Question

PLEASE HELP!!!
Compounds A and B are used in an experiment.


The equation A=30,000(12)t represents the remaining amount of compound A, in milligrams, after t seconds. The table shows the remaining amount of compound B.


Time (sec) mg of B

1 12,000

2 6,000

3 3,000

What is the positive difference in the initial amount of each compound?


Enter your answer in the box.

Answer 1

Answer:  6000  is the difference between the initial amount of each compound.

Step-by-step explanation:

Since, The equation $A=30,000(12)^t$ represents the remaining amount of compound A, in milligrams, after t seconds.

Since initially t =0 sec,

So, the amount by A = $30000(12)^0=30000$

And, According to the given table, we can say that every second the amount by compound B is decreasing to its half.

If In one second the amount by compound B is 12000

therefore, initial amount = 24000

Thus, the total difference between the amount by A and B initially= 30000-24000=6000

Answer 2

Answer:

6000mg is the difference.
