Correct Answer: A. establishing schools in major cities and teaching the Glorious Quran

Correct Answer: A. 12x² + 11x + 2 = 0

Explanation

x = \(-\frac{2}{3}\) and \(-\frac{1}{4}\)

\(\implies (x + \frac{2}{3}) = 0; (x + \frac{1}{4}) = 0\)

\((x + \frac{2}{3})(x + \frac{1}{4}) = 0\)

\(x^{2} + \frac{1}{4}x + \frac{2}{3}x + \frac{1}{6} = 0\)

\(x^2 + \frac{11}{12}x + \frac{1}{6} = 0\)

\(12x^2 + 11x + 2 = 0\)

Correct Answer: B. 60m

Correct Answer: D. Successive members undergo changes in molecular formula by CH₂

Correct Answer: D) 1024

Explanation

The options provided in the question are: 1000, 1001, 100, 1024 (which is the correct answer), and 10.

To answer the question, we need to know that one kilobyte contains 1024 bytes. This is because computers use a binary system, which means that each unit is a power of 2 (2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, and so on). Therefore, a kilobyte is equal to 2^10 bytes, which is 1024 bytes.

It is worth noting that the other options provided in the question are not correct. Option A (1000) is a common misconception and is often used to represent a kilobyte in decimal systems, but in binary systems, a kilobyte is equal to 1024 bytes. Option B (1001) and Option E (10) are not related to the binary system and are therefore not correct. Option C (100) is also not correct as it is not equal to 1024 bytes.

In conclusion, the correct answer to this question is Option D: 1024

Correct Answer: C. x > 1

Explanation

2x - x\(^2\) > 0

0 > x\(^2\) - 2x

x\(^2\) - 2x < 0

x(x - 2) < 0

x > 1
