Distance between Marvin and Joshua is less or equal to 12 meter.
What is inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Given,
Marvin and Joshua are about to play in a circular field.
Diameter of the field D = 12m
Let distance between two friends is x
Since, Diameter is the longest chord in a circle
Thus, x ≤ D
Distance between two friends ≤ 12 meter.
Hence, Marvin and Joshua are 12 meter or less far away from each other.

What are ordered pairs called?
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.

HELPPP. What is the equation of the line that passes through the point (6,0) and had a slope of -5/6?
The equation of line that passes through (6,0) and has a slope of -5/6 is y = (-5/6)x + 5.
What is the equation of the line that passes through (6,0) and with a slope of -5/6?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 )
y - 0 = (-5/6)x + (5/6)6
y = (-5/6)x + 5

What are the 3 types of coordinate input AutoCAD?
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’.

Triangle BCD has coordinates B(-8,-6), C(-5,2) and D(-2,7). What are the coordinates of D' after a translation of (x,y) -› (x+10, y+1)
Answer:
Step-by-step explanation:
x'=x+10,y'=y+1
so,the x' in D' is -2+10 = 8, y' in D' is 7+1=8
then, the D' is (8, 8)
In the coordinate plane, the point A (1, -4) is translated to the point A'(-3, -5). Under the same translation, the points B (3, -1) and C(4, -7) are
translated to B' and C', respectively. What are the coordinates of B' and C'?
Answer:
B' (- 1, - 2 ) , C' (0, - 8 )
Step-by-step explanation:
A (1 , - 4 ) → A' (- 3, - 5 )
1 → - 3 in the x- direction means subtract 4 from the original x- coordinate
- 4 → - 5 in the y- direction means subtract 1 from the original y- coordinate
the translation rule is then
(x, y ) → (x - 4, y - 1 ) , then applying this
B (3, - 1 ) → B' (3 - 4, - 1 - 1 ) → B' (- 1, - 1 )
C (4, - 7 ) → C' (4 - 4, - 7 - 1 ) → C' (0, - 8 )

Using the distributive property.
How to use distributive property:
Multiply the outside number by the inside parenthesis numbers.
Like this;

What are the possible rational roots of x³ X² 10x 8 0?
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.

The height of the cylinder is 22 inches.
What is height ?
Height, altitude, and elevation all refer to the vertical distance between something's top and bottom or its base and something above it. Height is used to describe everything that may be measured vertically, high or low.
Height is a measurement of vertical distance, or how high something or someone is (how tall they are) (how "high" a point is). For instance, "That building is 50 meters high," or "An airplane flies around 10,000 meters high."
Height is a basic physical characteristic that is commonly expressed in feet (ft) plus inches (in) in the United States and centimeters (cm) in other countries. The SI unit would be meters since these are length measurements. Remember that x feet plus y inches is typically written as x' y.

Suppose that triangle DEF is isosceles with base FD. Suppose also that angle E=(5x+59)° and angle F=(2x+38)°. Find the degree measure of each angle in the triangle
The value of angle D, angle E, angle F are 48° , 84° and 48° respectively
What is an isosceles triangle?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°

Step-by-step explanation:
the point-slope form is
y - y1 = m(x - x1)
m is the slope, (x1, y1) is the given point.
so,
y - -1 = 2(x - 6)
y + 1 = 2(x - 6)
Write an equation in slope form of the line that passes through the given point and is parallel to the graph of the given equation
(-6,-8);y=-4x+2
An equation in slope-intercept form of the line that passes through the given point and is parallel to the graph of the given equation is y = -4x - 32.
What is the point-slope form?Mathematically, the point-slope form of a line is given by this mathematical expression:
y - y₁ = m(x - x₁)
Where:
m represents the slope.x and y are the points.From the given linear equation y = -4x + 2, the slope is given by:
y = -4x + 2
m₁ = -4
In Geometry, two (2) lines are parallel under the following conditions:
m₁ = m₂ (m represents the slope.)
At point (-6, -8), an equation of this line can be calculated in slope-intercept form as follows:
y - y₁ = m(x - x₁)
y - (-8) = -4(x - (-6))
y + 8 = -4(x + 6)
y + 8 = -4x - 24
