Rounding to the nearest tenth, we get that the length of KN is approximately 21.8.
What is a Pythagoras theorem?
The theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. This relationship is often expressed in the form of the equation:
a² + b² = c²
To find the length of KN in this right triangle, you can use the Pythagorean theorem. This theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
In this case, the hypotenuse is KL, and the other two sides are KM and KN. The theorem can be written as:
KL² = KM² + KN²
Substituting the given values, we get:
24² = 10² + KN²
Solving for KN, we get:
KN² = 24² - 10²
= 576 - 100
= 476
KN = √476
= 21.84
Hence, rounding to the nearest tenth, we get that the length of KN is approximately 21.8.

Find the coordinate using the subtraction method
-2x+9y=-9
-3x+5y=12
Answers
The co-ordinates will be(x,y) by the given equation the co-ordinates (9,1).
How to co-ordinate using subtraction method?
The technique of subtracting one vector's coordinates from another vector's coordinates is known as vector subtraction.Addition is represented by travelling up the -axis and to the right on the -axis. Subtraction is represented by going left and down the -axis. Since we are travelling below, we can deduct from our coordinate point, and since we are heading rightward, we can add to it.So, the given equations are
-2x+9y=-9 ⇒ (i)
-3x+5y=12 ⇒ (ii)
(i) * 5 ⇒ -10x + 45y = -45
(ii) * 9 ⇒ -27x + 45y = 108
⇒ 17x = 153
x = 9
Now, substitute x=9 in equation (i)
-2(9) + 9y = -9
-18 + 9y = -9
9y = -9 + 18
y = 9/9
y = 1
Hence, the co-ordinates will be(x,y) by the given equation the co-ordinates (9,1).

Answers
Identify the points on the original figure.
Apply the transformation to each point to find the corresponding point on the image.
Connect the points on the image to form the image of the figure.
Here are the steps for each of the transformations you listed:
translation: (x, y) →(x+3, y-5)
To perform this transformation, we need to shift each point 3 units to the right and 5 units down. For example, if the original figure has a point at (1, 2), the image of that point would be at (1+3, 2-5) = (4, -3).
92.) translation: (x,y) →(x,y -2)
To perform this transformation, we need to shift each point 2 units down. For example, if the original figure has a point at (1, 2), the image of that point would be at (1, 2-2) = (1, 0).
reflection across x = -2
To reflect a figure across the line x = -2, we need to negate the y-coordinates of each point. For example, if the original figure has a point at (1, 2), the image of that point would be at (1, -2).
94.) reflect across y = 1
To reflect a figure across the line y = 1, we need to negate the x-coordinates of each point. For example, if the original figure has a point at (1, 2), the image of that point would be at (-1, 2).
rotation 180° about the origin
To rotate a figure 180° about the origin, we need to negate both the x- and y-coordinates of each point. For example, if the original figure has a point at (1, 2), the image of that point would be at (-1, -2).
rotation 90° counterclockwise about the origin
To rotate a figure 90° counterclockwise about the origin, we need to swap the x- and y-coordinates of each point and negate one of them. For example, if the original figure has a point at (1, 2), the image of that point would be at (-2, 1).
I hope this helps! If you provide the points on the original figure, I can help you graph the image for each of the transformations.
The image after the transformations of rotation, translation or reflection can be found by certain operation or rotation.
We can find how to know the image of certain figures after the given transformations are done.
91) Here it is translation.
x coordinates are shifted to right by 3 units and y coordinates are shifted to down by 5 units.
So the entire graph will be shifted to right by 3 units and down by 5 units.
92) Here, the translation is by not shifting the x coordinates and shifting the y coordinates 2 units to the down.
So the entire graph will be shifted to down by 2 units.
93) When a graph is reflected across x = -2, then the graph is moved horizontally such that the original figure and the image will be at the same distance from x = -2.
94) When a graph is reflected across y = 1, then the graph is moved vertically such that the original figure and the image will be at the same distance from y = 1.
95) When a graph is rotated about the origin 180°, if it is clockwise or anticlockwise, each of the coordinates (x, y) in the graph will become (-x, -y).
96) If the rotation is 90° counterclockwise about the origin, the coordinates (x, y) in the original graph becomes (-y, x).

Answer:
8m = 800cm
8m = 0.008km
Step-by-step explanation:
1 kilometer is 1000 meters
1 meter is 100 centimeters
You'd only have to multiply in the first one:
[tex]8 \times 100 = 800[/tex]
8m = 800cm
Remember that when multiplying by 100 you only have to add zeros.
For km, as it is bigger than m you have to divide by 1000, when dividing this time you only have to carry an imaginary point starting from right to left, the amount of zeros there are:
[tex]8. \\ .8 \\ .08 \\ .008 \\ 8 \div 1000 = .008[/tex]
8m = 0.008km
If you run out of numbers when carrying the point, just add zeros.

The slope is m = RISE / RUN, and the change in y is frequently referred to as "RISE."
Step-by-step explanation:[tex]5*x-6*y-(42)=0[/tex]
Tiger understands that this is a straight line equation. Typically, this equation is expressed as y=mx+b (or "y=mx+c" in the UK).
A straight line drawn using the Cartesian coordinate system has the formula "y=mx+b," where "y" denotes the vertical axis and "x" denotes the horizontal axis.
In this equation, y represents how high the line rises, x represents how far it travels along, m represents the slope or gradient, or how steep the line is, and b represents the Y-intercept, or the point at which the line crosses the Y axis.
The X, Y, and slope are collectively referred to as the line properties. We will now plot the line 5x-6y-42 = 0 and determine its characteristics.
x = 0 the value of y is 7/-1 so this line "cuts" the y axis at y=-7.00000
y-intercept = 42/-6 = 7/-1 = -7.00000
y = 0 the value of x is 42/5 Our line therefore "cuts" the x axis at x= 8.40000
x-intercept = 42/5 = 8.40000
Slope = 1.667/2.000 = 0.833 x-intercept = 42/5 = 8.40000 y-intercept = 42/-6 = 7/-1 = -7.00000To learn more about 5x+6y=-42 refer to:

A recipe calls for 3/2 cups of flour. You only have a 1/2 cup measuring cup. What fraction of a cup of flour, in halves, do you need?
Answers
To obtain an amount of 3 / 2 cups of flour, then we need three halves of cup by means of a 1 / 2 cup measuring cup.
How many cups are needed to get the require amount of flour
In this problem we have the case of recipe that requires 3 / 2 cups of flour in terms of certain number of measuring cups with an amount of 1 / 2 cups. The number of measuring cups (n) is equal to the total required by the recipe (M) divided by the amount of the measuring cup (m), both in cups. That is:
n = M / m
If we know that m = 1 / 2 cup and M = 3 / 2 cup, then the number of measuring cups is:
n = (3 / 2 cup) / (1 / 2 cup)
n = 3
In other words, we need 3 halves of a cup of flour to obtain the required amount of 3 / 2 cups.
