I want to succeed in my math class and I came here to get help with problems, especially word problems.
I hope everyone is enjoying their sunday
It's a cold one
I have been trying to work on this problem all day and I cannot get it right and the textbook does not explain how to do it, please help me try to solve it.
If the temperature is constant, then the atmospheric pressure P (in pounds/square inch) varies with the altitude above sea level h (in feet) in accordance with the law given below where p0 is the atmospheric pressure at sea level and k is a constant.
P = p0e^-kh
If the atmospheric pressure is 14.7 lb/in^2 at sea level and 13 lb/in^2 at 4000 ft, find the atmospheric pressure at an altitude of 14,000 ft. (Round your answer to two decimal places.)
?lb/in^2
Have you tried substituting the numbers for known pressures into the equation? What did you get?
Some remarks about typesetting. In plain text, you can indicate subscript with _, e.g., p_0. Next, e^-kh = (e^-k)h because exponentiation has a higher priority than multiplication. In plain text, write e^(-kh). However, it is better to use LaTeX. To get
$\displaystyle P=p_0e^{-kh}$
write [tex]P=p_0e^{-kh}[/tex] (subscripts and superscripts are surrounded by curly braces unless they consist of one symbol).
Wow thank you guys your suggestions really helped me a lot, I tried to ask for help on yahoo answers and no response. Word problems are very hard for me as I said, I hope I don't get any more of them. Thank you again, I greatly appreciate the help
