Transcribed Image Text:The amount of water in a storage tank, in gallons, is modeled by a continuous and differentiable function on the
time interval 0 <t< 10, where t is measured in hours. In this model, the rates are given as follows:
3.
The rate at which water enters the tank is f(t) = 100t? sin(vt) gallons per hour for 0 <t < 10.
The rate at which water leaves the tank is g(t) = 1000x gallons per hour.
а)
Find f (2) and indicate correct units.
Is the amount of water in the tank increasing or decreasing at t =
The rate at which the amount of water in the tank is changing is a(t) = f(t) – g(t). Find a'(5) and
b)
2? Justify your answer.
c)
indicate correct units.
