Question

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.

Answer 1

This a math home work

Answer 2

means choose one answer

Answer 3

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

Answer 4

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

Answer 5

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

Answer 6

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