If the mean of the following data is 15, find p . x : 5 10 15 20 25 f : 6 p 6 10 5

Electromagnetic wave in a medium of mu_(r) = 1 is given as E = 20 sin (20 x 10^10 - 20 x 10^2 x) . Dielectric constant of medium is 1/x then find x

Find the value of x in each of the following (i) 2 : 5: : x : 20 (ii) x : 10 : : 15 : 30

Divide 10x^(3) + 41x^(2) - 4x - 15 by 5x + 3 .

lim_ (x rarr oo) ((x + 2) ^ (10) + (x + 4) ^ (10) ++ (x + 20) ^ (10)) / (x ^ (10) +1) =
