How to tell if its identifying functions is <br> a function or not
Svetach [21]

Answer:

Step-by-step explanation:

Determining whether a relation is a function on a graph is relatively easy by using the vertical line test. If a vertical line crosses the relation on the graph only once in all locations, the relation is a function. However, if a vertical line crosses the relation more than once, the relation is not a function.

Arc length is the angle/360 times circumference. The diameter of the unit circle is 2. So the circumference of the unit circle is 2pi, if you use 3.14 for pi, then the circumference is 6.28. So your equation is
x/360 times 6.28=4.2, divide by 6.28, then multiply by 360
x=240.76432
Your answer rounded to the nearest thousanth is 240.764

Quadrilateral ABCD has the following vertices.
Marizza181 [45]
A(-5,5)
B(4,5)
C(2,0)
D(-5,-2)

AB,BC,CD,DA

AB = [4-(-5)),5-5]=[9,0]
Lenght  AB= \sqrt{9^2+0^2}= \sqrt{81}  =9

BC = [2-4,0-5]=[-2,-5]
Lenght  BC=\sqrt{(-2)^2+(-5)^2}=\sqrt{4+25}=\sqrt{29}

CD = [-5-2,-2-0]=[-7,-2]
Lenght  CD=\sqrt{(-7)^2+(-2)^2}=\sqrt{49+4}=\sqrt{53}

DA =[-5-(-5),-2-5]=[0,-7]
Lenght DA=\sqrt{0^2+(-7)^2}=\sqrt{49}=7

sorted from longest to shortest:
AB, CD,DA,BC
\sqrt{81}, \sqrt{53}, \sqrt{49}, \sqrt{29}
