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}

To the nearest whole number, what is the surface area of a sphere with a volume of 140 cm³?
rjkz [21]

The answer to this question is B. 130cm^2.

Using the volume formula for a sphere (V = (4/3)πr^3) you can plug in the values that we know to find the radius to be around 3.22117 cm. You can then use the area of a sphere formula (A = 4πr^2) to find the area. Hope this helps :)
