = fixed cost + variable cost Average cost = 500 + 1500 ÷ 50 2000 ÷ 50 = 40
