Graphs are used to show relationships between related entities. See attachment for the graph that shows the relationship between the number of students and the number of buses.
Given that:


The given parameters can be represented as:

Where:
people
bus
When there is nobody (i.e. 0 people), then the number of bus will also be 0. So, we have:

To sketch the graph that represents the given relationship, we simply plot points (0,0) and (45,1) and connect both points

When dividing fractions the second term becomes the reciprocal
Answer:
12.56 square cm
Step-by-step explanation:
Let A be the area of the sector of circle.

Equation A simplifies to 0 = 0. It is always true.
Equation B simplifies to 1 = -1 for a ≠ 0. It is never true.
Equation C simplifies to 2a = 0. It is true only for a = 0.
Equation D simplifies to 2a = 0. It is only true for a = 0.
The equation that is true for all values of "a" is ...
A. Equation A
