Comparing this to the original function, we see that it matches exactly. Therefore, the given factors of f(x) are verified.

To verify the given factors of f(x), we need to use polynomial long division. We divide f(x) by (2x + 1) and (3x - 2) separately to see if they are factors.

First, let's divide f(x) by (2x + 1):

    3x² + 25x - 11

2x + 1 | 6x³ + 53x² - 11x - 18

      - (6x³ + 3x²)

      ---------------

            50x² - 11x

            - (50x² + 25x)

            -------------

                    -36x - 18

                    - (-36x - 18)

                    -------------

                             0

Since the remainder is zero, (2x + 1) is a factor of f(x).

Next, let's divide f(x) by (3x - 2):

        2x² + 29x + 9

3x - 2 | 6x³ + 53x² - 11x - 18

        - (6x³ - 4x²)

        ---------------

                 57x² - 11x

                 - (57x² - 38x)

                 -------------

                         27x - 18

                         - (27x - 18)

                         ------------

                                  0

Again, the remainder is zero, so (3x - 2) is also a factor of f(x).

Therefore, we have:

f(x) = (2x + 1)(3x - 2)(3x + 3)

And we can check that this is correct by multiplying the factors together:

(2x + 1)(3x - 2)(3x + 3) = (6x² - 4x + 3x - 2)(3x + 3)

= 6x³ + 9x² - 8x - 6x² + 9x - 6

= 6x³ + 3x² + x - 6

Comparing this to the original function, we see that it matches exactly. Therefore, the given factors of f(x) are verified.

An equation is formed when two equal expressions. The time the same pump will take to empty a tank containing 108,000 gallons of water is 4.5 hours.

When two equal expressions are added together with the aid of the equal sign "=," an equation is created.

Given that the time it takes a water pump to empty a tank directly correlates with the tank's capacity. Consequently, the relationship can be expressed as,

V ∝ T

V = kT

Substituting the volume and time in the equation,

60,000 gallons = 2.5 hours × k

Solving the equation for k,

k = 60,000 gallons / 2.5 hours

k = 24,000 gallons per hour

Now, the equation for the relationship can be written as,

V = 24,000 gallons per hour × T

Now, the time the same pump will take to empty a tank containing 108,000 gallons of water is,

V = 24,000 gallons per hour × T

108,000 gallons = 24,000 gallons per hour × T

108,000 gallons / 24,000 gallons per hour = T

T = 4.5 hours

Hence, the time the same pump will take to empty a tank containing 108,000 gallons of water is 4.5 hours.

We use the chi-square distribution when making inferences about a single population variance.

Short Description of Chi-Square Distribution

The continuous probability distribution known as the chi-square distribution. The number of degrees of freedom (k) a chi-square distribution has determines its shape. This type of sampling distribution has a variance of 2k and a mean equal to its number of degrees of freedom (k). The range is of a chi-square distribution is from 0 to ∞.

Variance plays a key role in the analysis of risk and uncertainty. The sample variance, an unbiased estimator of population variance, is expressed by the following formula of core statistic for a sample size 'n' and Y' as the sample mean:

S² = ∑(Yₓ - Y') / (n-1)

The formula, (n-1)S² / σ² has the central chi-square distribution as χ²ₙ₋₁. Here (n-1) represents the degrees of freedom.

The marginal profit is a constant value of $27 per unit produced.

First, let's establish the revenue function. The revenue (R) is the product of the number of units sold (x) and the price per unit ($47). So, R(x) = 47x.

Next, let's find the profit function (P). Profit is the difference between revenue and cost: P(x) = R(x) - C(x). Plugging in the given functions, we get P(x) = (47x) - (160 + 20x + 6).

Now, to find the marginal profit P'(x), we need to take the derivative of the profit function with respect to x:

P'(x) = d/dx[(47x) - (160 + 20x + 6)]
P'(x) = 47 - 20

Therefore, the marginal profit P'(x) = 27. This means that, for each additional unit produced, the profit increases by $27.

Step-by-step explanation:

cos  2pi/3   =    -1/2

sin   2pi/3   =     sqrt (3)/2

cos   1 pi/6  =     sqrt(3)/2

sin   11 pi/6  =    - 1/2

so when you put in these values in  you will have :

(2*8) * (-1/2 + sqrt (3)/2 i )( sqrt(3)/2) + i (-1/2) )

= 16 ( - sqrt (3)4  + 1/4 i + 3/4 i - sqrt(3)/4  i^2 )        rememember i^2 =  - 1

The value of the given trigonometric expression \(\frac{\sin\theta-\cos\theta}{\tan\theta}\) is \(\frac{279}{1640}\).

We know the trigonometric identities,

The sum of squares of sine and cosine of an angle is unity.
\(\sin^2\theta+\cos^2\theta=1\)

The tangent of any angle is the ratio of the sine and cosine of that angle.
\(\tan\theta=\frac{\sin\theta}{\cos\theta}\)

The cosine of any angle is the ratio base to the hypotenuse of a right triangle.

The given expression is \(41\cos\theta=9\)  and we have to find  \(\frac{\sin\theta-\cos\theta}{\tan\theta}\).

\(41\cos\theta=9\\\cos\theta=\frac{9}{41}\)

Now, using the trigonometric identity \(\sin^2\theta+\cos^2\theta=1\), we get

\(\sin^2\theta+\cos^2\theta=1\)

Putting the value of cosθ, and finding the value of sinθ,

\(\sin^2\theta+(\frac{9}{41})^{2} =1\\\sin^2\theta+\frac{81}{1681} =1\\\sin^2\theta=1-\frac{81}{1681}\\\sin^2\theta=\frac{1681-81}{1681}\\\\\sin^2\theta=\frac{1600}{1681}\\\\\sin\theta=\sqrt{ \frac{1600}{1681}}\\\sin\theta=\frac{40}{41}\)

Now, finding the value of tanθ, as tangent is the ratio of sine and cosine of theta,

\(\tan\theta=\frac{\sin\theta}{\cos\theta}\\\\\tan\theta=\frac{\frac{40}{41} }{\frac{9}{41}}\\\\\tan\theta=\frac{40}{9}\)

Now, Putting the values in the expression and simplifying,

\(\frac{\sin\theta-\cos\theta}{\tan\theta}=\frac{\frac{40}{41}-\frac{9}{41} }{\frac{40}{9}}\\\\=\frac{\frac{40-9}{41} }{\frac{40}{9} } \\\\=\frac{31}{41}\times\frac{9}{40}\\\\=\frac{279}{1640}\)

Therefore, approximately 68.26% of people are expected to score higher than 2.5 but lower than 3.5.

Based on the information provided, the mean (X) is 3.00 and the standard deviation (SD) is 0.50. To find the percentage of people expected to score higher than 2.5 but lower than 3.5, we will use the standard normal distribution (z-score) table.

First, we need to calculate the z-scores for both 2.5 and 3.5:
z1 =\( (2.5 - 3.00) / 0.50 = -1.0\)
z2 = \((3.5 - 3.00) / 0.50 = 1.0\)

Now, we can use the standard normal distribution table to find the probability of the z-scores. For z1 = -1.0, the probability is 0.1587 (15.87%). For z2 = 1.0, the probability is 0.8413 (84.13%).

To find the percentage of people expected to score between 2.5 and 3.5, subtract the probability of z1 from the probability of z2:

Percentage = \((0.8413 - 0.1587) x 100 = 68.26%\)

Answer:

t = 10.9

Step-by-step explanation:

9.3-t=-1.6

Subtract 9.3 from each side

9.3-t-9.3=-1.6-9.3

-t =-10.9

Multiply each side by -1 to find t

t = 10.9

The value of T is 10.9.

To find this, you must first get T on a side by itself. To do so, subtract 9.3 from both sides. This leaves -t = -10.9. Finally, divide both sides by -1, to make T positive. Thus meaning T = 10.9.

Draw a diagram of a vertical wall with a ladder leaned against it.

You can say that the ladder is 8 meters long and the distance from the bottom of the ladder to the base of the wall is 2 meters..

Then ask the question At what height on the wall is the top of the ladder?

This is calculated using the Pythagoras theorem - the ladder is the hypotenuse used of the right angled triangle formed by the wall, ladder and the ground.

8^2 = x^2 + 2^2      where x is the required height.

x^2 = 8^2 - 2^2

x^2 = 60

x = sqrt60

The number of strikeouts in 36 innings by Warren is 45. The number of strikeouts in 80 innings is 96 while the number of strikeouts in 36 innings is 45. To compare the two, we need to know the number of strikeouts by Warren in 36 innings if he pitched for 80 innings.

Warren pitched 80 innings and got 96 strikeouts. The strikeouts he got in 36 innings is 45.So, the difference between the number of innings he pitched in both cases is: 80 - 36 = 44 innings.The number of strikeouts he got for the extra 44 innings is: 96 - 45 = 51 strikeouts.Therefore, Warren has more strikeouts in 80 innings than he has in 36 innings. The number of strikeouts is 96 and the number of innings is 80.

This can be confirmed by subtracting 45 strikeouts in 36 innings from 96 strikeouts in 80 innings:96 - 45 = 51The answer, in more than 100 words, is that Warren had more strikeouts in 80 innings than he had in 36 innings.

There are two correct statements regarding a 5 by 5 matrix with three eigenvalues, one of which has a three-dimensional eigenspace.

First, there must be at least two linearly independent eigenvectors associated with the eigenvalue that has a three-dimensional eigenspace. Second, the sum of the dimensions of the eigenspaces must be equal to the size of the matrix, which is 5 in this case.

To understand the first statement, recall that the dimension of an eigenspace is equal to the multiplicity of the associated eigenvalue, which is the number of times it appears as a root of the characteristic equation. Since one of the eigenvalues has a three-dimensional eigenspace, its multiplicity must be at least 3. This means there are at least 3 linearly independent eigenvectors associated with this eigenvalue, which is necessary to span a three-dimensional space. However, the sum of the multiplicities of all eigenvalues cannot exceed the size of the matrix, which is 5. Therefore, the remaining two eigenvalues must have a combined multiplicity of 2 at most, which implies that there are at most 2 linearly independent eigenvectors associated with each of them.

To understand the second statement, note that the sum of the dimensions of the eigenspaces is equal to the sum of the multiplicities of all eigenvalues. This follows from the fact that the eigenspaces associated with distinct eigenvalues are linearly independent. Since there are three distinct eigenvalues in this case, the sum of their multiplicities is at most 5, which means the sum of the dimensions of their eigenspaces is also at most 5. Since one of the eigenspaces has dimension 3, the sum of the dimensions of the other two eigenspaces must be at least 2, which means each of them has at least one linearly independent eigenvector.
