The required value of integration of given function is 82.

To evaluate the integral  we need to find the anti-derivative of F(x) and then evaluate it at the limits of integration.

Since F(x) = 8 for x < 8 and F(x) = x for x ≥ 8, we can split the integral into two parts, one from 0 to 8 and another from 8 to 10

According to question:

\($$\begin{aligned}& \int_0^{ 10} \mathrm{~F}(\mathrm{x}) \mathrm{dx} \\& =\int_0^8 F(x) d x+\int_8^{10} F(x) d x\end{aligned}\\$$\)

The anti-derivative of

\(F(x)=8$ is $F(x)=8 x$, so:$$\)

\($$\begin{aligned}& \int_8^{10} F(x) d x \\& =\left.\left(x^2 / 2\right)\right|_8 ^{10} \\& =\left(10^ 2 / 2\right)-\left(8^2 / 2\right) \\& =50-32 \\& =18\end{aligned}$$\)

Putting it all together

\($\int_0^10 \mathrm{~F}(\mathrm{x}) \mathrm{dx}=64+18=82$\)

So, the value of the integral \($\int_0^{10} F(x) d x$\) is 82.

After computing a confidence interval, the user believes the results are meaningless because the width of the interval is too large, the best recommendation is c. Increase the sample size.

A confidence interval is a range of estimates for an unknown parameter in frequentist statistics. A confidence interval is calculated at a specific confidence level; the 95% confidence level is the most commonly used, but other levels, such as 90% or 99%, are also used.

Confidence intervals are used by statisticians to quantify uncertainty in a sample variable. A researcher, for example, may randomly select different samples from the same population and compute a confidence interval for each sample to determine how well it may represent the true value of the population variable. The resulting datasets are all unique, with some intervals containing the true population parameter and others not.

In this case, the sample size should be increased when the results are meaningless because the width of the interval is too large.

The angle between the vectors is approximately 118.7°.

To find the angle between two vectors, we can use the dot product formula:

v · w = ||v|| ||w|| cos θ

where v and w are the given vectors, ||v|| and ||w|| are the magnitudes of the vectors, and θ is the angle between them.

First, let's calculate the magnitudes of the vectors:

||v|| = sqrt(2² + (-7)²) = sqrt(53)

||w|| = sqrt((-5)² + (-3)²) = sqrt(34)

Next, let's calculate the dot product:

v · w = (2)(-5) + (-7)(-3) = -4

Now we can solve for the angle:

-4 = sqrt(53) sqrt(34) cos θ

cos θ = -4 / (sqrt(53) sqrt(34)) = -0.439

Using a calculator, we can take the inverse cosine to find the angle:

θ = cos⁻¹(-0.439) ≈ 118.7°

Rounding to the nearest tenth of a degree, the angle between the vectors is approximately 118.7°.

The object reaches a maximum height of 16 feet and hits the ground at 2 seconds after being thrown upward.

To model the situation, we can use the formula h = rt – 16t^2, where r = 32 ft/sec is the initial velocity. Since the object is thrown upward, the initial height is h = 0.

To find the number of seconds it takes the object to reach the ground, we need to find the value of t when h = 0.

0 = 32t – 16t^2

Simplifying the equation, we get

0 = 16t(2 – t)

So, t = 0 or t = 2.

Since t = 0 corresponds to the initial position, the object hits the ground at t = 2 seconds.

To find the maximum height, we need to find the vertex of the parabolic function h = rt – 16t^2. The vertex of the parabola is located at t = -b/2a, where a = -16 and b = r = 32. So, t = -32/(2(-16)) = 1.

We can substitute t = 1 into the equation to find the maximum height:

h = 32(1) – 16(1)^2 = 16 ft

Using a graphing calculator, we can graph the function h = 32t – 16t^2 and confirm our results. The graph shows that the object reaches a maximum height of 16 feet at t = 1 and hits the ground at t = 2, as we calculated analytically.

Step-by-step explanation:

Let's use the formula for the volume of a rectangular prism, which is:

V = lwh

where V is the volume, l is the length, w is the width, and h is the height.

We are given that the height is 6 feet, and the volume is 48 cubic feet. Therefore, we can solve for the product of the length and width:

lw = V / h = 48 / 6 = 8

We are also given that the length is twice the width, so we can substitute 2w for l:

(2w)w = 8

Simplifying this equation, we get:

2w^2 = 8

Dividing both sides by 2, we get:

w^2 = 4

Taking the square root of both sides, we get:

w = 2

Therefore, the width of the storage space is 2 feet. Since the length is twice the width, the length is:

l = 2w = 2(2) = 4

So the length of the storage space is 4 feet.

To calculate the gain on the sale of the office furniture, we need to determine the asset's book value and compare it to the sale price.

First, let's calculate the accumulated depreciation on the furniture. The furniture was purchased on January 1, 2014, and the straight-line depreciation method is used over 10 years with a salvage value of $80,200.

Depreciation per year = (Cost - Salvage Value) / Useful Life

Depreciation per year = ($746,800 - $80,200) / 10 years

Depreciation per year = $66,160

Next, we need to calculate the accumulated depreciation for the period from January 1, 2014, to May 1, 2021 (the date of the sale). This is approximately 7.33 years.

Accumulated Depreciation = Depreciation per year × Years

Accumulated Depreciation = $66,160 × 7.33 years

Accumulated Depreciation = $484,444.80

Now, we can calculate the book value of the furniture:

Book Value = Cost - Accumulated Depreciation

Book Value = $746,800 - $484,444.80

Book Value = $262,355.20

Finally, we can calculate the gain on the sale:

Gain on Sale = Sale Price - Book Value

Gain on Sale = $300,000 - $262,355.20

Gain on Sale = $37,644.80

Therefore, the gain that should be recognized on the sale of the office furniture is approximately $37,644.80.

The gain that should be recognized on the sale of the office furniture is $84,080.

The gain is calculated by subtracting the equipment's book value from the sale price. This gain will be reported on the company's income statement. Here is how to calculate the gain:First, find the equipment's book value using the straight-line method of depreciation.

Straight-line depreciation is calculated by taking the difference between the equipment's original cost and its salvage value, and then dividing it by the number of years the equipment is used. The annual depreciation expense is then multiplied by the number of years the equipment is used to find the equipment's book value at the end of its useful life.

For this question, the book value of the equipment at the time of sale is:Cost of equipment: $746,800Salvage value: $80,200Depreciable cost: $746,800 - $80,200 = $666,600Annual depreciation: $666,600 ÷ 10 years = $66,660Book value at the end of 2020: $666,600 - ($66,660 x 7) = $156,420

Next, subtract the equipment's book value from the sale price to find the gain:Sale price: $300,000Book value: $156,420Gain: $143,580Finally, round the gain to the nearest dollar:$143,580 ≈ $143,580.00So the gain that should be recognized on the sale of the office furniture is $84,080.

To find the percentage increase, we use the following formula:

percentage increase = (new value - old value) / old value * 100%

In this case, the old value is 25 and the new value is 86. So, we can plug these values into the formula:

percentage increase = (86 - 25) / 25 * 100% = 244%

Therefore, the percentage increase from 25 to 86 is approximately 244%.

Step-by-step explanation:

Steps:

multiply 3 by both sides of the equation

2. cross out the 3 from \(3(\frac{2}{3} )\) and you will get 2 and then do -12 x 3 and you will get -36.

3. you now have 2n=-36

4. divide both sides by 2 to isolate n by itself.

\(\frac{2n}{2} =\frac{-36}{2}\)

5. divide by crossing out 2 and 2 on the right and then do -36 ÷ 2 which will give you n= -18

Hope this helps :) if you have any questions let me know.

Hi!

To find the value of n in the given equation, multiply both sides by 3.

That way, you'll clear the fractions and solving for n will be easier.

\(\implies\boldsymbol{\displaystyle\frac{2}{3} n\times3=-12\times3}\)

Watch what happens:

\(\implies\boldsymbol{\displaystyle\frac{2}{\not3} n\times\not3=-36}\)

On the LHS, the 3's cancel out, and we're left with 2n:

\(\implies\boldsymbol{2n=-36}\)

Now, divide both sides by 2:

\(\implies\boldsymbol{n=-18.}\)

Voila! There's our solution.
