Permutations are all possible variations, in which a set of numbers or characters can be ordered. <span>The number of permutations on a set of </span><span> n elements is given by </span><span> n!. </span>In our case we have 9 digits, which means 9 elements. 
There are 9!=9*8*7*6*5*4*3*2*1=362880 possible variations, or 362880 possible identification numbers.

Assume that the growth rate of a population of ants is proportional to the size of the population at each instant of time. Suppo
Nutka1998 [239]
(1/A)  dA/dt=  C where A is the population of ants and C is a constant
ln(A) = C*t + C1 where C1 is another constant that comes out of integration and t is time in days.
Plugging in: at t=0, A= 100 so C1 = ln(100) = 4.605
at t=3, A=230 so ln(230) = 3*C +4.605 so C = 0.278
Final equation:
ln(A) = 0.278t + 4.605
or:
A = exp(0.278t + 4.605)
After 14 days, A = exp(0.278*14 + 4.605) = 4875.2

Solve by factoring: 2x2 - 5x - 12 = 0
Zepler [3.9K]

Step-by-step explanation:

2 {x}^{2}  - 5x - 12

2 {x}^{2}   - 8x  + 3x - 12

2x(x - 4) + 3(x - 4)

2x  + 3 = 0 \:  \: x - 4 = 0

x =  \frac{ - 3}{2}  \:  \: x =4
