Scale ratios are used to enlarge or compress a shape.
- <em>The scale factor is 13.</em>
- <em>The transformation rule is </em><em>.</em>
- <em>The mural will not distorted, because the sides are changed evenly.</em>
Given
To get the scale factor (k), we simply divide the final measurement by the scale measurement.
So, we have:
<u>For the length, we have:</u>
<u>For the width, we have:</u>
Hence, the scale factor is 13
<u>And the transformation is:</u>
This implies that, the muralist can apply for the transformation
Hence;
<em>(a) The mural will not distorted, because the sides are changed evenly.</em>

Answer:
Step-by-step explanation:
Let third cook take x hours to prepare the same number of pies y alone
Let y be the number of pies
In 1 hour ,third cook prepare pies=
One experienced cook takes time to prepare enough pies =4 hours
In 1 hour , cook prepare pies=
Another cook takes time to prepare same number of pies =7 hours
In 1 hour , another cook prepare pies=
All three cooks take time to prepare the same number of pies=2 hours
In 1 hour,all three cooks prepare pies=
According to question
hours
Hence, the third cook takes time to prepare the same number of pies alone=
Answer: If 2 log x + 3 log y = 0, find y in terms of x.

Answer:
See solution below
Step-by-step explanation:
The following are the rules for counter clockwise rotation of a point around the origin. Let's assume the coordinates of the original point are A(x, y). The following are results of different degrees of rotation(all counterclockwise) for the new point A'
<u>Original Point A</u> <u> Degree of Rotation</u> <u>Coordinates of A'</u>
A(x, y) 90° A'(-y, x)
A(x, y) 180° A'(-x, -y)
A(x, y) 270° A'(y, -x)
In these questions we are only interested in 270° counterclockwise rotation where the resultant point A' has its original x, y coordinates swapped and x is made negative. A, B represent the originals, A', B' etc the post image coordinates ie the answers
<u>Q1 </u>
A (4, 7) →→ A' (7, -4)
B (3, 0) →→ B' (0, -3)
C (-4, -7) →→ C' (-7, 4)
<u>Q3</u>
A (3, 0) →→ A' (0, -3)
B (7, 0) →→ B' (0, -7)
C (3, -5) →→ C' (-5, -3)
D (-2, -5) →→ D' (-5, 2)
