<h3>
Answer:</h3>
Any x value that makes the denominator equal to 0
<h3>
Explanation:</h3>
Rational Functions
The quotient of two functions can be rewritten as a rational function. All rational functions have discontinuities in the domain where the denominator equals 0. For this to make sense, remember that anything divided by 0 is undefined.
Examples
To show this idea, I will use the example . For this rational function or quotient of two functions, the x value -3 is not included in the domain. This is due to the fact that when x=-3, the denominator is equal to 0. Thus, the function is undefined at this value.
D. salt and water do not produce a chemical reaction, rather a physical one, thats why the salt stays behind after the water disappears... because it never changed other than its physical appearance
Taking into account the definition of molarity, the concentration of CH₃OH in the solution is 3.12 .
<h3>Definition of molarity</h3>
Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:
Molarity is expressed in units .
<h3>Concentration of CH₃OH</h3>
In this case, you know:
- number of moles= 50 g× = 1.56 moles, being 32.04 the molar mass of CH₃OH
- volume= 500 mL= 0.5 L (being 1000 mL= 1 L)
Replacing in the definition of molarity:
Solving:
<u><em>Molarity= 3.12 </em></u>
Finally, the concentration of CH₃OH in the solution is 3.12 .

:( im in XI grade so
Explanation:
Answer: Lower CI=21-t(0.025, 16)*7/sqrt(17)=21-2.12*7/sqrt(17)=17.4
upper CI=21+t(0.025, 16)*7/sqrt(17)=21+2.12*7/sqrt(17)=24.6
Explanation: Because there both close and equal
