Q. What is the solution to the inequality: x^2 + 3x - 4 ≤ 0?
A.
(-4, 1)
B.
(1, 4)
C.
(-1, 4)
D.
(-4, -1)
Solution
Step 1: Factor the quadratic: (x + 4)(x - 1) ≤ 0. Step 2: Critical points are x = -4 and x = 1. Step 3: Test intervals: (-∞, -4), (-4, 1), (1, ∞). The solution set is [-4, 1].
Q. What is the sum of the first 5 terms of the arithmetic progression 2, 5, 8, ...?
A.
15
B.
30
C.
20
D.
25
Solution
The first term a = 2, common difference d = 3. The sum of the first n terms S_n = n/2 * (2a + (n-1)d). For n = 5, S_5 = 5/2 * (2*2 + 4*3) = 5/2 * (4 + 12) = 5/2 * 16 = 40/2 = 20.
Q. What is the sum of the first 6 terms of the arithmetic progression 1, 4, 7, ...?
A.
60
B.
45
C.
30
D.
36
Solution
The first term a = 1, common difference d = 3. The sum of the first n terms S_n = n/2 * (2a + (n-1)d). For n = 6, S_6 = 6/2 * (2*1 + 5*3) = 3 * (2 + 15) = 3 * 17 = 51.
Q. What is the sum of the first 6 terms of the geometric progression 1, 3, 9, ...?
A.
364
B.
364/2
C.
364/3
D.
182
Solution
The first term a = 1, and the common ratio r = 3. The sum of the first n terms of a GP is S_n = a(1 - r^n) / (1 - r). For n = 6, S_6 = 1(1 - 3^6) / (1 - 3) = (1 - 729) / -2 = -728 / -2 = 364.
