In a small town, the use of coal (w in tons/per
month) isinversely proportional to the averagemonthly
temperature
(t in degrees). the amount of coal used at an average temperature
of 25 degrees is 100tons.
(i) write theequation describing the use of coal
w(t).
(ii)find theamount of coal used during a month
where t = 5 degrees.
(iii)show thatw(t) is decreasing, and find the
gradient of w(t) at t =10.
(iv) what happensto the coal use w, as the average
monthly temperature t gets closerto t = 0. is this formulation is
then practical ?

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
