A vertical sag parabolic curve connects a -6% grade to a +1% that meets at station 12+720 with an elevation of 63m. The change in grade is 0.7% every 20m. What is the stationing and elevation of the lowest point of the curve? Group of answer choices 12+791.43; Elevation 63.86m 11+852.72; Elevation 64.27m 13+003.24; Elevation 65.63m 14+283.32; Elevation 66.26m A 280m long sag curve connects a -13% grade to a +5% grade. The grader intersects at station 1+460 which elevation of 12.39m. Find the elevation of the first quarter point of the curve. Group of answer choices 19.25m 27.5m 23.07m 21.62m Curve having a radius of 155.42m has an intersecting angle of 36"45'. PC is at station 0+750. Find the right angle offset distance to station 0+825.50m. Group of answer choices 16.48m 17.98m 19.64m 18.55m The areas in cut of two irregular sections 65m apart are 29 square meters and 68 square meters respectively. Base width is 10m side slope of 3:2. Using Prismoidal correction formula, find the corrected value of cut in cu.m between the two stations. Group of answer choices 3571.83 3807.76 3719.42
