<h3><u>Explanation</u></h3>
A function is a set of relation without repetitive domain. That means we cannot have the same value of x in a set.
<u>Example</u>
{(1,1),(1,2),(2,4),(3,9)}
This is not a function because the relation has same two x = 1 which does not make it a function.
{(1,1),(2,4),(3,9)}
This is a function because there are no same x-values or repetitive domain in a single set.
Back to the question, we can find which table represent a function by looking at the x-value table. If there are two same or more x-values, it is not a function.
<h3>
<u>Answer</u></h3>
The answer is the left bottom table as the other table have two same x-values.
Answer:
Step-by-step explanation:
The relevant relations here are ...
- the sum of arc measures in a semicircle is 180°
- the sum of angles in a triangle is 180°
<h3>Arc measures</h3>
The given arc CD is part of the semicircular arc CDA. The remaining arc, DA, is the supplement of CD:
arc DA = 180° -CD = 180° -125° = 55°
Central angle AOD has the same measure, 55°. That is one of the acute angles in right triangle AOB, so the other one is the complement of 55°.
∠ABO = 90° -∠AOB = 90° -55°
∠ABO = 35°
<h3>Triangle angles</h3>
In right triangle ABC, angle ABC is given as 55°. The other acute angle, ACB, will be the complement of this.
∠ACB = 90° -∠ABC = 90° -55°
∠ACB = 35°
In the figure, angles ABO and ACB have measures of 35°.
Answer:
-56
