5 (correct), B) 0.866, C) 1, D) 0.707 Explanation: The sine of 30 degrees is equal to 0.5. 2. Which of the following is a quadratic equation?

Options A and D are quadratic equations. 3. Solve the equation: 2x + 5 = 15 (Text: Score 2) Answer: x = 5 Variations: 5, x = 5, x=5, X=5, 5 is the solution, x equals 5, x = 5 is the answer, x=5 is the correct answer, x=5 is the solution Explanation: By subtracting 5 from both sides of the equation, we get 2x = 10. Dividing both sides by 2 gives us x = 5. 4: What is the derivative of f(x) = 3x^2 + 2x - 1?

Therefore, the derivative of f(x) = 3x^2 + 2x - 1 is 6x + 2. 5. Which of the following is a rational number?

Evaluate the expression: 4! (Text: Score 1) Answer: 24 Variations: 24, 4 factorial, 4!, 4 x 3 x 2 x 1, 4*3*2*1, 4 multiplied by 3 multiplied by 2 multiplied by 1, 4 times 3 times 2 times 1, 4 times 3 times 2 times 1 equals 24, 4! equals 24 Explanation: The factorial of a number is the product of all positive integers less than or equal to that number. In this case, 4! Is equal to 4 x 3 x 2 x 1, which equals 24. 7: What is the value of log10(100)?

Solve the equation: 2x - 3 = 7 (Text: Score 2) Answer: x = 5 Variations: 5, x = 5, x=5, X=5, 5 is the solution, x equals 5, x = 5 is the answer, x=5 is the correct answer, x=5 is the solution Explanation: By adding 3 to both sides of the equation, we get 2x = 10. Dividing both sides by 2 gives us x = 5. 9. What is the area of a circle with a radius of 5 units?

Substituting the given radius of 5 units, we get A = p(5^2) = 25p. 10. Which of the following is an irrational number?

Combining like terms, we obtain 2x^2 - 5x - 12. 12: What is the value of tan(45°)?

13. Which of the following is a prime number?

Subtracting 2 from both sides gives us x = 3. 15: What is the value of cos(60°)?

16. Which of the following is a composite number?

18. Solve the equation: 5x - 2 = 3x + 10 (Text: Score 4) Answer: x = 6 Variations: 6, x = 6, x=6, X=6, 6 is the solution, x equals 6, x = 6 is the answer, x=6 is the correct answer, x=6 is the solution Explanation: By subtracting 3x from both sides of the equation and simplifying, we get 2x - 2 = 10. Adding 2 to both sides gives us 2x = 12. Dividing both sides by 2 yields x = 6. 19: What is the value of sin(60°)?

20. Which of the following is a perfect square?

Combining like terms, we obtain -2x + 10. Further simplification gives us 6. 22: What is the value of tan(30°)?

23. Which of the following is a rational number?
