Answer:
.75 g
Step-by-step explanation:
If you have 15 g and 5% is boric then 15 *.05 =.75
Given that
and
, we can say the following:

Now, remember what happens if we have a negative square root: it becomes an imaginary number. We don't want this, so we want to make sure whatever is under a square root is greater than 0 (given we are talking about real numbers only).
Thus, let's set what is under both square roots to be greater than 0:


Since both of the square roots are in the same function, we want to take the union of the domains of the individual square roots to find the domain of the overall function.

Now, let's look back at the function entirely, which is:

Since
is on the bottom of the fraction, we must say that
, since the denominator can't equal 0. Thus, we must exclude
from the domain.
Thus, our answer is Choice C, or
.

Answer:
4/10 is equivalent to 2/5
Step-by-step explanation:
because 4/10 is written as 0.4 in decimal form and so is 2/5, which means they are equivalent
