Answer:

A= 1, B= 2, C= 3 D= 2

Step-by-step explanation:

A fundamental identity is an equation that relates the values of the trigonometric functions for a given angle. The equation cot θ = cos θ/sinθ is an example of a fundamental identity.

This identity states that the cotangent of an angle is equal to the cosine of the angle divided by the sine of the angle. The equation sec θ = 1/cosθ is another example of a fundamental identity. This identity states that the secant of an angle is equal to the reciprocal of the cosine of the angle. The equation sec^2 + 1 = tan^2θ is also a fundamental identity. This identity states that the square of the secant of an angle plus one is equal to the square of the tangent of the angle. The equation 1 + cot^2θ = csc^2θ is not a fundamental identity. This equation states that one plus the square of the cotangent of an angle is equal to the square of the cosecant of the angle. This equation is not a fundamental identity because it does not relate the values of the trigonometric functions for a given angle.

Answer= 6 and 7/y6 this will be the correct answer

The first block's acceleration is inversely proportional to its mass and directly proportional to the mass difference between the two blocks.

Without being aware of the precise values of m1, m2, and g, it is impossible to calculate the acceleration of the first block.

Newton's second rule of motion, which states that the net force on an object is equal to its mass times its acceleration, can be used to calculate the acceleration of the first block in the illustration.

Let's call the first block's acceleration "a." The difference between the tension force in the rope connecting the two blocks and the force of gravity can be used to calculate the net force exerted on the first block.

The rope's tension force is generated by:

T = m2 × g

The first block is subject to the following gravitational force:

Fg = m1 × g

The difference between these two forces is the net force exerted on the first block:

Fnet = T - Fg = (m2 - m1) × g = m2 × g - m1 × g

In light of Newton's second law, we can say:

Fnet = a × m1

(m2 - m1) × g = m1 × a

When calculating acceleration, we obtain:

a = (m2 - m1) × g / m1

As a result, the first block's acceleration is inversely proportional to its mass and directly proportional to the mass difference between the two blocks.

Step-by-step explanation:

6x + 10y = 10   You add the two equations together

-6x - 24 y = 18

       -14y = 28   Divide both sides by -14

y = -2

Substitute -2 for y into either of the two equations above or the two original equations.  I am going to choice

3x + 5y = 5

3x  + 5(-2) = 5

3x -10 = 5  Add 10 to both sides

3x - 10 + 10 = 5 + 10

3x = 15  Divide both sides by 3

x = 5

Check:

3x + 5y = 5

3(5) + 5(-2) = 5

15 - 10 = 5

5 = 5  Checks

-2x - 8y = 6

-2(5) - 8(-2) = 6

-10 + 16 = 6

The given question is not complete, similar kind of question is attached below.

In statistics the sampling method is collecting data based on sample of people who represent a population, whereas the census method involves studying each and every member of the population.

What is statistics?

The gathering, characterization, analysis, and drawing of inferences from quantitative data are all tasks that fall under the purview of statistics, a subfield of applied mathematics. Probability theory, linear algebra, and differential and integral calculus play major roles in the mathematical theories underlying statistics.

The differences between census and sampling method is -

The investigator gathers data using the census method, which asks questions about every component of the population.

The investigator gathers data using the sampling method by selecting a sample of the objects that represent the entire population.

The Census Method of Collecting Data is appropriate when the area under inquiry is rather small. The sampling method is preferred when the investigation region is large.

The Census Method requires more time to gather data. The sampling method requires less time to gather data.

Generally speaking, the Census Method is more accurate than the Sampling Method. This accuracy can be attributed to the Census Method's inclusion of a study of every component of the population. The sampling approach has a lower level of accuracy because it examines a smaller sample of the population. However, since there are fewer elements in the sampling method, errors are simple to find and eliminate. Consequently, if that's the case, the sampling method gives more accuracy than census method.

Therefore, the differences for census and sampling method are pointed out.

The answer is the median would not change.

The median of a set of numbers is the middle value when the numbers are arranged in order. It is not affected by outliers or extreme values as much as the mean is.

If the number 1772 was accidentally changed to 1972, this would increase the value of the number and it would become an outlier in the set. To calculate the median, we need to arrange the numbers in order. The new set would be:

1362 1439 1460 1614 1666 1867 1972

The median of this set is 1614, which is the middle value. As you can see, the change from 1772 to 1972 did not affect the median.

P(k = 0) = [tex]\frac{2^{0}e^{-2}}{0!}[/tex] = 0.1353

P(k = 1) = [tex]\frac{2^{1}e^{-2}}{1!}[/tex] = 0.2706

P(k = 2) = [tex]\frac{2^{2}e^{-2}}{2!}[/tex] = 0.2706

P(k = 4) = [tex]\frac{2^{4}e^{-2}}{4!}[/tex] = 0.0902

The Probability = P(k = 0) + P(k = 1) + P(k = 2) + P(k = 3) + P(k = 4)

The Probability = 0.1353 + 0.2706 + 0.2706 + 0.1804 + 0.0902

The Probability = 0.9471

(b) We have to determine the probability that the number of backward jumps N it takes her to jump over 9 for the first time (in backward direction), is exactly 4.

The values of x and y in the triangle are 2√30 and 2√21

The value of y

From the question, we have the following parameters that can be used in our computation:

y : 6 = 14 : y

Express as fraction

y/6 = y/14

So, we have

y^2 = 14 * 6

Evaluate

y = 2√21

For the value of x

Here, we have

x^2 = y^2 + 6^2

So, we have

x^2 = (14 * 6) + 6^2

Evaluate

x^2 = 120

So, we have

x = 2√30

Polynomials are mathematical expressions that consist of variables raised to a power and combined with coefficients. The degree of a polynomial is the highest power of the variable in the expression. The number of terms in a polynomial is the number of separate terms that are added together to form the polynomial.

Here are some common examples of polynomials classified by degree and number of terms:

Degree 1, one term: a linear polynomial, such as 3x + 4

Degree 2, one term: a constant polynomial, such as 25

Degree 2, two terms: a quadratic polynomial, such as 3x^2 + 4x + 5

Degree 3, three terms: a cubic polynomial, such as 2x^3 + x^2 + 4x + 7

Degree 4, four terms: a quartic polynomial, such as x^4 + 3x^3 + 4x^2 + 2x + 6

When graphing a function, the input values are the independent variable(s) and the output values are the dependent variable(s).

A graph is a visual representation of a function that helps to understand the relationship between the input and output values of the function. In a graph, the horizontal axis represents the input values, and the vertical axis represents the output values. Each point on the graph represents a single pair of input and output values, and the entire graph represents the entire set of input and output values of the function.

When graphing a function, the input values are the independent variable(s) and the output values are the dependent variable(s).

For example, in the case of a simple linear function such as y = f(x) = 5x + 4, the input value is x, and the output value is y. To create the graph of this function, you would plot a set of ordered pairs (x, y), where x is the input value and y is the corresponding output value.

Similarly, in the case of a multi-variable function such as z = f(x, y), the input values are x and y, and the output value is z. To create the graph of this function, you would plot a set of ordered triples (x, y, z), where x and y are the input values and z is the corresponding output value.
