center of gravity...

y= (-2x^2 / 169) + (4x / 13) + 3 (0<x<26 < = less that or equal to)

actual distance the center of gravity travels is approx. 26.4046

evaluate the definite integral by first using the subsitution --> tan u = (-4 / 169)x + (4 / 13) and then integrate sec^3u


Thanks guys ..yous are much help
