The value of the integral ∫√x/(x - 4) dx from 9 to 16 is 3.022

From the question, we have the following parameters that can be used in our computation:

∫√x/(x - 4) dx from 9 to 16

The above expression can be integrated using integration by parts method

When integrated, we have

∫√x/(x - 4) dx = 2(√x - ln(√x + 2) + ln(|√x - 2|))

Recall that the x values are from 9 to 16

This means that

∫√x/(x - 4) dx = 2(√16 - ln(√16 + 2) + ln(|√16 - 2|)) - 2(√9 - ln(√9 + 2) + ln(|√9 - 2|))

So, we have

∫√x/(x - 4) dx = 2(4 - ln(4 + 2) + ln(|4 - 2|)) - 2(3 - ln(3 + 2) + ln(|3 - 2|))

Solving further, we get

∫√x/(x - 4) dx = 2(4 - ln(6) + ln(2)) - 2(3 - ln(5) + ln(1))

Evaluate

∫√x/(x - 4) dx = 3.022

Hence, the value of the integral is 3.022

Answer:

-4,-3,-2,-1,0,1,2 are less than -5 and everything else is greater :)

Answer:

\(-7, -6,\) and \(-5\).

Step-by-step explanation:

The question asks for all numbers that are "no more than" -5. In other words, it is asking for every number listed that is less than or equal to -5. Of the numbers given, only -7, -6, and -5 fit that description.

Answer:

Step-by-step explanation:

The graph of g(x) = x^2+2 is the upward translation of the

graph of f(x) = x^2 by 2 units.

Therefore, the probability that more than 50% of the people in the sample are married is approximately 0.115 (rounded to three decimal places).

To solve this problem, we can use the normal approximation to the binomial distribution since the sample size is large (n = 1000) and the proportion of married persons (p) is not too close to 0 or 1.

The mean of the sample proportion can be calculated as:

μ = p = 0.482

The standard deviation of the sample proportion can be calculated as:

σ = sqrt((p * (1 - p)) / n) = sqrt((0.482 * (1 - 0.482)) / 1000) ≈ 0.015

To find the probability that more than 50% of the people in the sample are married, we need to calculate the z-score and find the area under the normal curve to the right of this z-score.

The z-score can be calculated as:

z = (x - μ) / σ = (0.5 - 0.482) / 0.015 ≈ 1.200

Using a standard normal distribution table or a calculator, we can find that the area to the right of z = 1.200 is approximately 0.1151.

For instance, a rectangle is a four-sided polygon that only has equal opposed sides but equal-sized angles. It is therefore an irregular polygon.

Equilateral (all sides are the same length) and equiangularity are requirements for a regular polygon (all angles of the same measure). Rectangles have equal angles. It cannot ever be regular since none of its sides can ever be the same length.

It is a regular quadrilateral as well.

due to the same length of its sides and angles. Like a rectangle, a square has four angles that are 90 degrees. It can also be visualized as a rectangle with equal lengths on its two adjacent edges.

The distance from the earth to venus is an illustration of the sine ratio

The distance from the earth to venus at that time is 1.12 au

See attachment for the diagram that illustrates the complete question.

Start by calculating the angle V using the following sine ratio

SE/sin(V) = VS/sin(E)

This gives

1/sin(V) = 0.723/sin(39.4)

Take the inverse of both sides

sin(V)/1 = sin(39.4)/0.723

Evaluate the quotient

sin(V) = 0.8779

Take the arcsin of both sides

V = 61.4

Calculate the measure of angle S

<S + <V + <E = 180

This gives

<S  = - <V - <E + 180

Substitute known values

<S  = -61.4 - 39.4 + 180

<S  = 79.2

The distance (VE) is then calculated using the following sine ratio

VE/sin(S) = VS/sin(E)

This gives

VE/sin(79.2) = 0.723/sin(39.4)

Multiply bot sides by sin(79.2)

VE = sin(79.2) * 0.723/sin(39.4)

Evaluate the product

VE = 1.12

Hence, the distance from the earth to venus at that time is 1.12 au

Answer: 1,150.4 centimeters³

Step-by-step explanation:

    We will plug 6.5 into the correct formula to solve. Why 6.5? If 13 is the diameter, and the radius is half the diameter, 13 / 2 = 6.5

-> Please note in my LaTeX, "(pi)" = π ≈ 3.14

     V = \(\frac{4}{3} (pi)r^{3}\)

     V = \(\frac{4}{3} (pi)(6.5)^{3}\)

     V ≈ 1,150.35

     V ≈ 1,150.4 centimeters³

The area of the parallelogram is \(\sqrt{132}\).

A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite sides of a parallelogram are equal in length, and the opposite angles are equal in measure. Also, the interior angles on the same side of the transversal are supplementary. Sum of all the interior angles equals 360 degrees.

Given that,

vertices k(1, 1, 3), l(1, 3, 5), m(6, 9, 5), and n(6, 7, 3)

Area of Parallelogram = |KL × KN|

KL = (1, 1, 3) - (1, 3, 5) = (0, 2, 2)

KN = (1, 2, 3) - (3, 7, 3) = (2, 5, 0)

Area of the parallelogram = cross product of two vectors, represented by the adjacent sides.

Area of Parallelogram = |(0, 2, 2) × (2, 5, 0)|

                                    = |i(2 × 0 - 5 × 2) - j(0 × 0 - 2 × 2) + k(0 × 5 - 2 × 2)|

                                    = |i(-10) - j(-4) + k(-4)|

                                    = |-10i + 4j - 4k|

                                    = \(\sqrt{(-10)^{2}+(4)^{2}+(-4)^{2} }\)

                                    = \(\sqrt{100+16+16}\)

                                    = \(\sqrt{132}\)

The intervals of concavity for f(x) = 3 cos x, with 0 < x < 21, are (0, π/2) and (3π/2, 2π).

To find the intervals of concavity for f(x) = 3 cos x, we need to analyze the second derivative of the function.

First, let's find the second derivative of f(x):

f'(x) = -3 sin x (derivative of cos x)

f''(x) = -3 cos x (derivative of -3 sin x)

Now, we can analyze the concavity of f(x) by considering the sign of the second derivative:

When x ∈ (0, π/2): In this interval, cos x > 0, so f''(x) < 0. The second derivative is negative, indicating concavity downwards.

When x ∈ (π/2, 3π/2): In this interval, cos x < 0, so f''(x) > 0. The second derivative is positive, indicating concavity upwards.

When x ∈ (3π/2, 2π): In this interval, cos x > 0, so f''(x) < 0. The second derivative is negative, indicating concavity downwards.

Answer:

(7, - 28 )

Step-by-step explanation:

y = x - 35 → (1)

y = - 4x → (2)

substitute y = x - 35 into (2)

x - 35 = - 4x ( add 4x to both sides )\

5x - 35 = 0 ( add 35 to both sides )

5x = 35 ( divide both sides by 5 )

x = 7

substitute x = 7 into either of the 2 equations

substituting into (1)

y = 7 - 35 = - 28

Answer:

Step-by-step explanation:

The surface area is equal to the sum of the areas of all the sides

This figure has sides of 2 triangles (bases) and 3 rectangles (lateral surface)

h (triangle) = 1m

We can find the base of the triangle by using the Pythagorean theorem (multiply by 2, because the triangle's base contains two of these identicals sides)

\((( {1.5})^{2} - {1}^{2} ) \times 2=( 2.25 - 1 ) \times 2= 1.25 \times 2 = 2.5> 0\)

The triangle's base is equal to:

\( \sqrt{2.5} = \frac{ \sqrt{10} }{2} \)

First, let's find the area of 2 bases (triangles):

\(a(bases) = 2 \times \frac{1}{2} \times 1 \times \frac{ \sqrt{10} }{2} = \frac{ \sqrt{10} }{2} \)

Now, we can find the whole surface area by adding the areas of the rectangles to the bases' areas:

\(a(surface) = \frac{ \sqrt{10} }{2} + 2.4 \times 2 + 1.5 \times 2 + 1.7 \times 2 = \frac{ \sqrt{10} }{2} + \frac{56}{5} ≈12.78\)

Answer:

Step-by-step explanation:

5x  + y = 11 -------------------(I)

3x - y = 9 -----------------(II)

Add equation (I) & (II)

   5x + y = 11

   3x - y = 9        {add and y will be eliminated and we'll get the value of x}

  8x       = 20

          x = 20/8

         x = 2.5

Plugin x = 2.5 in equation (I)

5*2.5 + y = 11

 12.5  + y = 11

            y = 11 - 12.5

            y = -1.5

After solving the equations simultaneously we get the value \(x=\frac{5}{2}\) and \(y=\frac{-3}{2}\).

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign .

We have,

\(5x + y = 11\)   \(.......... (i)\)

\(3x - y = 9\)   \(...........(ii)\)

To solve we will multiply equation \((i)\) by \(3\) and equation \((ii)\) by \(5\),

\(15x + 3y = 33\)   \(..........(iii)\)

\(15x -5y = 45\)   \(..........(iv)\)

Now, adding both equations \((iii)\) and \((iv)\) ,

We get,

\(8y=-12\)

\(y=-\frac{3}{2} =1.5\)

Now putting value of \(y=-\frac{3}{2} =1.5\) in equation \((i)\) ,

\(5x+(\frac{-3}{2} )=11\)

\(x=\frac{5}{2} =2.5\)

So, using the elimination method we find out the value \(x=\frac{5}{2}\) and \(y=\frac{-3}{2}\), which was find out simultaneously.

Hence, we can say that after solving the equations simultaneously we get the value \(x=\frac{5}{2}\) and \(y=\frac{-3}{2}\).

The orthogonal decomposition of `v` with respect to `w` is given by`v = proj_w(v) + v_ortho``v = <-0.5294, -2.1176> + <3.5294, 1.1176>``v = <3, -3>`

Given vectors `v = (3, -3)` and `w = span(1, 4)`.

To find the orthogonal decomposition of v with respect to w, we need to find two vectors - one in the direction of w and another in the direction orthogonal to w. Therefore, let's first find the direction of w.To get the direction of w, we can use any scalar multiple of the vector `w`.

Thus, let's take `w_1 = 1` such that `w = <1, 4>`.Now we need to find the projection of v onto w. The projection of v onto w is given by`(v . w / |w|^2) * w`

Here, `.` represents the dot product of vectors and `|w|^2` is the squared magnitude of w.`|w|^2 = 1^2 + 4^2 = 17` and `v . w = (3)(1) + (-3)(4) = -9`.

Therefore, the projection of v onto w is given by`proj_w(v) = (-9 / 17) * <1, 4> = <-0.5294, -2.1176>`We can check that `proj_w(v)` is in the direction of `w` by computing the dot product of `proj_w(v)` and `w`.`proj_w(v) . w = (-0.5294)(1) + (-2.1176)(4) = -9`.

Thus, the vector `proj_w(v)` is indeed in the direction of `w`.Now, we need to find the vector in the direction orthogonal to w. Let's call this vector `v_ortho`.

Thus,`v_ortho = v - proj_w(v) = <3, -3> - <-0.5294, -2.1176> = <3.5294, 1.1176>`
