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}

Which are steps that could be used to solve 0 = 9(x2 + 6x) – 18 by completing the square? Check all that apply.
jeyben [28]
18 + 81 = 9(x²<span> + 6x + 9)
</span><span>11 = (x + 3)</span>²

When we are completing the square, we are going to move the value of c across the equals.  We will do that by adding, and end up with

18=9(x²+6x)

We take the value of b (the coefficient of x), divide it by 2 and square it:
(6/2)²=3²=9

This is the value that completes the square.  However, since the entire square is multiplied by 9, this value must be multiplied by 9 before we can add it across the equals:
18+9(9) = 9(x²+6x+9)
18+81=9(x²+6x+9)
99=9(x²+6x+9)

Dividing both sides by 9, we have:
11=x²+6x+9

11=(x+3)²

Roster Method.........
Natalija [7]

Answer:

The roster method is defined as a way to show the elements of a set by listing the elements inside of brackets. An example of the roster method is to write the set of numbers from 1 to 10 as {1,2,3,4,5,6,7,8,9 and 10}. An example of the roster method is to write the seasons as {summer, fall, winter and spring}.Step-by-step explanation:

Answer:

\sf\longmapsto \: x = 10

Step-by-step explanation:

Subtract 7 from both sides:

7−5x−7=−43−7

Simplify:

−5x=−50

Divide both sides by −5:

\sf\longmapsto \:  \frac{ - 5x}{ - 5}  =  \frac{ - 50}{5}

\sf\longmapsto \: x = 10
