A plane loses altitude at the rate of 5 meters per second. It begins with an altitude of 8500 meters. Write an equation that represents this information.

Find the area of the region that is inside r=3cos(theta) and outside r=2-cos(theta). sketch the curves.

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.
