Ordered pairs are also very well known as coordinates.

An ordered pair is a set of two numbers that are used to describe the position of a point on a coordinate plane.

The first number in the ordered pair is called the x-coordinate and the second number is called the y-coordinate. The x and y coordinates represent the horizontal and vertical positions, respectively, of a point on a coordinate plane.

For example, (3,4) is an ordered pair. Here, 3 is the x-coordinate and 4 is the y-coordinate. Point (3,4) is located 3 units to the right of the y-axis and 4 units above the x-axis on a coordinate plane.

The inequality is x ≤ 5.09, where x is the number of outfits. Rashon can buy at most 5 outfits while staying within his budget.

To determine the number of biking outfits Rashon can buy while staying within his budget, you can set up an inequality using the information provided.

First, calculate the total cost of the reflectors and gloves:

3 reflectors × $10.78 + $32.64 = $38.34 + $32.64 = $71

Then, subtract the cost of the bicycle, reflectors, and gloves from Rashon's budget: $780 - $481.28 - $71 = $227.72

Now, you can use this remaining amount to determine the number of biking outfits Rashon can buy.

Let x be the number of outfits he can buy

You can set up an inequality as follows:

44.95x ≤ $227.72

Dividing both sides by 44.95:

x ≤ 5.09

However, since the number of outfits is an integer, he can only buy 5 outfits at most.

The possible rational roots of x³ - x² - 10x - 8 = 0 are -2, -1, and 4.

In mathematics, a root of an equation is a value of the variable that makes the equation equal to zero.

For example, in the equation x² - 4 = 0, the roots are 2 and -2, because when x = 2 or x = -2, the equation is satisfied (2² - 4 = 0 and (-2)² - 4 = 0). In other words, 2 and -2 are the values of x that "cancel out" the equation.

For a polynomial equation, such as x³ - x² - 10x - 8 = 0, the roots are the values of x that make the polynomial equal to zero. In this case, the roots are the values of x that satisfy the equation x³ - x² - 10x - 8 = 0.

The possible rational roots of x³ - x² - 10x - 8 = 0 are the integers that divide 8 and -8 and are also factors of -1. Since 8 and -8 are divisible by 1, 2, 4, and 8, the possible rational roots of the equation are -1, -2, -4, -8, 1, 2, 4, and 8. But among these, only -2, -1, and 4 makes the equation equal to zero.

Hence, -2, -1, and 4 are the possible rational roots of x³ - x² - 10x - 8 = 0.

Answer:

Below

Step-by-step explanation:

This is a right traingle with legs 300 and 2250

Tangent = opp leg / adjacent leg

Arc tan (opp / adj) = arctan (300/2250) = 7.6°

The value of angle D, angle E, angle F are 48° , 84° and 48° respectively

An isosceles triangle is a triangle with two equal sides. In the figure above, the two equal sides have length and the remaining side has length. . This property is equivalent to two angles of the triangle being equal. An isosceles triangle therefore has both two equal sides and two equal angles.

Since E is not equal to F then we can possibly say F = D since the triangle is an isosceles triangle.

Therefore :

180 = 5x+59 + 2x+38 + 2x + 38

180 = 9x + 135

9x = 180-135

9x = 45

x = 5

therefore angle E = 5×5 + 59 = 25+59 = 84°

angle D = F = 2×5 + 38 = 10 + 38 = 48°

therefore D = 48°, E = 84°, F = 48°

227 18-inch cubes can fit inside the rectangular prism.

You may calculate how many 18-inch cubes can fit within a rectangular prism by dividing the rectangular prism's overall volume by the volume of a single 18-inch cube.

A rectangular prism's volume can be calculated using the formula length x width x height. In this instance, the dimensions are 312 inches long, 212 inches wide, and 3 inches high. As a result, the rectangular prism has a volume of 1,326,720 cubic inches (312 x 212 x 3).

A single 18-inch cube has a volume of 18 x 18 x 18 = 5832 cubic inches.

We divide the volume of the rectangular prism by the volume of a single 18-inch cube to get the number of 18-inch cubes that can fit inside: 1,326,720 / 5832 = 227.

Therefore, the rectangular prism can accommodate 227 18-inch cubes.

Please take note that this is an estimate and that there will not be enough room in the prism to fit 227 cubes exactly.

The three types of coordinate input in AutoCAD are absolute coordinates, relative coordinates, and polar coordinates

Absolute coordinates are based on the origin of the drawing, which is the point 0,0. To specify an absolute coordinate, you enter the X and Y coordinates of the desired point. For example, if you want to specify a point at X=4 and Y=6, you would enter ‘4,6’.

Relative coordinates are based on a point relative to the last point specified. To specify a relative coordinate, you enter the distance in the X and Y directions from the last point specified. For example, if you want to specify a point that is 4 units to the right and 6 units up from the last point, you would enter ‘4,6’.

Polar coordinates are based on a distance and an angle from the last specified point. To specify a polar coordinate, you enter the distance and angle from the last point. For example, if you want to specify a point that is 8 units away at an angle of 90 degrees, you would enter ‘8<90’.

The equation of line that passes through (6,0) and has a slope of -5/6 is y = (-5/6)x + 5.

The point-slope form is expressed as;

( y - y₁ ) = m( x - x₁ )

Where m is slope, x₁ and y₁ are the coordinates of the point .

Plug the slope m = -5/6 and point (6,0) into point-slope formula and simplify.

( y - y₁ ) = m( x - x₁ )

( y - 0 ) = (-5/6)( x - 6 )
