The air in a room 16 ft by 10 ft by 10 ft is 4% carbon monoxide. Starting at tequals0, fresh air containing no carbon monoxide is blown into the room at a rate of 200 ft cubed/min. If air in the room flows out through a vent at the same rate, when will the air in the room be 0.01% carbon monoxide?

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
