An equal-tangent parabolic curve \( 800 \mathrm{ft} \) long has been selected to join the two tangents grade \( g 1 \) of \( -2.5 \% \) and \( g 2 \) of \( 4 \% \). Given the curve elevation at the end of this vertical curve (YEVC) \( 945.80 \) feet with a stationing \( 10+00 \), solve the Rate of Change \( (r) \) : Question 2 \( 0 / 1 \) pts An equal-tangent parabolic curve \( 800 \mathrm{ft} \) long has been selected to join the two tangents grade \( g 1 \) of \( -2.5 \% \) and \( g 2 \) of \( 4 \% \). Given the curve elevation at the end of this vertical curve (YEVC) \( 945.80 \) feet with a stationing 10+00, solve the curve elevation at the beginning of this vertical curve (YBVC): \( 998.14 \) feet \( 939.80 \) feet
