Given that f(x) =x^3-kx^2-2x+1 gives a remainder k when divided by x-k,find the value of k

Initially 48g of ice at 0 degrees celsius is in an aluminium calorimeter can of mass 2.0 g also at 0 degrees celsius.Then 75g OF water at 80 degrees celsius is poured into the can.What is the final temperature.

evaluate lim of x as it approaches infinity for sqrt of x^2 -1/2x+1

find intergral (x^2)/sqrt(x^2+25)
