MY NOTES
ASK YOUR TEACHER
The temperature T (in °C) at which water boils is related to the elevation h (in meters above sea level) by the formula
h = 1000(100 – T) + 580(100 – T)2
for 95 ST < 100. (a) At what elevation does water boil at a temperature of 97°C? m (b) The elevation of Mt. Everest is approximately 8840 meters. Estimate the temperature at which water boils at the top of this mountain. (Hint: Use the quadratic formula with x = 100 – T. Round your answer to two decimal places.) °C 7:19 PM Thu Feb 4 94% webassign.net - Private 11. [-74.76 Points] DETAILS SWOKPRECALC13 1.4.019.
