.The value of a machine is depreciating using the exponential function = 0
− where k is a
constant, 0
is initial value of the machine and t is time in years. The value of the machine
after 5 years is Sh. 758,590.4078 and its value after 8 years is Sh. 662,792.5098. Calculate the:
a) Value of k (3 Marks)
b) Initial value of the machine.
