Answer:

A = (1, 10)

B = (4,10)

C = (4, 14)

D = (1, 16)

Step-by-step explanation:

Okay, so first, we move, or translate the quadrilateral PQRS down -8 spaces on the graph, turning old points:

P (1, -2) = (1, -10)     Q (4, -2) = (4, - 10)     S (1, -8) = (1, -16)     and R (4, -6) = (4, -14)

Now, we need to rotate this new box into -x, y. So our new points are:

(1, -10) = (-1, 10)     (4, -10) = (-4, 10)     (1, -16) = (-1, 16)     and (4,-14) = (-4, 14)

Now we're reflecting off the y-axis, making our x change. So for our final points:

A(1, 10)   B (4,10)    D(1, 16)    and C(4, 14)

Hope this helps! Please check my math and comment wether this worked or not! :)

To determine the explicit rule for the nth term of the given geometric sequence 5, 20, 80, 320, 1,280, ..., use the formula:`an = a1 * r^(n - 1)`, where an represents the nth term of the sequence.`a1`represents the first term of the sequence.`r` represents the common ratio between terms of the sequence.

The given sequence is 5, 20, 80, 320, 1,280, ...Let's now apply the formula to find the explicit rule for the nth term of the given sequence.`an = a1 * r^(n - 1)`Where a1 = 5 (first term of the sequence)`r` can be found by dividing any term by the preceding term, as `r = (second term) / (first term)`In this case,`r = (20) / (5) = 4`

Substituting the values in the formula:`an = a1 * r^(n - 1)``an = 5 * 4^(n - 1)` Therefore, the explicit rule for the nth term of the given geometric sequence is `an = 5 * 4^(n - 1)`.You can use this formula to find the value of any term in the sequence, given its position (n) in the sequence.For example, to find the 150th term of the sequence, substitute n = 150 in the formula: `a150 = 5 * 4^(150 - 1)`. This simplifies to `a150 = 1.442 x 10^90`.

The clock's minute hand is longer than the hour hand.

We know that the face of a clock is divided into 12 equal parts, and the radius of the clock face is 6 inches. We also know that the hands of the clock will form a central angle. The accurate statements about the clock are:

The length of each hour's section is π inches, or 3.14 inches.

The central angle of each hour section is 30°.

The clock's minute hand is longer than the hour hand.

Since there are 12 divisions, 360°/12 = 30°. Therefore, the central angle of each hour section is 30°.

The length of each hour's section can be calculated as the circumference of the clock face (2πr) divided by 12. Therefore, the length of each hour's section is (2π × 6)/12 = π inches, or approximately 3.14 inches.

The clock's minute hand is longer than the hour hand because it needs to travel a greater distance in the same amount of time.

The minute hand travels 360° in 60 minutes, while the hour hand travels 360° in 12 hours. Therefore, the minute hand must be longer to cover more distance in the same amount of time.

Therefore, the accurate statements about the clock are:

The length of each hour's section is π inches, or 3.14 inches.

The central angle of each hour section is 30°.

We can conclude that we are 95% confident that the true proportion of American adults who believe in aliens lies between 0.63 and 0.81 is the answer.

In a survey conducted on an SRS of 200 American adults, 72% of them said they believed in aliens. We have to provide a 95% confidence interval for the percent of American adults who believe in aliens. A confidence interval is a range of values that estimates a population parameter with a specific level of confidence.

The formula for a confidence interval for a population proportion is: p ± zα/2  ×  √((p(1-p))/n) where, p is the sample proportion, zα/2 is the z-value for the level of confidence, and n is the sample size.

Here, p = 0.72, n = 200, α = 1 - 0.95 = 0.05/2 = 0.025 (for a 95% confidence interval), and zα/2 = 1.96 (from the z-table).

Now, let's plug in the values: p ± zα/2  ×  √((p(1-p))/n) = 0.72 ± 1.96 × √((0.72(1 - 0.72))/200)= 0.72 ± 0.0894

Thus, the 95% confidence interval for the percent of American adults who believe in aliens is (0.63, 0.81).

Therefore, we can conclude that we are 95% confident that the true proportion of American adults who believe in aliens lies between 0.63 and 0.81.

Given:

To determine whether the relation defines y as a function of x, we get the domain first.

Based on the given relation, when we plug in x=0, the value would be undefined. So the function domain is x<0 or x>0.

Hence, the interval notation is:

Answer:

x=6

Step-by-step explanation:

Basically you want to isolate x into a form x=... so you have to work your way backwards.

First, notice that there is an expression (x+3) that is multiplied by 3. Let's undo that. If we remove the 3, then the right hand side will also have to change. In fact, we can divide both sides by 3.

You then get (x+3) = 9.

Now, let's subtract 3 from both sides:

x+3 -3 = 9 -3

Which simplifies to x = 6.

So with the operations "divide left and right by the same" and "subtract the same left and right", you can simplify most equations.

Step-by-step explanation:

solving an equation is like finding out for a balance, why the contents of the 2 cups weigh the same.

to take away (or add) piece by piece the same weight from both sides to keep the balance, until you find the originally not obvious reason for the balance.

in our case e look for the value of x. everything else we know.

so, we try to sort between the types of terms (the ones with variables, the ones without variables, then maybe different variables if applicable and so on).

but we have to do it by keeping the balance.

so everything we change on one side, we also have change on the other.

3(x + 3) = 27

we could do now 2 different things.

we could multiply the bracket term and then see how to continue.

or we could divide both sides by 3 to get rid of the obscuring multiplication factor of the bracket term with the variable.

we still keep the variable on one side.

so, I suggest we do the second thing.

3(x + 3) = 27 | /3 both sides

x + 3 = 9

now we still have constant terms on both side.

let's get rid of the constants on the variable side.

how ? well, we need to subtract 3.

x + 3 = 9 | -3 on both sides

x = 6

hey, and we are finished !

x = 6 made the balance happen.

The other values of \(\( x \)\) when the same maximum value occurs when we add or subtract multiples of  \(\(\frac{14\pi}{15}\)\)  from the given value of \(\( x \)\).

Understanding the properties of the cosine function and how it relates to the given equation.

The cosine function oscillates between its maximum value of 1 and its minimum value of -1. The value of \(\(a\)\) in the equation \(\(y = a\cos(bx - c) + d\)\)determines the amplitude of the oscillation. In given equation, the coefficient 2 before \(\(\cos3(x - 30)\)\) indicates that the amplitude is 2.

The \(\(b\)\) value in the equation determines the period of the oscillation. The period, denoted as \(\(T\)\), is calculated using the formula

\(\(T = \frac{2\pi}{|b|}\).\)

In the equation,\(\(b = 3\)\), so the period of the cosine function is

\(\(T = \frac{2\pi}{3}\)\).

Given that the maximum occurs at\(\(x = 30\)\) degrees, the equation is of the form \(\(y = a\cos(bx)\)\). The maximum value of the cosine function is achieved when\(\(bx\)\) is a multiple of \(\(2\pi\)\).

When \(\(x = 30\)\), we have \(\(30b = 2\pi k\)\),

where \(k\) is an integer. Rearranging the equation,

\(\(b = \frac{2\pi k}{30}\).\)

Since \(\(b = 3\)\) , substitute it to solve for \(\(k\)\).

\(\(\frac{2\pi k}{30} = 3\)\)

Simplifying the equation, we get:

\(\(2\pi k = 90\)\)

Dividing both sides by \(\(2\pi\)\), we find:

\(\(k = \frac{90}{2\pi}\)\)

Approximating the value of \(\(\pi\) to 3.14\), we can calculate \(\(k\)\):

\(\(k = \frac{90}{2 \times 3.14} \approx 14.33\)\)

Since \(\(k\)\) must be an integer, the closest integer to 14.33 is 14. Therefore, when the same maximum value occurs, the value of \(\(x\)\)will be given by:

\(\(x = \frac{2\pi \times 14}{30}\)\)

Simplifying the equation:

\(\(x = \frac{28\pi}{30}\)\)

Reducing the fraction:

\(\(x = \frac{14\pi}{15}\)\)

So, when the same maximum value occurs, other values of \(\(x\)\) will be multiples of \(\(\frac{14\pi}{15}\)\).

Answer:

\(\frac{25}{56}\) pounds

Step-by-step explanation:

By using unitary method,

∵ 1 full tub of water weighs = \(3\frac{1}{8}\) pounds

∴ \(\frac{1}{7}\) of a water tub will weigh = \(3\frac{1}{8}\times \frac{1}{7}\)

                                               = \(\frac{(24+1)}{8}\times \frac{1}{7}\)

                                               = \(\frac{25}{56}\) pounds

Therefore, water filled in \(\frac{1}{7}\)th part of the tub will weigh \(\frac{25}{56}\) pounds.

The weight of the tub if filled up to 1/7 full is 25/56 pounds

Given:

If filled halfway:

= 1/7 × 3 1/8

= 1/7 × 25/8

Therefore, the 95% confidence interval for the population means rating for Miami is: (5.80, 7.72)

We can be 95% confident that the true mean rating for Miami International Airport falls within this interval.
To develop a 95% confidence interval for the population means rating for Miami International Airport, we need to follow these steps:

1. Calculate the sample mean (x) by adding up all the ratings and dividing by the sample size (n=50).
2. Calculate the sample standard deviation (s).
3. Use a t-distribution to find the t-score for a 95% confidence interval with (n-1) degrees of freedom.
4. Calculate the margin of error (ME) using the t-score, standard deviation, and sample size.
5. Add and subtract the margin of error from the sample mean to find the lower and upper limits of the confidence interval.

To calculate the 95% confidence interval, we need to use the formula:
CI = x ± Z' (s/√n)
Where:
x = sample mean
Z' = z-score for the desired confidence level (in this case, 95%, so

Z' = 1.96)
s = sample standard deviation
n = sample size

Step 1: Calculate the sample mean (x)
Sum of ratings = 346
Sample size (n) = 50
x = 346/50 = 6.92

Step 2: Calculate the sample standard deviation (s)
Variance = [(Sum of (rating - x)^2) / (n-1)] = 88.48
Standard deviation (s) = √(88.48) = 9.41

Step 3: Find the t-score
For a 95% confidence interval with 49 (n-1) degrees of freedom, the t-score is approximately 2.01.

Step 4: Calculate the margin of error (ME)
ME = t-score × (s / √n) = 2.01 × (9.41 / √50) = 2.01 × 1.33 = 2.67

Step 5: Find the confidence interval
Lower limit: x - ME = 6.92 - 2.67 = 5.80
Upper limit: x + ME = 6.92 + 2.67 = 7.72

Thus, the 95% confidence interval for the population mean rating for Miami International Airport is approximately

Answer:

\( 3^9 \)

Step-by-step explanation:

\( 3^8 \times 3 = 3^8 \times 3^1 = 3^{8 + 1} = 3^9 \)

To find a function given its derivative and an initial condition, we integrate the derivative and solve for the constant using the given condition. Example: \(f(x) = 14\sqrt{x} + 12\)  satisfies  \(f'(x) = 7/ \sqrt{x}\)  and f(9) = 54.

The function f(x) can be found by integrating f'(x) with respect to x. Given \(f'(x) = 7/\sqrt{x}\), we can integrate it to obtain \(f(x) = 14\sqrt{x} + C\) , where C is an arbitrary constant.

To determine the value of C, we use the initial condition f(9) = 54, which gives us:

\(54 = 14\sqrt{9} + C\)

54 = 42 + C

C = 12

Substituting C into the expression for f(x), we get the final solution:

\(f(x) = 14\sqrt{x} + 12\)

Therefore, the function f(x) that satisfies \(f'(x) = 7/\sqrt{x}\) and f(9) = 54 is \(f(x) = 14\sqrt{x} + 12.\)

In summary, we can find a function given its derivative and an initial condition by integrating the derivative and solving for the arbitrary constant using the given condition. In this case, we found the function \(f(x) = 14\sqrt{x} + 12\) that satisfies \(f'(x) = 7/\sqrt{x}\) and f(9) = 54.

XY = 39 ft

XZ = 39 ft

Step-by-step explanation:

     If we rotate the triangle 90° to the right we can see that the congruent angles are now on the bottom, making it the "more commonly seen isosceles triangle" we know.

     This means that the two legs will be congruent to each other, so we can set them equal and solve for n:

(9n + 12) = (15n - 6)

9n + 12 = 15n - 6

9n + 18 = 15n

18 = 6n

6n = 18

n = 3

     Now we can plug this value of n (3) into one of the expressions to solve for the legs. Since they will be the same length we only need to do one, but I will do both to make sure my work is as correct as possible:
