b 2 d The length of arc s of a curve from x = a to x = b is given by the formula 5 =I 1 + [d:] dx. The cable of a bridge can be described a 300 ft by the equation v = 0.26X3l2 from x = O to x = 300 ft. Find the length of the cable. s = feet (Round the nal answer to the nearest integer as needed. Round all intermediate values to the nearest ten-thousandth as needed.)
