For this question, enter answers as numerical values. Note the required order for the x-intercepts. Given the function $P(x) = (x - 8)(x + 7)(7x - 2)$, find its y-intercept is y= its x-intercepts are $x_1 =$ , $x_2 =$ and $x_3 =$ with $x_1 \le x_2 \le x_3$ When $x \to \infty$, $y \to$ + ? (Input + or - for the answer) When $x \to -\infty$, $y \to$ - ? (Input + or - for the answer)

D) We decide to enclose the sphere inside of a very long cylindrical shell with constant surface charge density $+\sigma$ and radius 2R such that the center of the sphere is on the axis of the long cylinder as shown in figure. Find electric field at point P (between the sphere and cylinder) (10 pts) - the sphere from R to P is $(R+)\\ (R+S)^2 = \int_0^R \frac{\rho R}{\epsilon_0} = C2\pi R^2\\\frac{2\pi R^2}{\pi R^2+S^2} = \frac{CR^2}{2(R+S)^2} X $\sigma$ 2R $\vec{z}$ P

Q2: Consider continuous model of a system, $G(s) = \frac{-5s + 5}{(s + 2)(s + 4)}$ and its discrete-time transfer function obtained with sampling period T=0.2 as $G(z) = \frac{-0.4845z + 0.598}{z^2 - 1.12z + 0.3012}$ A discrete-time model matching controller is to be designed. The sampling period is given as T=0.2. Specifications for desired closed loop system are as follows. \begin{itemize} \item Damping ratio is $\zeta$=0.7 and settling time to be 3s. \item There shouldn't be steady state error for step input. \end{itemize} Construct the causal and internally stable discrete-time model matching controller that makes the closed-loop system satisfies the mentioned specifications.
