Select the correct answer. what is the value of this limit? a. b. c. d. e.
dlinn [17]

The value of the limit expression \lim_{x \to 3} \sqrt{x^2 + 7} + 5 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:

\lim_{x \to 3} \sqrt{x^2 + 7} + 5

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 \lim_{x \to 3} \sqrt{x^2 + 7} + 5 is 9

Describe how differences in water temperature and salinity affect deep water currents.
Virty [35]
When the water molecules of the ocean become heated, they expand. ... Since warmer water thus can hold more salt and other molecules than cold water; it can have a higher salinity. To relate this to ocean currents, the higher the salinity of ocean water, the more dense it becomes. THIS IS NOT FROM MY OWN WORDS, IF YOURE TYPING THIS DOWN PLEASE REPHRASE IT A BIT!! :)
