A = p (1 + i)n, a = p ert, f v = p m t (1 + i)n (cid:0) 1 i. Solve for x in the following equations: (a) 3x+4 = 27x2(cid:0)3 (b) log(x (cid:0) 3) + log(2 (cid:0) x) = 2 log 2 (c) e3x2+7x = e3(cid:0)x (d) log2(x2 + 3) = 2. For services rendered, an attorney accepts a 180 day note for , 800 at an annual simple interest rate of 8% from a client (both interest and principal are paid at the end of 180 days).
