Answer:
8978 grams
Step-by-step explanation:
The equation to find the half-life is:
N(t) = amount after the time <em>t</em>
= initial amount of substance
t = time
It is known that after a half-life there will be twice less of a substance than what it intially was. So, we can get a simplified equation that looks like this, in terms of half-lives.
or more simply
= time of the half-life
We know that = 35,912, t = 14,680, and
=7,340
Plug these into the equation:
Using a calculator we get:
N(t) = 8978
Therefore, after 14,680 years 8,978 grams of thorium will be left.

To find the value of q, we need to find d(-8). Put another way, we need to find the value of d(x) when x = -8
So this means q = 0. Note that -0 is just 0.
===========================================
The value of r will be a similar, but now we use f(x) this time.
Plug in x = 0
Therefore, r = 2.
===========================================
For s, we plug x = 10 into f(x)
So s = 3.
===========================================
Finally, plug x = 10 into d(x) to find the value of t
A shortcut you could have taken is to note how d(x) = -f(x), so this means
d(10) = -f(10) = -9 since f(10) = 9 was found in the previous section above.
Whichever method you use, you should find that t = -3.
===========================================
<h3>In summary:</h3><h3>q = 0</h3><h3>r = 2</h3><h3>s = 3</h3><h3>t = -3</h3>
