A translation of T(x, y) = (- 5, 2) and a dilation with center (- 5, 2) with a scale factor of 1 / 3 are necessary to transform circle A into circle B. (Correct choice: D)
<h3>What sequence of rigid transformations can be done on a circle</h3>
In this problem we must determine the sequence of transformations require to transform circle A into circle B. From analytical geometry we know that the equation of the circle in standard form is:
(x - h)² + (y - k)² = r²
Where:
- (h, k) - Coordinates of the center.
- r - Radius of the circle.
Then, we need to apply the following rigid transformations:
Translation
f(x, y) → f(x - h, y - k), where (h, k) is the translation vector.
Dilation with center at the center of the circle
r → k · r, where k is the scale factor.
The circle A is represented by x² + y² = 3, then we derive the expression for the circle B:
f(x, y) → f(x + 5, y - 2)
(x + 5)² + (y - 2)² = 9
r → k · r
(x + 5)² + (y - 2)² = (1 / 3)² · 9
(x + 5)² + (y - 2)² = 1
Then, a translation of T(x, y) = (- 5, 2) and a dilation with center (- 5, 2) are necessary to transform circle A into circle B.

Well if you have 60 and she has 120 i will set it out as a sequence week by week

it would take 31 weeks and the total is 270
Answer:
32 pizzas
60 pizzas
1/24
Step-by-step explanation:
Se hicieron 8 docenas de pizzas.
Una docena es 12, por lo tanto, el número de pizzas hechas fue:
8 * 12 = 96 pizzas
1/3 se vendieron en el local, esto significa que el número de pizzas vendidas en el local es:
1/3 * 96 = 32 pizzas
5/8 fueron para entrega a domicilio, por lo tanto, el número de pizzas vendidas en casa es:
5/8 * 96 = 60 pizzas
El número total de pizzas vendidas es:
32 + 60 = 92 pizzas
Esto significa que no se vendieron 4 pizzas. En forma de fracción:
4/96 = 1/24
0.00100037227 will be your correct answer.
