8. A laptop computer's battery has a voltage drop modelled by the function t VG) = 2065, where V is measured in volts, and t is time in hours. (6 marks) *Round all answers to one decimal place. a) What is the initial voltage of the battery? b) What is the voltage after 2 hours? c) The computer will shut off if the voltage drops below 15 volts. How long will this take? d) Calculate the E at which the voltage is dropping after 1 hour
