Step-by-step explanation:
im late sorry
The tree died about 3357 years ago.
Explanation:
The half life of carbon - 14 is given by
where 
Substituting these values in the above equation, we get,
Taking In on both sides of the equation, we get,
Since, only 66% of Carbon - 14 remains after the time T.
Thus, we have,
Taking In on both sides of the equation, we get,
Thus, the tree died about 3357 years ago.
Answer:
6.25%
Step-by-step explanation:
discount/ normal price
5/80
And we are trying to find out the percentage, so
x/100
Set the 2 equations equal to each other
5/80=x/100
Cross multiply
80x=500
Divide by 80 on both sides
x= 6.25
Your going to have to use the distance formula for these questions which is the square root of (x sub 2 - x sub 1) + (y sub 2 - y sub 1). For number 1 your coordinates are (-5,5) and (1,-2). Substituting these values into the formula your answer for number 1 is 9.2.
