Triangle ABC is rotated 90 degrees about the origin to form triangle A’B’C’. Which composition of transformations on triangle ABC will result in a triangle in the same position as triangle A’B’C’? T(–4, 0) ry = x ry-axis ry = x ry-axis T(0, 4)

Darla claims that the first periodic table developed by mendeleev was not completely accurate, so it is not useful at all. harmony argues that it establish the periodic table we use today, making it more credible. who is correct and why? darla is correct, because a model that has any mistakes should be thrown out. darla is correct, because a good model would not need to change. harmony is correct, because mendeleev’s model had all of the information correct in the first version. harmony is correct, because mendeleev’s model made predictions that came true.
