There are 2×2×2×2×2×2 = 2⁶ = 64 possible settings.
_____
Each switch can be in 2 positions, and for each of those, the other switches can have all possible settings. 1 switch has 2 settings. 2 switches will have 2×2 settings. 3 switches will have 2×2×2 settings.
It = 16x because 13 plus 3 is 16 so its 16x !!!
Explain how the reactions of “the bloodless ghouls” to Orpheus’s song in paragraph 3 are important to the overall theme of the story. Cite evidence from the story in your response.
(x-4)² + (x-2)² = x²
(x² - 8x + 16 ) + (x² - 4x + 4) = x
2x² -12x + 20 = x
2x²-12x + 20 - x = 0
2x² - 13x + 20 = 0
(2x-5) (x-4) = 0
2x-5 = 0
2x = 5
x = ⁵/₂
x-4 = 0
x = 4
so x₁ = ⁵/₂ , and x₂ = 4
Answer : b=3
Hope this helps have a great day! :)
