Answer:
First, in standard notation, we must define our zero.
In this case, would make sense to define the zero in the surface of the water.
(below is a number line so you can see the process to think this)
Then if the whale is swimming 60ft bellow the surface of the water, then the first position of the whale is:
-60
Now the whale goes up 30ft, then the new position of the whale is:
-60ft + 30ft = -30ft.
The correct option is A:
The equation is -60 + 30 = -30. The whale is 30 feet below the water's surface.
(you wrote that the equation was equal to +30 instead of -30 in the option A, i supposed that it was a typo)
Answer:
Tortured and kidnapped white colonists, and some started wars.
Answer: D: $5272.
Step-by-step explanation:
Considering that all of the information is given to you already, the only thing that you need to do is plugin 9 for n.
So the final equation will look like this: 
The answer comes out to $5272.46721451 but rounding that to the nearest dollar would be answer choice D: $5272.
It can be applied by making it sound more educated
The functions have been arranged in ascending order from the least to the highest value below
- 3x
- 3x + 8
- x^2
- x^2 + 6
- 4^x
- 4^x + 3
<h3>What is meant by ascending order?</h3>
This is used in mathematics as well as other disciplines to explain the order by which values are arranged. This arrangement is usually done in such a way that the smallest value would come first and continue to climb till we get to the value that is the highest.
The values here have been arranged in this order in such a way that the smallest values came first while the bigger values are at the end.
