In transformations, a line of _____ is also a perpendicular bisector.

The category of the expression x⁴ + 2x³ - x² + 7x + 11  is not quintic binomial

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

x^4+2x^3-x^2+7x+11

Rewrite this expression properly

So, we have the following representation

x⁴ + 2x³ - x² + 7x + 11

The degree of the above polynomial is 4

As a general rule, a quintic binomial is any polynomial that has a degree of 5

A degree of 5 and a degree of 4 are not the same

Hence, the expression is not a quintic binomial

For both the experienced bricklayer and her apprentice working together it will take 2 hours to complete the work.

This is type of combined rate or time and work problem. Here, the experienced bricklayer takes 3 hours and apprentice take 6 hours to complete the job. So the experienced bricklayer completes 1/3rd of work in an hour and her apprentice completes 1/6th of work in an hour.        

Let us consider they would take x hours to complete the work together. The work done is the summation of product of time taken by each person to do the work and the rate of work done by each person.

When we say, "a system of linear equations works" it means that the linear equations share one or more ordered pairs (x,y) when graphed.

In many practical applications in daily life, linear equations are a crucial tool in science. They enable scientists to, among other things, make predictions, compute rates, and characterize relationships between two variables in the physical world. In order to see trends, linear equations are often graphed.

Slope intercept form, direct variation, point slope form and standard form are four types of linear functions.

When we have a system of linear equations and when we solve them simultaneously we get one or more ordered pair depending upon the variable in system.

According to Hooke's law, a material's strain will increase in direct proportion to its applied stress up to its elastic limit. When elastic materials are stretched, atoms and molecules deform up to a point of stress, after which they return to their original shape.

Hooke's law only approximates in first-order linear terms how springs and other elastic bodies actually react to applied forces. Since no material can be stretched or squeezed beyond a given size without permanently deforming or changing its condition, it must inevitably fail once the forces reach a certain threshold.

Many substances will diverge from Hooke's law clearly before they reach such elastic limits.

On the other hand, as long as the forces and deformations are small enough, Hooke's law provides a close approximation for the majority of solid bodies. Since it is the basis of many fields including seismology, molecular mechanics, and acoustics,

Hooke's law is widely applied in all branches of science and engineering. It.

Hence, a material's strain will increase in direct proportion to its applied stress up to its elastic limit. When elastic materials are stretched, atoms and molecules deform up to a point of stress, after which they return to their original shape.

Angles categorized in 45° and 90° are ∠DBC = ∠BDC =∠BAC = 45° and

∠ABC = ∠AED = 90° respectively.

Square is a polygon which has 4 sides. All four sides of square are equal length and perpendicular to each other that means the angle between two adjacent side is 90°.

Given that ABCD is a square surface. And diagonal of square creates two isosceles triangles.

So the ∠ABC = ∠BCD = ∠CDA = DAB = 90°

Here, BD and AC are two diagonals of a square ABCD and E is the intersection point of diagonals.

Diagonals cut each other perpendicular.

So, ∠AED = 90°  and ∠EAD = ∠EDA = 45°

Now to find ∠BAC;

we have ∠ABC = 90° so from the property of isosceles triangle

∠BAC = ∠BCA = 45°

In isosceles triangle BCD,

∠BCD = 90° and ∠DBC = ∠BDC = 45°

Therefore, the angles categorized in 45° and 90° are ∠DBC = ∠BDC =∠BAC = 45° and ∠ABC = ∠AED = 90° respectively.

Answer:

m= -1

Step-by-step explanation:

A line's angle of slope between two points is (5, -4)

A line's angle of slope between two points is given as follows:

m = y2-y1/x2 - x1

A line passing through a given point and having the following equation:

y - y₁ = m(x - x₁)

Line A:

m = -1 - 5 /3- (-1) = -6 /4 = -3/2

y - 5 = -3 / 2(x +1)

y = -3/2 (x + 1) + 5.

Line B:

m = -1-2/6-7  = -3 / -1 = 3

y - 2 = 3 (x - 7)

y = 3(x -7) + 2.

Point of intersection denotes identical x and y coordinates.

So:

3(x - 7)+ 2 = -3/2 (x + 1 ) +5

3x - 21 + 2 = -3/2x - 3/2 +5

3x - 19 = -3/2x + 7/2

6x - 38 = 3x +7

6x + 3x = 7 + 38

9x =45

x = 5

The slope of the line y = 14x – 1 is 14.

To find the slope of a line, we need to know two points on the line. We can choose any two points, as long as they are not the same. For example, we can choose the points (0, -1) and (1, 13):

y = 14x – 1

y = 14(0) – 1 = -1 when x = 0

y = 14(1) – 1 = 13 when x = 1

The slope of the line is the change in y divided by the change in x between these two points. In this case, the change in y is 13 – (-1) = 14, and the change in x is 1 – 0 = 1. Therefore, the slope of the line is 14/1 = 14.

We can also write the slope as a simplified fraction. In this case, 14 is already a simplified fraction, so we don't need to simplify further. Therefore, the slope of the line y = 14x – 1 is 14.

The inequality on the graph is a linear inequality, and it can be written as:

y > 2x - 4

On the graph, we can see a linear inequality, we can see a dashed line with a positive slope, and the shaded area is above that line, so the inequality is of the form:

y > line.

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through two points (x1, y1) and (x2, y2), then the slope is:

a = (y2 - y1)/(x2 - x1)

We can find two points on the graph, we can see that the line passes through (0, -4) and (2, 0), then the y-intercept is -4 and the slope is:

a = (0 + 4)/(2 - 0) = 2

Answer: If a1 = 16 and a2 = -8, then we can write a recursive formula for the nth term of the sequence as follows:

an = a(n-1)/2

This formula states that the nth term of the sequence is equal to the previous term (n-1) divided by 2. For example, if n = 3, then a3 = a(3-1)/2 = a2/-8/2 = 4.

We can also write this formula in terms of the initial values of the sequence as follows:

a(n) = (-1)^(n-1) * 8

This formula states that the nth term of the sequence is equal to (-1) raised to the power of (n-1), multiplied by 8. This formula will always give the correct value for the nth term of the sequence, regardless of the initial values of the sequence.

Error bars are graphical representations of data variability that are used to indicate the error or uncertainty in a reported measurement on graphs.

The estimated error in a measurement is indicated by error bars. In other words, an error bar represents the degree of uncertainty in a value.

When the standard deviation error bars overlap significantly, it is an indication that the difference is not statistically significant. To reach a conclusion, you must conduct a statistical test.

When the standard deviation error bars overlap even less, it indicates that the difference is unlikely to be statistically significant.
