We know that
[length of a circle]=2*pi*r
r=12 in
[length of a circle]=2*pi*12--------------> 24pi in
if 360° (full circle)--------------------> has a length of 24pi in
X-------------------------------------------> 8pi
X=8pi*360/24pi-----------> 120°
the answer is 120°
Answer:
y=1.5x
b is the y intercept but it is 0 so no need to add it. y is the result
An ordered pair of the function is (x, y).
Function:
In math, a set of ordered pairs in which each x-element has Only One y-element associated with it is known as function.
Given,
Here we need to define the ordered pair of the function.
In order to find the order pair of the function, first we have to know the definition of ordered pair,
In math, ordered pair contains the coordinates of one point in the coordinate system.
Where a point is named by its ordered pair of the form of (x, y).
Here the first number corresponds to the x-coordinate and the second to the y-coordinate.

Answer:
(1) is a function, surjective aka onto,
not bijective aka one to one.
domain is {3,6,12,14,20,22},
range is {4,15,8,11}. More elements in domain means it can't possibly be one to one.
(2) is a relation but not a function, although its inverse is a function. There are fewer elements in the domain than the range, so a function could not be onto but would have to be into or injective.
The relation you get by restricting the domain to {1,19} is a function, injective, so that the image of the domain is a proper subset of the range.
If we reflect about a line that is parallel to the x-axis, then the x-coordinate of the point (that is reflected) will remain the same, thus the image of (2,-4) has x-coordinate 2 and thus the point is of the form (2,b).
