If `(4)/(7)k=36`, then `(3)/(7)k=`

If (a)/(7) = (2b)/(5) = (3a-4b)/(k) , the value of k is …….

The product of 2 (3)/(4) and - 5 (6)/(7) is (- 451)/(7k). Find k.

Find k if -(2)/(7) ,k, -(7)/(2) are in G.P.

If the d.c.s of the line joining the oints P(4,3,5) and Q(1,1,k) are (3)/(7),(2)/(7),(6)/(7) then k =

If (3-"tan"^(2)(pi)/(7))/(1-"tan"^(2)(pi)/(7))="k cos" (pi)/(7) then the value of k is

If int (dx)/((2x-7) sqrt((x-3) (x-4))) = 1/k sec^(-1) (2x-7)+ c , then the value of k is -

Slope of line passes from (3,k) and (2,7) is 2 then k = 7.

If (3-tan^(2)((pi)/(7)))/(1-tan^(2)((pi)/(7)))=k cos((pi)/(7)) then the value 1-tan^(2)((pi)/(7)) of k is (a) (b)2(c)3(d)4

If ^(k+5)P_(k+1)=(11(k-1))/(2)*k+3P_(k)P_(k) then the values of k are 7 and 11 b.6 and 7c.2 and 11 d.2 and 6

If [(1,2),(3,4)][(3,1),(2,5)]=[(7,11),(k ,23)] , then find the value of k.
