The balloon will be collapsed due to the excess pressure.
what happened?if we press on a balloon that is already filled by air stretched over the jar, the air of the jar will enter the balloon and create excess pressure beyond its tolerance and finally the balloon will be collapsed.
what we understand by the result?as the air-filled balloon is pressed directly over a jar, there is no way to leakage of air, besides the air of jar enter the balloon causes high pressure on the wall of balloon and finally it is destroyed.

12. How could you write a system of inequalities using the quadratic functions in
the graph so that (6, 6) is a solution to the system but (6, -6) is not a solution to
the system.
Answer:
To write a system of inequalities that has the point (6, 6) as a solution but not (6, -6), we can use the fact that the point (6, 6) is above the graph of the quadratic function, but the point (6, -6) is below the graph. Therefore, we can write a system of inequalities that includes the condition that the y-value must be greater than the value of the quadratic function at a given x-value.
For example, we could use the quadratic function y = x^2 and write the following system of inequalities:
y > x^2
y > 6
The first inequality states that the y-value must be greater than the value of the quadratic function at a given x-value. The second inequality is added to ensure that the y-value is greater than 6, which is necessary for the point (6, 6) to be a solution.
Since the point (6, 6) satisfies both of these inequalities, it is a solution to the system. However, the point (6, -6) does not satisfy the first inequality, since the y-value is less than the value of the quadratic function at x = 6. Therefore, it is not a solution to the system.
Overall, the system of inequalities would be as follows:
y > x^2
y > 6

How do you graph a rational function example?
To graph a rational function example, start by writing the equation in the form y = (ax + b)/(cx + d).
Then, plot the points where the denominator equals zero (when x = -d/c). These points are called vertical asymptotes.Next, plot the points where the numerator equals zero (when x = -b/a). These are called horizontal asymptotes.Finally, plot points between the vertical and horizontal asymptotes to graph the rational function.Plotting the points between the vertical and horizontal asymptotes will allow you to see the shape of the graph. Start by plotting points on either side of the vertical and horizontal asymptotes. Then, plot points at evenly spaced x-values between the vertical and horizontal asymptotes. For example, if the vertical asymptote is at x=-d/c, and the horizontal asymptote is at x=-b/a, you can plot points at x=-1.5d/c, x=-0.5d/c, x=-1.5b/a, and x=-0.5b/a. By plotting these points and connecting them with a smooth curve, you can graph the rational function.

What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).
As per the given table,
The function f(x) = -7x + 22 is satisfying the table.
For example at x = 2
f(2) = -7 x 2 + 22 = 8
Now, since, g(x) = f(x) + 5 thus g(x) is translated up to 5 units.
Hence "The formula f(x) = -7x + 22 and the translation of f(x) up 5 is g(x).".

If the scale of drawing is 1 inches : 250 inche and the real horse height is 15 inche, then the height of the horse in drawing is 0.06 inches.
What does a scale look like in math?The ratio that describes the relationship between the true figure itself and model is called the scale. It serves as a representation of the real statistics in smaller units on maps. A scale of 1:5, for instance, indicates that 1 on the map is approximately the size of 5 in the actual world.
Briefing:The scale of drawing the horse = 1 inch :
Therefore in scale
Horse height in drawing equals one inch
The height of the horse = 250 inche
The original height of the horse = 15 inche
The height in the picture = x inches
To find the height the horse in the picture, we have to use proportion
1 inch : 250 inche = x inches : 15 inche
1 / 250 = x / 15
1 × 15= 250x

A company finds that its advertising costs increased from 72000 to 76680 in a year. What was the rate of increase?
Using the percentage increase formula, we know that the rate of increase in the advertising cost of the company is 93.5%.
What is the percentage?In mathematics, a percentage is a number or ratio that is expressed as a fraction of 100.
The percent symbol, "%," is widely used to denote it even if the abbreviations "pct," "pct," and rarely "pc" are also employed.
A% is a number that has neither dimensions nor a defined unit of measurement.
For instance, if you properly answered 75 out of 100 questions on a test, you would have received a 75% grade (75/100).
So, the percentage increase formula:
% increase: original - increase/original * 100
Increase: 76680-72000 - 4680
Now, substitute values as follows:
% increase: original - increase/original * 100
% increase: 72000 - 4680/ 72000* 100
% increase:93.5
Therefore, using the percentage increase formula, we know that the rate of increase in the advertising cost of the company is 93.5%.
