The half-life of a certain isotope of uranium is 2,315 years. how much of an
initial sample of 30 grams would be left after 10,000 years?

The answer to your question is: there would be 1 g approximately

Step-by-step explanation:

half life U 2315 years

initial sample = 30 g

mass after 10 000 years

                   30 g    today

                   15 g      2315 years

                   7.5 g   4630 years

                   3.75 g  6945 years

                  1.88 g     9260 years

                  0.94 g   11575 years

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
