Answer:
17 cm
Step-by-step explanation:
1. Depth in fresh water
p(water) = hρg
d(max) = h = p/(ρg)
Convert atmospheres to pascals
0.056 atm × 101 325 Pa/1 atm = 5670 Pa
h = 5670 Pa/(1000 kg·m⁻³ × 9.806 m·s⁻²) × (1 kg·m⁻¹s⁻²/1 N) = 0.579 m
2. Depth in Dead Sea
d(max) = 5670/(1400 × 9.806) = 0.413 m
3. Difference
Difference = 0.579 – 0.413 = 0.17 m = 17 cm
The difference in d(max) is 17 cm.

Answer:
We start with the equation:
(x^2 - 1)/(x + 1) = 2
We want to rewrite this in standard form.
We can multiply both sides by (x + 1) to get:
((x^2 - 1)/(x + 1))*(x + 1) = 2*(x + 1)
x^2 - 1 = 2*(x + 1) = 2*x + 2
Now we can move all the terms to one side to get:
x^2 - 1 - 2 - 2*x = 0
x^2 - 2*x - 3 = 0
And this is a standard quadratic equation, that we can solve by using the Bhaskara's formula, this will give us the solutions:
![x = \frac{-(-2) \pm \sqrt{(-2)^2 - 4*1*(-3)} }{2*1} = \frac{2 \pm 4}{2}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B-%28-2%29%20%5Cpm%20%5Csqrt%7B%28-2%29%5E2%20-%204%2A1%2A%28-3%29%7D%20%7D%7B2%2A1%7D%20%20%3D%20%5Cfrac%7B2%20%5Cpm%204%7D%7B2%7D)
Then the two solutions are:
x = (2 + 4)/2 = 3
x = (2 - 4)/2 = -1
Answer:
<em>Mode</em>
Step-by-step explanation:
A central tendency measure (also referred to as center or central place measure) <em>
is a descriptive measure that tries to define a whole collection of information with a single variable representing its distribution center or middle.
</em>
There are three primary key trend measurements: mode, median and the mean.
The mode <em>is a distribution's most common value.</em>
The diver's depth is indicated by a value of -5.875 feet before he or she swims to the surface. This is further explained below.
<h3>What is a diver?</h3>
Generally, A person who can breathe underwater for extended periods of time without returning to the surface, any of several species of birds that feed mostly by diving into bodies of water.
In conclusion, It has been shown that a diver must swim upwards of 5.875 feet in order to reach the water's surface. The diver is rising because they are approaching the surface of the water. Since the diver began his journey below the water's surface, his elevation was negative until he reached the surface.
For this reason, a number of -5.875 feet is used to represent the diver's depth just before surfacing.
