What is the algebraic rule for a figure that is rotated 270° clockwise about the origin? A. RO,–270°(x, y) → (–y, x) B. RO,–270°(x, y) → (x, –y) C. RO,270°(x, y) → (–x, –y) D. RO,270°(x, y) → (–y, –x) Please select the best answer from the choices provided A B C D

Radii ok and nl are perpendicular to om because of the radius-tangent theorem. by definition of perpendicular, angles kom and lnm are right angles. this means that triangles kom and lnm are right triangles. angle lmn is common to both right triangles, so by the triangles kom and lnm are similar.

What expression is equivalent to (84+16)

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.
