Answer:

2 x 10^16

Step-by-step explanation:

1.3 x 10^-4 x n = 2.6 x 10^12

(1.3 x 10^-4 /1.3 x 10^-4) x n = 2.6 x 10^12/1.3 x 10^-4

n = 2 x 10^16

When dividing, subtract your exponents.

12 - (-4) = 16

Problem PageQuestion The mass of a radioactive substance follows a continuous exponential decay model, with a decay rate paramet

asambeis [7]

Answer:

Step-by-step explanation:

<u>Exponential Model</u>

The exponential model is often used to simulate the behavior of a magnitude that either grow or decay in proportion to the existing amount of that magnitude.

The model can be expressed as

$M=M_oe^{kt}$

In this case, Mo is the initial mass of the radioactive substance and k is a constant which value is positive if the mass is growing or negative if the mass is decaying.

The value of k is not precisely given in the question, we are assuming $k=-0.2$
