Answer:
D.
Step-by-step explanation:
In direct variations, we would have:
Where <em>k</em> is some constant.
Since this is indirect variation, instead of that, we would have:
To determine the equation, find <em>k</em> by putting in the values for <em>q </em>and <em>r:</em>
<em /><em />
Now plug this back into the variation:
The answer is D.
The equation that is equivalent to the considered equation of log is given by: Option E: 2^3 = x+5
<h3>What is logarithm and some of its useful properties?</h3>When you raise a number with an exponent, there comes a result.
Lets say you get
Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows
'a' is called base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'
Some properties of logarithm are:
Log with base e = 2.71828... is written as simply.
Log with base 10 is written as simply.
The equation given is:
By using the definition of log, which says , we get:
or
Thus, the equation that is equivalent to the considered equation of log is given by: Option E:
(we used the fact that the question is asked in a way that expresses that there is only one equivalent equation. Plus we used the fact that as option E is a sure equivalent version, so it is correct option).
Thus, the equation that is equivalent to the considered equation of log is given by: Option E:
