Devise an exponential decay function that fits the given data, then answer the accompanying questions. Be sure to identify the reference point (t = 0) and units of t The pressure of a certain planet's atmosphere at sea level is approximately 1100 millibars and decreases exponentially with elevatiom At an elevation of 35000 ft, the pressure is one-third of the sea-level pressure. At what elevation is the pressure half of the sea-level pressure? At what elevation is it 3% of the sea-level pressure? What is the reference point (t = 0)? 3% of the sea-level pressure the elevation, 35,000 ft the pressure at sea level; 1100 millibars the elevation at sea level, 0 ft What are the units of t? millibars feet pressure levels At what elevation is the pressure half of the sea-level pressure? (Do not round until the final answer. Then round to the nearest whole number as needed.)
