Best ResponseYou've already chosen the best response.0The temperature of a chemical reaction ranges between 30°C and 70°C. The temperature is at its lowest point when t = 0 and completes one cycle over a sixhour period. What is a sine function that would model this reaction?

Best ResponseYou've already chosen the best response.0OH and here are the answers: f(t) = 20 sin 10t + 50 f(t) = 50 sin 10t + 20 f(t) = 50 sin π/5 t + 20 f(t) = 20 sin π/5 t + 50

Best ResponseYou've already chosen the best response.1hmm i see the period has to be in radians

Best ResponseYou've already chosen the best response.1i would of think that the lowest degree is 30 but they give you 20 as the lowest somehow!

Best ResponseYou've already chosen the best response.1so A and D are not good options since t=0 give 50 which is not lowest degree as claimed!

Best ResponseYou've already chosen the best response.1you would have to convert 6 hour into radions to see what is could be each hour is 2pi radians hmm but then this does not give us what we wanted 12pi is no good

Best ResponseYou've already chosen the best response.1ok let's see at t=6 we have f(6)=70 50sin(6B)+20=70 sin(6b)=1 6b=pi/2 b=pi/12 didn't get that pi/5 there
