(b) Solve the equation log;(r - 6) =1 - log, (x - 4), reR (c) Find the first derivative of the following functions: (i) y = 273- 1 5r' - 3r (ii) f(x) = 2r - 1 (iii) g(r) = Get cosr (iv) f(t ) = -512 _ 1 vi (d) Show that a-3 is a factor of 223 +52-285-15 and find the other two factors of 23 + 523 -28r - 15. (e) Determine A - 2B where: B- -3 (f) If d = 31 + 27 and 6 =47 -57, find 127 - 61
