If the half-life is 5 minutes, then 30 minutes is equivalent to 6 half-lives. So, after six successive half-lives, the 400 mg of the radioisotope would have a mass of 400(0.5)⁶ = 6.25 mg.
Thus, A would be the correct answer choice here.
Y=−8x+5
The slope of the line is m=−8
The equation of the line in the slope-intercept form is y=−8x+5
I’m pretty sure that c is the interview because A, B, and D are all the formats used in every AP test i’ve taken
I think I c the answer mate ;)
Both the areas observed participated in significant long-distance trade.
