The table below shows the amount of a radioactive compound remaining after X years Sarah is compiling the data into a lab report
Murrr4er [49]

Answer:

  A. the y-intercept of the graph is 900, and as X increases, f(x) approaches 100.

Step-by-step explanation:

The table can be described by the function ...

  f(x) = 100 +800·2^-x

This is an exponential decay (not a constant-rate decay) from a y-intercept of 900 down to a minimum value of 100 (not zero).

The best description is that of choice A.

I'm assuming you're looking to find the expanded form of the number?

This number is in scientific notation. The easiest way to convert it to a normal number is to move the decimal place 14 to the right. I've attached a picture showing how to do this. You should get 630,000,000,000,000

There's a faster way to do this - notice that you need to move the decimal 14 to the right, and there's one number already after the decimal place. Therefore, 13 places will be filled with zeros. So, just write out 63 and add 13 zeros.

For more general help on scientific notation, check out these videos: https://www.khanacademy.org/math/pre-algebra/pre-algebra-exponents-radicals/pre-algebra-scientific-notation/v/scientific-notation-old

Hope that helps! Feel free to message me or leave a comment if I can clarify anything :)
