Triangle QNP was dilated by a scale factor of One-third about point P. It was then transformed in another way to produce Triangle Q prime N prime P prime.

On a coordinate plane, triangle Q N P has points (negative 1, 0), (negative 7, 9), (negative 1, 9). Triangle Q prime N prime P prime has points (6, 1), (9, 3), (9, 1).

Which identifies the transformation that occurred after the dilation?

a 90 degrees clockwise rotation about the origin

a 180 degrees clockwise rotation about the origin

a reflection across the x-axis

a reflection across the y-axis

Astudent is determining the influence of different types of food on the growth rate of spiders. she feeds one group of spiders two caterpillars twice a week. the other group received similarly-sized beetles twice a week. she records the amount of time required for individuals to reach sexual maturity. her hypothesis is that the spiders feeding on caterpillars will have a faster growth rate because caterpillars have a higher protein content compared to beetles. in this experiment, what is the dependent variable? spiders assigned to different feeding groups. time required to reach sexual maturity number of prey items fed twice a week. growth rates of each group.
