Here's a graph that shows a system of equations for this scenario where I is the number of seconds since Chana and Josiah started skating and y is the distance in meters from the starting line. y (distance 80 line b:y= 3.1 60 40 line a: y = 10 = 2.1 20- + x (time) 5 10 15 20 25 What does point G represent in this context?

For f(x)=2x+1 and g(x)= x^2 -7, find (f•g)(x)

The swimming pool is open when the high temperature is higher than 20∘c. lainey tried to swim on monday and thursday (which was 3 days later). the pool was open on monday, but it was closed on thursday. the high temperature was 30∘c on monday, but decreased at a constant rate in the next 3 days. write an inequality to determine the rate of temperature decrease in degrees celsius per day, d, from monday to thursday.

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
