How to learn tables 1 to 10?
One of the most effective techniques to recall multiplication tables without just repeating the numbers is by using skip counting.
what is sequence ?A sequence is a group of numbers, or "terms," as 2, 5, 8. Some sequences can be made endlessly long by taking advantage of a specific pattern they follow. Add three and use the example of 2,5,8 to continue the series. There are formulas there that demonstrate where to look for words within a sequence. A collection of objects that are in some order is referred to as a sequence informally in mathematics. It has parts, much like a set. The entire, potentially infinite number of ordered objects is referred to as the sequence's length. putting two or more items in a sensible order. Chronological.

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
Therefore, the equation of the line is y = (-5/6)x + 5.

How do you find the center of dilation of two lines?
Finding the center of dilation of two lines involves determining the point that is equidistant from the two lines.
A dilation is a transformation that changes the size of an object, but not its shape, and the center of dilation is the point from which the object is scaled.
The center of dilation of two lines can be found by constructing a line perpendicular to both lines that bisects the angle between them. The point of intersection of this line with the segment connecting the two closest points on the two lines is the center of dilation.
To find the center of dilation, we can use the following steps:
1. Draw the two lines and find the angle between them.
2. Draw a line perpendicular to both lines and bisecting the angle between them.
3. Draw the segment that connects the two closest points on the two lines.
4. The intersection of the line from step 2 with the segment from step 3 is the center of dilation.
It's also possible to use vector and linear algebra to find the center of dilation for two lines. By finding the slope of each line and their intersection point, the center of dilation can be found as the midpoint of the intersection point of the two lines.
In conclusion, finding the center of dilation of two lines requires determining the point that is equidistant from the two lines.
It can be done by drawing a line perpendicular to both lines that bisects the angle between them, or by using vector and linear algebra to find the intersection point of the two lines and finding the midpoint of that point.

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.

No, a triangle with sides 25 cm, 5 cm and 24 cm does not make a right triangle as these lengths does not adhere to the Pythagorean theorem.
A right triangle has one angle that measures exactly 90 degrees. In a triangle, the longest side (the hypotenuse) is opposite the right angle.
The Pythagorean theorem states that in a right triangle, the sum of the squares of the two shorter sides (legs) is equal to the square of the hypotenuse.
In this case, the side lengths do not satisfy the Pythagorean theorem, as (24^2 + 5^2 = 601) ≠ (25^2 = 625)

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

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.

The 3 types of 3-dimensional coordinate systems are the x-axis, the y-axis, and the z-axis.
The Cartesian coordinates of a point in three dimensions are a triplet of numbers (x,y,z). The three numbers, or coordinates, specify the signed distance from the origin along the x,y, and z-axes, respectively.
The three axes intersect at the point called the origin. The x-axis is the horizontal line along which the wall to your left and the floor intersect.
The y-axis is the horizontal line along which the wall to your right and the floor intersect. The z-axis is the vertical line along which the walls intersect.
To locate the point (a, b, c), we can start at the origin O and move units along the x-axis, then b units parallel to the y-axis, and then c units parallel to the z-axis.

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’.
