Reason:

Focus on the numerator for now. The [tex](11^8)^2[/tex] is the same as [tex]11^{16}[/tex] because we multiply the exponents. The general rule is [tex](a^b)^c = a^{bc}[/tex]

Alternatively we can think of it like this

[tex](11^8)^2 = (11^8)(11^8) = 11^{8+8} = 11^{16}[/tex]

So far we have [tex]\frac{(11^8)^2}{11^3} = \frac{11^{16}}{11^3}[/tex]

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

The last step is to subtract exponents due to the rule [tex]\frac{a^b}{a^c} = a^{b-c}[/tex] and the order of subtraction is important.

Therefore, [tex]\frac{(11^8)^2}{11^3} = \frac{11^{16}}{11^3} = 11^{16-3} = 11^{13}[/tex]

Absolute advantage theory

In his book The Wealth of Nations, the 18th-century economist Adam Smith proposed the concept of absolute advantage to describe how countries could benefit from trade by specializing in producing and exporting the goods that they can make more successfully than other countries.

On the other hand, China, Thailand, and Vietnam create and export low-cost manufactured goods. These three countries benefit greatly from their much lower unit labor costs.

Answer: 1/2  ([tex]\pi[/tex]) sin [tex]\pi[/tex] +  ∫ x cos [tex]\pi ^{2}[/tex] dx + c

               1/2 ([tex]\frac{\pi }{2}[/tex]) sin [tex]\frac{\pi }{2}[/tex] +  ∫ x cos [tex]\frac{\pi }{2} ^{2}[/tex] dx + c

Step-by-step explanation:

We can't just integrate straight away, so we try substitution.

While trying substitution, we observe that we could integrate cos([tex]x^{2}[/tex]) x dx

by substitution.

So, let's split the integrand and use integration by parts.

we can represent θ = x,

so, we can write,

                                = ∫[tex]x^{3} cos x^{2} dx[/tex]

                                = ∫ [tex]x^{2} cos (x^{2} )xdx[/tex]

We notice that we could rewrite this as ∫ u cos(u) 1/2 du, but we don't see how to integrate that, so we'll continue with parts for now.)

                            = ∫ [tex]x^{2} cos (x^{2} )xdx[/tex]

Let    u=[tex]x^{2}[/tex]         and      dv = [tex]cos(x^{2} )xdx[/tex]

Clearly     du= 2x dx,    and

we can integrate  dv by substitution to get.

                          = 1/2 sin [tex]x^{2}[/tex]

uv - ∫ vdu = 1/2 [tex]x^{2}[/tex] sin([tex]x^{2}[/tex]) - ∫ x sin ([tex]x^{2}[/tex]) dx

Integrate by substitution again to finish.

∫ [tex]x^{3} cos (x^{2}) dx[/tex] = 1/2 [tex]x^{2} sin x^{2}[/tex] + ∫ x cos [tex]x^{2}[/tex] dx + c

Then,

   x = √[tex]\pi[/tex]    and     √[tex]\frac{\pi }{2}[/tex]

 ∫ [tex]x^{3}[/tex] cos [tex]x^{2}[/tex] dx = 1/2 (√[tex]\pi ^{2}[/tex]) sin √[tex]\pi ^{2}[/tex] + ∫ x cos [tex]\pi ^{2}[/tex] dx + c

                        = 1/2 ([tex]\pi[/tex]) sin [tex]\pi[/tex] +  ∫ x cos [tex]\pi ^{2}[/tex] dx + c

∫  [tex]x^{3}[/tex] cos [tex]x^{2}[/tex] dx = 1/2 ([tex]\frac{\pi }{2}[/tex]) sin [tex]\frac{\pi }{2}[/tex] +  ∫ x cos [tex]\frac{\pi }{2} ^{2}[/tex] dx + c

The ordered pair given are not inverse to each other because:

When two functions are inverse to each other substituting a value A in function say AA will give answer say X, substituting the answer X to the the other function say BB returns the value A.

Instance

say function AA, plug in A gives X

the inverse will be:

say function BB plug in X gives A

So, we have  f(x)=2x+5 and g(x)= x-5/2

plugging in say 5/2 in f(x) will give

f(x) = 2 * 5/2 + 5

f(x) = 5 + 5

f(x) = 10

We plug in 10 to g(x)= x-5/2

g(x) = 10 - 5/2

g(x)= 7/2

since 7/2 ≠ 5/2 the pair of functions are not inverse to each other

So, we know that

Conditional probability P( A IIIrd | A Ist ) = [tex]\frac{P(III^{rd} \cap I^{st}) }{P(I^{st})}[/tex]

From question,

P( A IIIrd ∩ A Ist) = 12/x. and

P(A Ist) = 27/12.

Now, putting the values

So, we will get

              P( IIIrd | Ist ) = [tex]\frac{P(III^{rd} \cap I^{st}) }{P(I^{st})}[/tex]

              P( IIIrd | Ist ) = [tex]{(\frac{12}{x})}\div {(\frac{27}{x} )}[/tex]

And the solution is x = 21.

Here we have the sentence:

" The sum of 2 and a number is 23."

Let's define x as the number, then we can write the equation:

x + 2 = 23

This is a simple linear equation, to solve this we need to subtract 2 in both sides of the equation, we will get:

x + 2 - 2 = 23 - 2

Answer:

I don't know and your read in which class

For the given set of data, the value of mean is 83, median is 87 and standard deviation is 11.03

Standard deviation is a measurement of how evenly distributed a set of numbers is. Since the variance is the average of the squared deviations from the mean, it is the square root of the variance.

The mean score is - Sum of all scores / total number of scores

= 89 + 72 + 96 + 87 + 64 + 93 + 80 / 7

= 83

So the mean of given scores is 83

Median = central term

= 64, 72, 80, 87, 89, 93, 96

Median = 87

Mode of the data is - no mode as there are no recurring terms given

Standard deviation -

variance = (89 - 83)² +(72 - 83)² + (96 - 83)² + (87 - 83)² + (64 - 83)² + (93 - 83)² + (80 - 83)² / 7

= 121.71

f(x) has a greater slope.

The slopes of f(x) and g(x) are the same.

The slope of g(x) is undefined.

Answer:

After the solution, we can conclude that (A) the slope of f(x) is higher.

Step-by-step explanation:

What is the slope?

A line's steepness can be determined by looking at its slope.

The slope is calculated mathematically as "rise over run" (change in y divided by change in x).

The letter M stands for the slope of a function of the form y=Mx+C, so the slope of the function F(x) =4.

Now that you have a function but can only evaluate it using a table, you can determine the slope using the following formula:

Simply choose two points from the table to enter into the formula; in this example, we'll use points (4, 7) as our points 1 and our second point is (6,9).

This implies:

x¹ = 4y¹ = 7

x² = 6y² = 9

You just need to enter it into the formula:

m = 9-7/6-4

m = 2/2

m = 1

Now that we know both slopes, you can see that g(x) has a slope of 1, while f(x) has a slope of 4, indicating that f(x) has a steeper slope than g(x).

The instantaneous rate of change is simply the change in the derivative value at a specific point.

Given the data in the question;

To determine the instantaneous rate of change of the function, first find the derivative of the function.

f(x) = −4x² − 3x + 1

Applying sum rule, with respect to x

d/dx[ -4x² ] + d/dx[ -3x ] + d/dx[ 1 ]

[ 2 × -4x¹ ] + [ 1 × -3x⁰ ] + d/dx[ 1 ]

[ -8x ] + [ -3 ] + d/dx[ 1 ]

-8x - 3 + d/dx[ 1 ]

Differentiate using constant rule

-8x - 3 + [ 0 ]

-8x - 3

f'(x) = -8x - 3

Next, plug x = -3 into the derivative and simplify.

f'(x) = -8x - 3

f'(-3) = -8(-3) - 3

f'(-3) = 24 - 3

f'(-3) = 21
