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:C
Step-by-step explanation:In a box plot the median is the line that lines with the number that on the box plot. So the line is between 8 and 9 but to find the number that is between 8 and 9,first add 9+8=17 then divide 17 with 2 which is 17÷2=8.5.Therfore the numbers that are between 8 and 9 is 8.5.
Use FOIL (First, Outside, Inside, Last)
x(x) = x²
x(9) = 9x
-2(x) = -2x
-2(9) = -18
x² + 9x - 2x - 18
simplify by combining like terms
x² + 9x - 2x - 18
x² + 7x - 18
x² + 7x - 18 is your answer
hope this helps
