A rollercoaster track consists of a series of vertical curves.
Near the top of one of these curves, the track enters a tunnel, where passengers ride in
the dark for a short duration. The parabola in the graph represents the rollercoaster
track,
The vertex of this parabola is at (7.5. 21), and another point on the track is at (0.9).
A steel beam is part of the supporting structure of the rollercoaster track. The beam is
attached to the framework at the points (0.12) and (12, 19). determine the two equations of the parabola (quadratic function) and line

Will mark brainliest, , and rate to only chrislaurencelleenzo is making a scale drawing of the rectangle below. ~imageenzo says that he can draw an enlarged rectangle that is 16 centimeters by 13 centimeters. which explains whether enzo is correct? enzo is correct because he used a factor of 2 to enlarge the rectangle. enzo is correct because he doubled one dimension and added the two lengths to get the other dimension. enzo is not correct because the enlarged rectangle should be 16 centimeters by 5 centimeters. enzo is not correct because he did not multiply the length and width by the same factor.
