Question asked: if a number has an absolute value equal to 9,that number could be ____?

My answer: it would be C. -9 or 9

The answer is C. -9 or 9.

The absolute value of a number is just that number's positive form, so we know the answer won't be D.

A and B are both correct, but it's not just those one numbers. The only answer correct is C, because it shows all correct answers, not some of the right answers.

Half doing work is the same as not doing it.

Answer: A = 4    P = π     PS = -π/2

<u>Step-by-step explanation:</u>

y = A sin(Bx - C) + D      where

  • A is the amplitude
  • Period = 2π/B
  • Phase Shift = C/B
  • D is the vertical shift

Given:  y = -4 sin(2x + π) - 3

  • A (amplitude) = 4      <em>the negative sign is a reflection, not amplitude</em>
  • B = 2
  • C = -π
  • D = -3

Amplitude = 4

\text{Period}=\dfrac{2\pi}{B}\quad =\quad \dfrac{2\pi}{2}\quad =\quad \pi

\text{Phase Shift}=\dfrac{C}{B}\quad =\quad \dfrac{-\pi}{2}\quad =\quad -\dfrac{\pi}{2}
