Answer:
They are right, the time calculated using the exponential decay equation is 1948.6 years.
Step-by-step explanation:
The time can be calculated using the exponential decay equation:
(1)
<u>Where</u>:
N(t): is the quantity of C-14 at time t
N₀: is the initial quantity of C-14
λ: is the decay constant
The decay constant is:
(2)
By entering equation (2) into (1) and solving for t, we have:

Therefore, the time of the scrolls estimated by the archeologists is right, since the time calculated using the exponential decay equation is 1948.6 years.

Answer:
20 pounds / in^2
Step-by-step explanation:
Presssure = Force in pounds / Area in square inches.
Force: 60 pounds (given)
Area: 3 in^2 (given
Pressure = 60/3 = 20 pounds / square in
Multiply price per pound by total pounds:
2.50 x 3.5 = 8.75
Total cost = $8.75
