MHF 4U1- Date: 8.4 Inequalities of Combined Functions Example: Let \(f(x) = x + 4\) and \(g(x) = (x + 2)^2\). a) Graph the functions on the same set of axes using different colours. Identify the points of intersection. 6 -4 -2 2 4 6 X -2 -4 -6 b) Identify the regions (values of x) where \(f(x) > g(x)\) and \(f(x) < g(x)\). Method 1: Compare the functions visually using the graphs.

Steam flowing through a long, thin-walled 2" ID (0.0508m) pipe maintains the pipe wall at a uniform temperature of 443K. The pipe is covered with an insulation blanket made of calcium silica that is 2" thick (0.0508m). The outside is covered with a thin 316-grade stainless steel metal jacket. The entire outer surface is exposed to air at T=347K, wind velocity is 4.5m/s, h=32W/m^2-K. For the prescribed conditions, what is the total heat loss from the pipe? What is the outer surface temperature of the stainless steel metal jacket? Please include ALL calculations for every step.

2. (25%) Consider the system spring system shown. A massless, rigid slider is constrained to move horizontally. Two spring elements, each with stiffness $\frac{k}{2}$ connect the left side of the slider to a fixed wall. A single spring element with stiffness $k$ is attached to the right side of the slider. The system is originally at rest. Then, an unknown force $F_{4x}$ is applied to the fourth node which causes to translate horizontally by a known distance $u_4 = \delta$. Please answer the following questions. a) Set up the system of equations as $F = Kd$. Solve for the unknown displacement $u_3$ in terms of $\delta$. b) Using the result from part (b), determine the unknown force $F_{4x}$ in terms of $k$ and $\delta$.
