Answer: There are 15120 distinct permutations.

Step-by-step explanation:

Since we have given that

ADDRESSEE

Here, 1 A,

2 D

2 S

3 E

Total number of letters in this word = 9

So, Number of permutations would be

$\dfrac{9!}{3!\times 2!\times 2!}\\\\=15120$

Hence, there are 15120 distinct permutations.

The average number of vehicles waiting in line to enter a parking lot can be modeled by the function f (x )equalsStartFraction x

ankoles [38]

Answer:

The rate of change of the number of vehicles waiting with respect to the traffic intensity for the intensities are:

a) 0.52

b) 2.63

Step-by-step explanation:

The rate of change of a function at a given point P can be obtained by evaluating the 1st derivative of the function in P. Thus,

$f(x)=\frac{x^2}{2(1-x)}$

$\frac{df(x)}{dx} = \frac{d(\frac{x^2}{2(1-x)})}{dx} \\\frac{df(x)}{dx} =\frac{x}{1-x} + \frac{x^2}{2(1-x)^2} \\\frac{df(x)}{dx} = -\frac{x(x-2)}{2(x-1)^2}$

Now for we just need to evaluate in each of the given points

a) $\frac{df(0.3)}{dx} =-\frac{0.3(0.3-2)}{2(0.3-1)^2}\\\boxed{\frac{df(0.3)}{dx} =0.520408 \approx 0.52}$

b) $\frac{df(0.6)}{dx} =-\frac{0.6(0.6-2)}{2(0.6-1)^2}\\\boxed{\frac{df(0.6)}{dx} = 2.625\approx 2.63}$

What comes next in the sequence: 1, 3, 11, 43,

lianna [129]

There may be more than one solution, but if we take the difference between the numbers of the sequence, we get
3-1, 11-3, 43-11
=2,8,32
which are powers of 2
=2^1, 2^3,2^5
If we believe the next difference is 2^7=128, then the next in the sequence will be 43+128=171
