A pattern when a binomial can be written as the square of one number minus the square of another number will be 4x² - 9 = (2x-3)(2x + 3)

Binomial is the name for an algebraic expression with only two terms. It is a polynomial with two terms. It is sometimes referred to as the sum or difference of two or more monomials. It is a polynomial's most basic form.

It should be noted that a binomial is an algebraic expression that has two non-zero terms. Examples of a binomial expression: a2 + 2b is a binomial in two variables a and b. 5x³ – 9y² is a binomial in two variables x and y.

In this case, the illustration for 4x² - 9 = (2x-3)(2x + 3) depicts this.

The point (-5,-3) reflected over the y-axis is (5, -3).

There are two ways of reflection.

Along x-axis:

(x, y) – (x, -y)

Along y-axis:

(x, y) - (-x, y)

We have,

(-5, -3)

Now,

Along y-axis:

(x, y) → (-x, y)

So,

(-5, -3) → (-(-5), -3) = (5, -3)

x + (x + 15) = 36

Evaluate the like terms

2x + 15 = 36

2x = 21

x = 10.5

The length of the part of the table that Dina will be painting is 21.991595 feet.

Circumference refers to the distance around the edge of a circle. It is the length of the perimeter of a circle and is defined as the product of the circle's radius and its constant pi (π). The formula for the circumference of a circle is:

C = 2πr

where C is the circumference, π is approximately equal to 3.14, and r is the radius of the circle.

The circumference of a circle is an important concept in geometry, trigonometry, and engineering, as it provides a measure of the size and shape of a circular object. Circumference is used in many applications, such as determining the size of wheels, gears, and other circular objects, as well as in the calculation of areas and volumes of circular shapes.

To find the length of the part of the circular table that Dina will be painting, we need to find the circumference of the circle.

Circumference = 2 * π * r

Where r is the radius of the circle. In this case, the radius is 3.5 feet, so:

Circumference = 2 * π * 3.5

Circumference = 2 * 3.14159 * 3.5

Circumference = 21.991595 feet (to 4 decimal places)

So, the length of the part of the table that Dina will be painting is 21.991595 feet.

The intersection points are (6, 6) and (-6, -6).

What is Intersection points?

The point at which two lines or curves intersect is referred to as the point of intersection. The point at which two curves intersect is crucial because it is the point at which the two curves take on the same value.

The given curves are the polar equations of two circles with radii 6. To find their intersection points, we can set the two equations equal to each other and solve for Ф.

6 sin(Ф) = 6 cos(Ф)

Dividing both sides by 6 and rearranging terms, we get:

tan(Ф) = 1

This equation has infinitely many solutions, but we are only interested in those that lie in the interval [0, π/2].

Ф = π/4 satisfies this condition and corresponds to the point (6, 6) in Cartesian coordinates.

Since the two curves are circles, they are symmetrical about the origin. Therefore, we can deduce that the other intersection point is (-6, -6).

Therefore, the intersection points are (6, 6) and (-6, -6).

Answer: To find the inverse of the function f(x), we need to switch the roles of x and y, so that x becomes the dependent variable and y becomes the independent variable. Then, we need to solve for x in terms of y.

Let y = √x - 5, then x = y^2 + 5.

To find f^-1(2), we need to substitute 2 for y in the equation x = y^2 + 5:

x = 2^2 + 5 = 9

So f^-1(2) = 9.

This means that the inverse of f(x) at 2 is 9. In other words, if f(x) = 2, then x = 9.

The function can be used to model the exponential growth or decay that occurs in real-life situations that fit this particular pattern is y = 4(-0.4)ˣ + -4

An exponential function is a mathematical function that has the form

=> y = abˣ,

where a is a constant and b is the base of the exponential.

To start, we will use the first point, (1, -1.6), to write an equation that relates x and y. Let's call the constant a in our exponential function "k". Using the point (1, -1.6), we can write the equation:

=> -1.6 = k * b¹

Next, we will use the second point, (2, -0.64), to write another equation that relates x and y. Using the point (2, -0.64), we can write the equation:

=> -0.64 = k * b²

Now that we have two equations, we can solve for the two unknowns, k and b, by dividing the two equations:

=> (-0.64) / (-1.6) = k * b² / k * b¹

b = (0.64 / -1.6)¹

b = -0.4

With b determined, we can substitute it back into one of the equations and solve for k:

=> -1.6 = k * (-0.4)¹

=> k = -1.6 / (-0.4)

=> k = 4

So our exponential function that passes through the points (1, -1.6) and (2, -0.64) and has a y-intercept of -4 is:

y = 4 * (-0.4)ˣ + -4

The probability values

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

n = 14

p = 2/14

The probability P(x =1) can be calculated as

P(x) = C(n, x) * p^x * (1 - p)^(n - x)

In this case, we have

P(x = 1) = C(14, 1) * (2/14)^1 * (1 - (2/14))^(13

Evaluate

P(x = 1) = 0.2696

The probability P(x >= 1) can be calculated as

P(x) = 1 - P(0)

In this case, we have

P(x >= 1) = 1 - [C(14, 0) * (2/14)^0 * (1 - (2/14))^(14)]

P(x >= 1) = 0.8845
