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

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
