1. dilation factor: 1/2
2. rotation: about origin anti-clockwise 180°
Δ ABC - Δ A'B'C', because AA'B'C' is obtained by dilating AABC by a scale factor of 1/2 and then rotating it about the origin by 180 degrees.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
We have to find the statement which is correct for triangle ABC and triangle A'B'C'.
Let us find the coordinates of triangle ABC
A=(2, 2), B=(2, 10) and C=(8, 12)
After transformation the triangle A'B'C'.
Coordinates A' = (-1, -1), B(-1, 5) and C'(-4, 6)
The scale factor is 1/2.
A dilation is a transformation which preserves the shape and orientation of the figure, but changes its size.
Δ ABC - Δ A'B'C', because AA'B'C' is obtained by dilating AABC by a scale factor of and then rotating it about the origin by 180 degrees.
Hence, Δ ABC - Δ A'B'C', because AA'B'C' is obtained by dilating AABC by a scale factor of 1/2 and then rotating it about the origin by 180 degrees.

65
which one is the answer
Answer:
65
Step-by-step explanation:
f(x) = 2x² + 4
g(x) = x - 6
f(-5) = 2 * (-5)² + 4
= 50 + 4
= 54
g(-5) = - 5 - 6
= - 11
f(-5) - g(-5) = 54 + 11 = 65

i think so i'm not sure if it is correct
Answer:
C.) 78.5
Step-by-step explanation:
c = pi x r²
c = 3.14 x (5)²
c = 3.14 x 25
c = 78.54
c ≈ 78.5 (round to the nearest tenth) (4 is less that 5, so we round down to 5)

What is trigonometric ratio?In trigonometry, there are six trigonometric ratios, namely, sine, cosine, tangent, secant, cosecant, and cotangent.
sin θ = Perpendicular/Hypotenuse
cos θ = Base/Hypotenuse
tan θ = Perpendicular/Base
sec θ = Hypotenuse/Base
cosec θ = Hypotenuse/Perpendicular
cot θ = Base/Perpendicular
Given in the figure,
ABC is right angle triangle
∠BAD = 90°
∠ABD = ?
AB = 125 ft
AD = 140 ft

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To calculate the commission earned by each salesperson, we need to multiply the rate of commission by the total sales amount.
The total sales amount is the product of the number of items sold and the cost of each item.
For Felix:
Commission = (Rate of commission) x (Total sales amount)
= 7.25% x (9 x $60)
= $39.15
For Helen:
Commission = (Rate of commission) x (Total sales amount)
= 7.50% x (12 x $50)
= $45.00
For Reid:
Commission = (Rate of commission) x (Total sales amount)
= 8.25% x (10 x $40)
= $33.00
For Sidney:
Commission = (Rate of commission) x (Total sales amount)
= 7.75% x (6 x $90)
= $39.15
Therefore,
Both Felix and Sidney earned the same amount of commission, which is $39.15.
Helen earned the most commission, which is $45.00.

Draw a line through the point (2, 0) with a slope of 1/4
Answer:
y = 1/4 x - 1/2
Step-by-step explanation:
Remark
The general equation for a line is y = mx + b
You know that m = 1/4. The problem is what do you do about (2,0)?
Solution
y = 1/4 x + b Let x = 2 when y = 0
0 = 1/4 * 2 + b multiply 2 * 1/4
0 = 1/2 + b Subtract 1/2 from both sides
b = - 1/2

A curve with a horizontal asymptote and either an increasing slope or a decreasing slope called an exponential graph. i.e., it begins as a horizontal line, increases or drops gradually, and then the growth or decay accelerates.
Given the graph of function,
The graph of any exponential function is parallel to an axis and drop and increase show the decay or growth,
since the equation,

has a negative sign the graph will go down,
y-intercept for the graph is 3,

Any languages have what some consider a significant limitation: they lack a gender-neutral third-person singular pronoun. When using a pronoun to refer to a person, speakers must either specify a gender or say something like "he or she." Not only can this be cumbersome, but it means that there is no good pronoun choice when a person's gender is unknown to the speaker. Sweden addressed this problem in 2015 by adding a new pronoun—hen—which refers to a person without specifying a male or female gender. Hen does not replace the Swedish pronouns han, meaning "he," or hon, meaning "she"; it simply adds another option. Thus, Swedes now have their choice of three,

The height (one of the legs) and the hypotenuse of an isosceles right triangle are 40 feet and 40√2 feet, respectively.
What is Pythagoras theorem?In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.
Given:
The triangle is an isosceles right triangle.
That means, the triangle has two equal sides.
Let, base b = height h.
The area of the triangle = 1/2 x base x height.
800 = (1/2)b²
b² = 1600
b = 40 feet.
Now, using the Pythagoras theorem,
Hypotenuse = √(1600 + 1600)
Hypotenuse = √(3200)
Hypotenuse = 40√2 feet.
Therefore, height = 40 feet and hypotenuse = 40√2 feet.

To find the diameter of a circle when you have a circumference, all you need to do is divide the circumference by pi. (So 106.76 ÷ π)
So:
106.76 ÷ π = 33.98276344.... (irrational number)
