The atmospheric pressure P on a balloon or in aircraft decreases with increasing height . This pressure measured in Millimeters of mercury , is related to the height H (in kilometers) above sea level by the formula p=760e ^ -0.145h. See photo for formula and answer following questions. A.) find the height of an aircraft if the atmospheric pressure is 295 millimeters of Mercury. B.) find the height of a mountain if the atmospheric pressure is 695 millimeters of mercury.
