Use the telescoping series method to find \[ \sum_{n=5}^{\infty} \frac{1}{(n-1)(n-2)} \]
Assignment Heat through conical section Heat flows through a conical section of wall, whose diameter is given by the formula: $D = ax$. Given: a = 0.25 x_1 = 50 mm x_2 = 250 mm T_1 = 400K T_2 = 600K 1 1 point Area of the section at $x_1$ [m$^2$] 2 1 point Area of the section at $x_2$ [m$^2$] 3 5 points Assuming a k value of 3.40 (W/m.K), calculate the heat flow [kJ/s] through the section (ignore the effects of convection). The hot and cold temperatures are 580K and 399K respectively. 4 1 point If convection were included in the question, heat transfer would have been Higher Lower The same Impossible to tell without more information
Find the triple integral \(\iiint_E xy\,dV\) by converting to cylindrical coordinates. Assume that E is the solid enclosed by the surfaces \(z = 4 - x - y\) and \(z = 6 - x - y\) and the cylinder \(x^2 + y^2 = 9\). (Use symbolic notation and fractions where needed.) \(\iiint_E xy\,dV = \)

The following 2DOF system is given, as shown in Figure 1. The stiffness and mass moment of inertia parameters are given as follows: $K_1$=15 N-m/rad, $K_2$= 20 N-m/rad, $K_3$= 15 N-m/rad, $J_1$= 10 kg-$m^2$, and $J_2$= 10 kg-$m^2$ If this system is given the following initial conditions, $\theta_1(0)$ =0.1 rad, $\dot{\theta}_1(0)$ = 0, $\theta_2(0)$=0.3 rad, and $\dot{\theta}_2(0)$ = 0. Please use modal analysis approach to find the solution for $\theta_1(t)$ and $\theta_2(t)$.
a) a given system is represented by the following input output formula y(n)=T[x(n)]=n x(n). Show whether the system is linear or nonlinear and time varying or not. b) a LTI system is characterized by h(n)=$a^n$ u(n). Classify this system if causal or non-causal an stable or unstable.
