Using the function concept, a teacher's hobby cannot be represented as a function of the subject that teacher teaches, as <u>teachers of the same subject can have different hobbies</u>.
<h3>What is a function?</h3>
- In a function, <u>one value of the input can be related to only one value of the output.</u>
<u />
In this problem, the input is the teacher's subject, while the output is the hobby. As there can be teachers with the same subject but different hobbies, one value of the input would be mapped to multiple outputs, hence the situation cannot be represented by a function.

Answer: 48 square feet.
Step-by-step explanation:
So you can say 12x12 is 144. You know there are 4 sides. They will be all twelve as this is a square.
The perimiter is 12 plus 12 plus 12 plus 12 equals 48 square feet
Answer:
angle RUS = 65 degrees
angle STU = 90 degrees
Step-by-step explanation:
(a) find angle RUS
Given arc RU = 50 degrees, so angle RSU = 50/2 = 25 degrees
Since US is the diameter,
angle URS is a right-angle.
Consider triangle RUS,
sum of angles of a triangle = 25+90+RUS = 180
solve for
RUS = 180 - 25 - 90 = 65 degrees.
(b) Find STU
All diameters span a right angle at the circumference,
since we're given US is a diameter, this means that
angle STU is a right angle.
