BARS::I-8 East and West Arrows at Freeman Road in Arizona

These I-8 road signs are on Freeman Road in Arizona.

The I-8 road signs say...

   +------------+ +------------+
   |    West    | |    East    |
   +------------+ +------------+
   | Interstate | | Interstate |
   |   Arizona  | |   Arizona  |
   |      8     | |      8     |
   +------------+ +------------+
   |      ^     | |     -->    |
   |      |     | |            |
   +------------+ +------------+

   This picture was taken looking North and the 
   East --> arrow is pointing in the correct direction.

   Choose all, if any, that get the West arrow pointing west.

   A:  rotate the west arrow 90° clockwise
   B:  rotate the west arrow 270° clockwise
   C:  rotate the west arrow 90° counter-clockwise
   D:  rotate the west arrow 450° counter-clockwise
   E:  rotate the west arrow as follows:
       1) clockwise 180°
       2) counter-clockwise 360°
       3) clockwise 270°

The following is from the Wikipedia.

   The SI prefix for 10008 is yotta (Y), 
   and for its reciprocal yocto (y).

GDT::BAB::About the Number 8 (Eight)

Updated::2009.05.06

MathBabbler added rsStateEval to the BARS system on 3 May 2009.

   the numbers are:  8  8

   rsStateEval:  spf(8) * 8 = 48
   * Arizona is the 48th state of the United States

   observe...
      spf(n) outputs the sum of the prime factors of n
      spf(8) = 2 + 2 + 2 = 6

   dup(8); the numbers become:  8  8  8

   another rsStateEval:  cuberoot(8 * 8)! * cuberoot(8) = 48

   more math:  sqrt(8 * 8) = 8

   more math:  spf(8) + cuberoot(8) = 8

   dup(8); the numbers become:  8  8  8  8

   another rsStateEval:  8 * 8 - 8 - 8 = 48

   dup(8); the numbers become:  8  8  8  8  8 

   another rsStateEval:  cuberoot(8) * 8  * cuberoot(8) + 8 + 8 = 48

   more math:  8! / spf(8)! = spf(8) * 8 + 8

   dup(8); the numbers become:  8  8  8  8  8  8

   another rsStateEval:  8 + 8 + 8 + 8 + 8 + 8 = 48
Update::2013.11.25

rsCardinalityEval and the spd(n) function were added to the MBNA since this BARS was last updated.

   the numbers are:  8  8

   rsCardinalityEval:  sqrt(8 / cuberoot(8)) = 2
   * There are two numbers used in the BARS.

   rsCardinalityEval:  sqrt(cuberoot(8 * 8)) = 2
   * There are two numbers used in the BARS.

   rsCardinalityEval:  cuberoot(8! / spf(8)!) = 2
   * There are two numbers used in the BARS.
   * spd(n) = the sum of the proper divisors of n
     domain: n must be a composite number
   * spd(8) = 1+2+4 = 7

   rsAgeEval:  8 * spd(8) = 56
   * MathBabbler was 56 years young when he added this equation.
