Can someone please explain it to me ASAP?!!! This is velocity and net changes. I need help for the second part.

simple model for the flow of air in and out of the lungs of a certain mammal is given by the following equation, where V(t) (measured in liters) is the volume of air in the lungs at time ( 2 0, t is measured in omplete parts a through c below. d t = 0 corresponds to a time at which the lungs are full and exhalation begins. Only a fraction of the air in the lungs is exchanged with each breath. The amount that is exchanged is called the tidal volum V' (t) = 5 sin . . . . . a. Find the volume function V, assuming that V(0) =6 L. Notice that V changes over time at a known rate, V'. Which equation below correctly gives the volume function? O A. V (0) = V(t ) + |V' ( x ) dx . b O B. V(t) = V(0) + ( V' (t ) at . a b O c. V(0) = V(t) + | V'(t)at. D. V (t) = V(0 ) + V ' ( x ) dx . Find the volume function V, assuming that V(0) = 6 L. V(t) = (Type an exact answer.) Clear All Check Answer Help Me Solve This View an Example Get More Help - 5:58 PM 21 . C ENG O W 9/2/2021 Type here to search
