To be congruent only translation, rotations and reflections are allowed
1)
(x, y) → (2x, y)=scale->not congruent
(x, y) → (x , y + 7)
(x, y) → (–x, –y)
2)
(x, y) → (x – 5, y)=translation
(x, y) → (x, –y)=reflection
(x, y) → (0.75x, 0.75y)=scale->not congruent
3)
(x, y) → (–x, y)=reflection
(x, y) → (3x, 3y)=scale->not allowed
(x, y) → (x – 9, y)
4)
(x, y) → (–x, –y)=reflection
(x, y) → (x + 4, y)=transformation
(x, y) → (x, y – 1)=transformation
->is congruent

so 4) is a series of transformations with a congruent after image

A hacker is trying to guess someone's password. The hacker knows (somehow) that the password is 10 characters long, and that eac
Gnoma [55]

The probability that the hacker guesses the password on his first try is:

P = 1/(62^10) = 1.19*10^(-18)

We know that the password is 10 characters long.

In each one of these, we can put.

One lower case letter (26 of these)

One upper case letter (26 of these)

one numerical digit (10 of these)

So, for every single digit, we have a total of:

26 + 26 + 10 = 62 options

Now we can find the total number of different passwords, which will be equal to the product between the number of options for each one of the characters.

We know that for each character we have 62 different options.

And we have 10 characters.

Then the product between the numbers of options is:

C = 62^10

Then if the hacker does a random guess, the probability that the random guess is correct is one over the total number of possible combinations.

P = 1/C = 1/(62^10)

The probability that the hacker guesses the password on his first try is:

P = 1/(62^10) = 1.19*10^(-18)

Let’s solve where they have a triangle, so the height is 9 cm, the base is 3 cm:

1/2 • 9 • 3 = 13.5

Since there’s 2 triangles we do:

13.5(2) = 27

Now the rectangle in the middle, where the height is 9cm and the base is 12cm:

12 • 9 = 108

Add up the areas:

108 + 27 = 135

Statement : Val spent $ 34 for the 2 items

contradiction : Neither of the 2 items that Val bought cost more then $ 15

think about it....if neither of them cost more then 15....lets say they cost 15 each...then there is no way he spent $ 34.....he would spend at most $ 30
