Answer:
250
Step-by-step explanation:
14 x 4 = 56
56 divided by 2 = 28
<h2>7000 divided by 28 =
250 </h2>
Answer:
A
Step-by-step explanation:
The common difference is simply the constant we add/subtract each time. In this case, the common difference is 3/2 as can be seen from the recursive formula. In other words, each new
will be 3/2 larger than the previous.
The answer is A.
Answer:
The correct answer is:
Between 600 and 700 years (B)
Step-by-step explanation:
At a constant decay rate, the half-life of a radioactive substance is the time taken for the substance to decay to half of its original mass. The formula for radioactive exponential decay is given by:

First, let us calculate the decay constant (k)

Next, let us calculate the half-life as follows:

Therefore the half-life is between 600 and 700 years
So you multiply 2 1/3times 1 1/2 and you get 3 and 1/6
