Calculate the force F needed to punch at 1.46cm diametre hole in a steel plate 1.27cm tjick. tbe ultimate shear stress of the steel is 3.45×10^(8N/m^2 )
Given the function
f(x) = ((ln x)/(x−1))
(a) State the domain D_f of f.
(b) Find lim_(x→∞) ((ln x)/(x−1)). State its asymptotes.
(c) Draw up a variation table for the curve y = f(x).

finish a piece of work in 16 days, 20 days
and 30 days respectively. In how many
days can A, B and C together complete
a work which is 3(1/2) times the previous
work?
