Let t be time in seconds and let r(t) be the rate, in gallons per second, that water enters a reservoir:
r(t) 500 - 35t.
evaluate the expression r(5) =
which one of the statements below best describes the physical meaning of the value of r(5)?
(a) after how many seconds the water stops flowing into the reservoir and starts to drain out.
(b) the rate at which the rate of water entering the reservoir is decreasing in gallons per second squared.
(c) the rate, in gallons per second, at which the water is initially entering the reservoir.
(d) the average rate, in gallons per second, at which water is flowing out of the reservoir.
(e) how many seconds it takes until there is no longer any water in the reservoir.
