Which transformations can be used to map a triangle with vertices A(2, 2), B(4, 1), C(4, 5) to A’(–2, –2), B’(–1, –4), C’(–5, –4)? a 180degree rotation about the origin a 90degree counterclockwise rotation about the origin and a translation down 4 units a 90degree clockwise rotation about the origin and a reflection over the y-axis a reflection over the y-axis and then a 90degree clockwise rotation about the origin
Answers
The transformations that can be used to map a triangle with vertices A(2, 2), B(4, 1), C(4, 5) to A’(–2, –2), B’(–1, –4), C’(–5, –4) is C. a 90 clockwise rotation about the origin and a reflection over the y-axis
What is a Transformation?This refers to the mathematical process where one figure or expression is changed from one form to another that has or contains a similar value.
Given the pair of points (x, y) in the original image, it has been transformed to (-y, -x).
If we allow ABC to be first transformed onto A"B"C" by a 90° clockwise rotation, this would result in:
B(4, 1) being mapped onto B''(1, -4).
Therefore, the rule mapping ABC to A"B"C" is (x, y)→(y, -x)
With this, we can conclude that the transformation that maps (y, -x) to (-y, -x) is a reflection with respect to the y-axis
Option C is the correct transformation.

A. When the team scored 52 points, the median number decreased.
Step-by-step explanation:
The median now is 88. Without the 52, (using the median formula,) it would become 88.5. Since 88.5 is larger than 88, it means the median decreased after 52 was added. There was no change when 91 was added.

What is the Sine Rule?The Law of Sines (also called the Sine Rule) is defined as it relates all three sides of a triangle with an angle of a triangle.
Triangle is a basic polygonal shape of a triangle that has three sides and three interior angles. It is one of the fundamental shapes in geometry.
As per the given question, the given data as:
A = 63
B = 56
C = 61 (because these angles should add up to 180)
c = 1/2
We know that the Sine Rule,
sin 63 / a = sin 61 / .5
a = 0.51 miles
sin 56 / b = sin 61 / .5
b = 0.47 miles
Therefore, the length 0.51 miles and 0.47 miles are the distances from each observer to the sailboat.

A triangle prism has a volume of 240m3.The area of the base is 16m2 what's is the height of the triangle prism
Answers
Answer:
The height is 45 m
Step-by-step explanation:
The volume of a triangular prism is V = (1/3)(area of base)(height)
If the voume is 240 m^3 and the area of the base 16 m^2, then the height of the prism is determined as follows:
3V = (area of base)(height)
Dividing both sides by (area of the base), we get:
3(240m^3)
height = ------------------------- = 45 m
16 m^2

A parabola has focus (5,1) and directrix y=-3.
Where is the parabola’s vertex?
Answers
Answer:
vertex = (5, - 1 )
Step-by-step explanation:
The focus and directrix are equidistant from the vertex
Since the equation of directrix is y = - 3 then the parabola is vertical,
The distance between the focus and directrix is
| 1 - (- 3) | = | 4 | = 2
Thus the vertex is 2 units below the focus
vertex = (5, 1 - 2 ) = (5, - 1 )
A parabola has focus (5, 1) then the vertex of the parabola will be (5, -1).
What is a Parabola?A location on the curve that is equally spaced from both a fixed location and a fixed line is referred to as a parabola. The parabola's focus requires and fixed line are referred to as its foci and directrix, respectively.
As per the given information in the question,
The focus and directrix are equidistant from the vertex then,
The parabola is vertical because the directrix's equation is y = - 3; hence, the focus and directrix are separated by:
|1 - (-3)| = |4| = 2
The vertex is therefore 2 units below the focus.
vertex = (5, 1 - 2) = (5, -1)
