Use one or more transformations to transform the pre-image (purple) onto the image (white).
Transformations in geometry include translation, rotation, reflection, and dilation, which are used to change a figure's position, orientation, or size. The appropriate transformation to use depends on the changes observed between the purple pre-image and the white image in the problem.
Explanation:In mathematics, specifically in geometry, we use transformations to move or change a figure in some way without altering its fundamental shape or size. The transformation of a pre-image onto an image can be achieved using transformations such as translation, rotation, reflection, or dilation.
To transform the purple pre-image onto the white image, firstly identify the type of transformation required. For instance, if the white image is the same size as the purple pre-image and only its position has changed, use translation. If the image is mirrored along a line, use reflection. If it's turned around a point, use rotation. If the image is an enlarged or reduced version of the original figure, use dilation.
Consequently, the precise steps depend on the type of transformation(s) required.

Orlando is making a design for a logo. He begins with a square measuring 22 inches on a side.
The second square has a side length of 17.6 inches, and the third square has a side length of
14.08 inches. Which square will be the first square with a side length of less than 10 inches?
A) fifth square
B) fourth square
C) sixth square
D) seventh square
Answer: A
Step-by-step explanation:
The first square is 22 inches on a side.
The second is 17.6 inches on a side
the third is 14.08 inches on a side.
We can suppose that we have a constant rate of decrease betwen the sides cubes, this means that:
22in*x = 17.6in
where x is the rate of scale.
x = 17.6/22 = 0.8
Now we test this with the second and third:
17.6in*0.8 = 14.08in
Ok, this works.
then the side of n-th cube can be found with the equation
L = 22*0.8^(n-1)
we can try the different options and see which one gives a value smaller than 10.
A) n = 5
L = 22*0.8^4 = 9.01
Then the correct option is A

Do you mean D for the last choice?
The answer is D, if that is what you meant.
The 1/4 must be positive since the 1/2 is positive in the equation and the second numbers are all positive in the choices.
Also, 1/4 of 2 is 1/2, so D has to be the answer.

A circular pool has a radius of 10 feet. What is the areaof the surface of the water in the pool? Use 3.14 for π.
Answer:
314ft²
Step-by-step explanation:
A = πr²
A= π10²
A=100π
A=100*3.14
A=314
Hope this helps :)
Final answer:
To calculate the area of the circular pool's surface, use the formula A = πr² with π approximated as 3.14 and the given radius of 10 feet. The area is 314 square feet, as the calculation yields A = 3.14 × 100, which does not need adjustment for significant figures.
Explanation:
To find the area of the surface of the water in the circular pool with a radius of 10 feet, we use the formula for the area of a circle, which is A = πr². Let's use the given value for pi (π) as 3.14 and the radius (r) is 10 feet. So the calculation is A = 3.14 × (10 feet)².
Now, squaring the radius, we get (10 feet)² = 100 feet². Next, we multiply this by our value for pi, resulting in A = 3.14 × 100 feet² = 314 feet². Therefore, the area of the surface of the water in the pool is 314 square feet.
Recalling significant figures, since our given radius was precise to two significant figures, our final answer should also reflect two significant figures. However, since all the numbers in 314 are significant, there is no need for adjustments in this case, and the result remains 314 square feet.
Solve the following system:
y=1
y=-6x-5
Answer:
x = -1
y = 1
Step-by-step explanation:
Since it gives you "y", plug in the number given into the equation:
y = -6x - 5
1 = -6x - 5
Then, add 5 to both sides:
1 = -6x - 5
+5 + 5
________
6 = -6x
Divide both sides by -6:
6 = -6x
-1 = x
So now you have, x = -1 and y = 1
Ryan invests a sum of money in a savings account with a fixed annual interest rate of 4.31% compounded 12 times per year. After 10 years, the balance reaches $12,855.94. What was the amount of the initial investment?
Based on the information given the amount of the initial investment is $8,361.
Let P represent the amount of the initial investment
Hence,
12855.94 = P(1 + .0431/12) ^12(10)
12,855.94=P(1+0.0035917)^120
12,855.94=P(1.0035917)^120
12,855.94=P(1.53760782)
P=12,855.94/1.53760782
P=$8,360.8
P=$8,361 (Approximately)
Inconclusion the amount of the initial investment is $8,361.

What Values of X will make x2 (Exponent of 2) =16 true? HELPPPPPP!!
A)4 AND -4
B)2
C)4
D)6 AND -6
Answer:
A
Step-by-step explanation:
Given
x² = 16 ( take the square root of both sides )
[tex]\sqrt{x^2}[/tex] = ± [tex]\sqrt{16}[/tex] ← note plus or minus sign
x = ± 4
Since 4² = 4 × 4 = 16 and
(- 4)² = - 4 × - 4 = 16
Work out the gradient of a line that is parallel to -2x+y-5=0
Answer:
gradient = 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the gradient and c the y- intercept )
Given
- 2x + y - 5 = 0 ( add 2x and 5 to both sides )
y = 2x + 5 ← in slope- intercept form
with gradient m = 2
Parallel lines have equal gradients
Gradient of parallel line is m = 2

interest according to the function s(x) = (1.03)* - 1. After combining the two functions, the new function is g(x) = 103(1.03)* - 1. Using complete sentences, explain what the 103 represents in this new function. What is the interest rate the bank is giving to Victoria?
103 represents how much money Victoria is depositing into the bank, or her principal.

M = 8 x 7
T = 56.
A sign is in the shape of a triangle. It has a base of 12 inches and an area of 120 square inches. What is the height of the sign?
Answer:
The height is 20
Step-by-step explanation:
This is because 120= .5x12
which equals 120= 6. Of course this is not equal so we do 120/6= 20.
Now if we insert 20 to check .5x12x20= 20 which makes the statement true
Answer: 20
Step-by-step explanation: 120 divided by 3 = 40 half of 40 is 20
Electricity City increases the price of televisions by 25%. If a television now sells for
$425, what was the original price?
Answer:
340
Step-by-step explanation:
As it was increased by 25%, $425 is 125% of the original price, so we can get back to 100% by dividing 425 by 5 [85], so 85 is 25% of the price. We can now get the original price by subtracting 85 from 425 (or you could multiply 85 by 4) which is 340
You can check this answer by multiplying 340 by 1.25
If the answer is 425, then it is correct, else, not. [it is]

A wire that is 48 centimeters long is shown below.
The wire is cut into two pieces, and each piece is bent and formed into the shape of a square.
Answer:
The sides of the square measure 6 cm
Step-by-step explanation:
If we cut the wire in half, we have to:
48/2 = 24
We would have two 24 cm wires
With each wire a square will be formed, therefore the question I suppose must be how much each side of the square measures.
We know that the square has 4 equal sides, therefore:
4/24 = 6
The sides of the square measure 6 cm
The sides of the square measure 6 cm.
Calculation of the sides of squares:Since A wire that is 48 centimeters long
In the case when we cut the wire in half so it should be 50% of 48 i.e. 24
Also, the square does have 4 equal sides
So, the sides of the square should be
[tex]= 24\div 4[/tex]
= 6 cm
hence, The sides of the square measure 6 cm.
