Highway engineers design a parabolic curve for an entrance ramp from a straight street to an interstate highway (see figure 64 on page 742 of your textbook). the vertex of the curve passes through (0, 0) and the parabola passes through (1000, + 800). find an equation for the parabola.

Danny draws a transversal, t, on two parallel lines ab and cd, as shown below: he makes the following table to prove that the alternate interior angles are equal: which is the missing justification? (6 points) corresponding angles formed by a transversal on parallel lines are supplementary. corresponding angles formed by a transversal on parallel lines are congruent. co-interior angles formed by a transversal on parallel lines are congruent. co-exterior angles formed by a transversal on parallel lines are congruent.
