On #29 x = 12 and <apb = 90° and <dcb = 40° and on #30 all I dont even understand, sorry
<span>At a 3% increase you would use 1.03 * 1000 L = 1030 L next year</span>
Answer:
Itd be 3 becaus 24/8 is 3
Using it's concept, it is found that the domain for the expressions is, respectively, given by:

<h3>What is the domain of a function?</h3>
It is the <u>set that contains all possible input values</u>.
In a fraction, the denominator cannot be zero, hence:
- The domain of the first two expressions is of
.
- The domain of the last expression is of
.
The third expression can be simplified, as:
(x + 5)/(x + 5) = 1.
The same is true for the fourth, as:
x²/x = 1.
Neither has any restriction, hence their domain is all real numbers, represented by
.
