Question

15. The air pressure changes with altitude, diminishing as you go higher. This is why some people, climbing the highest mountains, use supplemental oxygen to help them work hard at extreme elevation. If h is the elevation above sea level measured in thousands of feet, the approximate air pressure is given by the formula P(h) = 14.7 (0.97 h) pounds per square inch. Rounded to the nearest hundred feet, at what elevation will the air presure be 7 pounds per square ineh7 (Include units!) Rounded to the nearest tenth pound per square inch, what is the pressure outside the window of an airplane flying 42,500 feet? (Include units!)
