Correct Answer: (D) comedienne

Correct Answer: B. autocracy

Correct Answer: B. \(\frac{a-3b}{a^2-b^2}\)

Explanation

Simplify \(\frac{2}{a+b}-\frac{1}{a-b}; \frac{2(a-b)-1(a+b)}{(a+b)(a-b)}\)

= \(\frac{2a-2b-a-b}{(a+b)(a-b)}\)

= \(\frac{a-3b}{a^2 - ab + ab - b^2}\)

= \(\frac{a-3b}{a^2-b^2}\)

Correct Answer: C. lend

Explanation

The sentence implies that I transferred the book to Olu temporarily, with the expectation of getting it back.

Let's look at the options:

• A. give: To give means to transfer ownership permanently. Since Olu promised to return it, it wasn't a permanent transfer.

• B. borrow: To borrow means to *receive* something from someone else temporarily. If I borrowed Olu my book, it would mean Olu gave me the book. This is the opposite of the meaning implied.

• C. lend: To lend means to *give* something to someone for a period of time, with the expectation that it will be returned. This perfectly fits the context (he promised to return it the following day).

• D. lease: To lease means to grant the use of property for a specific period in exchange for payment. While it involves temporary use, it's typically for more substantial items or property and involves a formal agreement and payment, which isn't suitable for lending a book to a friend.

Therefore, the correct word is lend.

The completed sentence is: I was able to lend Olu my book because he promised to return it the following day.

Correct Answer: B. \(\frac{1}{(x + 1)^{2}}\)

Explanation

\(y = \frac{x}{x + 1}\)

Using quotient rule because the function is of the form \(\frac{u(x)}{v(x)}\)

\(\frac{\mathrm d y}{\mathrm d x} = \frac{v\frac{\mathrm d u}{\mathrm d x} - u\frac{\mathrm d v}{\mathrm d x}}{v^{2}}\)

\(\frac{\mathrm d y}{\mathrm d x} = \frac{(x + 1) . 1 - x . 1}{(x + 1)^{2}}\)

= \(\frac{1}{(x + 1)^{2}}\)
