A cottage is purchased for $140 000. The cottage is expected to increase in value each year by 4.5%. The value of the cottage can be represented by $A(t) = 140000(1.045)^t$, where $A(t)$ is the value of the cottage and $t$ is the number of years after the purchase. Rounded to the nearest year, it will take the cottage years to be worth $225 000.

2. [Bilinear Transform] The transformation $s = 2(1 - z^{-1})/(z^{-1} + 1)$ was applied to an analog prototype to design a HPF with a cutoff at $3\pi/5$. The width of the transition band of the resulting digital filter, from stopband edge to cutoff, is $\pi/10$. What is the corresponding transition bandwidth of the analog prototype?

A protein catalyzes the following reaction and has a Michaelis-Menten constant of $K_M = 25 mM$ and a turnover number of $4.0 \times 10^7 s^{-1}$. The total enzyme concentration is $0.018 \mu M$ and the initial substrate concentration is $5.48 \mu M$. The enzyme has a single active site. Calculate the values of $V_{max}$ and $V_0$ for this enzyme. (6 pts total) $V_{max} = $ (3 pts) $V_0 = $ (3 pts) $2H_2O_2(aq) \longrightarrow 2H_2O(l) + O_2(g)$
