[tex]\rm \: f(x) = log(1 + x) - \dfrac{2x}{x + 2}[/tex]

~Let first define the domain of f(x).

[tex]{ \underline { \underline{ {\rule{200cm}{0.4cm}}}}}[/tex]

[tex]\sf \: f(x) = log(1 + x) - \dfrac{2x}{x + 2}[/tex]

w. r. t. x, we get

[tex]\rm {\: \longmapsto\dfrac{d}{dx}f(x) =\dfrac{d}{dx}\bigg[ log(1 + x) - \dfrac{2x}{x + 2}}[/tex]

[tex]\boxed{\sf{ \longmapsto\dfrac{d}{dx}logx \: = \: \dfrac{1}{x}}}[/tex]

[tex]\boxed{\sf{\longmapsto \dfrac{d}{dx} \dfrac{u}{v} = \dfrac{v\dfrac{d}{dx}u \: - \: u\dfrac{d}{dx}v}{ {v}^{2} } \: }}[/tex]

~So, using these results, we get

[tex]\sf {\:\longmapsto f'(x) = \dfrac{1}{x + 1} - \dfrac{(x + 2)\dfrac{d}{dx}2x - 2x\dfrac{d}{dx}(x + 2)}{ {(x + 2)}^{2} }}[/tex]

And-

☼︎~So, using this result, we get

[tex]\rm \: f'(x) = \dfrac{1}{x + 1} - \dfrac{(x + 2)2 - 2x(1 + 0)}{ {(x + 2)}^{2} }f′(x)=x+11−(x+2)2(x+2)2−2x(1+0)\rm \: f'(x) = \dfrac{1}{x + 1} - \dfrac{2x + 4 - 2x}{ {(x + 2)}^{2} }[/tex]

Given that,

\hat p= 0.5 ( assume 0.5)

1 - \hat p = 1 - 0.5= 0.5

margin of error = E = 4% = 0.04

At 95% confidence level the z is ,

\alpha = 1 - 95% = 1 - 0.95 = 0.05

\alpha / 2 = 0.05 / 2 = 0.025

Z\alpha/2 = Z0.025 = 1.960 ( Using z table )

Sample size = n = (Z\alpha/2 / E)2 * \hat p * (1 - \hat p )

= (1.960 / 0.04)2 * 0.5 * 0.5

= 600.25

Sample size =601

     The line is positive because it is going upwards. The y-intercept is positive 3. It can be found by seeing where the line intercepts the y-axis. The slope of the line is 2 and it can be found by using "rise over run."

Step-by-step explanation:

So we have to calculate 45% of 48 then add it to 48 to get the the weight of the new box.

(45/100)*48 = 21.6

48+21.6=69.6

Therefore, the weight of the new box is 69.9oz

Answer:

  (x +5)^2 +(y -3)^2 = 36

Step-by-step explanation:

Add the squares of half the linear term coefficients, then rewrite using squares. You get the standard form equation of a circle.

  x^2 +10x +y^2 -6y = 2

  (x^2 +10x +5^2) +(y^2 -6x +(-3)^2) = 2 +5^2 +(-3)^

  (x +5)^2 +(y -3)^2 = 36 . . . . . circle centered at (-5, 3) with radius 6

Answer:

well you could write this as

0.2222 of growth in a month

Step-by-step explanation:

2/3feet / 3 months

Answer:

The rate of growth of sprout seed in 3 months is 1.14%

Step-by-step explanation:

Given as:

The length of seed sprout grew =  foot

The time period for sprout grew = 3 month

Let The rate of sprout grew = r%

Let The initial length of seed = l foot

So, The length of seed sprout grew after 3 months =   × l foot

Now, According to question

The length of seed sprout grew after n months =  

Or ,   × l  =  

Or,  =  

Or, 1 +  =  

Or,  = 1.14

∴ r = 1.14 ×100 = 114

So, The rate of growth = r = 1.14 %

Hence The rate of growth of sprout seed in 3 months is 1.14%

Answer:

3(6-x)=15

Step-by-step explanation:

Using the mean concept, it is found that:

The mean of a data-set is given by the sum of all observations divided by the number of observations.

For Florida Company(FC):

Thus, the mean is:

[tex]M = \frac{-5 + 15 + 20}{3} = \frac{30}{3} = 10[/tex]

The mean return for Florida Company is 10%.

For Minnesota Company(MC):

Thus, the mean is:

[tex]M = \frac{8 + 8 + 20}{3} = \frac{36}{3} = 12[/tex]

The mean return for Minnesota Company is 12%.

Answer:

x≤90 and 30x+20y≥380,000

Step-by-step explanation:

1. x=original price of shoe

"at most" means inequality where the money you can spend is less than or equal to

so x-10≤80

solve for original price

x≤90

2. x=number of floor tix

Answer:

281.6

Step-by-step explanation:

=281.6 × 125 %

= 352

Answer:

35.51%, or, if rounded is 36%

Step-by-step explanation:

1. We assume, that the number 352 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 352, so we can write it down as 100%=352.

4. We know, that x% equals 125 of the output value, so we can write it down as x%=125.

5. Now we have two simple equations:

1) 100%=352

2) x%=125

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=352/125

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 125 is what percent of 352

100%/x%=352/125

(100/x)*x=(352/125)*x       - we multiply both sides of the equation by x

100=2.816*x       - we divide both sides of the equation by (2.816) to get x

100/2.816=x

35.511363636364=x

x=35.511363636364

now we have:

125 is 35.511363636364% of 352

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

Let's take the fraction as x/y , where x = numerator & y = denominator.

Given,

1st condition :-

[tex] \rightarrow \frac{x + 1}{y - 1} = 1 \: \: \: \: \: \: \: \: \: - - (1) \\ [/tex]

2nd condition :-

[tex] \rightarrow \frac{x}{y + 1} = \frac{1}{2}\: \: \: \: \: \: \: \: \: - - (2) \\ [/tex]

__________________

Now, let's take eq. (2) & find the value of x using cross multiplication.

[tex] \frac{x}{y + 1} = \frac{1}{2} \\ 2x = 1(y + 1) \\ 2x = y + 1 \\ x = \frac{y + 1}{2} [/tex]

We got x as y+1/2. Now, let's substitute this value of x in eq. (1) & solve it using cross multiplication.

[tex] \frac{x + 1}{y - 1} = 1 \\ \frac{ \frac{y + 1}{2} + 1 }{y - 1} = 1 \\ \frac{ \frac{y + 1}{2} + 1}{y - 1} = \frac{1}{1} \\ \frac{y + 1}{2} + 1 = y - 1 \\ \frac{y + 3}{2} = y - 1 \\ y + 3 = 2(y - 1) \\ y + 3 = 2y - 2 \\ y - 2y = - 2 - 3 \\ - y = - 5 \\ \boxed{ y = 5}[/tex]

The value of y is 5. Now, let's find x. (x = y+1/2)

[tex]x = \frac{y + 1}{2} \\ x = \frac{5 + 1}{2} \\ x = \frac{6}{2} \\ \boxed{x = 3}[/tex]

So, the values of x & y respectively are 3 & 5. Now, the required fraction will come in the form of x/y. So, the fraction is...

[tex] \frac{x}{y} \\ = \large\boxed{\boxed{ \bf\frac{3}{5} }}[/tex]
