The measure of angle x is  30°

Trigonometry is the branch of mathematics that deals with the relationships between the sides and angles of triangles, particularly right triangles. It is concerned with the measurement of angles and the calculation of sines, cosines, and tangents of those angles.

These ratios are known as trigonometric functions and they are used to relate the ratios of the sides of a right triangle to the angles opposite or adjacent to the right angle.

cos(x) = (√3)/2

x = cos⁻¹((√3)/2) = 30°

The relation between effort force and the force of gravity can be represented as,   Fₐ < Fₙ

The definition of force is the pushing or pulling of anything. Push and pull are the result of two things interacting with one another. Stretch and crush are two more phrases that can be used to describe force.

Given that,

A student lifts up a spring scale attached to a block on a table

The block is still resting on the table

The relation between effort force to the force of gravity = ?

Suppose,

The effort force = Fₐ

The force of gravity =  Fₙ

block is still resting on the table,

it means effort force is less than the force of gravity,

To move upward, it is required to apply more effort force,

but, here effort force is less

So, It can be written as,

Fₐ < Fₙ

Hence, the relation between both the forces is  Fₐ < Fₙ

Because a cubic function is a polynomial function, which are continuous curves, the domain of a cubic function is all real numbers.

All odd-degree polynomials have at least one real root; a cubic function has one to three real roots, which may or may not be distinct. A cubic function's graph always has one inflection point. It might have a local minimum and local maximum as its two critical points.

The cubic function [tex]f(x) = x^3 + x^2 + x + 1[/tex]  has a local maximum at x = 1 and a local minimum at x = 1/3. A cubic function can also have two local extreme values (1 max and 1 min).

a) The y-intercept of the line is 25.66, which represents the predicted number of wins when yards allowed is 0.

b) The Seattle Sea hawks, the observed number of wins (10) is 4.12 less than the predicted number of wins based on the least-squares regression line.

c) It will increase the R-Sq and R-Sq(adj) and decrease the S.

The equation of the least-squares regression line is given by:

Number of wins = 25.66 - 0.003131 * (Yards_allowed)

This equation shows the relationship between the number of wins for a team (the dependent variable) and the number of yards allowed by the team (the independent variable).

The slope of the line is -0.003131, which means that for every 1 yard increase in yards allowed, the number of wins decreases by 0.003131. The y-intercept of the line is 25.66, which represents the predicted number of wins when yards allowed is 0.

b) To calculate the residual for the Seattle Seahawks, we can use the equation of the least-squares regression line and the data for the team:

Residual = Observed value - Predicted value

Residual = 10 - (25.66 - 0.003131 * 4668)

Residual = 10 - (25.66 - 14.12)

Residual = -4.12

This means that for the Seattle Seahawks, the observed number of wins (10) is 4.12 less than the predicted number of wins based on the least-squares regression line.

c) The point representing the Carolina Panthers (5167 yards allowed, 15 wins) has a positive effect on the equation of the least-squares regression line because it is above the line.

This means that the team performed better than expected based on the number of yards allowed. Since this point is an outlier, it will increase the R-Sq and R-Sq(adj) and decrease the S.

The greatest common factor of the expression 5x²a + 5xa² is 5xa

To find the greatest common factor (GCF) of the expression 5x²a + 5xa², we need to find the greatest term that can divide into both terms in the expression.

In this case, the GCF is 5xa, as it can divide into both 5x²a and 5xa².

We can check this by dividing both terms with 5xa:

5x²a + 5xa² = (5xa)(x) + (5xa)(a) = 5xa (x + a)

Thus, the GCF of 5x²a + 5xa² is 5xa.

Answer:

a = 6 , b = 17

Step-by-step explanation:

using Pythagoras' identity.

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

using right triangle ABD , then

a² + 8² = 10²

a² + 64 = 100  ( subtract 64 from both sides )

a² = 36 ( take square root of both sides )

a = [tex]\sqrt{36}[/tex] = 6

using right triangle ABC

note that BC = a + 9 = 6 + 9 = 15

b² = 8² + 15² = 64 + 225 = 289 ( take square root of both sides )

b = [tex]\sqrt{289}[/tex] = 17

Answer: Murr's annual social security deduction is the amount of money he pays in social security taxes. Social security tax is 6.2% of Murr's annual salary. To find the annual social security deduction, we can multiply Murr's annual salary by the social security tax rate:

57,285.50 x 6.2% = 3,541.829

Murr's annual social security deduction is 3,541.829

Note that Medicare tax is 1.45% and it's calculated separately, if you want to calculate it you can use the same formula:

57,285.50 x 1.45% = 829.4078

So the total Social security and Medicare tax is 3,541.829 + 829.4078 = 4,371.2368

It's important to note that these are the federal Social Security and Medicare taxes, there might be additional state taxes or deductions that are not included.

This could result in an unexpected transformation. Therefore, the order of the matrices must be taken into account when combining them.

Matrix is a mathematical entity composed of elements arranged in rows and columns. It is used to represent and manipulate various types of data and is commonly used in scientific and engineering applications. Matrices are useful for representing linear equations and transformations of vector spaces, such as scaling and rotation. They can also be used to store data and perform calculations on that data.
Matrix A is a scaling matrix which is used to change the size of an object. This transformation is achieved by multiplying each component of the vector by a value, resulting in a larger or smaller object.

Matrix B is a rotation matrix which is used to rotate an object. This transformation is achieved by multiplying each component of the vector by a coefficient which is then added to the other components, resulting in a rotated object.

Matrix D is a combination of matrices A and B, where the effects of matrix A are applied first and then the effects of matrix B are applied. Care must be taken when combining the two matrices because the order of the transformations matters; applying the effects of matrix B first would result in a different transformation than applying the effects of matrix A first. If matrix B is applied first, it will rotate the object before it is scaled, meaning that the scaling will be applied to the already-rotated object. This could result in an unexpected transformation. Therefore, the order of the matrices must be taken into account when combining them.

(a) A basis for a subspace is a set of linearly independent vectors that span the subspace. To find a basis for this subspace, we can use the following steps:

Write the given set of vectors as the rows of a matrix, with each vector as a row.

Use row-reduction (Gaussian elimination) to put the matrix in row-echelon form.

The non-zero rows of the row-echelon form matrix form a basis for the subspace.

So, we get the matrix:

| 6a - 2c | -5b - 5c | -6a + 5b + 2c | -6a + 2c |

Using row-reduction, we can simplify the matrix to:

| 1 - 1/3 | 0 | 1/3 | -1/3 |

The non-zero rows are {[ 1 - 1/3 0 1/3 -1/3 ]}

So, a basis for the subspace is:

{[ 1 - 1/3 0 1/3 -1/3 ]}

(b) The dimension of a subspace is the number of linearly independent vectors in a basis for the subspace. In this case, the basis for the subspace has only one vector, so the dimension of the subspace is 1.
