The space shuttle environmental control system handles excess (which the astronauts breathe out; it is 4.0% by mass of exhaled air) by reacting it with lithium hydroxide, , pellets to form lithium carbonate, , and water. if there are nine astronauts on board the shuttle, and each exhales 20. l of air per minute, how long could clean air be generated if there were 27,000 g of pellets available for each shuttle mission? assume the density of air is 0.0010 g/ml.

Atank holds 1000 gallons of water, which drains from the bottom of the tank in half an hour. the values in the table show the volume v of water remaining in the tank (in gallons) after t minutes.t(min) 5 10 15 20 25 30v(gal) 694 444 250 111 28 0(a) if p is the point (15, 250) on the graph of v, find the slopes of the secant lines pq when q is the point on the graph with t = 5, 10, 20, 25, and 30.(b) estimate the slope of the tangent line at p by averaging the slopes of two secant lines.(c) use a graph of the function to estimate the slope of the tangent line at p. (this slope represents the rate at which the water is flowing from the tank after 15 minutes.)show all steps.
