Askyrocket is launched from a 6-foot-high platform with an initial speed of 200 feet per second. the polynomial —16t^2 + 200t + 6 gives the height in feet that the skyrocket will rise in t seconds. how high will the rocket rise if it has a 5 second fuse?

Anew test for ra is being developed. the test is administered to 750 patients with ra and 750 without ra. for the sake of the question, assume the prevalence of ra in this population is 50%. of the 750 patients with ra, 575 have a positive result. of the 750 patients without ra, 150 have a positive result. what is the positive predictive value of the new test? a575/(575+150) b. 600/(600+ 150) c. 575/(575+125) d. 600/(600+ 125)
