BARS::14 Mileages on One Sign on Parker Dam Road in California

This road sign is on Parker Dam Road across the Colorado River from Parker, Arizona, in California.

The road sign says...

RoadHacker first found this sign during December of 2006 and a BARS was created. As a result of finding the sign a second time, 2006 BARS was updated to include a rsAgeEval=48 and a rs42Eval.

RoadHacker photographed the sign a 2nd time on 27 May 2008. This BARS was created containing the following road sign evaluations: rsAgeEval=50, rsPiEval and rsPhiEval.

   the numbers are:   4.5, 5, 6.5, 7, 8, 8.5, 11, 12, 
                     12.5, 14, 14.5, 14.75, 25, 29

   River Lodge Too?

   A = ((11 - 8) * (29 - 25)) / (14.75 - 14.5) = 48
   B = (12.5 - 8.5) - (6.5 - 4.5) + (7 - 5) - (14 - 12) = 2

   rsAgeEval:  A + B = 50
   * RoadHacker took this picture on his last day being 50 years young.

   A = (6.5 - 4.5) * ((12.5 - 8.5) * (14.75 - 14.5)) = 2
   B = 12 + 8 - 14 + sqrt(29 + 7) - sqrt(5 * sqrt(25)) = 7

   rsPiEval:  (A * 11) / B = 22 / 7 = Pi (3.14)
   * 22/7 approximates Pi (3.14) rounded to nearest hundredth

   C = sqrt(29 + 7) / (14 - 11)! = 1
   D = sqrt(sqrt(12 + 8 + sqrt(sqrt(25) * 5))) = sqrt(5)

   rsPhiEval:  (C + D) / A = (1 + sqrt(5)) / 2 = Phi (1.16803399)
   * Phi is the golden ratio and it approximates 1.61803399

The following math was discovered on 1 May 2009 after this BARS was selected as one of the BARS of the Week for Week #15 of the spring 2009 semester.

   the numbers are:   4.5, 5, 6.5, 7, 8, 8.5, 11, 12, 
                     12.5, 14, 14.5, 14.75, 25, 29

   A = 4.75 - 14.5) = 1/4
   B = 6.5 - 4.5 = 2
   C = 12.5 - 8.5 = 4

   the numbers become:  5  7  8  11  12  14  25  29  1/4  2  4

   rsAgeEval:  (7 - 5)*(11 - 8)*(14 - 12)*(29 - 25) + 2 + 4 * 1/4 = 51
   * MathBabbler was 51 years young when he found this equation
