what transformations were applied to ABCD to obtain A'B'C'D'?
Answer:
the answer is C
Step-by-step explanation:
Rotate 90 degrees counterclockwise , the translate three units to the left
Option C is the correct transformation to transform ABCD to A'B'C'D'.
What are rotation and translation?Rotation involves moving an object about a fixed point. Each point on the object describes a circular path with the center, the center of rotation.Translation involves moving an object such that only one of the three cartesian coordinates changes during the transformation.Rotation
Rotate the square ABCD counterclockwise about the origin. Sides AD and BC of square ABCD will become parallel to the sides A'D' and B'C' respectively of the square A'B'C'D'. The square ABCD is, thus, oriented the same way as the square A'B'C'D'.
Vertical Translation
After the rotation, the side AB is 1 unit above the y-axis, which is the same as that of the square A'B'C'D'. So, the vertical position of the square ABCD is the same as that of the square A'B'C'D'.
Horizontal Translation
The side AD of the square ABCD is 5 units to the left of the x-axis. The side A'D' of the square A'B'C'D' is 8 units to the left of the x-axis. So, translate the square ABCD to the left by 3 units to coincide with the position of A'B'C'D'.
Thus, to obtain A'B'C'D' from ABCD first rotate it by 90° counterclockwise then, translate it to the left by 3 units.

Mark a cross at (6,8)
Answer
Go 6 across to the right and 8 up from there
Step-by-step explanation:
Answer:
This is a coordinate, and it tells you where to plot a point on a set of axis. The first number in the coordinate tells you the x-value and the second one tells you the y-value. X-values go across the horizontal axis, known as the x-axis. Y-values go up and down the vertical axis, known as the y-axis.
In this case, to plot the point, you would start at the very center of the axis, where y and x both equal 0. You'd go 6 to the right, because they gave you a positive x-value. The you'd go up 8, because they gave you a positive y-value.
If they give you a negative x-value, you'd go to the left, and if they give you a negative y-value, you'd go down.
Hope that helped : )

[A] Set up a proportion that can be used to solve this problem.
[B] Show all steps to solve the problem.
HELP: Please and thank you!
Answer:
91.99%
Step-by-step explanation:
To find what percentage of $7599 is $6990, we simply need to divide $7599 by $6990 and multiply by 100:
6990 / 7599 * 100 = 91.99%
Therefore, they paid 91.99% of the original price.
What is the solution to the system of equations graphed below?
y = x+2 y=3x-2
Answer:
(2, 4)
x = 2
y = 4.
Step-by-step explanation:
To find the solution to the system of equations, we can simply set the two equations equal to each other as shown:
x + 2 = 3x - 2
Subtract 'x' from both sides:
2 = 2x - 2
Add '2' to both sides:
4 = 2x
x = 2.
Plug this value for 'x' into an equation to solve for 'y':
y = (2) + 2
y = 4.
Therefore, the solution to the system is (2, 4).
Answer:
Y=4
Step-by-step explanation:
How I did this.
y=x+2 y=3x-2
Moved around (you can do this)
y=2+2 y= 3x-x
y=4 y=2x
y=4.

Explain how to determine the zeros of f(x)=(x+3)(x-1)
Answer:
x= -3, x = 1
Step-by-step explanation:
Zeros are values of x, when f(x) = 0.
0=(x+3)(x-1)
x+3 = 0, x - 1=0
x= -3, x = 1
Answer:
x = -3, x = 1
Step-by-step explanation:
To determine the zeroes of the factored quadratic equation, we need to look back at its definition. The zeroes are a function are specific x-values that result in a y-value of 0.
In this case, we want the numbers inside of the parantheses to equal 0. If we substitute in x = -3, we get (0)(x - 1), and we know that is just 0. Similarly, if we substitute in x = 1, we get (x + 3)(0), and we know that is just 0.
As such, these are your solutions.

Answer:
60
Step-by-step explanation:
All angles = 180
All sides are equal
Therefore, 180/3 = angle degrees = 60
x is an opposite angle of bottom right angle therfore x = 60
Answer:
(a) x = 60°
(b) Angle x is alternate to the right base angle of the equilateral triangle.
Step-by-step explanation:
(a) The triangle in the figure above is an equilateral triangle in which all sides and angles are equal. The sum of angles in a triangle is 180°. Each angle in the equilateral triangle is 60° (180°/3 = 60°)
Therefore, angle x is 60°.
(b) Alternate angles are equal. Angle x and the right base angle of the equilateral triangle are alternate angles. Therefore, angle x is 60°.

A BOY IS FLYING A KITE, THE STRING IS 25M LONG AND IS AT AN ANGLE OF 42° WITH THE HORIZONTAL, USING A SCALE DIAGRAM, FIND HOW HIGH THE KITE IS ABOVE THE BOY’S HEAD?
Answer:
1. 35 km
2. 1 cm to 5m
3. 6 cm
4. [tex]42^\circ[/tex]
5. 16.73 m
Step-by-step explanation:
Solution 1.
Reading of map scale = 1cm:5km
i.e. 1 cm is equivalent to 5 km
Measurement of map = 7 cm
Actual distance = Measurement of map [tex]\times 5[/tex]
Actual distance = 7 [tex]\times 5[/tex] = 35 km
-------------------
Solution 2.
Length of dining hall = 35 m
Measurement of map = 7 cm
Scale = Measurement of map : Length of dining hall (i.e. ratio)
Scale = 7 cm :35 m = 1 cm : 5 m
-------------------
Solution 3.
Length of building = 30 m
Scale = 1 cm to 5m
5 m is equivalent to 1 cm on scale
1 m is equivalent to [tex]\frac{1}{5}[/tex] cm on scale
30m is equivalent to [tex]\frac{1}{5} \times 30[/tex] = 6 cm on scale
-------------------
Solution 4.
Angle of elevation of A from B = [tex]42^\circ[/tex]
Angle of depression of B from A = ?
Please refer to the image attached, we can clearly observe that both the angles (i.e. angle of elevation from A to B and angle of depression from B to A )will be equal.
Angle of depression of B from A = [tex]42^\circ[/tex]
-------------------
Solution 5.
Given that:
String length, or hypotenuse of triangle BC= 25 m
Angle of string with horizontal, [tex]\angle B = 42^\circ[/tex]
Please refer to the attached image for the clear understanding of the situation.
To find:
Height, AC = ?
We can use trigonometric identity:
[tex]sin\theta = \dfrac{Perpendicular}{Hypotenuse}[/tex]
OR
[tex]sinB = \dfrac{AC}{BC}\\\Rightarrow sin42^\circ = \dfrac{AC}{25}\\\Rightarrow AC = 25 \times 0.67\\\Rightarrow AC = 16.73 m[/tex]
============
So, the answers are:
1. 35 km
2. 1 cm to 5m
3. 6 cm
4. [tex]42^\circ[/tex]
5. 16.73 m
[tex] \frac{200}{l - 12} = \frac{300}{l - 9} [/tex]

The area of a rectangle is 20 square inches. If the length is 4 inches less than 6 times the width, then find the dimensions of the rectangle. Round off your answers to the nearest hundredth.
Answer:
dimensions are 2.19 inches by 9.14 inches
Step-by-step explanation:
Here, we are interested in knowing the dimensions of the rectangle
Now, let the width of the rectangle be x, from the question, we can write;
6x-4 as the length
Area of rectangle = l * b
x(6x-4) = 20
6x^2 - 4x = 20
divide through by 2
3x^2-2x = 10
3x^2 -2x -10 = 0
using quadratic formula;
x = -b ± √(b^2 - 4ac)/2a
From the quadratic equation, a = 3, b = -2 and c = -10
substituting these values, we have
x = 2 ± √(-2)^2 -4(3)(-10))/6
x = 2 ± √(124)/6
x = 2 + √(124)/6 or 2 - √(124)/6
x = (2+11.14)/6 or (2-11.14)/6
x = 2.19 or -1.52
Since width cannot be negative, we choose 2.19 alone
So the length is 6(2.19) -4 = 9.14

Answer:
A) inside the circle
Step-by-step explanation:
equation of the circle is:
[tex](x-a)^{2} + (y-b)^{2} = r^{2}[/tex]
where (a,b) is center of the circle and r is radius so
[tex]x^{2} + y^{2} = r^{2}[/tex] now plug in given point to find the radius
[tex](6)^{2} + (-4)^{2} = r^{2}[/tex]
36 +16 = 52 so
r = [tex]\sqrt{52}[/tex] ≈ 7.2 or [tex]r^{2} =52[/tex]
when you plug point (√2 , -7) into equation of the circle
(√2)^2 + (-7)^2 = 2 +49 =51
51 is less than 52 so this is inside of the circle

Answer:
1). a = 9.42 m
2). b = 6.37 m
3). c = 4.48 m
Step-by-step explanation:
In the figure attached,
By applying tangent rule in triangle ADE,
tan47 = [tex]\frac{h}{c}[/tex]
c = [tex]\frac{h}{\text{tan}47}[/tex]
c = [tex]\frac{4.8}{\text{tan}47}[/tex]
c = 4.476
c ≈ 4.48 m
Now we apply the same rule in triangle ACE,
tan37° = [tex]\frac{h}{b}[/tex]
b = [tex]\frac{h}{\text{tan}37}[/tex]
b = [tex]\frac{4.8}{1.0724}[/tex]
b = 6.37 m
Now apply the tangent in triangle ABE,
tan27° = [tex]\frac{h}{a}[/tex]
a = [tex]\frac{h}{\text{tan}27}[/tex]
a = [tex]\frac{4.8}{0.5095}[/tex]
a = 9.42 m
