Determine if a real life situation is a function or not
I will give 2 instances
(1) Students and their ID
The relationship is as follows:
Student 1 -----> ID-1
Student 2 -----> ID-2
Student 3 -----> ID-3
Student 4 -----> ID-4
---------
----
--
Student n -----> ID-n
The above is a function because every student has a unique student ID.
In fact, the relation is a one-on-one function because no two students will have the same ID
(2) People and their year of birth
The relationship is as follows:
Person 1 -----> 2000
Person 2 -----> 2001
Person 3 -----> 2002
Person 4 -----> 2001
---------
----
Person n -----> 2005
The above is not a function because there is a possibility that a more than one person will have the same year of birth.
we know that
The measure of the interior angle is the half sum of the arcs comprising it and its opposite
so
m∠CED=
see the attached figure with letters to better understand the problem
° ------> by central angle
° ------> by central angle
Substitute the values in the formula above
m∠CED=
m∠CED=
m∠CED=
°
therefore
<u>the answer is</u>
m∠CED=°

<u>Answer</u>:
There is enough fuel for the trip and the relative distance is 19 miles
<u>Explanation</u>:
Given Sedan drives
10 miles north
15 miles east
13 miles south
15 miles west
22 miles north
Then total distance = 10 + 15 + 13 + 15 + 22 = 75 miles
There are 5 gallons of gas left and sedan gets 20 miles per gallon
20 miles = 1 gallon
75 miles = 75/20 = 3.75 gallons
Gas left = 5 – 3.75 = 1.25 gallon
So, there is enough fuel for the trip
Relative distance = 10 (north) + 15 (east) – 13 (south) – 15 (west) + 22 (north) = 19 miles
