X1=(-16√16^2-4*1*9)/(2*1) = (-16 - 2*√55)/ 2=-15.416
X2=(-16+√16^2-4*1*9)/(2*1) = (-16+2*√55)/2=-0.584
Answer:
- Amplitude is -5
- Period is 2π
- phase shift is -2π
Step-by-step explanation:
We can write a general wave function equation as:
Where:
- A is the amplitude .
- 2π/B is the period
- C is the phase shift
- D is the vertical shift
Our equation is:
Hence, comparing both equation we will conclude:
- Amplitude is -5
- Period is 2π
- phase shift is 2π
I hope it helps you!
.25 is one quarter in words
Length is 1,406.25 because area is all sides multiplied and 5,625 divided by 4 (because it’s a square) is 1,406.25
And to check do 1,406.25 times 4
Answer:
![y=-2x+9](https://tex.z-dn.net/?f=y%3D-2x%2B9)
Step-by-step explanation:
y = mx + b
The slope (m) is negative since the line is pointing downwards.
The slope is equal to rise over run. The points go down 2 over 1, which is 2/1 or 2.
B, aka the y-intercept, is equal to 9
