Solve the problem. Instruments on a satellite measure the amount of power generated by the satellite's power supply. The time t and the power P can be modeled by the function P = 50e^{-t/300}, where t is in days and P is in watts. How much power will be available after 378 days? Round to the nearest hundredth. Seleccione una respuesta. a. 1.41 watts b. 141.8 watts c. 14.18 watts d. 0.14 watts
