1. Let Q1 = x, where (x, y) satisfies that (1)x + (−3)y = −22 (−1)x + (7)y = 54 . Let Q = ln(3+|Q1|). Then T = 5 sin2 (100Q) satisfies:— (A) 0 ≤ T < 1. — (B) 1 ≤ T < 2. — (C) 2 ≤ T < 3. — (D) 3 ≤ T < 4. — (E) 4 ≤ T ≤ 5.

2. Let (Q1, Q2) = (x, y), where (x, y) solves x = (7)x + (−2)y + (−14) y = (−6)y + (−3)x + (26) . Let Q = ln(3 + |Q1| + 2|Q2|). Then T = 5 sin2 (100Q) satisfies:— (A) 0 ≤ T < 1. — (B) 1 ≤ T < 2. — (C) 2 ≤ T < 3. — (D) 3 ≤ T < 4. — (E) 4 ≤ T ≤ 5

3.Let Q1, Q2 be constants so that x = Q1a + Q2 solves the system (−10)x + (9)y = a (−1)x + (−9)y = −8 . Let Q = ln(3 + |Q1| + 2|Q2|). Then T = 5 sin2 (100Q) satisfies:— (A) 0 ≤ T < 1. — (B) 1 ≤ T < 2. — (C) 2 ≤ T < 3. — (D) 3 ≤ T < 4. — (E) 4 ≤ T ≤ 5.

Doubt in this then comment below.. i will explain you.

By rules and regulations we are allow to do only one problem at a time...i solve 2 problems..

.

please thumbs up for this solution..thanks..

.

please check for 2nd problem...i write equations correctly or not... If i write equations correct the answer correct...if i made some mistake then please tell me in comemnt belwo..ok..
