The table below represents the equation y= 500(1-0.052)^x , which represents the amount of a drug left in a patient's bloodstream over time. The y -values represent time in hours, and -values represent the amount of the drug left in milligrams. Part A: What is the initial dosage of the drug in milligrams?

Part B: How much of the drug has been eliminated after 4 hours? Show your work.

Part C: Find the amount of the drug left in the patient's system after 24 hours.

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.
