The system below is homogeneous so is consistent and has more unknowns than equations so has an infinite number of solutions. Solve this system by specifying appropriate free variables, solving for the other variables in terms of the free ones then expressing the general solution as a sum of scalar multiples of fixed column vectors. $x_1 - x_3 + x_4 + x_6 = 0$ $3x_1 + 3x_2 - 3x_3 + 3x_5 + 6x_6 = 0$ $2x_1 + x_2 - 2x_3 + x_4 + 2x_5 + 3x_6 = 0$

Determine whether the following conditions will increase or decrease carrying capacity for the given population. Increases Carrying Capacity Two sets of apartments are constructed along the riparian zone of a stream, causing silt and dirt to cloud the waters and suffocate fish and freshwater mussels in the stream. A researcher triples the number of bird boxes in an area populated by blue birds, obligate cavity nesters that cannot make their own cavities and rely on vacant cavities for nesting. Members of a local nonprofit organization add large woody debris to a local stream, providing more locations for salmon and trout to hide, feed, and breed. An area of forest containing a prime owl habitat is cleared to make room for a new subdevelopment. Decreases Carrying Capacity

In Problems 25-28 consider the two-compartment model for two tanks with respective volumes $V_1$ and $V_2$. $\frac{dC_1}{dt} = \frac{q}{V_1}(C_\infty - C_1)$ (8.93) $\frac{dC_2}{dt} = \frac{q}{V_2}(C_1 - C_2)$ (8.94) where $C_1(t)$ is the concentration in the first tank and $C_2(t)$ is the concentration in the second tank, and $q$ is the volume of water flowing between the two tanks in one unit of time. 25. When we analyzed (8.93) and (8.94) in the main text we assumed that $V_1 \neq V_2$. Now consider how the analysis must be modified if $V_1 = V_2$, and $C_1(0) = C_2(0) = 0$. a. Show that $C_1(t) = C_\infty(1 - e^{-qt/V_1})$ and $C_2(t) = C_\infty \left(1 - \left(1 + \frac{qt}{V_1}\right)e^{-qt/V_1}\right)$ b. Show that $\lim_{t \to \infty} C_1(t) = C_\infty$ and $\lim_{t \to \infty} C_2(t) = C_\infty$.
