CP11.10 Consider the system represented in state variable form

x(t)=Ax(t)+ Bu(t) y(t)=Cx(t) + Du(t), where A = A=| 0 8.8 B= -25.5 -17.5 19.1 C=[10] and D= [0]. Using the acker function, determine a full-state feedback gain matrix and an observer gain matrix to place the closed-loop system poles at $1,2 = -3 and the observer poles at $1,2 = -18j5.
