Question

The 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 10-hour period. What is a sine function that would model this reaction?

Answer 1

I got both... Idk which one is right

f(t) = 50 sin 10t + 20

f(t) = 50 sin pi over 5t + 20

Answer 2

I would say the second
Because the equation to find k goes as follows
\[period= \frac{2 \pi}{10t}= \frac{\pi}{5t}\]

Answer 3

that's what I was thinking actually :)

Answer 4

Wrong the answer is 20sin pi/5t+50

Answer 5

Wrong the answer is 20sin pi/5t+50
