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°## Help

rsStateEvalto 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

rsCardinalityEvaland thespd(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.
