the volume of a gas varies inversely as the pressure upon it. if the volume of the gas is 160 cubic centimeters at a pressure of
marin [14]
It was stated in the problem that a given volume of a is inversely proportional with the pressure of the system. It means that the as the volume increases, the pressure would decrease and as the volume decreases, the pressure would increase. We would express it as:

V α 1/P

To change it to an equality, we introduce a proportionality constant, k. We do as follows:

V = k/P

So, to determine what is asked, we need to first calculate for the value of k.

V = k/P
At V = 160 m^3 P = 108 cmHg
160 = k / (108)
k = 17280

Thus, at P = 87 cmHg 
V = 17280 / 87 
V = 198.62 m^3

Find the distance between the two points.<br> (-6, – 7), (0,0)
Elden [556K]

Answer:

√85

Step-by-step explanation:

for this, you will probably need to draw a graph. Plot the points, and then you will notice that you can draw a triangle with one side being the x-axis ( go on to (-6,0) then drop down unitll you hit the point (-6;-7)

// use the pythagoream theorem to find the length

the distance of the leg on the x-axis is 6  (calculate 0-(-6))

the distance of the leg that is dropping down is -7 (calculate 0-(-7))

then we have 2 legs and need to find the hypotenuse.

Pythagorean theorem a^2 + b^2 = c^2

substitute :

6^2 + 7^2 = c^2

36+49 = 85

c= √85

Hunter-Best [27]
Bearing in mind that an absolute value expression is in effect a piece-wise function with two cases, thus

\bf |-n|=&#10;\begin{cases}&#10;+(-n)\\&#10;-(-n)&#10;\end{cases}\implies &#10;\begin{cases}&#10;-n\\&#10;n&#10;\end{cases}&#10;\\\\\\&#10;n|-n|=2n\implies &#10;\begin{cases}&#10;n-n=2n\implies 0=2n\implies &0=n\\&#10;n+n=2n\implies 2n=2n\impliedby &inconsistent&#10;\end{cases}
