Step-by-step explanation:
The function that we have to study in this problem is
The domain of a function is defined as the set of all the possible values of x that the function can take.
For a square-root function, there are some limitations to the possible value of the argument in the root.
In particular, the argument of a square root must be equal or greater than zero, because the square root of a negative number is not defined.
Therefore, in this case, we have to set the following condition for the domain:
And by solving, we get
which means that the domain of this function is all real numbers equal or greater than 5.
Answer:
<em>25 mg. is lighter than 25 cg.</em>
<em />
Step-by-step explanation:
<em>Well,</em>
<em />
<em>The prefix "milli" means thousandth and the prefix "centi" means hundredth. So a milligram will be one-tenth of a centigram.</em>
<em />
<em>10 mg. = 1 cg.</em>
<em>25 mg. = 2.5 cg.</em>
<em />
<em>2.5 cg. < 25 cg.</em>
<em />
<em>25 mg. is lighter than 25 cg.</em>
Answer:
Because the kind of compounfds that you try to determine using paper chromatography (organic compounds) are usually not soluble in water. Furthermore, water could react chemically with some of this compounds, because it's a very reactive molecule. You need organic solvents that are mostly inert.
