The atmospheric pressure on an object decreases as altitude increases. If a is the height (in km) above sea heel, then the pressure P a (in mmHg) is approximated by P a = 760 e − 0.13 a . a. Find the atmospheric pressure at sea level. b. Determine the atmospheric pressure at 8.848 km (the altitude of Mt. Everest). Round to the nearest whole unit.

A 20 foot ladder rests on level ground; its head (top) is against a vertical wall. The bottom of the ladder begins by being 12 feet from the wall but begins moving away at the rate of 0.1 feet per second. At what rate is the top of the ladder slipping down the wall? You may use a calculator.
