A snow skier launches off a ramp that is 10 feet tall. The upward velocity of the skier is 12 ft per second. A. Write an equation that models the height H (in feet) of the skier as a function of time T (in seconds).
B. After how many seconds does the skier land? C. When does the skier reach maximum height? D. What is the maximum height reached?
E. With the same upward velocity, would the skier stay in the air longer launching from a 8-foot ramp or 12-foot ramp?​

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

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
