Answer:
Approximately 3 grams left.
Step-by-step explanation:
We will utilize the standard form of an exponential function, given by:
In the case of half-life, our rate <em>r</em> will be 1/2. This is because 1/2 or 50% will be left after <em>t </em>half-lives.
Our initial amount <em>a </em>is 185 grams.
So, by substitution, we have:
Where <em>f(t)</em> denotes the amount of grams left after <em>t</em> half-lives.
We want to find the amount left after 6 half-lives. Therefore, <em>t </em>= 6. Then using our function, we acquire:
Evaluate:
So, after six half-lives, there will be approximately 3 grams left.
Line a and b are perpendicular
We have to express the ratio 1 : 3.5 in the form p:q where p and q are whole numbers.
Consider the ratio of 1 and 3.5,
1 : 3.5 =
=
Reducing the above fraction to its lowest form.
So, we get
Therefore, the ratio 1 : 3.5 is expressed as
where 2 and 7 are the whole numbers.
This is crazy. If I'm reading this right (I'm not sure why there are spaces put in between some of those numbers like there is), I'm getting that the answer is
-1079.242293. But again, those spaces are throwing me off. I eliminated the spaces between the numbers while I was performing the operations in order.
