8. The differential equation 1. will have a slope field with negative slopes in all quadrants II. will have a slope field with positive slopes in all quadrants III. will produce a slope field with rows of parallel tangents I only II only III only 11 lă None of these

dv A model for the velocity v at timetof a certain object faling under the influence cf gravity in a viscous medium is given by the equation 1-. From the direction field shown in the figure to the right, skotch the dt 12 solutions with the initial conditions v(0) = 10, 12, and 19. Why is the value v= 12 calied the "terminal velocity"? Choose the correct skelch of the solutions with the initial conditions v(0) = 10, 12, and 19. O A. OB. Oc.
