(a) Use synthetic division to show that 2 is a solution of the polynomial equation 5 h cubed plus 35 h squared minus 180 equals 0. (b) Use the solution from part (a) to solve this problem. The width of a rectangular box is five times the height, and the length is 7 inches more than the height. If the volume is 180 cubic inches, find the dimensions of the box. h plus 7 h 5h

Problem 2 Link AB has an angular velocity of $\omega_{AB} = 5$ rad/s, and angular acceleration of $\alpha = 2$ rad/s$^2$. The length of AB is 0.5 m and the length of BC is 1.25 m. The angles are shown in the image. Determine the following: A. Angular Velocity of link BC. B. Velocity of the slider at C (vector format is acceptable). C. Acceleration of the slider at C (vector format is acceptable). $\omega, \alpha$ B A 30° 45° C Start with then end you know information on, in this case that is A.

Problem 1 I need Problem 2. Thanks Solely based on the formulas $a^n u[n] \rightarrow \frac{1}{1 - az^{-1}}$ and $(n+1) a^n u[n] \rightarrow \frac{1}{(1 - az^{-1})^2}$ determine the $z$-transforms of the following sequences: (a) $x[n] = (n-1)u[n]$ (b) $x[n] = (-1)^n 2^{-n} u[n]$ (c) $x[n] = \cos(\omega_0 n) u[n]$ (d) $x[n] = (nr^n \cos \omega_0 n) u[n]$ (e) $x[n] = Ar^n \sin(\omega_0 n + \phi) u[n]$ Hint: Remember that $\cos$ and $\sin$ yield expressions in terms of complex exponential functions. Problem 2 Given that $\omega_0$, $r$, $A$ are all real, put the $z$-transforms you obtained in Problem 1 in the form of single fractions with only real coefficients. Hint: $a + a^* = 2 \text{Re}(a)$; $a - a^* = 2j \text{Im}(a)$; $\overline{a} = a$; $aa^* = |a|^2$; $(\alpha \beta)^* = \alpha^* \beta^*.$
