Along a long, straight stretch of mountain road with a 7.2 % grade, you see a tall tree standing perfectly plumb alongside the road. From a point 450 feet downhill from the tree, the angle of inclination from the road to the top of the tree is 6.2 degrees. Use the Law of Sines to find the height of the tree to the nearest tenth of a foot.

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.
