(a) Let B = . = 4250(1.045) give the balance of a bank account after t years. If the formula for B is written B = 4250ekt, estimate the value of k correct to four decimal places. k≈ 0.04401 (b) The balance of a bank account after t years is given by the formula B = 8500e0.075t. If the formula for B is written B = 8500bt, find b exactly, and give the value of b correct to four decimal places. b= 0.0750 b≈ 0.0750 (to 4 decimal places)
