Answer:
y-intercept = 4
x-intercept = 2
Step-by-step explanation:
you can divide the equation through by 4 and change into the y=mx+c form to find c, the y intercept so the y-intercept = 4.
for the x intercept make the y=0 (because the coordinate point where the line crosses the x axis must have y=0) and then you get 8x=16 so x=2
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>
