-253 IS deeper than -280 in water. As your going into the negatives, The smaller numbers are bigger than the big numbers. It is the opposite when it comes to positive numbers.
The volume of a sphere uses the following formula:

Because the question asks to use 3.14 in place of pi, the formula will now look like this:

We are given a diameter of 118 feet. The radius is half of the diameter, so divide the diameter by 2 to find the radius:


Plug this value into the formula, and solve with a calculator:

Although our result is one cubic foot off, the answer is
<span>
A. 859,852ft^3.
(859,852 is the result if the constant in the given formula is 4.18666, but the result with infinitely repeating numbers is 859,853.)</span>
To solve this problem, we need to use the midpoint formula, where M = (x1+x2/2, y1+y2/2). To solve, we must plug in the given (x,y) values from our ordered pairs and then simplify, shown below:
(x1+x2/2, y1+y2/2)
( (16 + -6)/2, (5 + -9)/2 )
Now, we can begin to simplify by computing the addition in the numerators of both fractions.
(10/2, -4/2)
Next, we can finish the simplification process by dividing these fractions.
(5, -2)
Therefore, the midpoint of (16,5) and (-6,-9) is (5,-2).
Hope this helps!
First we expand and combine the terms on the left side. This gives us
12x + 32 -4x + 8 = -8x + 40
8x + 40 = -8x + 40. Because the two sides cancel each other out when you try and bring all the x to one side, the answer is x = 0.
Answer:




Solving for
we got
and replacing this we got:



And then the best option for this case would be:
b.csc x
Step-by-step explanation:
For this case we have the following expression given:

We know from math properties that the definition for cot is 
If we use this definition we got:


Now we can use the following identity:

Solving for
we got
and replacing this we got:



And then the best option for this case would be:
b.csc x
