Answer:
Step-by-step explanation:
In order to identify the equation of line from the given graph, we need to find the slope and the y-intercept.
Slope of a line is the ratio of rise to run or change in over change in .
The y-intercept is a point on the line for which the value is 0. In other words, it is on the y-axis.
Here, from the graph,
y-intercept is at point (0,4). So, y-intercept is the value which is,.
Also, slope is given as,
Therefore, the equation of the line is:
3: Answer is 18 loaves
4: Answer is 8 loaves
5: Answer is 6 watermelons
6: Answer is 20 walls
The description of the corresponding partition is given as follows:
The infinite classes can be defined as:
At equal distance of x from point [1,2]
Where x can vary from o to infinity.
<h3>What is a corresponding partition?</h3>
The analogous partition, commonly known as "the set of equivalence classes," is the set A/R, the elements of which are the subsets of A satisfying the following:
For every a∈A there is some B∈A/R such that a∈B.

Answer:
9 pi
Step-by-step explanation:
First find the circumference of the circle
C =2 * pi *r
C = 2 * pi *9
C = 18 pi
This is a semicircle which is 1/2 of a circle
Take 1/2 of the circumference
1/2 C = 1/2 ( 18 pi)
1/2 C = 9 pi
