Answer: 1,2,3, and 5
Step-by-step explanation:
The isometries that preserve a shapes angles and line segments making the pre image congruent to the (post) image are :
Reflections, rotations, translations
These are rigid transformations. Think of your ruler. If you flip it, slide it, or rotate it around, did the ruler change shape? No. Just positions.
If you dilate something, you are either making it larger or smaller, therefore changing the size of the shape.
Anything that has dilation in its transformation does not have congruent shapes.
Answer:
it is sin(1000)times 250/x
Step-by-step explanation:
Answer:
It was gained 4 1/4 points.
Step-by-step explanation:
- 7 1/8 - 1 5/8 + 13 = - 8 6/8 + 13 = - 8 3/4 + 13 = - 8 - 3/4 + 12 + 4/4 = 4 1/4
X^2-2x=-8 add 1 to both sides
x^2-2x+1=-7 now the left side is a perfect square
(x-1)^2=-7 take the square root of both sides
x-1=±√-7 add 1 to both sides
x=1±√-7 which is
x=1±i√7 so
x=1+i√7 and 1-i√7
Answer : The volume of box B is 
Step-by-step explanation :
Given :
Volume of box A = 512 cubic meter
Let us assumed that the box A and box B are cubes and the dimensions of cube are same i.e, 'a'.
Volume of box A = V = 
As per question,
When dimensions of box A divided by 2 then the volume of box B will be:
Volume of box A = V' = 
As the box B is similar to box A. So, the volume of box B will be:
Volume of box B = V' = 
Therefore, the volume of box B is
