Higher altitudes can present challenges to mountain climbers and hikers. One of those challenges is dealing with air pressure changes. A rule of thumb is that air pressure (using inches of mercury) drops about 1 inch for every 1000-foot increase in height above sea level. 1 . Given that the air pressure at sea level is 30 inches of mercury, write a formula for air pressure as a function of height above sea level for this rule of thumb. Call this function the Climber's Estimate and use the function notation C(h). (Ch ) = 30-h 1000 The summit of Babad Do'ag (Mount Lemmon) north of Tucson is roughly 9200 feet above sea level. Use the Climber's Estimate function to estimate the air pressure at the summit of Babad Do'ag. Show your work appropriately. 3. At roughly 14500 feet above sea level, the summit of Tumanguya (Mount Whitney) in California is the highest point in the lower 48 states of the US. Use the Climber's Estimate function to estimate the air pressure at the summit of Tumanguya. Show your work appropriately. 4. At what elevation does the Climber's Estimate predict that the air pressure would be zero? Show your work appropriately. 5. Find the derivative of the Hiker's Estimate function. Explain why the value of the derivative makes sense within the framework of this rule of thumb
