To find the highest common factor (HCF) of two polynomials, we can use the Euclidean algorithm or the method of factoring the polynomials and comparing their common factors.

The first polynomial is x² - 2x - y² + 4y-3 and the second polynomial is x² + 2x - y² + 8y-15

x² - y² is common in both polynomials, let's factor it out.

x² - y² = (x-y)(x+y)

so the first polynomial can be written as (x-y)(x+y) - 2x + 4y - 3

and the second polynomial can be written as (x-y)(x+y) + 2x + 8y - 15

So the HCF of these two polynomials is (x-y)(x+y)

It is important to note that the HCF of polynomials is not unique, there can be more than one factorization.

The y-intercept is the y-value of the point at which the line crosses the y-axis.

Therefore, from inspection of the given graph, the y-intercept is 12:

The slope of a line is the change in y over the change in x.

From inspection of the given graph, the change in y is -3 and the change in x is 90.  Therefore, the slope is:

Substitute the found values of m and b into the slope-intercept formula to create an equation of the line:

Three skeins are the most Sharon can afford to purchase because a number of skeins have to be a whole number.

For her sister's birthday present, Sharon has a budget of no more than $25. Sharon is therefore limited to spending no more than $25. She has paid $14.99 for a knitting machine for her. She wants to get her sister some yarn skeins to go with it as well. Cost per skein is $2.75. Let y be the number of yarn skeins.

The polygon was translated 5 units left and 9 units up using the rule for (x, y) ⇒ (x - 5, y + 9)

Translation is the movement of a point in the coordinate plane either up, left, down or right. Translation is a type of rigid transformation because it preserves both the shape and size of the figure.

Other types of rigid transformations are reflection and rotation.

The points D(5, -10) and T(-9, -6) were translated to give D'(0,-1), T'(-14,3). This means that the translation was 5 units left and 9 units up.

The length of the second side, x, is 12.

What is Pythagoras' theorem?

In a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides (the legs of the triangle). This theorem is usually represented by the equation: a^2 + b^2 = c^2, where c is the length of the hypotenuse, and a and b are the lengths of the legs.

In this case, the first side has a length of 9, the second side has a length of x, and the third side has a length of 15, which is the hypotenuse. We can use the Pythagorean theorem to solve for x:

x^2 + 9^2 = 15^2

x^2 = 15^2 - 9^2

x^2 = 225 - 81

x^2 = 144

x =√144

x = 12

Hence, the length of the second side, x, is 12.

The values of six trig functions are:

sinθ=− √5/5, cosθ=2√5/5, tanθ=-1/2, cot θ=−2, secθ=√5/2, cscθ=−√5

The relationship between the angles and sides of a triangle is given by these trig functions.

There are six functions of an angle commonly used in trigonometry. Their names and abbreviations are sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant (csc).

The point's coordinates are:

x=2, y=−4

To calculate the functions we have to calculate the distance between the point and the origin:

r=√x²+y²=√2²+(−4)²=√16+4=√20

r=2√5

Now we can calculate the functions:

sinθ=y/r=−2/2√5=−√5/5

Each store location would be represented as a separate bar, with each bar displaying the percentage of time spent on each task as stacked sections within the bar.

A stacked bar chart is a type of graph that is used to visualize data. It is a bar chart that displays the relative contribution of different data points to the whole. It is particularly useful for comparing the contribution of different data points across different categories. For example, a stacked bar chart can be used to show the percentage of time spent on different tasks at different store locations. The horizontal axis would represent the store locations, while the vertical axis would represent the percentage of time spent on each task. Each store location would then be represented as a separate bar, with each bar displaying the percentage of time spent on each task as stacked sections within the bar. The colors used to represent each task can be used to make the chart more visually appealing, and help viewers differentiate between the tasks. The stacked bar chart is a useful tool for analyzing data over multiple categories, and can be used to quickly identify trends and patterns.

Answer:

The inequality can be solved by isolating the variable x on one side of the inequality. To do this, we can first add 4x to both sides of the inequality:

-2 ≤ 4x + 3 ≤ 4

Next, we can subtract 3 from both sides of the inequality:

-5 ≤ 4x ≤ 1

Finally, we can divide both sides of the inequality by 4 to solve for x:

x ≥ -5/4 and x ≤ 1/4

So the solution of the compound inequality is x ≥ -5/4 and x ≤ 1/4

We can also express this solution in interval notation: [-5/4, 1/4]

Note that the compound inequality has two separate inequality signs, indicating that the solution is the set of all x-values that make both inequalities true.

The probability of rolling an odd number on a fair six-sided die is P(odd) = (1/6) + (1/6) + (1/6) = 3/6 = 1/2. This is because there are three odd numbers (1, 3, and 5) out of the six possible outcomes, and they are each equally likely to occur.

The probability of rolling a number divisible by 3 on a fair six-sided die is P (divisible by 3) = (1/6) + (1/6) = 2/6 = 1/3. This is because there are two numbers (3 and 6) out of the six possible outcomes that are divisible by 3, and they are each equally likely to occur.

It's important to note that in both of these examples, we are assuming that the die is fair and unbiased, which means that each of the six possible outcomes has an equal chance of occurring. If the die is not fair, the probabilities of each outcome could be different.

Kasey's claim that her model is a good fit for the data is best supported by a correlation coefficient of r = 0.91. The correct answer would be an option (B).

A correlation coefficient (r) is a number between -1 and 1 that measures the strength and direction of a linear relationship between two variables.

A coefficient of r = 1 indicates a perfect positive linear relationship, meaning as one variable increases, the other variable also increases.

A coefficient of r = -1 indicates a perfect negative linear relationship, meaning as one variable increases, the other variable decreases.

A coefficient of r = 0 indicates no linear relationship between the variables.

In this case, a coefficient of r = 0.91 is close to 1 which means that there is a strong positive linear relationship between the data and the model. On the other hand, the other coefficients -0.25, 0.01, and -0.79 are not close to 1, which means that there is no or weak linear relationship between data and the model.

What is the antiderivative of the function?

An antiderivative of a function is a function whose derivative is equal to the original function. It is also known as an indefinite integral of a function with respect to its variable. The process of finding an antiderivative is called integration.

1. The most general antiderivative of the function f(x)=x is F(x) = (1/2)x^2 + C, where C is the constant of the antiderivative. To check this, we can differentiate F(x) using the power rule for derivatives and see if we get back f(x) = x: d/dx [(1/2)x^2 + C] = d/dx (1/2)x^2 + d/dx C = x

2. The most general antiderivative of the function r(θ)=sec(θ)tan(θ)−5e^(θ^3) is R(θ)=∫sec(θ)tan(θ)−5e^(θ^3) dθ = -ln(cos(θ))+5e^(θ^3)/3+C, where C is the constant of the antiderivative. To check this, we can differentiate R(θ) using the rules of integration by substitution, and see if we get back r(θ) = sec(θ)tan(θ)−5e^(θ^3): d/dθ [-ln(cos(θ))+5e^(θ^3)/3+C] = sec(θ)tan(θ)−5e^(θ^3)

3. The most general antiderivative of the function f(x)=1+2x is F(x) = x+x^2 + C, where C is the constant of the antiderivative. To check this, we can differentiate F(x) using the power rule for derivatives and see if we get back f(x) = 1+2x: d/dx (x+x^2 + C) = d/dx x+d/dx x^2 + d/dx C = 1+2x

Hence,

1. The antiderivative would be x.
