The answer is: (x-3)(x-1)(x+2)

Because the first term is x^3, it means that there must be 3 independent x's multiplying by each other. From there you just have to est what numbers to pair them with. If that doesn't make sense let me explain more:If you have x^2 it will be:(x + y) (x + z) If you have x^3 it will be: (x + y) (x + z) (x + g) If you have x^4 it will be: (x + y) (x + z) (x + g) (x + f) etc; now all you have to do after you pick which one it matches with, it just find what the value of y, z, and g are through trial and error. I am not showing all my trial and error because it is long to type out, easier to just explain the process.

Answer:

\({x}^{2} - 10x + 25\)

Step-by-step explanation:

For this problem, we can break the equation into (x - 5) use FOIL. First, Outer, Inner, Last.

(x - 5) (x - 5)

First, multiply the two Xs together.

X * X =

\( {x}^{2} \)

Now, the outer numbers and values.

X * -5 =

\( - 5x\)

Then, it's the inner numbers and values.

-5 * x =

\( - 5x\)

Finally, multiply the last numbers.

-5 * -5 =

\( 25\)

Now that we have multiplied all of the values, we can put the answers from FOIL together.

\( {x}^{2} - 5x - 5x + 25\)

Now, add any like terms.

\( - 5x - 5x = - 10x\)

The answer is

\( {x}^{2} - 10x + 25\)

True. Data Envelopment Analysis (DEA) is best used in an environment of low diverges and high complexity. In such situations, DEA can effectively analyze and compare the efficiency of decision-making units, even when dealing with multiple inputs and outputs.

Data Envelopment Analysis (DEA) is a method used to measure the efficiency of decision-making units. It works by analyzing a set of inputs and outputs to determine the relative efficiency of each unit. DEA is best suited for situations where there is low diverges among the units being analyzed, meaning they are all operating under similar conditions. Additionally, DEA is most effective in situations of high complexity, where there are multiple inputs and outputs that need to be considered. Therefore, the statement that DEA is best used in an environment of low divergence and high complexity is true.

The company's WACC is 9.95%. This implies that the company must generate a return of at least 9.95% on its investments to cover its cost of capital.

WACC (Weighted Average Cost of Capital) is a measurement used to determine a company's cost of capital. It is calculated as a weighted average of the costs of equity and debt, considering the company's capital structure. The formula for WACC is:

WACC = (E / V x Re) + [(D / V x Rd) x (1 - T)]

Where:

E = Market value of the company's equity

D = Market value of the company's debt

V = Total value of the company (equity + debt)

Re = Cost of equity

Rd = Pretax cost of debt

T = Tax rate

Given the following values:

Debt-equity ratio = 0.55

Cost of equity (Re) = 15.4%

Pretax cost of debt (Rd) = 7.8%

Tax rate = 32%

We can calculate the after-tax cost of debt, Rd, by multiplying the pretax cost of debt with (1 - tax rate). Thus,

Rd = 7.8% x (1 - 32%) = 5.292%

Now, we can substitute the values into the WACC formula:

WACC = [(E / V x Re) + (D / V x Rd) x (1 - T)]

WACC = [(1 / 1.55 x 15.4%) + (0.55 / 1.55 x 5.292%) x (1 - 32%)]

WACC = 9.95%

Therefore, the company's WACC is 9.95%. This implies that the company must generate a return of at least 9.95% on its investments to cover its cost of capital.

Answer:

The radius is given, so the radius is = 10

The radius is doubled to be a diameter, so (10 + 10) = 20 is your diameter

And to solve for circumference, your formula is;

C = 2πr

Where 'r' represents the radius, and 'π'(pi) is 22/7 or 3.14.

Plug in your values:-

C = 2πr

C = 2(3.14) x 10

C = 6.28 x 10

C = 62.8, so your circumference is 62.8.

2.

Your radius is half of your diameter, so,

D/2 = R

D = diameter

R = Radius

49/2 = 24.5 is your radius.

Your diameter is given, so the diameter is 49.

Use the formula we applied for circumference in our other problem;

C = 2πr

C = 2(3.14) x 24.5

C = 6.28 x 24.5

C = 153.86, so 153.86 is your circumference.

Answer:

2x/5 =16

=> 2x= 16×5= 80

=> X= 40 answer

Answer:

E= 36 D=102 F=42

Step-by-step explanation:

E= 36 because of the vertical angles theorem, d =102 because of vertical angles theorem, and finally we have f = 42 because all these angles form a straight angle/line which adds up to 180. So before we knew that d=102 and e=36 so we can add those up and we get 138. Then we subtract 132 from the measure of a straight angle (180 degrees), to get f. SO 180-132 =f=42

The four points on the lemniscate where the tangent is horizontal are (0, ±a/sqrt(2)) and (±sqrt(a^2 - x^2), ±sqrt(a^2 - x^2)), where x is a solution of the equation x(x^2 + y^2 - 2a^2) = 0

Explanation: The lemniscate is given by the equation (x^2 + y^2)^2 = 2a^2(x^2 - y^2), where a is a positive constant. To find the points on the lemniscate where the tangent is horizontal, we differentiate this equation with respect to x:

d/dx [(x^2 + y^2)^2] = d/dx [2a^2(x^2 - y^2)]

2(x^2 + y^2)(2x + 2y dy/dx) = 4a^2x

To find the values of x where the tangent is horizontal, we set the derivative dy/dx equal to zero, since a horizontal tangent has zero slope. This gives:

2(x^2 + y^2)(2x) = 4a^2x

(x^2 + y^2)(2x) = 2a^2x

x(x^2 + y^2 - 2a^2) = 0

Thus, we have two possible values of x: x = 0 and x^2 + y^2 = 2a^2. To obtain the corresponding values of y, we substitute these values of x into the equation of the lemniscate:

When x = 0, we have y = ±a/sqrt(2), corresponding to the two points (0, ±a/sqrt(2)) on the lemniscate where the tangent is horizontal.

When x^2 + y^2 = 2a^2, we have y = ±sqrt(2a^2 - x^2), corresponding to the two pairs of points on the lemniscate where the tangent is horizontal: (±sqrt(a^2 - x^2), sqrt(a^2 - x^2)) and (±sqrt(a^2 - x^2), -sqrt(a^2 - x^2)).

Therefore, the four points on the lemniscate where the tangent is horizontal are (0, ±a/sqrt(2)) and (±sqrt(a^2 - x^2), ±sqrt(a^2 - x^2)), where x is a solution of the equation x(x^2 + y^2 - 2a^2) = 0.

The mover is communicating that the weight of the table and 4 chairs combined, represented as t+4C, is greater than or equal to 100 pounds.

The expression t+4C represents the total weight of the table and 4 chairs. The mover's invoice states that this total weight is greater than or equal to 100 pounds, which means that the combined weight of the table and chairs is at least 100 pounds. Therefore, the correct answer is D, "The table and 4 chairs weigh at least 100 pounds."

To solve this mathematically, we can use algebraic inequalities. The inequality t+4C >_ 100 can be rearranged as t >_ 100-4C. This means that the weight of the table t must be greater than or equal to 100 minus four times the weight of a single chair C.

If each chair weighs less than 25 pounds, then the total weight of the table and 4 chairs combined will be at least 100 pounds. So D is correct answer.

Because studies used in a meta-analysis have typically used different statistical tests, a statistic called effect size is used to put all the results into a common scale.

A meta-analysis is a statistical approach used to synthesize the results of several studies. It is a quantitative study of studies. In other words, it is a method that uses statistical analysis to incorporate the results of multiple clinical studies, which helps to obtain a more precise and reliable estimate of the impact of the intervention.

Effect size is used to combine all the results of the different studies into a common scale because each study might use a different statistical test that is not directly comparable to other studies.What is effect size?Effect size is a numerical value that describes the magnitude of the difference between two groups in a study. It allows researchers to compare the findings from different studies that might use different measurement instruments.

A large effect size implies a significant difference between the two groups in a study. Conversely, a small effect size indicates that there is no meaningful difference between the groups. Effect size is calculated as the standardized difference between the means of two groups divided by their standard deviation (Cohen’s d).

Step-by-step explanation:

To find f'(a), the derivative of f(x) at the value a, we need to differentiate the function f(x) = 5/2x + 3 with respect to x using the power rule for derivatives.The equation of the tangent line is: 5x - 2y + 21 = 0.

The power rule states that if we have a function of the form f(x) = ax^n, where a and n are constants, then the derivative f'(x) is given by f'(x) = anx^(n-1).

Applying the power rule to f(x) = 5/2x + 3, we have:

f'(x) = (5/2) * 1x^(1-1)

= (5/2) * x^0

= (5/2) * 1

= 5/2

Therefore, f'(a) = 5/2.

b. To determine the equation of the line tangent to the graph of f at (a, f(a)), we use the point-slope form of a linear equation.

The equation of the tangent line is given by:

y - f(a) = f'(a) * (x - a)

Substituting f'(a) = 5/2 and a = 3, we have:

y - f(3) = (5/2) * (x - 3)

To find f(3), we substitute x = 3 into the original function:

f(3) = (5/2) * 3 + 3

= 15/2 + 3

= 21/2

Therefore, the equation of the tangent line at (a, f(a)) for a = 3 is:

y - (21/2) = (5/2) * (x - 3)

Simplifying, we get:

y - 21/2 = (5/2)x - 15/2

Bringing like terms to one side, we have:

(5/2)x - y + 21/2 = 0

Hence, the equation of the tangent line is:

5x - 2y + 21 = 0.

Answer: To find the percentage of people with an IQ score less than 117, we need to calculate the z-score first. The z-score measures how many standard deviations an individual score is from the mean in a normal distribution.

The z-score formula is given by:

z = (x - μ) / σ

Where:

Let's calculate the z-score:

Now, we need to find the percentage of people with a z-score less than 1.1333. We can look up this value in the standard normal distribution table (also known as the Z-table) or use statistical software/tools.

Using the Z-table, we find that the percentage of people with a z-score less than 1.1333 is approximately 0.8708, or 87.08% (rounded to the nearest hundredth).

Therefore, approximately 87.1% of people have an IQ score less than 117.
