Question

Water is poured into a container that has a small leak. The mass m of the water is given as a function of time t by m = 4.50t0.8? 2.60t + 21.00, with t ? 0, m in grams, and tin seconds.

Water is poured into a container that has a small leak. The mass m of the water is given as a function of time t by m = 4.50t0.8 ? 2.60t + 21.00, with t ? 0, m in grams, and tin seconds. At what time is the water mass greatest? What is that greatest mass? g In kilograms per minute, what is the rate of mass change at t = 2.00 s? kg/min In kilograms per minute, what is the rate of mass change at t = 5.00 s? kg/min
