There is a decrease in power. It can be concluded that there has also been a change in:
A) current or voltage.
I think the correct answer from the choices listed above is option A. A limitation of the kinetic-molecular theory for a gas is the <span>theory assumes that particles do not experience intermolecular forces.This cannot be completely true since interactions between particles is normal.</span>
Given:
The logarithmic expression is:
![\log_718](https://tex.z-dn.net/?f=%5Clog_718)
To find:
The equivalent expression of given expression by using change-of-base formula.
Solution:
The change-of-base formula is:
![\log_ba=\dfrac{\log_ca}{\log_cb}](https://tex.z-dn.net/?f=%5Clog_ba%3D%5Cdfrac%7B%5Clog_ca%7D%7B%5Clog_cb%7D)
The given expression is:
![\log_718](https://tex.z-dn.net/?f=%5Clog_718)
Using the change-of-base formula, we get
![\log_718=\dfrac{\log_c18}{\log_c7}](https://tex.z-dn.net/?f=%5Clog_718%3D%5Cdfrac%7B%5Clog_c18%7D%7B%5Clog_c7%7D)
Where, is a constant and c>0.
Let
, then
![\log_718=\dfrac{\log_{10}18}{\log_{10}7}](https://tex.z-dn.net/?f=%5Clog_718%3D%5Cdfrac%7B%5Clog_%7B10%7D18%7D%7B%5Clog_%7B10%7D7%7D)
Therefore, the correct option is a.
The standard form:
![Ax+By=C](https://tex.z-dn.net/?f=Ax%2BBy%3DC)
---------------------------------------
<em>use distributive property</em>
<em>multiply both sides by 8</em>
![8y-8=-2x+4\cdot3](https://tex.z-dn.net/?f=8y-8%3D-2x%2B4%5Ccdot3)
<em>add 2x to both sides</em>
<em>add 8 to both sides</em>
![\boxed{2x+8y=20}](https://tex.z-dn.net/?f=%5Cboxed%7B2x%2B8y%3D20%7D)
