 Let, p(x) = x3 + ax2 + bx - 6. Since (x - 2) is a factor of p(x), then, p(2) = 0 or, 23 + a.22 + b.2 - 6 = 0 or, 8 + 4a + 2b - 6 = 0 or, 4a + 2b + 2 = 0    or, 2a + b - 1 = 0 or, 2a + b = 1 ............. .....

Here, Voltage = V = 24V Resistance = R = 60 ohm Current = I =  ? We know,  V = IR or, I =  V / R           = 24 / 60            = 0.4 Amp. Hence, Current in the .....

He introduced a standard system of measurement. He established the fixed rate of courts. He developed trade with neighbouring kingdoms. He made religious reforms and so on. He was a learned king and respected scholars known as a just and fair .....

Here, S.P. = Rs.90. C.P = Rs.75, As SP > CP, there is profit. We know,  Profit  =  SP - CP               = Rs.90 - Rs.75              = Rs. .....

Here, n1 = 3 n2 Out put voltage = V2 = 999V Input voltage = V1 = ? You may know that  Voltage is directly proportional to number of turns. i.e. V1/V2= n1/n2 Here, V1/999 = 3n2 / n2 V1=2997V. Hence input voltage = .....

Lymph nodes filter lymph, a clear, sticky fluid that bathes body cells and collects waste products and debris. You know that white blood cells protects our body against viruses and bacteria. Lymph carries white blood cells and thus lymph .....

When the body breaks down proteins, they are turned into carbon dioxide, water, and ammonia. You may know that ammonia is toxic and would destroy our cells. So, our body must convert it into something less toxic. Our liver turns the ammonia into .....

We know, 25o + 75o + 80o = 180o or, 25o + 75o  = 180o - 80o Opereting both sides by tan,  tan ( 25o + 75o ) = tan ( 180o - 80o ) Using formula of   tan (A + B)  and tan (180 - X)  = - tan X we get, [Tan25o + tan .....

Let ,  CP = y,  From the frist case, SP = CP - 25% of CP       = y - 25/100 X y = 3y / 4. From the second case,  SP = 3y /4 + 2100 Profit = 10% WE know,  SP = CP + 10% of CP or, 3y/ 4 + 2100 = y + .....
