You and your teammates discuss for a moment and decide to try to activate reagent X. Searching around the lab, you find a piece of equipment with the radioactive symbol on it. It is connected to a monitor which reads: I'For optimal radiation, set position 2 of sample In domain 1 S a: S 10 within precision 0.1 such that z 21t1((:n2)2 +16) =0.\" Looking back at the machine, you observe a dial which appears to adjust the position of a radioactive source relative to the dish In the enclosure. What value do you set the dial to? Number
