the composition of transformations that map ABCD to EHGF is a reflection over the y-axis followed by a translation by (4,7).
What is axis reflection ?
An axis reflection is a transformation in geometry that involves reflecting a point, a line, or an object across a given axis. In two dimensions, there are two axes of reflection: the x-axis and the y-axis.
When reflecting over the x-axis, all points stay in the same horizontal position but change their vertical position, so a point (x,y) is reflected to (x,-y).
When reflecting over the y-axis, all points stay in the same vertical position but change their horizontal position, so a point (x,y) is reflected to (-x,y).
Axis reflections can be used to transform geometric shapes such as polygons, circles, or lines. These transformations have important applications in various fields, including physics, engineering, computer graphics, and art.
To find the composition of transformations that map ABCD to EHGF, we first need to determine the individual transformations that are needed.
Reflecting over the y-axis will change the x-coordinates of the points, but leave the y-coordinates unchanged. So, to reflect over the y-axis, we negate the x-coordinates of the points.
The translation (x+4, y+7) will move each point 4 units to the right and 7 units up.
Therefore, the composition of transformations is:
Reflect over the y-axis by negating the x-coordinates:
A'(-2, 3), B'(-4, 2), C'(-4, 0), D'(-2, -1)
Translate by (4,7):
A''(2, 10), B''(0, 9), C''(0, 7), D''(2, 6)
Therefore, the composition of transformations that map ABCD to EHGF is a reflection over the y-axis followed by a translation by (4,7).

Find two numbers whose sum is 8 and whose product is 17
Answer:
Step-by-step explanation:
x+y = 8
y = 8-x
xy = 17
x(8-x) = 17
8x - x² = 17
x² - 8x + 17 = 0
Quadratic formula
x = [8 ± √(8² – 4·1·17)] / [2·1]
= [8 ± √(-4)] / 2
= [8 ± 2i] /2
= 4±i
x = 4+i
y = 4-i
A quadratic equation is written in the form of ax²+bx+c. The two numbers whose sum is 8 and whose product is 17 are (4+i) and (4-i).
What is a quadratic equation?A quadratic equation is an equation whose leading coefficient is of second degree also the equation has only one unknown while it has 3 unknown numbers. It is written in the form of ax²+bx+c.
Let the first number be 'a' and the second number be 'b'. Therefore, the sum of the two numbers is,
a+b=8
The product of the two numbers is,
ab=17
b=17/a
now, the equation can be written as,
a+b=8
a+(17/a)=8
a² + 17 = 8a
a²-8a+17=0
a = 4±i
Hence, the two numbers whose sum is 8 and whose product is 17 are (4+i) and (4-i).

The area of a square is 36 sq.cm, then its perimeter is a) 24 cm b) 6 cm c) 144 cm d) 36 cm
Answer:
Step-by-step explanation:
3.6*
It is very easy to find the perimeter of a square when its area is given in the question. For that, you only ned to know one fomula. That formula is: Area = side^2
For this particular question, the given value for the area of the square is 36 sq.cm. So, we can solve for the side(s) by substituting the given value in the above mentioned formula.
We get
36 = s^2
Now, we need to get the square root of both sides, which gives us
s = √36 s = 6 cm
Since all the sides of a square are equal in length, the side length is 6 cm. Now to determine the perimeter, we must multiply the side length by 4 (because there are 4 equal sides in a square). That gives us Perimeter = 4 x side length Perimeter = 4 x 6 cm.
Therefore, the perimeter of the square is 24 cm.

40 cm
45 cm,
35 cn
40 cm
The area of glass used to make the window is 3200 sq. cm.
What is a kite?A kite is a member of quadrilateral which has two diagonals. The area of a kite can be determined by;
area of a kite = (length of diagonal 1 * length of diagonal 2) / 2
Therefore to determine the square meter of glass used to make the window in the given question, we have;
length of diagonal 1 = 40 + 40
= 80 cm
length of diagonal 2 = 35 + 45
= 80 cm
area of the window = (80*80)/2
= 6400/2
area of the window = 3200 sq. cm.
Therefore, 3200 sq. m. of glass was used to make the window.

Define Mean?Average is another word for "mean." For instance, if we say that the average height of the 9th grade class is 150 cm, it signifies that this is the mean of all of the kids' heights.
The statistical notion of mean, which is employed in a variety of financial areas and corporate appraisal, has significant financial implications. The three statistical indicators of the central tendency of a data set are mean, median, and mode.
Now in the question, to find mean,
(5575 + 5617 + 3324 + 7860 + 494 + 3204 + 275 + 6899 + 578)/9

f(x) = ʃ Sqrt[9+X2 DX]
Thus, the derivative of the given function is found as: \(f'(x) = (2x) /\sqrt{(9 + x^{2} )}\).
Explain about the derivative of function:The derivative of a function f(x), also known as f'(x) or df/dx, is a measure of how quickly a function changes. A shift in the value of x is depicted in the image by the symbol x.
Hence, df/dx is a single phrase and should not be mistaken for a fraction. It is also a clue that x is the independent variable because it can be interpreted as the derivative of a function having respect to x.
Given function:
\(f(x ) = \sqrt{9 + x^{2} } .dx\)
Differentiating the function with respect to x, using the chain rule.
\(f'(x) = (9 + x^{2} )^{1/2 - 1} .(0 + 2x)\)
\(f'(x) = (9 + x^{2} )^{-1/2} .(2x)\)
\(f'(x) = (2x) /(9 + x^{2} )^{1/2}\)
\(f'(x) = (2x) /\sqrt{(9 + x^{2} )}\)

What else must you know to prove the triangles congruent by ASA? By SAS?
Note that given the proof of congruence by SAS, the only thing remaining to know is that "2 corresponding sides and the corresponding included angles of both triangles are equal."
What is the rationale for the above response?The definition of SAS Congruency is as follows:
The SAS postulate states that two sides and the included angle of one triangle are identical to the corresponding two sides and the included angle of another triangle.
As demonstrated in the triangle, the angles mCAD and mACB are congruent. Thus; m∠CAD ≅ m∠ACB
Because m∠CAD and m∠ACB are congruent, AD and BC must also be congruent. Now, because AC is shared by both triangles ABC and ADC, we get two matching equal sides with the included corresponding equal angles.
As a result, the SAS Congruence postulate is proven.
