A transformation of rectangle LMNO results in rectangle L'M'N'O'.
Helen [10]

Answer:

As you can see Rectangle L M NO and Rectangle L'M'N'O' are such that

1. Size of Rectangle L M NO > Size of Rectangle L'M'N'O'

2. Sides of, means length and breadth of Rectangle L M N O is not in proportion to Rectangle L'M'N'O'. i.e

    \frac{LM}{L'M'}=\frac{8}{6}=\frac{3}{2} \\\\\frac{LO}{L'O'}= \frac{4}{4}=1

3. Out of four possibilities given :

, Reflection and Rotation is not possible because in all the three cases Pre-image and image are not congruent or similar.

As in,Rectangle LMNO →when length and breadth get reduced by scale of 2 and 0 and Dilation by scale factor of< 1  we get Rectangle L'M'N'O'.Centre of dilation may be other than origin.

So, Stretching of preimage i.e Rectangle L M NO→ means Shrinking has taken place to get image Rectangle L'M'N'O'.As shrinking is not an option.

So, Dilation by a factor less than 1, center of dilation other than origin has taken place.

John draws a regular five pointed star in the sand, and at each of the 5 outward-pointing points and 5 inward-pointing points he
ycow [4]

Solution : Given points to be fill are : 5 external points + 5 internal points

Total positions to be fill are 5+5 = 10

given number of sea shell to be placed are = 10

Here all sea shell are different so each sea shell is different from any other sea shell

if we interchange the position of any two sea shell we would be getting totally different

arrangement .

We can think this problem like 10 sea shell are to be placed at 10 different places

We start with placing first sea shell .

In the beginning we have 10 positions

once it is placed we pick second sea shell and now we have only 9 vacant places

once it is placed we pick next ses shell and we have 8 vacant places for it

we continue with it till we place the last sea shell for which we would be having

only 1 vacant place.

This way the total number of arrangements we get : 10x9x8x7x6x5x4x3x2x1 = 3628800

ANSWER = 3628800
