In quadrilateral ABCD, A = (0, 0), B = (3, 2), C = (4, −2), and D = (3, −3). Describe the image of ABCD under the translation T<−4, 2> by dragging and dropping the vertices of ABCD to the corresponding vertices of T<−4, 2>(ABCD).
Answer:
In quadrilateral ABCD, A = (0, 0), B = (3, 2), C = (4, −2), and D = (3, −3). Describe the image of ABCD under the translation T<−4, 2> by dragging and dropping the vertices of ABCD to the corresponding vertices of T<−4, 2>(ABCD).
Step-by-step explanation:
The image of ABCD is formed by points [tex]A'(x,y) = (-4, 2)[/tex], [tex]B'(x,y) = (-1, 4)[/tex], [tex]C'(x,y) = (0, 0)[/tex] and [tex]D'(x,y) = (-1, -1)[/tex].
Vectorially speaking, a translation is defined by the following formula:
[tex]P'(x,y) = P(x,y) + T(x,y)[/tex] (1)
Where:
[tex]P(x,y)[/tex] - Original point.[tex]T(x,y)[/tex] - Translation vector.[tex]P'(x,y)[/tex] - Resulting point.If we know that [tex]A(x,y) = (0,0)[/tex], [tex]B(x,y) = (3, 2)[/tex], [tex]C(x,y) = (4, -2)[/tex], [tex]D(x,y) = (3, -3)[/tex] and [tex]T(x,y) = (-4,2)[/tex], then the resulting points of the rectangle are:
[tex]A'(x,y) = (0, 0) + (-4, 2)[/tex]
[tex]A'(x,y) = (-4, 2)[/tex]
[tex]B'(x,y) = (3, 2) + (-4,2)[/tex]
[tex]B'(x,y) = (-1, 4)[/tex]
[tex]C'(x,y) = (4,-2) + (-4, 2)[/tex]
[tex]C'(x,y) = (0, 0)[/tex]
[tex]D'(x,y) = (3, -3) + (-4, 2)[/tex]
[tex]D'(x,y) = (-1, -1)[/tex]
The image of ABCD is formed by points [tex]A'(x,y) = (-4, 2)[/tex], [tex]B'(x,y) = (-1, 4)[/tex], [tex]C'(x,y) = (0, 0)[/tex] and [tex]D'(x,y) = (-1, -1)[/tex].

HELP Explain the Triangle Inequality Theorem as it relates to angles.
Answer:
If two sides of a triangle are unequal, then the measures of the angles opposite these sides are unequal, and the greater angle is opposite the greater side.
have a great day and easter
The Inequality Theorem states that, If two angles of a triangle are unequal, then the measures of the sides opposite these angles are also unequal, and the longer side is opposite the greater angle.
What are triangles?A triangle is a polygon with three edges and three vertices.
Triangle Inequality Theorem :-
If two angles of a triangle are unequal, then the measures of the sides opposite these angles are also unequal, and the longer side is opposite the greater angle.
For example :-
Consider a triangle RQS,
List the sides of this triangle in increasing order.
Because 30° < 50° < 100°, then RS < QR < QS.

which best describes this equation
10+6 x=15+9 x-3 x
a one real solution
b the solution is 0
c no real solutions
d an infinite number of solutions
Answer:
c. no real solutions
Step-by-step explanation:
because:
1. 10+6x=15+9x-3x
6x+10=15+9x-3x
2. 6x+10=15+9x-3x
6x+10=15+6x
3. 6x+10=15+6x
6x+10=6x+15
4. 6x+10=6x+15
6x+10-10=6x+15-10
5. 6x=6x+5
6. 6x=6x+5
6x-6x=6x+5-6x
Then you get:
0=5
remember, If you want to know if an equation has no equation:
the constants are the numbers alone with no variables. If the coefficients are the same on both sides then the sides will not equal, therefore no solutions will occur. Use distributive property on the right side first.

a cyclist rides his bike at a rate of 5 kilometers per hour.what is this rate in
miles per hour? how many miles will the cyclist travel in 5 hours? in your
computations assume that 1 mile is equal to 1.6 kiolmeters. Do not round your
answers
Answer:
rate is 8 miles per hour and he travels 40 miles per 5 hours
Step-by-step explanation:
The story problem told that i should assume that 1 mile is 1.6 km
so 5km/hr is equal to 8m/h
i got it by multiplying 5 by 1.6 so i can change from the unit km to mile
so about the miles per 5 hours just multiply the 8 mph by 5 so it is 40
40miles per 5hrs
hope i made it clear

In ΔKLM, l = 26 cm, k = 56 cm and ∠K=22°. Find all possible values of ∠L, to the nearest degree.
Answer:
10 degrees
Step-by-step explanation:
sdfsdfs
The possible value of ∠L in ΔKLM is approximately 22 degrees.
What is geometry?Geometry is the study of two-dimensional and three-dimensional figures such as quadrilaterals, triangles, circles, their sides, and angles.
A square triangle is a diagram made by using the squares and the triangle simultaneously. Here in the image below you can see we can make the square triangle by using one square and three triangles.
To find the possible values of ∠L in triangle ΔKLM, we can use the Law of Cosines, which relates the sides and angles of a triangle:
c² = a²+ b²- 2abcos(C)
Where a, b, and c are the lengths of the sides of the triangle opposite to the angles A, B, and C, respectively.
In our case, we know that:
KL = l = 26 cm (the side opposite to ∠M)
KM = k = 56 cm (the side opposite to ∠L)
∠K = 22° (angle opposite to KL)
To find the length of LM (the side opposite to ∠K), we can use the Law of Cosines:
LM² = KL² + KM^2 - 2KLKMcos(K)
LM² = 26² + 56² - 2(26)(56)cos(22°)
LM ≈ 61.3 cm
Now we can use the Law of Sines, which relates the lengths of the sides and the opposite angles of a triangle:
a/sin(A) = b/sin(B) = c/sin(C)
In our case, we can use this formula to find the value of sin(∠L):
sin(∠L)/KM = sin(∠K)/LM
sin(∠L)/56 = sin(22°)/61.3
sin(∠L) ≈ 0.374
∠L ≈ arcsin(0.374)
∠L ≈ 22° (rounded to the nearest degree)
Therefore, the possible value of ∠L in ΔKLM is approximately 22 degrees.

Madeline needs to find the slope of the line that passes through the points (9, 12) and (7,4) she sets up the following work
Answer:

The slope of the line passing through two given points: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
(9, 12) ⇒ x₁ = 9, y₁ = 12
(7, 4) ⇒ x₂ = 7, y₂ = 4

A rectangular table is 64 inches long and 35 inches wide. What is the perimeter of this table
The perimeter of a rectangular table is 198 inches.
What is the perimeter of a rectangle?The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).
Given that, a rectangular table is 64 inches long and 35 inches wide.
Now the perimeter of table is
2(64+35)
= 2×99
= 198 inches
Therefore, the perimeter of a rectangular table is 198 inches.
