'Pi' is an irrational number. It can never be completely written with digits.

Here are the first 15 decimal places: 3.14159 26535 89792

A supercomputer lab in Japan has calculated 4 trillion digits of pi,
and it still doesn't end.

With higher mathematics, it's possible to prove that pi never ends.
So, no matter how many digits somebody gives you for pi, there are
still an infinite number more after those.

AXYZ has vertices at (0.0), (6,9), and (15.0).

exis [7]

Answer:

The coordinates of the vertices of the image are (0, 0), (2, 3), (5, 0) ⇒ (A)

Step-by-step explanation:

Let us talk about dilation

A dilation is a transformation that changes the size of a figure.
It can become larger or smaller, but the shape of the figure does not change.
The scale factor measures how much larger or smaller the image will be
If the scale factor greater than 1, then the image will be larger
If the scale factor between 0 and 1, then the image will be smaller

→ If point (x, y) dilated with scale factor m about the origin, then

→ Its image is (m x, m y)

Let us solve the question

∵ ΔXYZ has vertices:

→ X = (0, 0)

→ Y = (6, 9)

→ Z = (15, 0)

∵ ΔXYZ is dilated by a scale factor 1/3 about the origin

→ Multiply each coordinate in each vertex by the scale factor 1/3

∵ (0 × $\frac{1}{3}$ , 0 × $\frac{1}{3}$ )

∴ X' = (0, 0)

∵ (6 × $\frac{1}{3}$ , 9 × $\frac{1}{3}$ )

∴ Y' = (2 , 3)

∵ (15 × $\frac{1}{3}$ , 0 × $\frac{1}{3}$ )

∴ Z' = (5, 0)

∴ The coordinates of the vertices of the image are (0, 0), (2, 3), (5, 0)
