Answer:
If the ABCD is rectangle, find the mZCAB
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.
I hope it helps you!
Answer:
5 + a
A: ---------
a - 1
Step-by-step explanation:
3+x 3 + a + 2
f(x) = ---------- becomes f(a + 2) = ------------------
x-3 a + 2 - 3
5 + a
when a + 2 is substituted for x. This last result simplifies to ------------
a - 1
which matches Answer A.
I would say A, because RST = VUT. Also, that would make the most sense... That is just me...
