Answer:
The correct answer is 10.
Explanation:
The pH of a solution can be calculated by using the following formula:
![pH = - \log_{10} [H^{+}]](https://tex.z-dn.net/?f=pH%20%3D%20-%20%5Clog_%7B10%7D%20%5BH%5E%7B%2B%7D%5D)
(1)
Where ![[H^{+}]](https://tex.z-dn.net/?f=%5BH%5E%7B%2B%7D%5D)
is the concentration of hydrogen ions in the solution.
If we know that solution D has a hydrogen ion concentration of 
, then the pH of the solution is:
Hence, the correct answer is 10.
I got this answer from someone else but it should answer your question
About 6 days
Step-by-step explanation:
Here the function that shows the population of fish after x weeks,
Where b is any unknown,
If b = 3,
Then, the function is,
Which is a exponentially increasing function,
That having y-intercept = (0,1)
And, horizontal asymptote,
y = 0
End behavior of the function:
As ,
As ,
Thus, by the above information we can graph the given relation.
Now, For at least 100 fish in the pound,
By taking log on both sides,
Thus, after 0.8567 weeks (approx) the fish on the pound will be at least 100.
1 week = 7 days,
0.8567 weeks = 5.9969 days ≈ 6 days
Hence, after 6 days (approx) the fish on the pound will be at least 100.
If a paint chip were to match a paint chip from a known sample, there is only a 1 inch 33,000 chance that the paint chip came from another vehicle. While this doesn't link a particular vehicle to a paint chip without question, it does mean that there is a very good chance that a paint chip comes from that car if the samples match in<span>composition and other factors.</span>
