Answer:
(-9, π/5 + (2n + 1)π)
Step-by-step explanation:
Adding any integer multiple of 2π to the direction argument will result in full-circle rotations, which are identities, so this family is equivalent to the give coordinates:
(9, π/5 + 2nπ), for any integer n
Also, multiplying the radius by -1 is a point reflection, equivalent to a half-turn rotation. Then add π to the direction for another half turn, and the result is another identity. So this too is equivalent to the given coordinates:
(-9, π/5 + (2n + 1)π), for any integer n
Answer:
5.5
Step-by-step explanation:
Answer:
One is 78 degrees and the other is 102 degrees
Step-by-step explanation:
In a linear pair the sum of the two angles will equal 180 degrees
x = One Angle
x+24= Other Angle
2x+24= 180
2x=156
x=78
x+24= 102
Check your work by adding the two and making sure it is equal to 180
102+78=180
3 3/4 =3.75
20.25 divide 3.75 = 5.4

Does the relation {(-2,2), (-7,1), (-3,9), (-8,4), (-9,5), (-6,8)) represent
Gelneren [198K]
Answer:
Yes
Step-by-step explanation:
This does represent a function because every x-value only goes to one y-value.
