The amount of substance left of a radioactive element of half life,
after a time, t, is given by:
Given that <span>potassium-40 has a half life of approximately 1.25 billion
years.
The number of years it will take for 0.1% of potassium-40 to remain is obtained as follows:
Therefore, </span><span>the maximum age of a fossil that we could date using 40k is
12.5 billion years.</span>
Answer: 6
Step-by-step explanation: you multiply x4 and -3 because the parenthesis and then you add.
Answer:
you can use a website called calculator soup the answer is -9/14 please mark me branlist
Step-by-step explanation:
You would get rid of the 2.5 by subtracting 2.5 on both sides, then the equation becomes
3x=3.6
solve for X by dividing 3 on both sides
Answer:
<h2><em>
<u>Domain = (-∞, ∞) Range = (-∞, ∞) </u></em></h2><h2>
Step-by-step explanation:</h2><h2>The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.</h2><h2>Interval Notation:</h2><h2>(−∞,∞)</h2><h2>Set-Builder Notation:</h2><h2>{x|x∈R}</h2><h2>The range is the set of all valid y</h2><h2>values. Use the graph to find the range.</h2><h2>Interval Notation:</h2><h2>(−∞,∞)</h2><h2>Set-Builder Notation:</h2><h2>{y|y∈R}</h2><h2>Determine the domain and range.</h2><h2>Domain: (−∞,∞),{x|x∈R}</h2><h2>Range: (−∞,∞),{y|y∈R}</h2><h2>image of graph</h2><h2 />
