The atmospheric pressure p on a Hot air balloon or airplane decreases with increasing height. This pressure, measured in millimeters of mercury, is related to the height h (in kilometers) above sea level by the function:
(a) Find the atmospheric pressure at a height of 2 km (over a mile).
(b) What is it at a height of 10 kilometers (over 30,000 feet)?
(C) Use Desmos Graphing calculator to graph the function
(D) Find the x and y intercepts.
(E) Find the height of an aircraft if the atmospheric pressure is 320 millimeters of mercury.
(F) Find the height of a mountain if the atmospheric pressure is 667 millimeters of mercury.
