Step-by-step explanation:

[tex]\large\underline{\sf{Solution-}}[/tex]

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

Let assume that

[tex]\rm :\longmapsto\:y = {cosec}^{ - 1} \bigg( \dfrac{1 + {x}^{2} }{2x} \bigg)[/tex]

We know,

[tex]\boxed{\tt{ {cosec}^{ - 1}x = {sin}^{ - 1}\bigg( \dfrac{1}{x} \bigg)}}[/tex]

So, using this, we get

[tex]\rm :\longmapsto\:y = sin^{ - 1} \bigg( \dfrac{2x}{1 + {x}^{2} } \bigg)[/tex]

Now, we use Method of Substitution, So we substitute

[tex] \red{\rm :\longmapsto\:x = tanz \: \rm\implies \:z = {tan}^{ - 1}x}[/tex]

So, above expression can be rewritten as

[tex]\rm :\longmapsto\:y = sin^{ - 1} \bigg( \dfrac{2tanz}{1 + {tan}^{2} z} \bigg)[/tex]

[tex]\rm :\longmapsto\:y = sin^{ - 1} \bigg( sin2z \bigg)[/tex]

[tex]\rm\implies \:y = 2z[/tex]

[tex]\bf\implies \:y = 2 {tan}^{ - 1}x[/tex]

So,

[tex]\bf\implies \: {cosec}^{ - 1}\bigg( \dfrac{1 + {x}^{2} }{2x} \bigg) = 2 {tan}^{ - 1}x[/tex]

Thus,

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

[tex]\rm \:  =  \: \dfrac{d}{dx}(2 {tan}^{ - 1}x)[/tex]

[tex]\rm \:  =  \: 2 \: \dfrac{d}{dx}( {tan}^{ - 1}x)[/tex]

[tex]\rm \:  =  \: 2 \times \dfrac{1}{1 + {x}^{2} } [/tex]

[tex]\rm \:  =  \: \dfrac{2}{1 + {x}^{2} } [/tex]

Hence,

[tex] \purple{\rm :\longmapsto\:\boxed{\tt{ \dfrac{d}{dx} {cosec}^{ - 1} \bigg( \dfrac{1 + {x}^{2} }{2x} \bigg) = \frac{2}{1 + {x}^{2} }}}}[/tex]

Hence, Option (d) is correct.

Answer:

30

Step-by-step explanation:

2/3 = 20/30

4/5 = 24/30

7/10 = 21/30

Answer: 30

Step-by-step explanation: 2/3 = 20/30, 4/5 = 24/30, 7/10 = 21/30

Answer:

The x-axis

Step-by-step explanation:

This line means, the line going through [tex](1, 0)[/tex] with [tex]m=0[/tex] means there is a flat line(m=0, 0 slope) with a y-value of [tex]0[/tex] from the point given.

So, the line is [tex]y=0[/tex], i.e. the x-axis.

So, graph the x-axis and we're done!

Answer:

3/8g + 2 = 5  

Subtract the number 2 from both sides of the equation.

3/8g = 3

Now divide 3/8 from both sides of the equation.

3/8 divided by 3/8 equals 0.  3 divided by 3/8 equals 8.

The final answer is:

g = 8

------------------------------------------------------------------------------------------

Check your answer:

3/8g + 2 = 5

Substitute 8 into the spot where the variable g was.

3/8 X 8 + 2 = 5

So our answer x = 8 is true.

Answer: X = 9

Step-by-step explanation:

First insert the function into a graphing calculator.

We are trying to find the x intercepts, we substitute y=0.

With a graphing calculator look at where the line intercepts the x axis, (9,0) , and we find that x=9.

Answer:

The answer is B because x = 4 so 12x4-3=45

Answer:

[tex]15x + 12x - 3 + 75 = 180 \\ 27x = 180 - 75 + 3 = 108 \\ x = 108 \div 27 = 4 \\ a = 12x - 3 = 12 \times 4 - 3 = 48 - 3 = 45[/tex]

Answer:

She made 138, 179 two point field goals and 118

3-point field goals during the regular season

Step-by-step explanation:

Answer:

118, 138, and 179 points

Step-by-step explanation:

x = 3-point goals

2-point goals = 2x - 57

free throws = 2x - 57 - 41

3x + 2x * (2x - 57) + (2x - 57 - 41) = 850

3x + 4x - 114 + 2x - 98 = 850

9x = 1062

x = 118

2x - 57 = 2 * 118 - 57 = 179

2x - 57 - 41 = 138

Answer:

[tex] - 3(5n - 8) = - 8(n - 3)[/tex]

[tex] - 15n + 24 = -8 n + 24[/tex]

[tex] - 7n = 0[/tex]

[tex]n = \frac{0}{ - 7} [/tex]

[tex]n = 0[/tex]

Answer:

A

Step-by-step explanation:

you just follow the trail

Answer:

A - 2

Step-by-step explanation:

It can't be B or D, because the other triangle is bigger than the first one.

It is not 4 because if you count the squares, you will notice that b=2 and a=4. So the scale factor is 2.

Answer:

138 I think

Step-by-step explanation:

2,000 - 750 ÷ 9 = 138

Answer:

x=176 degrees

Step-by-step explanation:

The first step to solving this is filling out any information we have. We know a solid line is 180 degrees, so the angle next to 92 must be 88.

We also know that the length of the line dividing 92 and 88 is equal to the other line with a small line in the middle. Because of this, the angle above the first 88 we found is also 88 degrees.

Now that we know two of the angles in the triangle add up to 176, we can figure out that the other angle is equal to 4. We know this because the sum of the interior angles of a triangle must equal 180.

This may seem off to you, but keep in mind that this diagram is likely not to scale.

Using the same rule we used for the first part we did, we can deduce that x equals 176.
