Gabe amodeo, a nuclear physicist, needs 60liters of a 40%acid solution. he currently has a 30 % solution and a 60% solution. how many liters of each does he need to make the needed 60 liters of 40% acid solution?

39.5 I think that's the answer I hope its right if wrong than I'm truly srry

You are dumb you will drop out of high school

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
