| 9 | A | ∫x² dx = x³/3 + C |
| 10 | A | d(e^x)/dx = e^x |
| 11 | B | AM = (2+3)/2 = 2.5 |
| 12 | C | Sum of squares = n(n+1)(2n+1)/6 = 5611/6 = 55 |
| 13 | B | Distance = √((4–1)² + (6–2)²) = √(9+16)=√25=5 |
| 14 | B | y = mx + c → slope = 3/4 → Actually 3x–4y+7=0 → slope = 3/4? Slope m = –A/B = –3/–4 = 3/4 → A |
| 15 | A | x²–4x+4=(x–2)² → roots 2,2 |
| 16 | A | 2x +3 =7 → x=2 |
| 17 | A | Sum of first n odd numbers = n² |
| 18 | B | Identity sin²θ + cos²θ = 1 → valid ∀θ |
| 19 | B | Equal roots → Δ = 0 |
| 20 | A | tan 60° = √3 |
| 21 | A | Sum first 10 even = n(n+1) = 10*11=110 → Correct: B |
| 22 | D | 23² – k3 +4=0 → 18–3k+4=0 → 3k=22 → k=22/3 → Wait options? → Possibly 6 closest → D |
