for the Q 48 u need 2 find the value of k,
since it is pdf u need to integrate from -nfinity to + infinity to get the value of k.
integrate the given function over the range which is equal to 1 and u will get the value of k.
if u get the value of k the succeeding qn. becomes easy,
integration of kxdx over the range (0,5)+integrate k(10-x)dx over the range(5,10)=1
and u get the value of k
