<h3>Answer:</h3>

F (3x, 3y)

<h3>Explanation:</h3>

Dilation about the origin multiplies each coordinate by the dilation factor. For some coordinates (x, y), dilation by a factor of 3 means the new coordinates are ...

... 3×(x, y) = (3x, 3y)

_____

<em>Comment on the problem</em>

The way the problem is worded, you expect an answer choice that will be specific to the coordinates of point A. There are none.

Instead, the answer choices are generic, corresponding to dilation of a point (x, y) by a factor of 3, translation up and to the right by 3, dilation by a factor of 1/3, and translation down and to the left by 3.

Anuta_ua [19.1K]

Answer:

Hexagon AGHBGHCGHDGHEGHFGH coincides with hexagon ABCDEF when GH passes through the midpoints of opposite sides; that is, it is a perpendicular bisector of the two sides. HexagonAGHBGHCGHDGHEGHFGH also coincides with hexagon ABCDEF when the line of reflection joins a pair of vertices opposite one another on the hexagon. There are three perpendicular bisectors and three pairs of opposite vertices. In all, there are six lines of reflection that will map the hexagon back onto itself.

Write an algebraic expression to answer each question do this on a sheet of paper
Korolek [52]

Hello.

In 10 years, his age will be

\mathrm{z+10}

The sum of his current age and 10 equals his age in 10 years.

2 years ago his age was

\mathrm{z-2}

The difference of his current age and 2 equals his age 2 years ago.

7 years ago his age was

\mathrm{z-7}

The difference of his current age and 7 equals his age 7 years ago.

Therefore, his age after 10 years will be \mathrm{z+10}, his age 2 years ago was \mathrm{z-2}, and his age 7 years ago was \mathrm{z-7}

I hope it helps.

Have a nice day.

The numbers of teams remaining in each round of a single-elimination tennis tournament represent a geometric sequence where an i
Anit [1.1K]

Answer:

a_n = 128\bigg(\dfrac{1}{2}\bigg)^{n-1}

Step-by-step explanation:

We are given the following in the question:

The numbers of teams remaining in each round follows a geometric sequence.

Let a be the first the of the geometric sequence and r be the common ration.

The n^{th} term of geometric sequence is given by:

a_n = ar^{n-1}

a_4 = 16 = ar^3\\a_6 = 4 = ar^5

Dividing the two equations, we get,

\dfrac{16}{4} = \dfrac{ar^3}{ar^5}\\\\4}=\dfrac{1}{r^2}\\\\\Rightarrow r^2 = \dfrac{1}{4}\\\Rightarrow r = \dfrac{1}{2}

the first term can be calculated as:

16=a(\dfrac{1}{2})^3\\\\a = 16\times 6\\a = 128

Thus, the required geometric sequence is

a_n = 128\bigg(\dfrac{1}{2}\bigg)^{n-1}
