Carbon 14 is a radioactive isotope that decays at a rate proportional to the amount present and has a half-life of 5,730 years. If the original amount present of carbon 14 were 10 grams, how much would be left after 1,000 years?

8.861 grams

Step-by-step explanation:

X = 10 × ½^(t/5730)

At t = 1000

X = 10 × (½)^(1000/5730)

X = 8.860622295 grams

in 1995, potato plants were taken into space aboard the space shuttle columbia.

step-by-step explanation:

you ignore the remainder, therefore the answer is y = x+2

step-by-step explanation:

you have to divide the denominator by the numerator. you can use synthetic division or long division.

[-5] .     1 .     7 .     11

x + 2 + 1/x+5
