- 5. We learnt the following equation in the class: Ak = sy - (n + 8)k where y = ko. Now, I transform this equation into: Ak/k = sy/k - (n + 8). I want you to use a diagram to show the steady state solution of this equation (In the diagram, there will be two curves - one represents sy/k and one represents (n + 8). In the steady state, of course, Ak/k = 0). In this diagram, the x-axis is k. What will happen to this diagram if the value of n increases?arrow_forwardNot use ai pleasearrow_forward3.
