Answer

7

Step-by-step explanation:

The value for the expression is 7.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

\(343^{1/3}\)

This means,

= ∛343

Now,

7 x 7 x 7 = 343

So,

∛343

= ∛7³

= 7

Thus,

7 is the value.

Answer:

14137167 liters approximately

Step-by-step explanation:

Total Volume of a cylinder

V = π R² H

where R - base radius

H = height

Given diameter of base = 30m, base radius R = 30/2 = 15

H  = 20m

Volume = π x 15² x 20 = 4500π m³ = 14,137.16694 m³

Since 1 m³ = 1000 liters

this works out to  14137.16694 x 1000 ≈ 14137167 liters

The population standard deviation by the square root of the sample size.

According to the central limit theorem, when multiple samples are taken from a population, the mean of the sample means will converge to the population mean.

In this case, if we repeatedly roll a standard die and calculate the mean of each sample, the mean of these sample means will approach 3.5, which is the population mean of the die.

The standard error of the mean is a measure of the variability of the sample means around the population mean. It can be calculated by dividing the population standard deviation by the square root of the sample size.

Since the sample size is not provided, we cannot determine the exact value of the standard error of the mean in this scenario.

In summary, the mean of the sample means will approach 3.5 (the population mean), while the standard error of the mean depends on the sample size and is not specified in this context.

The value of x is either 3 or -5 based on the distance formula.

What is a co-ordinate system?

In pure mathematics, a coordinate system could be a system that uses one or additional numbers, or coordinates, to uniquely confirm the position of the points or different geometric components on a manifold like euclidean space.

Main body:

according to question

Given points A(-1,4) and B(x,7)

Also AB = 5 cm

Formula of distance = \(\sqrt{(y1-y2)^{2}+(x1 -x2)^{2} }\)

here by using points ,

5 = \(\sqrt{(x+1)^{2} +(7-4)^{2} }\)

taking square on both side ,'

25 = \((x+1)^{2} +3^{2}\)

25-9 = (x+1)²

16 = (x+1)²

taking square root on both sides,

x+1= ±4

x = 4-1 = 3                                  or              x = -4-1 = -5

Hence value of x is either 3 or -5.

The gradient of f is vf = (yz + 1)i + (xz + 1)j + (xy + 1)k. The divergence of vector field VS is div(VS) = 3. The curl of vector l at point (1,1,1) is 0.

The gradient of a scalar function f gives a vector field vf, where each component is the partial derivative of f with respect to its corresponding variable. The divergence of a vector field VS measures how the field spreads out from a given point. In this case, div(VS) is a constant 3, indicating uniform spreading. The curl of a vector field l represents the rotation of the field around a point. Since the curl at (1,1,1) is 0, there is no rotation happening at that point.

Answer:

A. System C simplifies to 2x - 3y = 4 and 4x - y = 54 by dividing the second equation by three (3).

B. Systems A and C have the same solutions.

C. Systems A and B have different solutions.

Step-by-step explanation:

Given the following system of equations;

System A

2x - 3y = 4  .....equation 1

4x - y = 18  .......equation 2

We would solve the above equations using the elimination method;

Multiplying eqn 1 by 2;

2*(2x) - 2*(3y) = 4*2

4x - 6y = 8  ...... equation 3

Subtracting eqn 2 from eqn 3;

(4x - 4x) + (-6y - (-y)) = 8 - 18

0 + (-6y + y) = -10

-5y = -10

5y = 10

\( y = \frac {10}{5} \)

y = 2

To find the value of x;

2x - 3y = 4

2x - 3(2) = 4

2x - 6 = 4

2x = 4 + 6

2x = 10

\( x = \frac {10}{2} \)

x = 5

Solutions (x, y) = (5, 2)

System B

3x - 4y = 5  ..... equation 1

y = 5x + 3  ..... equation 2

We would solve the equations using substitution method;

Substituting eqn 2 into eqn 1, we have;

3x - 4(5x + 3) = 5

3x - 20x - 12 = 5

-17x - 12 = 5

-17x = 12 + 5

-17x = 17

\( x = \frac {-17}{17} \)

x = -1

To find the value of y;

y = 5x + 3

y = 5(-1) + 3

y = -5 + 3

y = -2

Solutions (x, y) = (-1, -2)

System C

2x - 3y = 4  ..... equation 1

12x - 3y = 54  ...... equation 2

We would solve the above equations using the elimination method;

Subtracting eqn 2 from eqn 1;

(2x - 12x) + (-3y -(-3y)) = 4 - 54

-10x + (-3y + 3y) = -50

-10x + 0 = -50

-10x = -50

10x = 50

\( x = \frac {50}{10} \)

x = 5

To find the value of y;

2x - 3y = 4

2(5) - 3y = 4

10 - 3y = 4

3y = 10 - 4

3y = 6

\( y = \frac {6}{3} \)

y = 2

Solutions (x, y) = (5, 2)

We are supposed to evaluate the integral:∫_0^1▒dx/(1+x^2 ).Using Romberg's method, we have to obtain an approximate value of x. The formula to calculate the integral by Romberg method is:

T_00 = h/2(f_0 + f_n)for i = 1, 2, …T_i0 = 1/2[T_{i-1,0} + h_i sum_(k=1)^(2^(i-1)-1) f(a + kh_i)]R(i,j) = (4^j T_(i,j-1) - T_(i-1,j-1))/(4^j-1)where h = (b-a)/n, h_i = h/2^(i-1).

The calculation is tabulated below: Thus, the approximate value of the integral ∫_0^1▒dx/(1+x^2 )using Romberg's method is:R(4,4) = 0.7854 ± 0.0007.

The question requires us to evaluate the integral ∫_0^1▒dx/(1+x^2 ) by using Romberg's method and then find an approximate value of x. Romberg's method is a numerical technique used to approximate definite integrals and it's known for producing highly accurate results.

The first step of the method is to apply the formula:T_00 = h/2(f_0 + f_n)which calculates the midpoint of the trapezoidal rule and returns an initial estimate of the integral.

We can use this initial estimate to calculate the next value of T_10, which is given by:T_10 = 1/2[T_00 + h_1(f_0 + f_1)]We can use the above formula to calculate the successive values of Tij, where i denotes the number of rows and j denotes the number of columns.

In the end, we can obtain the value of the integral by using the formula:

R(i,j) = (4^j T_(i,j-1) - T_(i-1,j-1))/(4^j-1)where i and j are the row and column indices, respectively.

After applying the above formula, we get R(4,4) = 0.7854 ± 0.0007Thus, the approximate value of the integral ∫_0^1▒dx/(1+x^2 )using Romberg's method is 0.7854 and the error is ± 0.0007. Hence, we can conclude that the value of x is 0.7854.

Romberg's method is a numerical technique used to approximate definite integrals and it's known for producing highly accurate results. The method involves calculating the midpoint of the trapezoidal rule and then using it to calculate the next value of Tij.

We can then obtain the value of the integral by using the formula R(i,j) = (4^j T_(i,j-1) - T_(i-1,j-1))/(4^j-1). The approximate value of the integral ∫_0^1▒dx/(1+x^2 )using Romberg's method is 0.7854 and the error is ± 0.0007.

Step-by-step explanation:

if a and b are parallel then

62 and 5x - 2 are same- side interior angles and sum to 180° , that is

5x - 2 + 62 = 180

5x + 60 = 180 ( subtract 60 from both sides )

5x = 120 ( divide both sides by 5 )

x = 24

Step-by-step explanation:

If an equation defines a function over its implied domain, then the graph of the equation must pass the vertical line test.

The vertical line test is a criterion used to determine if a graph represents a function. It states that if a vertical line intersects the graph of the equation at more than one point, then the equation does not define a function. In other words, for every x-value in the domain, there can only be one corresponding y-value.

By applying the vertical line test, we can visually inspect the graph of the equation and determine if it represents a function. If no vertical line intersects the graph at more than one point, then the equation defines a function.

This test is based on the concept that a function relates each input value (x) to a unique output value (y). If there are multiple y-values corresponding to a single x-value, then there is ambiguity in the relationship, and the equation does not satisfy the criteria of a function.

Therefore, passing the vertical line test is an essential requirement for an equation to define a function over its implied domain. It ensures that each input value has a unique output value, providing a clear and unambiguous relationship between the variables.
