## Sariah 4 years ago 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

the answer is50e^(-378/300),use the calculator, you can get

4. physicsfan

shd101wyy is correct - the question is asking you to substitute the value for t given in the problem into the equation for P

but I do not know how to use my calculator LOL, my calculator is not so good

e^(-378/300)*50 = 14.18
