This diagram shows a pre-image △ABC, and its image, △A′′B′′C′′, after a series of transformations. Select from the drop-down menus to correctly complete the statements. △ABC is Choose... to become △A′B′C′. Then △A′B′C′ is Choose... to become △A′′B′′C′′ . Because the transformations are Choose... , the pre-image and image are Choose... . Triangles on a coordinate plane whose axes are labeled x and y. Triangle A B C has vertex A at 1 comma negative 1, vertex B at 4 comma negative 2, and vertex C at 7 comma 2. Triangle A prime B prime C prime has vertex A prime at negative 1 comma 1, vertex B prime at negative 4 comma 2, and vertex C prime at negative 7 comma negative 2. Triangle A double prime B double prime and C double prime has vertex A double prime at negative 1 comma negative 2, vertex B double prime at negative 4 comma negative 1, and vertex C double prime at negative 7 comma negative 5.
The answers that complete the statements of the series of transformations are;
- △ABC to △A′B′C′; because the △ABC has been rotated at angle of 180° about the origin.
- △A′B′C′ to △A′′B′′C′′; Because the △A′B′C′ has been shifted down by 3 units.
- All 3 transformations are rigid transformations
- All three transformations are congruent transformations.
The image showing triangles △ABC, △A′′B′′C′′, and △A′B′C′ is missing and so I have attached it.From the image attached, we see the following coordinates of the triangles;
Coordinates of △ABC; A(1, -1), B(4, -2), C(7, 2)
Coordinates of △A′B′C′; A'(-1, 1), B'(-4, 2), C'(-7, -2)
Coordinates of △A′′B′′C′′; A''(-1. -2), B''(-4, -1), C''(-7, -5)
Now, in transformation from △ABC to △A′B′C′, we see that the pattern of transformation is; (x, y) → (−x ,−y). This pattern where coordinates of x and y are transformed to the negative part of them denotes that there has been a rotation at angle of 180° about the origin.In transformation from △A′B′C′ to △A′′B′′C′′, we see that triangle shifted down because the y-coordinates have reduced by 3 units. Thus, we can say that the transformation was to shift △A′B′C′ down by 3 units.In each of the transformations, we can tell that regardless of the position of the triangle, the distances AB, BC and AC remain the same. Thus, the transformation is rigid. The transformations are also congruent because all their corresponding sides are equal.Read more at; https://brainly.com/question/11254677

Answer:
The inequality is x/5 < 20, and 100 is in the box.
Step-by-step explanation:
x = the amount she spends in June.
So, since she spends an equal amount five times, the amount she spends each time is x/5.
She wants this to be less than 20.
So, x/5 < 20.
Solving for x by multiplying both sides of the equation by yields
x < 5 * 20
x < 100, so that 100 goes into the box.

Answer:
[tex]4 {x}^{3} + 2 {x}^{2} - 8x - 4[/tex]
Step-by-step explanation:
it's simple, just multiply
f.g(x)=(x^2-2)(4x+2)=4x^3+2x^2-8x-4
Step-by-step explanation:
Hi there!
f(x) = x²-2
g(x) = 4x+2
Then;
f(x).g(x) = (x²-2)*(4x+2)
= x²(4x+2) -2 (4x+2)
= 4x³ + 2x² - 8x - 4
Therefore, the answer is f(x).g(x)= 4x³ + 2x² - 8x - 4.

quick brainliest asap!! sin^-1 (1.1976) SHOW YOUR WORK so I can see if it makes sense!!
Answer:
no solutions
Step-by-step explanation:
We want to find [tex]\theta[/tex] such that [tex]\theta=\sin^{-1}(1.1976)[/tex].
We can take the sine of both sides of the equation to get[tex]\sin(theta)=\sin(\sin^{-1}(1.1976))=1.1976[/tex].
We know that the range of the sine function goes from -1 to 1 inclusive, so there is no value [tex]\theta[/tex] such that [tex]\sin{\theta}>1[/tex].
Therefore, the answer is [tex]\boxed{no~solutions}[/tex] and we're done!

A cloud drifted above an airplane that was flying at 5,300 meters per minute. In 22.5minutes, the cloud moved 7,920meters to the east at a constant velocity. What was the cloud's velocity?
Answer is 352 metres
Step-by-step explanation:-The cloud is moving at a constant velocity. This means that we can find the velocity of the cloud by dividing the distance it moved by time:-
[tex]v = \frac{d}{t} [/tex]
Where "v" is velocity, "d" is distance and "t" is time.
The cloud moved 7920 metres in 22.5 minutes, so :-
[tex]v = \frac{7920 \: m}{22.5 \: min} [/tex]
[tex]v = 352 \: m/min[/tex]
Therefore, the cloud's velocity was 352 m/min.

Find the equation of the line through the point ( 3 , − 7 ) that is perpendicular to the line with equation y = x − 12 .
Answer: y = -x - 4
Step-by-step explanation:
A perpendicular line has a slope that is the negative inverse of the reference line, which is y = x-12. The slope here is 1, so the negative inverse would be -1/1, or -1. The perpendicular line would therefore be:
y = -1x + b
We can find b by using the given point (3,-7) as a solution:
y = -1x + b
-7 = -1*3 + b
b = - 4
The equation is therefore y = -x - 4

Answer:
1) Divide the numerator by the denominator to get 0.6
2) Divide the numerator by the denominator to get 0.7
3) Divide the numerator by the denominator to get 0.25
4) Place 55 over 100, since this number is in the hundredths place, and then divide it (55 ÷ 100). Your answer is 11/20 .
5) Place 6 over 10, since this number is in the tenths place, and then divide it
(6 ÷ 10 = 3/5). Next multiply the whole number (10) by the denominator (5) and then add the numerator (3) to get 53. You now have 53/5 which is the improper form, or 10 3/5 which is the mixed number form.
6) Place 856 over 1,000 , since this is in the thousandths place, and then divide it
(856 ÷ 1,000). Your answer is 107/125 .

What is an equation of the line that passes through the point ( − 3 , − 1 ) and is perpendicular to the line x − 2 y =6
Answer: y = -2x - 7
Step-by-step explanation:
The equation for a perpenducular line has a slope that is the negative inverse of the reference line, in this case x - 2y = 6.
Let's put this equation into standard slope-intercept form, y = mx+b, where m is the slope and b the y-intercept (the value of y when x is 0).
x - 2y = 6
- 2y = 6 - x
y = (1/2) x -3
The slope is (1/2), so a perpendicular line will have a slope of -2.
y = -2x + b
We can find b by using the given point ((-3,-1), a known solution):
-1 = -2*(-3) + b
-1 = 6 + b
b = -7
The perpendicular equation is y = -2x - 7
y = -2x

What are the three trigonometric reciprocals of sine, cosine, and tangent?
Answer:
Secant, cosecant and cotangent.
Step-by-step explanation:
Step-by-step explanation:
There are three reciprocal trigonometric functions, making a total of six including cosine, sine, and tangent. The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). The reciprocal tangent function is cotangent, expressed two ways: cot(theta)=1/tan(theta) or cot(theta)=cos(theta)/sin(theta).
A polynomial function has a root of –6 with multiplicity 1, a root of –2 with multiplicity 3, a root of 0 with multiplicity 2, and a root of 4 with multiplicity 3. If the function has a positive leading coefficient and is of odd degree, which statement about the graph is true?
The graph of the function is positive on (–6, –2).
The graph of the function is negative on (negative infinity, 0).
The graph of the function is positive on (–2, 4).
The graph of the function is negative on (4, infinity).
Answer:
A. The graph of the function is positive on (–6, –2)Step-by-step explanation:
The given function is an increasing function that intercepts the x- axis at -6, -2 and 4 and touches at 0.
It has minimum at negative infinity, maximum at positive infinity, local minimums between -2 and 0 and between 0 and 4, local maximum between -6 and -2.
