A company has determined their yearly cost function, in dollars, to be given by C(x) = 2,200x^5/2 / 6x^2 + 5x − 4 , when x pounds of product are made. Find the marginal cost (in dollars per pound) when 5 pounds of product are made. (Round your answer to four decimal places.) C'(5) = dollars per pound
Question B2 [20 marks] (a) Helium is contained in a piston-cylinder apparatus fitted with a spring as shown in Figure QB2. The spring has a spring constant of $k=10^5$ N/m and maintains the gas in mechanical equilibrium. The gas experiences a heat transfer interaction at a rate which is slow relative to the rate at which equilibrium can be established throughout the gas. Thus, the pressure and temperature are uniform throughout the gas at all times even though they are both changing with time throughout the process. The piston is frictionless and the spring can be modelled as a pure translational spring. Calculate the work transfer experienced by the gas as the pressure increases from $P_1 = 1.013 \times 10^5$ Pa to $P_2 = 3.039 \times 10^5$ Pa. (i) What is the temperature of the Helium in State 2 ($T_2$) if $T_1= 300$ K and $V_1 = 0.1 m^3$? (ii) Calculate the heat transfer experienced by the Helium.

4-37 Consider the following steady, incompressible, two-dimensional velocity field: $\vec{V} = (u, v) = (4.35 + 0.656x)\vec{i} + (-1.22 - 0.656y)\vec{j}$ Generate an analytical expression for the flow streamlines and draw several streamlines in the upper-right quadrant from x = 0 to 5 and y = 0 to 6.
Assignment – MT compensation 1. Sketch the root loci for the system whose open loop transfer function is given below. $G(s) = \frac{(s + 2)}{(s + 1)(s + 1 + j)(s + 1 - j)}$
