Answer:

Image IV

Step-by-step explanation:

We are given that

Heart 1 is translated 3 units down to heart 2.

We have to find the image which shows this transformation.

The translation rule when a figure is shift 3 units down is given by

$(x,y)\rightarrow (x,y-3)$

The coordinates of a point lie on heart are (-2.5,3)

After translation 3 units, the coordinates of corresponding point which lie on the heart

$(-2.5,3)\rightarrow (-2.5,0)$

Therefore,the heart shift from II quadrant to III quadrant.

Image I is not true because the heart 1 shift to heart 2 in quadrant III not in IV quadrant.

In image II ,the corresponding point of the point (-2.5,3) is (-2.5,-3).

Image II is not true because the corresponding point is (-2.5 ,0) not (-2.5,-3).

Image III is not true because heart 2 should be in quadrant III not in quadrant I after translation 3 units down of heart 1.

Image IV is true because the corresponding point of the point (-2,5,3) is (-2.5,0) and heart 2 lies in quadrant III.

A triangle is dilated by a scale factor of 1/5 and then rotated 90 degree clockwise about the origin. Why is the image similar t

yan [13]

Answers:
The corresponding angles of the triangles are congruent
The image is a reduction of the pre-image
Neither the dilation nor the rotation change the shape of the triangle

Explanation:
For shapes to be similar:
1- there should be a ratio between the sides
2- angles in first shape should be congruent to angles in second shape

Now, a scale factor of 0.2 means that the sides of the image are 0.2 of the length of the original shape. However, angles are not changes

Let's check the choices:
1- The corresponding sides of the triangles are congruent:
This option is incorrect as dilation changes the lengths of the sides

2- The corresponding angles of the triangles are congruent:
This option is correct as neither dilation nor rotation alters the measures of the angles

3- The corresponding sides of the image are 5 times as long as those of the pre-image:
This option is incorrect as the sides of the image are only 0.2 times as long as those of the pre-image

4- The image is a reduction of the pre-image:
This option is correct as the sides of the image are 0.2 times those of the pre-image which means that the shape is reduced

5- Neither the dilation nor the rotation change the shape of the triangle:
This option is correct as both dilation and rotation are rigid transformations that do not alter the shape of the triangle (a triangle remains a triangle only with different side lengths)

6- The rotation reduces the size of the triangle:
This option is incorrect as rotation does not alter the size of the shape. It only changes its position

Hope this helps :)

Twelve more than half of a number is equal to the number

tester [92]

Let's consider that number to be 'x'..
So, twice the number (2x) is 12 greater than than the half of the number.
So the equation will be like,
2x=12+x/2
Solving this further,
2x=(24+x)/2
=> 4x=24+x
=>4x-x=24
=>3x=24
=>x=8..
So the number is "8".

Daniel is currently 26 years older than his son. In sic years he will be tree times older than his son. How old are both of them

Vlad1618 [11]

well, 26+6 is 32, so divide that by 3 and you'd get 10.67, making daniel 32 by that time and his son being 10 years old

its simple math really, also, i hope this helps you ^-^
