Determine the eccentricity, the type of conic, and the directrix for r =2.1/1+0.7cod theta

Which inequality has a dashed boundary line when graphed ?

Suppose that 3% of all athletes are using the endurance-enhancing hormone epo (you should be able to simply compute the percentage of all athletes that are not using epo). for our purposes, a “positive” test result is one that indicates presence of epo in an athlete’s bloodstream. the probability of a positive result, given the presence of epo is .99. the probability of a negative result, when epo is not present, is .90. what is the probability that a randomly selected athlete tests positive for epo? 0.0297

Are the corresponding angles congruent? explain why or why not.
