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.

Answer:

The second: $\bold{f (x) =4(x+\frac34)^2-\frac{21}4}$

Step-by-step explanation:

$f (x) =4x^2+6x-3\\\\f (x) =4(x^2+\frac64x]-3\\\\f (x) =4[x^2+2\cdot x\cdot\frac34+(\frac34)^2-(\frac34)^2]-3\\\\f (x) =4[(x+\frac34)^2-(\frac34)^2]-3\\\\f (x) =4(x+\frac34)^2-4(\frac34)^2-3\\\\f (x) =4(x+\frac34)^2-\frac94-\frac{12}4\\\\\underline{f (x) =4(x+\frac34)^2-\frac{21}4}$
