Answer: 2(u-3)(2u-3)

Step-by-step explanation:

4u²-18u +18           take out the greatest common factor, 2, all terms can be divided by 2

2(2u²-9u +9)         to factor, multiply the first and the last parts of the quadratic.  2(9)=18   Find 2 numbers that multiply to 18 but add to the middle number.  

-6 and -3  both multyiply to +18 but add to -9

Take those 2 numbers, -6 and -3, and replace the  middle term with those numbers

2(2u²-6u-3u +9)  we have not changed the equation, we have simply replaced the term and broke it up.  -9u = -6u-3u

2(2u²-6u-3u+9) now we "group" the first 2 terms and the last 2

2[(2u²-6u)(-3u +9)]    this is not your factor you must take out the greatest common factor from each of the groupings

2[2u(u-3)-3(u-3)]   if the parentheses are the same, then you've done a good job. the first factoring will be what is in your parentheses, the second will be what ever is left.

2(u-3)(2u-3)

Answer:

V = 30 in³

Step-by-step explanation:

the volume (V) of a pyramid is calculated as

V = \(\frac{1}{3}\) × B × h ( B is the area of the base and h the height ) , then

V = \(\frac{1}{3}\) × 6 × 15 = 2 × 15 = 30 in³

Answer:

The volume of the pyramid is 30 inches cube.

The base of the pyramid is an equilateral triangle with an area of 6 inches².  The height of the pyramid is 15 inches.

Therefore, the volume of the pyramid can be calculated as follows:

volume of the pyramid = 1 / 3 BH

where

B = base area

H = height of the pyramid

Therefore,

B = 6 inches²

H = 15 inches

Hence,

volume of the pyramid = 1 / 3 × 6 × 15

volume of the pyramid = 1 / 3 × 90

Therefore,

volume of the pyramid = 30 inches³

TRUE. The critical value of a hypothesis test is based on the researcher's selected level of significance.

The critical value of a hypothesis test is based on the researcher's selected level of significance. The level of significance represents the probability of rejecting a true null hypothesis, and it determines the critical value, which is the point beyond which we reject the null hypothesis. Therefore, the higher the level of significance, the lower the critical value, and the easier it is to reject the null hypothesis.
True, the critical value of a hypothesis test is based on the researcher's selected level of significance.

The derivative of F(x) is \(F'(x) = x^{(1/3)\).

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output.

To find the derivative of the given function F(x), we will apply the fundamental theorem of calculus and differentiate the integral with respect to x.

Let's compute F'(x):

F(x) = ∫[0 to x] \(t^{(1/3)} dt\)

To differentiate the integral with respect to x, we'll use the Leibniz integral rule:

F'(x) = d/dx ∫[0 to x] \(t^{(1/3)} dt\)

According to the Leibniz integral rule, we have to apply the chain rule to the upper limit of the integral.

\(F'(x) = x^{(1/3)} d(x)/dx - 0^{(1/3)} d(0)/dx\)   [applying the chain rule to the upper limit]

Since the upper limit of the integral is x, the derivative of x with respect to x is 1, and the derivative of 0 with respect to x is 0.

\(F'(x) = x^{(1/3)} (1) - 0^{(1/3)} (0)\)

\(F'(x) = x^{(1/3)\)

Therefore, the derivative of F(x) is \(F'(x) = x^{(1/3)\).

Answer:

x = 1/9

Step-by-step explanation:

8x + 2 = 3 - x

Add x to both sides.

9x + 2 = 3

Subtract 2 from both sides.

9x = 1

Divide both sides by 9.

x = 1/9

Answer:

x = 1/9

Step-by-step explanation:

We are given the equation:

8x + 2 = 3 - x

In order to solve for the variable x, we need to isolate it; in other words, we need to combine all the x terms and move everything else to the other side.

First, add x to both sides:

8x + x + 2 = 3

9x + 2 = 3

Now subtract 2 from both sides:

9x = 3 - 2 = 1

Divide both sides by 9:

x = 1/9

\(Scale= 1 : 2000\)

Required

Fill in the table

The scale implies that:

To fill in the gaps of actual measurements, we simply multiply the scale measurement by 2000

To fill in the gaps of scalar measurements, we simply divide the actual measurement by 2000

For the flag height, we have:

\(Scale\ Measurement = 13.2\ cm\)

Using the analysis above:

\(Actual = 2000 * 13.2\ cm\)

\(Actual = 26400\ cm\)

Convert to meters

\(Actual = 26400m/100\)

\(Actual = 264m\)

For the flag length, we have:

\(Actual\ Measurement = 396\ m\)

Using the analysis above:

\(Scale\ Measurement = 396\ m /2000\)

\(Scale\ Measurement = 0.198\ m\)

Convert to centimeters

\(Scale\ Measurement = 0.198\ cm * 100\)

\(Scale\ Measurement = 19.8\ cm\)

For the height of crescent moon, we have:

\(Actual\ Measurement = 99\ m\)

Using the analysis above:

\(Scale\ Measurement = 99\ m /2000\)

\(Scale\ Measurement = 0.0495\ m\)

Convert to centimeters

\(Scale\ Measurement = 0.0495\ cm * 100\)

C does not represent a function

Step-by-step explanation:

you find 2 for each y- coordinate. Whenever you have a reputation in number for y axis means its not a function

The y-intercept of the equation y = 2x + 3 is 3.

To find the y-intercept in an equation of slope, you need to understand the slope-intercept form of a linear equation, which is written as y = mx + b.

In this equation, 'm' represents the slope, and 'b' represents the y-intercept.

The y-intercept is the value of y when x is equal to zero, meaning it is the point where the line intersects the y-axis. To determine the y-intercept, set x = 0 in the equation and solve for y.

This will give you the y-coordinate of the point where the line crosses the y-axis.

For example, let's say you have the equation y = 2x + 3. To find the y-intercept, substitute x = 0 into the equation:

y = 2(0) + 3

y = 0 + 3

y = 3

Therefore, the y-intercept of the equation y = 2x + 3 is 3.

In summary, to find the y-intercept in an equation of slope, substitute x = 0 into the equation and solve for y. This will give you the y-coordinate where the line intersects the y-axis.

Answer:

Step-by-step explanation:

The explicit formula for the nth term (aₙ) of the given arithmetic sequence is aₙ = -7n + 34, where n represents the position of the term in the sequence.

To find the explicit formula for the nth term (aₙ) of the given arithmetic sequence, we need to identify the common difference (d) between consecutive terms.

From the given sequence: 27, 20, 13, 6, ...

We can observe that each term decreases by 7 to obtain the next term. Therefore, the common difference is -7.

Now, we can use the formula for the nth term of an arithmetic sequence:

aₙ = a₁ + (n - 1) * d

Where:

aₙ represents the nth term,

a₁ is the first term,

n is the position of the term,

d is a common difference.

In this case, the first term a₁ is 27 and the common difference d is -7.

Substituting the values into the formula, we have:

aₙ = 27 + (n - 1) * (-7)

Simplifying further, we get:

aₙ = 27 - 7n + 7

aₙ = -7n + 34

Therefore, the explicit formula for the nth term (aₙ) of the arithmetic sequence is aₙ = -7n + 34.

The difference quotient evaluated in x = 2 gives:

[ f(2 + h) - f(2)]/h = h + 9

So the last option is the correct one.

Here we know the function:

f(x) = x^2 + 5x + 6

And we want to find the difference quotient:

[ f(2 + h) - f(2)]/h

Let's evaluate the function:

f(2 + h) = (2 + h)^2 + 5*(2 + h) + 6

            = 2^2 + h^2 + 4h + 10 + 5h + 6

            = h^2 + 9h + 20

f(2) = 2^2 + 5*2 + 6

f(2) = 4 + 10 +  6 = 20

Then we have:

[ f(2 + h) - f(2)]/h

[h^2 + 9h + 20 - 20]/h

[h^2 + 9h ]/h

Taking the quotient we get:

[h^2 + 9h ]/h = h + 9

To calculate the probability that the sample mean IQ is greater than 115, we need to use the concept of sampling distribution and the central limit theorem.

Given:

Population mean (μ) = 112

Population standard deviation (σ) = 25

Sample size (n) = 300

The mean of the sampling distribution of the sample means (μx) will be the same as the population mean (μ) which is 112.

The standard deviation of the sampling distribution (σx) can be calculated using the formula:

σx = σ / √(n)

Plugging in the values:

σx = 25 / √(300)

≈ 1.443

Now, we can use the z-score formula to standardize the sample mean:

z = (x - μx) / σx

where x is the sample mean.

Plugging in the values:

z = (115 - 112) / 1.443

≈ 2.08

Next, we need to find the probability that the standardized sample mean (z) is greater than 2.08.

This can be done by looking up the z-score in the standard normal distribution table or by using a calculator or statistical software.

Using a standard normal distribution table or calculator, we find that the probability associated with a z-score of 2.08 is approximately 0.981.

x=60

Step-by-step explanation:

The numbers would be 60 and 12.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Let the numbers would be x and y

Given that the sum of the two numbers is 72

So x + y = 72

And two times the first number equals 10 times the second number.

So 2x = 10y

Divided by 2 into both sides of the equation,

⇒ x = 5y

⇒ 5y + y=72

⇒ 6y = 72

⇒ y = 12

Substitute the value of y = 12 in the equation x + y = 72,

⇒ x + y = 72

⇒ x + 12 = 72

⇒ x = 72 - 12

⇒ x = 60

So x = 60 and y = 12

The value of Erica's investment after 6 years is approximately $4,939.05.

To find the value of Erica's investment after 6 years, we can use the compound interest formula. The formula for compound interest is given as:

A = P\((1 + r/n)^(nt)\)

Where:

A is the final amount or value of the investment.

P is the initial principal or investment amount.

r is the annual interest rate (as a decimal).

n is the number of times the interest is compounded per year.

t is the number of years.

In this case, Erica's initial investment is $4000, the annual interest rate is 4% (or 0.04 as a decimal), and the investment is growing annually. Therefore, we have:

P = $4000

r = 0.04

n = 1 (since the interest is compounded annually)

t = 6 years

Plugging these values into the compound interest formula, we can calculate the final value of the investment:

A = $4000(1 + \(0.04/1)^(1*6)\)

A = $4000(1 + 0.04)^6

A = $4000(1.04)^6

Evaluating this expression, we find:

A ≈ $4,939.05

Therefore, the value of Erica's investment after 6 years is approximately $4,939.05.

This calculation assumes that no additional investments or withdrawals were made during the 6-year period and that the interest rate remains constant at 4% per year.
