What is the amplitude, period, and phase shift of f(x) = −5 sin(x + 2π) − 4? 1. Amplitude = −5; period = π; phase shift: x = 2π

2. Amplitude = 5; period = 2π; phase shift: x = 2π 3. Amplitude = −5; period = π; phase shift: x = −2π 4. Amplitude = 5; period = 2π; phase shift: x = −2π

Answer:

  1. Amplitude is -5
  2. Period is 2π
  3. phase shift is -2π

Step-by-step explanation:

We can write a general wave function equation as:

f(x)=Asin(Bx+C))+D    

Where:

  • A is the amplitude .
  • 2π/B is the period
  • C  is the phase shift    
  • D is the vertical shift

Our equation is:

f(x) = -5sin(x+2\pi)-4  

Hence, comparing both equation we will conclude:

  1. Amplitude is -5
  2. Period is 2π
  3. phase shift is 2π

I hope it helps you!

Given that point A is the midpoint of line segment ED, where E( -1,9) and A(4,5), what is the location of point D?
yuradex [85]

Answer:

  D(9, 1)

Step-by-step explanation:

A being the midpoint means its coordinates satisfy ...

  A = (E + D)/2

Solving for D, we find ...

  D = 2A -E

  = 2(4, 5) -(-1, 9) = (2·4 +1, 2·5 -9)

  D = (9, 1)

KonstantinChe [14]

Answer:

A

Step-by-step explanation:

Here, we want to get the number that will be in the units place

Six consecutive numbers from 33 are;

33 , 34 , 35 , 36 , 37 , 38 ,

Product of 5 and any of the even numbers will yield 0

That means the number on the unit place is 0
