Subtract 1 from both sides:
Multiply through by -1:
Can you finish off? (use logs)
Been at this for hours..
the temperature ,P, of a conductor at time, t, is given by
Where P^0 is the initial temperature and T is a constant.
Express T in terms of P,P^0 and t and determine its value when p^0 = 190, P= 20 and t = 40
Any help would be much appreciated...Thanks
Thanks for the spoiler, Matches what I had thankfully!
I am stuck with final question - After this hopefully thats me done with algebra!!
Show using factor theorem,that 2x-1 is a factor of...
and hence express 2x^4-x^3-6x^2+5x-1 as a product of a linear & cubic factor
