Question 10 Scientists have developed a radioisotope-based power supply whose power output in watts is t given by the following function: P = 75.9? where t is the number of days the power supply is used; The experimental power supply has been installed in an unmanned undersea vehicle on an exploration mission. The vehicle requires Twatts to operate at full capacity. Use the given information to nd the number of days for which the vehicle can operate at full capacity
