Correct Answer: A) Temporary file

Explanation

A '.TMP' file extension usually refers to a temporary file. This is a type of file that is created by software programs to store data temporarily while a new file is being created or to store data that will be deleted later. These files are usually created automatically by the computer and are not meant to be opened or edited by users. They are used to speed up certain processes in the computer by freeing up space and resources.

It is important to note that temporary files are usually deleted automatically by the computer after they have served their purpose. However, it is always a good practice to manually delete these files periodically to free up space on the computer.

In conclusion, when you see a file with a '.TMP' extension on your computer, it usually means that it is a temporary file. It is created automatically by software programs and is not meant to be opened or edited by users. To learn more about this, please read the relevant sections of the recommended textbooks.

Correct Answer: C) palm oil

Explanation

Hydrogenation is a chemical reaction in which hydrogen molecules are added to a compound in the presence of a catalyst, typically a transition metal such as palladium, platinum or nickel. In the food industry, hydrogenation is used to convert liquid vegetable oils into solid or semi-solid fats, which have a higher melting point and are more stable at room temperature.

In the case of palm oil, hydrogenation results in the formation of a solid compound. The correct answer isOption C: palm oil. However, it is important to clarify that the solid compound formed should be referred to ashydrogenated palm oil orsolid palm oil, which is a more accurate description of the product resulting from the hydrogenation process. This compound is used in various food products and household items due to its stability and solid form at room temperature.

Option A, candle, is incorrect as candles are typically made from paraffin wax or beeswax rather than hydrogenated palm oil. Option D, ester, is also incorrect because esters are a class of organic compounds derived from carboxylic acids and alcohols, and are not directly related to the hydrogenation of palm oil.

Correct Answer: A. Once

Correct Answer: C. -30

Explanation

Let \(p(x) = -2x^3 + 6x^2 + 17x - 21\)

Using the remainder theorem

Let \(x + 1 = 0\)

∴ \(x = -1\)

Since, \((x + 1)\) divides \(p(x)\), then, remainder will be p(-1)

⇒ p(-1) = -2(-1)\(^3 + 6(-1)^2\) + 17(-1) - 21

∴ p(-1) = -30
