estion Three 1-Draw accurate rate and stock (level) graphs that represent the following equations R stands for Rate Equation and Initial Stock in both cases is R 5 + Step (-7,5) + Ramp (-1,10) = This equation can be explained as follows The initial value of the rate from time-0 is 5, at time =5, the rate steps down to 7 and then ramps to-1 at time 10. R Step (20,5)+ Step (40,10)+ Step (20,15) = 2- Explain the six discipline of peter Senge 3- Explain five system dynamics law
