Carbon-14 is an element which loses 10% of its mass every 871 years. The mass of a sample of carbon-14
can be modeled by a function, M, which depends on its age, t (in years).
We measure that the initial mass of a sample of carbon-14 is 960 grams.
Write a function that models the mass of the carbon-14 sample remaining t years since the initial
measurement.

i’m on khan academy and i got it wrong so that it would give me the answer and the answer is M(t)=960(9/10)^t/871

Step-by-step explanation:

1; 35 is the ratio

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
