Tom and Sophie travel from home to school and back once a day. How many kilometres more does Sophie travel in 5days than Tom?

exis [7]

Answer:

1000 m

Step-by-step explanation:

Tom's distance = 400 m

Sophie's distance = 600 m

Hence. Distance per day = 600 - 400 = 200 m per days

In 5 days ;

200 m * 5 = 1000 m

Sophie travels 1000 m more

Part A:

An isometric transformation is a type of transformation where the original shape and size of the pre-image is not altered in the image.

To show that the translation was an isometric transformation, we show that the distance between any two points in the pre-image is equal to the distance between the corresponding points in the image.

Consuder, line AB, the distance between point A and point B is given by:

$d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\ \\ = \sqrt{(-1-(-6))^2+(0-0)^2} = \sqrt{(-1+6)^2+0^2} \\ \\ = \sqrt{5^2+0} = \sqrt{25} =5$

The distance between point A' and point B' in the image is given by:

$d= \sqrt{(3-(-2))^2+(4-4)^2} \\ \\ = \sqrt{(3+2)^2+0^2} = \sqrt{5^2+0} \\ \\ = \sqrt{25} =5$

Similarly checking other points of the pre-image against the corresponding points of the image shows that the size of the pre-image is preserved in the image.

Part 2:

The translation that maps the triangle ABC onto its image are:
Triangle ABC was shifted 4 units to the right.
Triangle ABC was shifted 4 units up.
