The large hose fills 1 pool in 9 hours written as 1/9
The small hose fills 1 pool in 18 hours, written as 1/18
Now you have 1/9 + 1/18 = 1/x ( x is the unknown time for both hoses).
rewrite 1/9 with a common denominator as 1/18:
1/9 = 2/18
Now you have 2/18 + 1/18 = 1/x
Add the left side:
2/18 + 1/18 = 3/18
Now you have 3/18 = 1/x
Cross Multiply:
3x = 18
Divide both sides by 3"
x = 18/3
X = 6
It will take both hoses 6 hours.

Step-by-step explanation:
The domain and range of the graph of a logarithmic function are;
- Range; The set of real numbers.
<h3>How can the graph that correctly represents a logarithmic function be selected?</h3>
The basic equation of a logarithmic function can be presented in the form;

Where;
b > 0, and b ≠ 1, given that we have;


The inverse of the logarithmic function is the exponential function presented as follows;

Given that <em>b</em> > 0, we have;

Therefore, the graph of a logarithmic function has only positive x-values
The graph of a logarithmic function is one with a domain and range defined as follows;
Domain; 0 < x < +∞
Range; -∞ < y < +∞, which is the set of real numbers.
The correct option therefore has a domain as <em>x </em>> 0 and range as the set of all real numbers.
