BASEBALL Tonisha hit a baseball into the air with an initial upward velocity of 48 feet per second. The height I feet of the ball above the ground can be modeled by h -167 +48 + 2. where is the time in seconds after Tonisha hit the baseball. Find the time it takes the ball to
reach 38 feet above the ground.

In simplified exponential notation, the expression a^2•a^-3•a 1/a 0

Which of these triangle pairs can be mapped to each other using two reflections?

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
