13) The temperature of a cup of coffee can be approximated by the equation $$T(t) = P(\frac{441}{450})^t$$, where T is the temperature in Celsius, t is time in minutes and P is the initial temperature of the coffee. If the initial temperature of the coffee is 102 degrees celsius, when will the...
Thanks for replying!
We don't go over logarithms for this class (that's next year), so I don't think that my teacher would want us to solve it like that, since this is a question on a test review.
So, is there any other method of solving that, without logarithms? I got the answer $$10$$ kPa...
Atmospheric pressure decreases as altitude increases. The pressure can be approximated by the formula $$P(h) = 101.33(0.9639)^\frac{h}{1000}$$ where $$P$$ is pressure in kilopascals and $$h$$ is height in feet.
a) What is the pressure at sea level (0 feet)?
b) At what altitude will the air...
