When there are two factors—a fixed element and a variable factor—the law of variable proportions is created. According to the law of variable proportions, the marginal product of a factor will gradually decrease when its quantity is raised while the other elements remain constant.

We are aware that the relationship between the number of units of a variable factor and the entire physical product is shown by the law of variable proportions.

Additionally, the TPP increases initially at a rising pace, then at a falling rate, and finally declines if we maintain other parameters constant and increase the units of the variable factor.

According to the law of variable proportions, if a producer raises the units of a variable factor while keeping other elements constant, the total product will initially increase at an increasing pace, then it will increase at a diminishing rate, and finally it will begin to decline.

Point G is two, which divides the directed line segment from D to F into a 5:4 ratio at that place.

The general equation for every straight line is y = mx + c, where m is the gradient (or degree of steepness) of the line and c is the y-intercept (the point in which the line crosses the y-axis).

The variables x and y are related to coordinates on the line in the linear equation y = mx + c.

The formula y = mx + c yields a result for y when we enter a value for x.

As y depends on the value of x, it follows that x is an independent variable and y is a dependent variable.

According to our question-

From negative five to positive ten is a number line.

Points D and F are at -2 and +7, respectively.

The area of the triangle having sides 3 cm 4 cm and 5 cm is calculated to be 6 cm².

Given that,

The sides of the triangle are said to be 3 cm, 4 cm and 5 cm.

By looking at the lengths of the sides of the triangle, it is clear that they are the sides of a right angled triangle. The Pythagorean theorem can be used to verify this.

5² = 3² + 4²

25 = 25

So, 5 is said to be the hypotenuse side of the right triangle and 3, 4 are said to be the base and height of the right triangle.

The formula to find out the area of the triangle is given by,

Area A = 1/2 × Base b × Height h

A = 1/2 × b × h

From the above conclusion, b and h are found to be 3, 4.

So, A = 1/2 × b × h = 1/2 × 3 × 4 = 6 cm²

The original linear function is:

y = 2*x + 4   with the point (1, 6)

The translated function is:

y = 2x + 7

And the translated point is (-3, 1)

First, we want to write a random linear function, I will use:

y = 2*x + 4

To find a point on that line, we can just evaluate the function in x = 1, we will get:

y = 2*1 + 4

y = 2 + 4

y = 6

So we have the point (1, 6)

Now we want to translate it 4 units to the left and 5 units down.

To translate it 4 units to the left, we need to add 4 to the argument.

y = 2*(x + 4) + 4

And to translate it  5 units down, we just need to subtract 5, we will get:

y = 2*(x + 4) + 4 - 5

Now we can simplify this to get:

y = 2*x + 2*4 + 4 - 5

y = 2x + 8 + 4 - 5

y = 2x + 7

The new coordinates of the point are the same as the last ones, but we subtract 4 to the x-value and 5 to the y-value:

We know 2 angles, one is 63 degrees and one is 86 degrees.

63 + 86 = 149 degree

180 - 149 = 31 degree

So, the angle of the triangle is 31 degrees. Now we know that angle add with the x to get 180 degrees, so

180 - 31 = 149 degree

So, x = 149 degree

After using the triangle inequality theorem, the possible values of the unknown side of the triangle is 15 < n < 25.

In this case, we are given that:

The lengths of the sides of a triangle are 20, 5, and n centimeters.

The theorem of triangle inequality stated that the lengths of any two of a triangle's sides added together must be bigger than the length of the third side. Given two sides, x and y, we can use the triangle inequality theorem to predict that the length of the third side will be between x + y and x - y.

Therefore,

x - y < n < x + y

20 - 5 < n < 20 + 5

15 < n < 25

As the result, the possible value of the unknow side of the triangle would be 15 < n < 25.

For all samples of 5, there is a 0.05 probability that the sample mean would be higher than 22 pounds.

The selection of bags weights, on average, 19.7 pounds.

The standard variation is 3.1 pounds.

Both the normal probability density function and the sampling distribution theorem were used.

When dealing with issues involving samples of data that are regularly distributed, the z-score algorithm is applied.

The z-score of a measure X is calculated as follows:

z = (x - μ) ÷ σ

The number of standard deviations is calculated using the Z-score. The average is the metric employed.

We examine the p-value linked with the Z-score in the z-score table after computing the Z-score.

The chance that the measure's value is less than X, or what proportion of X, is represented by this p-value.

We may calculate the likelihood that the metric exceeds X by subtracting 1.

The Central Limitation Theorem also holds for skewed variables when n is at least 30.

The sample mean will remain constant regardless of sample size.

The standard error, though, will alter.

The probability that the sample means will be higher than 22 is shown by P(a > 22).

For all samples of size 5, the possibility that they will weigh more than 22 pounds is about 0.05.

The system of equations is:

-2 = a + b + c

7 = 4a - 2b +c

-2 = 25a + 5b + c

The polynomial is:

y = (1/3)*x^2 - 6x - 1/3

The general polynomial of degree 2 can be written as:

y = a*x^2 + b*x +c

If we use the fact that it passes through the 3 given points, then we can write the 3 equations:

-2 = a*1^2+ b*1 + c

7 = a*(-2)^2 + b*-2 + c

-2 = a*5^2 + b*5 + c

We can simplify these to get the system of equations:

-2 = a + b + c

7 = 4a - 2b +c

-2 = 25a + 5b + c

First, isolate c on the first equation to get:

c = -2 - a- b

Replace it on the other two:

7 = 4a - 2b + (-2 - a - b)

-2 = 25a + 5b + (-2 - a - b)

9 = 3a - 3b

0 = 24a + 4b

Using the second equation we can rewrite:

-24a = 4b

-24a/4 = b

-6a = b

Ande replace that in the other equation:

9 = 3a - 3*(-6a)

9 = 3a + 18a

9/21 = a

1/3 = a

And the value of b is:

-6*(1/3) = b

-2 = b

And the value of c is:

the volume of the rectangular prism is 1/2 x³.

What is rectangular prism?

The normal's length from the prism's base to its top base serves as a gauge for the structure's height. At their base, certain prisms have an angle. Prism's top end is referred to as the "base" since the word "base" can refer to either end of a prism. The area (A) of the base of a prism's base times its height (H) equals the prism's volume (V). Since A is the base area and H is the prism's height, the volume of the prism is therefore A H cubic units.

The base area is A = x*x =x²

The height is 1/2 x

The volume of the rectangular prism is A*H = 1/2 x³.

A line that is perpendicular to another line has a slope that is the negative reciprocal of the original line. The slope of the line y = 2/7x - 8 is 2/7. To find the slope of the line that is perpendicular to it, we take the negative reciprocal of 2/7 which is -7/2.

We know that the line we're trying to find passes through the point (-4, 2), so we can use this point and the slope to write the equation of the line in point-slope form:

y - y1 = m (x - x1)

where (x1, y1) is the point the line passes through, m is the slope, and y and x are the coordinates of any point on the line.

So the equation of the line that passes through (-4,2) and is perpendicular to the line y= 2/7x - 8 is:

y - 2 = -7/2 (x + 4)

Simplifying this, we get

y = -7/2 x - 8

Therefore the equation of the line that passes through (-4,2) and is perpendicular to the line y= 2/7x - 8 is y = -7/2 x - 8
