-3 is not an irrational number, but it is a real number, a rational number, an integer, and a whole number.  

What are whole numbers and rational numbers?

All numbers, including integers, fractions, decimals, and irrational numbers, that can be represented on a number line are considered real numbers.

In summary, real numbers include rational and irrational numbers, and integers include whole number and their negatives.

When two integers are compared, a number can be stated as a ratio, such as -3/1, 1/2, or 5/7. Writing rational numbers as recurring or ending decimals is an option.

Numbers that can't be stated as a ratio of two integers, like 2 or, are referred to as irrational numbers. It is impossible to write irrational numbers using repeating or ending decimals.

Positive and negative whole numbers, as well as zero, are considered integers. Since whole numbers are non-negative integers, they contain zero and only positive values.

Answer:

(2, -2)

Step-by-step explanation:

To rotate a point in a coordinate plane 90 degrees clockwise, we need to switch the x and y coordinates and negate the new x coordinate.

So let's apply this formula to the point (-2, -2):

- The new x-coordinate will be the original y-coordinate: -2

- The new y-coordinate will be the negation of the original x-coordinate: -(-2) = 2

Therefore, after rotating (-2, -2) 90 degrees clockwise, we get the point (2, -2).

We can visualize this by plotting both points on a coordinate plane and drawing a line of reflection that represents the rotation:

```

Before rotation:

|

|

|

-------+-------

|

(-2,-2)

After rotation:

|

|

(2,-2)|

-------+-------

|

```

As shown in the diagram above, after rotating (-2,-2) 90 degrees clockwise, it lands at (2,-2).

The image was created by translating 5 units down, 5 units up, 1 unit down, and 1 unit up. ABCD and A'B'C'D' are two polygons on the graph.

The first polygon, ABCD, has vertices at (4,4), (12,4), (8,4), and (1,1),). (3,1). The vertices of the second polygon, A'B'C'D', are located at (1,1), (3,1), (3,2), and (1,2). (0.5,.25).

We can establish the translation that was applied to produce the image by comparing the coordinates of the two polygons. The two polygons' initial coordinate is (1,-1) and their second coordinate is (1,-1). (1,-6). The translation is 5 units lower because of the 5-unit difference in the y-coordinate. The second coordinate for the two polygons is (3,-5) and (3,-10). The translation is 5 units lower because of the 5-unit difference in the y-coordinate.

The third coordinate of the second polygon is (7,-5) and (7,-10). The translation is 5 units lower because of the 5-unit difference in the y-coordinate. The fourth coordinate of both polygons is (5,-1). (5,-6). The translation is 5 units lower because of the 5-unit difference in the y-coordinate.

The translation of the image was five units down, five units up, one unit down, and one unit up.

To factor completely using the GCMF (Greatest Common Monomial Factor), we first need to identify the common monomial factor of all three terms. In this case, the common monomial factor is 2x²:

10x^5 + 8x^4 - 4x² = 2x²(5x^3 + 4x^2 - 2)

Now, we can see that the expression can be factored further, but it cannot be factored using the GCMF. However, we can use other factoring techniques, such as grouping or factoring by grouping, to factor the remaining expression:

2x²(5x^3 + 4x^2 - 2) = 2x²(5x^3 + 10x^2 - 6x^2 - 2)

= 2x²(5x^2(x + 2) - 2(x + 2))

= 2x²(5x^2 - 2)(x + 2)

Therefore, the expression 10x^5 + 8x^4 - 4x² can be factored completely as 2x²(5x^2 - 2)(x + 2).

Answer:

Their average velocity during their trip was 59.19 miles per hour.

Step-by-step explanation:

To calculate the average velocity of the family's trip, we divide the total distance traveled by the time it took to travel that distance:

Average velocity = total distance ÷ time

In this case, the total distance traveled is 509 miles and the time it took to travel that distance is 8.6 hours. So, we can plug these values into the formula:

Average velocity = 509 miles ÷ 8.6 hours

Simplifying this equation, we get:

Average velocity = 59.19 miles per hour (rounded to two decimal places)

Therefore, the family's average velocity during their trip was 59.19 miles per hour.

Using Cauchy-Euler equation, the solution of the second-order homogeneous differential equation  is y2(x) = c3 * x^(1/3) + c4 * x^(4/3) - (1/2) * c4 * x

The given LODE is a second-order homogeneous differential equation with constant coefficients. The characteristic equation is given by:

9r^2 - 6r + 2 = 0

Using the quadratic formula, we find the roots to be:

r = (1/3) ± i/sqrt(3)

Thus, the general solution to the differential equation is:

y(x) = c1 * x^(1/3) * cos((1/3)*arccos(sqrt(3)*r)) + c2 * x^(1/3) * sin((1/3)*arccos(sqrt(3)*r))

To find the first solution, we can choose either the cosine or sine term. Let's choose the cosine term for simplicity:

y1(x) = x^(1/3) * cos((1/3)*arccos(sqrt(3)*r))

To find the second solution, we can use the method of reduction of order. Assume that the second solution has the form:

y2(x) = v(x) * y1(x)

Substituting this into the differential equation, we obtain:

9x^2(v''(x)*y1(x) + 2v'(x)*y1'(x) + v(x)*y1''(x)) - 6x(v'(x)*y1(x) + v(x)*y1'(x)) + 2v(x)*y1(x) = 0

Simplifying this equation by dividing by x^2*y1(x), we get:

9v''(x) + (18/r)x*v'(x) + ((2/r^2) - 1)v(x) = 0

where r = sqrt(3)

This is a Cauchy-Euler equation, which can be solved by assuming a solution of the form:

v(x) = x^m

Substituting this into the equation, we obtain:

9m(m-1) + (18/r)m + ((2/r^2) - 1) = 0

Simplifying this equation, we get:

9m^2 + 6m + 1 = 0

Using the quadratic formula, we find the roots to be:

m = (-1/3) or (-1/3)

Thus, the second solution is given by:

y2(x) = c3 * x^(1/3) + c4 * x^(1/3) * ln(x)

To determine the first four leading terms in the second solution, we can use the Taylor series expansion of the natural logarithm:

ln(x) = (x-1) - (1/2)(x-1)^2 + (1/3)(x-1)^3 - ...

Substituting this into the second solution, we obtain:

y2(x) = c3 * x^(1/3) + c4 * x^(1/3) * [(x-1) - (1/2)(x-1)^2 + (1/3)(x-1)^3 - ...]

Simplifying this expression, we get:

y2(x) = c3 * x^(1/3) + c4 * x^(1/3) * (x-1) - c4 * x^(1/6) * (1/2)(x-1)^2 + c4 * x^(1/3) * (1/3)(x-1)^3 - ...

Thus, the first four leading terms in the second solution are:

Given that the circumference of the circle is 20 ft, we can plug in the values into the formula and solve for "r":

20 = 2πr

Divide both sides of the equation by 2π:

r = 20 / (2π)

Simplify the expression by using the approximation of π as 3.14159:

r = 20 / (2 x 3.14159)

r = 3.1831 ft (rounded to four decimal places)

Therefore, the radius of the circle is approximately 3.1831 feet.
