Choose the explanation that shows why ΔADE is similar to ΔABC.
Natasha2012 [34]

Recall that a dilation with center (0, 0) and scale factor k maps (x,y) onto (kx, ky).

Now, triangle ADE is formed by

A=(0,0),\quad D=(0,2),\quad E=(4,0)

Whereas triangle ABC is formed by

A=(0,0),\quad B=(0,4),\quad C=(8,0)

In other words, the coordinates of B and C can be obtained by multiplying by 2 the coordinates of D and E.

This means that you get ABC from ADE by dilating with center (0,0) and scale factor 2.

Answer:

4,151,347,200

Step-by-step explanation:

To find how many ways the train can be made up we use the permutation formula and the values given.

n = 16

k = 9

_{n}P_{k}=\dfrac{n!}{(n-k)!}

_{16}P_{9}=\dfrac{16!}{(16-9)!}

_{16}P_{9}=\dfrac{16!}{7!}

_{16}P_{9}=4,151,347,200

So there will be 4,151,347,200 different ways that the train can be made.
