Elena gives the following transformation to show that the two figures are similar by transforming ABCD into EFGD
Answers
It should be noted that the information regarding the transformation illustrates that Elena is wrong.
How to explain the information?A point, line, or geometric figure can be transformed in a way that affects the shape and/or location of the object. Pre-Image refers to the object's initial shape, and Image, after transformation, refers to the object's ultimate shape and location.
It should be noted that the first step makes the figures be the same by size but the second step, reflection over line AE doesn't map them together.
In this case, the correct line of reflection would be a vertical line through point D.
Therefore, it should be noted that the information regarding the transformation illustrates that Elena is wrong.

The correct answer is an option (A)
In this question, we have been given three numbers 4.5160 x 10^−3, 2.09 x 10^7, and 5.8 x 10^3
We need to find the number of significant digits of the product of above numbers.
First we find the product of given numbers.
4.5160 x 10^−3 × 2.09 x 10^7 × 5.8 x 10^3
= (4.5160 × 2.09 × 5.8) × (10^−3 × 10^7 × 10^3)

Write the equation in slope intercept form of the line that is parallel to the group in each equation and passes through the given point 7. y=-2x + 5; (3,-7)
Answers
Answer:
The equation in slope intercept form of the line that is parallel to the group in each equation and passes through the given point (3,-7) is y = -2/7x - 6.14
Step-by-step explanation:
It is given that the line that is parallel to the group in each equation and passes through the given point 7y= -2x + 5; (3,-7) and we need to write the equation in slope intercept form of the same line.
Now,
The slope of parallel lines is the same. By changing the equation to slope-intercept form, get the slope in the first line;
=> 7y= -2x + 5
=> y= -2/7x + 5/7
So, the slope = -2/7
Further,
Given the point and the knowledge that the second line would similarly have a slope of -2/7 and the point is (3, -7). With these numbers, we can construct an equation in the slope-intercept form and apply it to get the y-intercept;
=> y = mx + b
=> -7 = -2/7 × 3 + b
=> -7 + 2/7 × 3 = b
=> b = -6.14
Now, put the value of y-intercept back into the equation;
=> y = -2/7x - 6.14
Therefore, the equation in slope intercept form of the line that is parallel to the group in each equation and passes through the given point (3,-7) is y = -2/7x - 6.14

The transformations that maps Figure Y onto Figure Z are given by:
Dilation with a scale factor of 1/3.Reflection over the x-axis.Due to the dilation, Figures Y and Z are not congruent.What is a transformation in a function?A transformation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x).
Examples are shift left, shift right, shift down, shift up, vertical stretching, horizontal stretching, vertical compression, horizontal compression, reflection over the x-axis, reflection over the y-axis, and rotations by a determined amount(in degrees). All these translations have predetermined rules that we apply to the figures.
Another example of a transformation is a dilation, when the coordinates of the function are all multiplied by a constant, called scale factor. Due to the multiplication, after a dilation, the dilated figure is not congruent to the original figure, as they will have different side lengths.
For the dashed figure, we have that the coordinates of Y were all multiplied by 1/3, hence the first transformation is:
Dilation with a scale factor of 1/3.
Then for the dashed figure into Figure Z, the following rule is applied to each vertex:
(x,y) -> (x,-y).
Hence the second transformation is:
Reflection over the x-axis.
Due to the dilation, Figures Y and Z are not congruent.

Answer:
x = 4
Step-by-step explanation:
[tex] \sqrt{11x + 5} = 7 [/tex]
Square both sides. This step may introduce extraneous solutions, but we will deal with that after we find the solution.
[tex] (\sqrt{11x + 5})^2 = (7)^2 [/tex]
[tex] 11x + 5 = 49 [/tex]
Subtract 5 from both sides.
[tex] 11x = 44 [/tex]
Divide both sides by 11.
[tex] x = 4 [/tex]
Now we check for extraneous solutions. We substitute the value of the solution into the original equation, and we see if it makes the original equation true.
[tex] x = 4 [/tex]
[tex] \sqrt{11x + 5} = 7 [/tex]
[tex] \sqrt{11(4) + 5} = 7 [/tex]
[tex] \sqrt{44 + 5} = 7 [/tex]
[tex] \sqrt{49} = 7 [/tex]

500 = a^3
Take cube root of the volume to find the edge length
a = (500)^1/3
a = 7.93
a = 8 (approx.)
The length of the edge of the cube is a approximately 8.
So, The edge length of the cube is a approximately 8.
