Answer: A=12
Explanation:
4.5
The amount of chemical remaining after twelve seconds in the first reaction is:
A = 12 - 0.5(12)
= 12 - (6)
= 6
In the dissolved reaction, the amount of chemical loses half of itself every four seconds. This is the same thing as dividing by 2 every four seconds.
This is an exponential decay, so the amount of chemical divides by 4 every eight seconds, and by 8 seconds every twelve seconds. The amount remaining after twelve seconds in the second reaction is:
A' = 12/8
= 3/2
= 1.5
The difference between the amounts of chemical remaining is:
6 - 1.5 = 4.5
Therefore, A is 4.5 g greater than A' after twelve seconds.
Answer:

The true statement about white-tailed deer is that they no longer live in an area they were once found; option D.
<h3>What is true of the White-tailed deer of the Puget sound?</h3>
The passage describes two types of Deer found in the area called Puget Sound.
The passage indicates that the white-tailed deer together with the black-tailed deer were the once the two prevalent deer of the Puget Sound.
However, only the black-tailed deer are more common now as the white-tailed deer has been restricted to the low marshy areas and Islands of the Columbia river.
Although the reason for this decline was not given, but it can be inferred that environmental changes led to the decline of the white-tailed deer in the area of Puget sound.
When species of organisms are not able to fully adapt to changes in their environment, the population of that species of organism will reduce until they eventually are no more found in that environment.
In conclusion, white-tailed deer are no longer common in the Puget Sound.

Answer:
I would assume that we would want to know how much and the type of precipitation to know if the anything is changing within our climate. We would most likely need to know how much precipitation we are getting a year to see if it's less or more the next years to come.
