The value of the limit expression 
is 9, and it means that the function approaches 9, as x approaches 3.
<h3>How to evaluate the limit?</h3>
The limit expression is given as:
This means that we determine the value of the function as x approaches 3.
So, we have:
Limit = √(3^2 + 7) + 5
Evaluate the square
Limit = √(9 + 7) + 5
Evaluate the sum
Limit = √16 + 5
Evaluate the square root
Limit = 4 + 5
Evaluate the sum
Limit = 9
Hence, the value of the limit is 9

Answer:
C.) Heat dose not flow because both substances are at the same temperature.
Explanation:
To solve this problem, first we have to determine the z statistic. The formula is
where x is the test point which is 8.019, the mean is 8 mph, s is the standard deviation which is 3.813 and n is the number of data which is 1114. Then,
Next, we find the p-value for the particular z. p-value is used in hypothetical test. Using a wind turbine would be the null hypothesis. From the standard normal table found in any statistics book, the p-value for z<0.17 is 0.5675. If the p-value is greater than 0.05, then you do not reject the null hypothesis.
Therefore, the landowner could use a small turbine at the site.
