Carbon–14 is a radioactive isotope that decays exponentially at a rate of 0.0124 percent a year. how many years will it take for carbon–14 to decay to 10 percent of its original amount? the equation for exponential decay is at = a0e–rt.

18569.234 years

Step-by-step explanation:

Given : Carbon–14 is a radioactive isotope that decays exponentially at a rate of 0.0124 percent a year.

To Find: How many years will it take for carbon–14 to decay to 10 percent of its original amount?

Solution:

The equation for exponential decay is

= initial amount

A(t) = Amount after t time

Now we are supposed to find after how many years will it take for carbon–14 to decay to 10 percent of its original amount.

So,

r = 0.0124 % = 0.000124

Substitute the values in the equation:

Hence it will take 18569.234 years to decay to 10 percent of its original amount.

black lol

step-by-step explanation:

i can tell you jamal now has 3 cookies xd

tommy has 2.

this made me lol.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
