 This usually requires no change to takeoff for high-rises
 since electrical riser rooms are themselves fire-rated.

 ### Bi-Directional Amplifier (BDA)
 Used to facilitate radio (usually cellular) communication
 where it is inhibited by the facility structure.
 Consists of a donor antenna, bi-directional amplifier,
 and any number of remote units
 where hard-wired connections to the BDA can be made.
 ### Distributed Antenna System (DAS)
 Used to extend wireless communication throughout a facility.
 While active DAS can be said to _require_ a BDA system,
 in practice a "DAS System" almost always refers
 to all the equipment required for its operation.

 ### Are Hotels Multifamily Dwellings?
 > [!info]
 > This question also applies to student housing and similar occupancies.
 Whether hotel rooms are dwelling units
 and thus whether are hotels are multifamily dwellings per the NEC definition
 is contingent on the AHJ's interpretation
 of the requirement for permanent provisions for cooking.
 > [!cite] [[nfpa-70_100_definitions#Dwelling Unit.| NEC Article 100]], emphasis added

 Anecdotal evidence from [reliable forums](https://forums.mikeholt.com/)
 suggests that a cord-and-plug connected microwave
 is generally not interpreted to meet the requirement,
 however I'm not separating these, at least for now.

 ### Expected Coin
 Estimate expected value and volume for a randomly selected coin.

 $$
 V = \pi r^2 \times h
 $$
 ### Expected Monetary Density
 $$
 D = \frac{M_{E}}{V_{E}} \times E
 $$
 where
 * $M_{E}$ = Monetary value of the Expected Coin
 * $V_{E}$ = Cylindrical volume of the Expected Coin
 * $E$ = Packing efficiency
 > [!note] Estimating Packing Efficiency
 > Estimating $E$ will be tricky.
 ### Volume of the "Bowl"
 Let the "bowl" be a hemispherical volume with radius $r_{B}$ enclosing all coins.
 The volume of the bowl $V_{B}$, the liquid volume occupied by the coins, is given by
 $$
 V_{B} = \frac{2}{3} \pi  r_{B}^3
 $$
 ### Total Monetary Value
 The total monetary value of all coins in the bowl is given by
 $$
 \begin{align*}
 M_{B} &= V_{B} \times D
