Eiffel Tower = 1063 ft [| http://en.wikipedia.org/wiki/Eiffel_Tower] Empire State Building = 1250 ft [] Space Needle = 605 ft [] original Arch equation = y= -.0064(x^2)+630

__**Space Needle**__ 630/605 = 1.04 1/1.04 = .96 S(x.y)->(.96x, .96y) (y/.96)= -.0064x^2/(.96)+630

y/.96(.96)= -.0064x^2/(.96)+630(.96)
 * y= -.0067x^2+604.8**---> __**space needle sized arch!**__

__**Empire State Building**__ 630/1250 = .504 1/.504 = 1.98 S(x,y) --->(1.98x, 1.98y) (y/1.98)= -.0064x^2/(1.98)+630

y/1.98(1.98) = -.0064x^2/(1.98)+630(1.98)
 * y= -.0032x^2+1247.4**--> __**empire state building sized arch!**__

630/1063 = .59 1/.59 = 1.69 S(x,y)-->(1.69x, 1.69y) (y/1.69) = -.0064x^2/(1.69)+630
 * __Eiffel Tower__**

y/1.69(1.69) = -.0064(x^2)/(1.69)+630(1.69)
 * y = -.0038(x^2)+1064.7** ---> __**eiffel tower sized arch!**__
