grin007 [14]

Answer:

15,240,960 serial numbers

Step-by-step explanation:

Since no repeats are allowed and the order matters, the number of possible serial numbers is given by the product of the permutation of 4 out of 9 letters by the permutation of 4 out of 10 numbers:

$n=\frac{9!}{(9-4)!}*\frac{10!}{(10-4)!} \\n=9*8*7*6*10*9*8*7\\n=15,240,960$

There are 15,240,960 ways to generate a serial number.

Answer:

$\frac{3x^{4}+10x^{2} }{5}$

Step-by-step explanation:

$2x^{2} + x^{3}(\frac{6x}{10} )$

$2x^{2} + x^{3}(\frac{3x}{5} )$

$2x^{2} + \frac{3xx^{3}}{5}$

$\\ 2x^{2} + \frac{3x^{4}}{5}$

$\frac{5(2x^{2} )}{5} + \frac{3x^{4}}{5}$

$\frac{5(2x^{2} )+3x^{4}}{5}$

$\frac{10x^{2} +3x^{4}}{5}$

$\frac{3x^{4}+10x^{2} }{5}$

PLEASE HELP!!!!

Lilit [14]

Answer:

d. 40

Step-by-step explanation:

The number of faces, edges and vertices is related by the following formula:

$V - E + F = 2$

In which V is the number of vertices, E is the number of edges and F is the number of faces.

In this question:

$F = 25, V = 17$

We want to find E. So

$V - E + F = 2$

$17 - E + 25 = 2$

$E = 42 - 2 = 40$

The correct answer is given by option D.
