Considering the relation {(elephant, 25), (reindeer, 32), (greyhound, 39), (elk, 45)}, we have that:
- The domain is: {elephant, reindeer, greyhound, elk}.
- The range is: {25, 32, 39, 45}.
<h3>What are the domain and the range of a function?</h3>
- The domain of a function is the set that contains all the values of the input.
- The range of a function is the set that contains all the values of the output.
In this problem, the relation is given as follows:
Hence, the relation is {(elephant, 25), (reindeer, 32), (greyhound, 39), (elk, 45)}, and the domain and range are given as follows:
- The domain is: {elephant, reindeer, greyhound, elk}.
- The range is: {25, 32, 39, 45}.

SAS Similarity postulate
Answer:
<em>The required values are a = 29°, b = 20°</em>
Step-by-step explanation:
<u>Angles and Lines</u>
The image shows two lines crossing at a point where three angles are marked: 57°, 7b-17, and 2a-1.
It can be noted that 57° and 7b-17 are linear angles whose sum is 180°:
57° + 7b - 17° = 180°
Solving for b:
7b = 180° + 17° - 57°
7b = 140°
b = 140°/7 = 20°
b = 20°
It can also be noted that 57° and 2a-1 are vertical angles (opposite angles). Vertical angles are congruent, thus:
57° = 2a - 1°
Adding 1:
2a = 58°
a = 29°
The required values are a = 29°, b = 20°
Answer:
x = 4.9
Step-by-step explanation:
We can use the intersecting chords formula:
(segment piece) x (segment piece) = (segment piece) x (segment piece)
7*7 = 10x
49 = 10x
Divide each side by 10
49/10=10x/10
4.9 = x
