Match the following {:("Column-I","Column-II"),((A)"1 minute",(p)"100 years"),((B)"1 day",(q)"365 days"),((C )"1 year",(r )"24 hours"),((D)"1 century",(s)"60 s"):}
If y=(1)/(x^10)=x^-10 , then find dy//dx .
If x = (1)/( 10) and y = (-3)/( 8) . then evaluate x+y, x-y,x xx y and x div y .
Show that the lines ( x+1)/(-10) = ( y + 3)/(-1) = ( z - 4) / (1) "and" (x + 10)/(-1) = ( y+1)/(-3) = (z -1)/(4) intersect each other and find the coordinates of the points of intersection .
If x+ (1)/(x)= -1 find x^(10) + (1)/(x^(10)) =?
If x+ (1)/(x)=1 , find x^(10) + (1)/(x^(10))=
x is the number of years in a decade. y is the number of decades in a century and z is the number of centuries in a millenium. Find x:y:z
