Answer: The bubbles will shrink , some may vanish.
Explanation:
The bubbles will shrink, and some may vanish observed during the experiment.
Why bubbles are formed in carbonated water?The bubbles are made from a gas called carbon dioxide. The soda company puts the carbon dioxide in the soda to give it that special fizz. You can see some of this , bubble, in this activity with soda water.
The bubbles are formed because the carbonic acid of the soft drink decomposes and forms carbon dioxide gas, which has low solubility in liquids. The decomposition reaction is a reversible reaction:
H₂CO₃(l) ⇄ CO₂(g) + H₂O
When the bottle is shaken, the molecules of the drink became more agitated, so the pressure of it will increase. The increase of pressure in a reversible reaction shifts the equilibrium of the formation of the less gas molecules. So, the CO₂ will dissolve in liquid, and less bubbles will be seen.

17.2 defining and evaluating the basic trigonometric functions answer key
An example of basic trigonometric functions question is find tan [tex]\frac{11\pi }{4}[/tex].
What are trigonometric functions?The term trigonometric function is known to be made up of functions such as sine (sin), cosine (cos), tangent (tan), etc., that stands for the ratios of sides of all right triangles.
To solve for tan [tex]\frac{11\pi }{4}[/tex]
It will be [tex]\frac{11\pi }{4}[/tex] = 2[tex]\pi[/tex] + [tex]\frac{3\pi }{4}[/tex]
θ = [tex]\pi -\frac{3}{4} \pi[/tex]
θ = [tex]\frac{\pi }{4}[/tex]
To know the right angle,
θ = [tex]\frac{\pi }{4}[/tex] x 180/4 = 45⁰
tan θ = 1
Therefore, tan [tex]\frac{11\pi }{4}[/tex] = -1

Which equation describes the relation indicated by the table
Answer:
Answer: - (1/2)x + 2
Explanation: 1) Table
x y
-2 3
0 2
4 0
6 -1
The first thing that you must probe is whether the relation is linear.
When the relation is linear the rate of change is constant.
The rate of change is Δy / Δx
2) Let's calculate that rate for all the points given:
x y
-2 3
0 2 ---> Δx = 0 -(-2) = 2, Δy = 2 - 3 = - 1 => Δy / Δx = - 1/2
4 0 ---> Δx = 4 - 0 =4, Δy = 0 - 2 = -2 => Δy / Δx = -2/4 = - 1/2
6 -1 ---> Δx = 6 - 4 = 2, Δy = - 1 - 0 = -1 => Δy / Δx = - 1/2
So, we have shown that the relation is linear.
3) Now, you can use the equation of the line: y = mx + b, where m is the slope (rate of change Δy / Δx) and b is the y-intercept.
We already found m = -1/2
The y-intercept is the value of y when x = 0, which you can get from the table; b = 2.
Therefore the equation is: y = (-1/2)x + 2.
