What is the domain and derivative of f(x)=ln(2xsqrt(2+x))?

harkovskaia [24]

Domain is the numbers yo can use
we has a sqrt and a ln
we cant have any neagtive ln's or sqrts
x cannot be negative
it cannot be 0 either
domain is all numbers bigger than 0

deritivive
apply chain rule
dy/dx(f(g(x))=f'(g(x))g'(x)
and also
dy/dx (lnx)=1/x
and
dy/dx(f(x)g(x))=f'(x)g(x)+g'(x)f(x)
and from experience
dy/dx(sqrtx)=1/(2√x)

so

dy/dx(ln(2xsqrt(2+x)))=
(1/(2xsqrt(2+x))(2)(sqrt(2+x)+(x/(2sqrt(2+x))=
(3x+4)/(2x(x+2))

domain is all real numbers greater than 0
derivitive is $\frac{3x+4}{2x(x+2)}$

There are 16 players in my poker group that meets the first Tuesday of every month. Ten of the players are male and six are fema

rodikova [14]

Answer: Hello mate!

in your group, there are 16 players, 10 males, and 6 females.

in this case, 5 males already arrived (then there are 5 other males left)

and 4 females already arrived (then there are other 2 females left)

then there are a total of 7 players left, where 2 are female and 5 are males.

you want to know the probability that the next person through the door will be a male.

this is the number of male players left, divided by the number of players left: 5/7 = 0.71

then the probability that the next person through the door will be a male is 0.71.

Correctly complete this sequence: 88511, 16351, ?, 10251

IgorC [24]

Answer:

73155 will be the 3rd number in the sequence: 88511, 16351, ?, 10251.

So, the complete sequence will be: 88511, 16351, 73155, 10251.

Step-by-step explanation:

As 88511 is the first number.

The number 88511 has a certain pattern that could help us finding the next number.

So, let us consider 88511 and determine the pattern to find the next number and so on to complete the sequence.

Adding the first 2 digits in the number 88511 i.e. 8 + 8 = 16

Subtracting the 3rd digit from the 2nd digit i.e. 8 - 5 = 3

Multiplying the 3rd digit and 4th digit i.e. 5 × 1 = 5

Dividing the 4th digit by the 5th digit i.e. 1 ÷ 1 = 1

Hence, using these steps would get us the number 16351.

So, the next number would obtained using same steps:

Adding the first 2 digits in the number 16351 i.e. 1 + 6 = 7

Subtracting the 3rd digit from the 2nd digit i.e. 6 - 3 = 3

Multiplying the 3rd digit and 4th digit i.e. 3 × 5 = 15

Dividing the 4th digit by the 5th digit i.e. 5 ÷ 1 = 5

Hence, using these steps would get us the number 73155.

So, the next number would obtained using same steps:

Adding the first 2 digits in the number 73155 i.e. 7 + 3 = 10

Subtracting the 3rd digit from the 2nd digit i.e. 3 - 1 = 2

Multiplying the 3rd digit and 4th digit i.e. 1 × 5 = 5

Dividing the 4th digit by the 5th digit i.e. 5 ÷ 5 = 1

Hence, using these steps would get us the final number 10251.

So, from this observation, we determine that 73155 will be the 3rd number<em> </em>in the sequence: 88511,16351,?,10251.

So, the complete sequence will be: 88511, 16351, 73155, 10251.
