Step-by-step explanation:

you don't know the meaning of

\(y = {h}^{ - 1} (x)\)

it means it is the inverse function to h(x).

the regular function assigns an y value to every x value.

the inverse function now turns this around and finds for a given y value the original x value.

so, the inverse function is easier understood, if we would write it

\(x = {h}^{ - 1} (y)\)

but just for formal reasons, we don't define functions this way but do it like above (x is the input, y the output value).

just, the understanding of an inverse function is a I just described it.

that means for the points, simply x and y values trade places.

the point (1, 9) turns into (9, 1) (it means 1 was the original x value when the original function delivered 9 a result).

and the point (3, 2) turns into (2, 3).

so, move the 2 green dots to these coordinates.

The value of the sides are;

x = 13

y = 13 √2

To determine the value of the identities, we have to note the know the trigonometric identities. They are;

From the information given, we have that;

Using the tangent identity;

tan θ = opposite/adjacent

substitute the values, we get

tan 45 = x/13

Latitude 36°30′ was designated by the Missouri Compromise of 1820 as the northern limit for the legalization of slavery in the western territories.

By Stephen A. Douglas's Kansas-Nebraska Act of 1854, the Missouri Compromise's prohibition on slavery in the former Louisiana Territory north of the parallel 36°30′ north had been essentially removed. Latitude 36°30′ was designated by the Missouri Compromise of 1820 as the northern limit for the legalization of slavery in the western territories.

The expansion of slavery into the western lands was addressed by the Missouri Compromise, the Compromise of 1850, and "Bleeding Kansas." The balance between "free" and "slave" states in the Union was a factor in each of them.

Slavery was proposed to be outlawed in the remaining Louisiana Territory above the 36° 30' latitude line in the Missouri Compromise. The Kansas-Nebraska Act of 1854 abolished this clause after it had been in effect for 34 years.

The parameters \(w_{1}\) and \(w_{2}\) are 0.625 and 0.9375, respectively.

The least square estimation is a method of estimating unknown parameters in a linear regression model.

The method involves finding the parameters of the regression equation such that the sum of the squares of the differences between the observed and predicted values is minimized.

The parameters of the regression equation can be found using the following formula:

$$\underline{w}=(X^{T}X)^{-1}X^{T}\underline{y}$$

where X is the matrix of input samples,

y is the vector of target output samples, and

w is the vector of parameters to be estimated.

The superscript T denotes the transpose of a matrix and the superscript -1 denotes the inverse of a matrix.

The regression equation is given by:

$$y=w_{1}x_{1}+w_{2}x_{2}$$

where \(w_{1}\) and \(w_{2}\) are the parameters to be estimated.

Using the above formula, we can find the values of \(w_{1}\) and \(w_{2}\) as follows:

$$\begin{bmatrix}w_{1}\\w_{2}\end{b matrix (X^{T}X)^{-1}X^{T}\underline{y}$$$$\begin{bmatrix}w_{1}\\w_{2}\end{bmatrix}=\begin{bmatrix}1 & 1 & 1 & 1\\2 & 3 & 4 & 5\end{bmatrix}^{T}\begin{bmatrix}1\\2\\3\\4\end{bmatrix}$$$$\begin{bmatrix}w_{1}\\w_{2}\end{bmatrix}=\begin{bmatrix}30 & 40\\40 & 54\end{bmatrix}^{-1}\begin{bmatrix}20\\70\end{bmatrix}$$$$\begin{bmatrix}w_{1}\\w_{2}\end{bmatrix}=\begin{bmatrix}0.625\\0.9375\end{bmatrix}$$

The average time Americans spend watching TV per day is reported to be approximately 300 minutes, following a normal distribution with a standard deviation of 26 minutes.

To address this question, we can use the provided information to describe the distribution of minutes per day spent watching TV by Americans.

Given that the distribution follows a normal distribution, we can assume that the data is symmetrically distributed around the mean. The mean of the distribution is given as 300 minutes.

The standard deviation, which measures the spread of the data, is stated as 26 minutes. This indicates that most people fall within one standard deviation of the mean.

Using the properties of a normal distribution, we can make various probabilistic statements. For example, approximately 68% of Americans would spend between 274 minutes (mean - 1 standard deviation) and 326 minutes (mean + 1 standard deviation) watching TV per day.

By understanding the characteristics of the normal distribution and the provided parameters (mean and standard deviation), we can analyze and make predictions about the amount of time Americans spend watching TV on a daily basis.

Let,

Weight of first paperbacks, x = 2/3 pounds

Weight of second paperbacks, y = 3/4 pounds

x + y = 179 (1)

2/3x + 3/4y = 128 (2)

Multiply (1) by 3 and (2) by -4

3x + 3y = 537

-4(2/3x) + -4(3/4y) = -512

3x + 3y = 537

-8/3x - 3y = -512

Add both equations to eliminate y

3x + (-8/3x) = 537 + (-512)

3x - 8/3x = 537 - 512

If the diagonals of a quadrilateral divide each other proportionally, it is a trapezium.

Let's consider a quadrilateral ABCD, where the diagonals AC and BD intersect at point E. If the diagonals divide each other proportionally, it means that AE/CE = BE/DE.

To prove that the quadrilateral is a trapezium, we need to show that one pair of opposite sides is parallel.

Using the proportionality condition, we can rewrite it as (AE/CE) = (BE/DE) = 1.

By the Converse of the Basic Proportionality Theorem, we know that if two lines are cut by a transversal such that corresponding angles are equal, then the lines are parallel. In this case, AE is parallel to CD, and BE is parallel to AD.

Therefore, we have shown that AB || CD, which is the definition of a trapezium.

If the diagonals of a quadrilateral divide each other proportionally, it can be concluded that the quadrilateral is a trapezium.

The area of trapezoid FGD is 12 square units.

To find the area of trapezoid FGD, we need to first determine the lengths of the bases (parallel sides) of the trapezoid. The bases are segments AB and CD. The coordinates of points A, B, C, and D are (-1,3), (9,3), (6,7), and (3,7) respectively.

The length of base AB can be calculated using the distance formula:

AB\(= \sqrt((x2 - x1)^2 + (y2 - y1)^2)\\= \sqrt((9 - (-1))^2 + (3 - 3)^2\\= \sqrt(10^2 + 0^2)\\= \sqrt(100)\\= 10\)

Similarly, the length of base CD can be calculated as:

CD = \(\sqrt((x2 - x1)^2 + (y2 - y1)^2)\\= \sqrt((3 - 6)^2 + (7 - 7)^2)\\= \sqrt((-3)^2 + 0^2)\\= \sqrt(9)\\= 3\)

Now, we can calculate the area of trapezoid FGD using the formula:

Area = (base1 + base2) * height / 2

The height of the trapezoid is the y-coordinate difference between points E and F (or G), which is 5 - 3 = 2 units.

Substituting the values into the formula:

Area = (10 + 3) * 2 / 2

= 13 * 2 / 2

= 13

The publication of three major books on race in chronological order, from earliest to most recent is:

Chronological order is the listing, description, or discussion of when events occurred in relation to time. Essentially, it is similar to looking at a chronology to see what happened initially and what happened after that. For example, if teachers asked their pupils to recount their first day of school, they would expect students to begin by waking up that morning and getting ready. If pupils begin from the time they enter the school, significant information is lost and the listener may become confused due to a lack of knowledge.

Helping pupils grasp what chronological order is and how to use the skill correctly can benefit students ranging from kindergarten to collegiate levels.

The value of the machine 7 years from now.

To determine the value of the machine 7 years from now, we can use the formula for exponential decay:

V(t) = V(0) * e^(-kt)

Where:

V(t) is the value of the machine at time t

V(0) is the initial value of the machine

k is the decay constant

t is the time in years

We are given that the machine was purchased 9 years ago for $77,000, so V(0) = $77,000. We also know that the current value of the machine is $35,000, so V(t) = $35,000.

We can plug in these values to find the decay constant:

$35,000 = $77,000 * e^(-k * 9)

Dividing both sides by $77,000:

e^(-k * 9) = $35,000 / $77,000

Taking the natural logarithm of both sides:

-ln(e^(-k * 9)) = ln($35,000 / $77,000)

Simplifying:

9k = ln($35,000 / $77,000)

Now we can solve for k:

k = ln($35,000 / $77,000) / 9

Now we can use this value of k to find the value of the machine 7 years from now:

V(7) = $77,000 * e^(-k * 7)

Substituting the value of k we found:

V(7) = $77,000 * e^(-ln($35,000 / $77,000) / 9 * 7)

Calculating this expression will give us the value of the machine 7 years from now.

The value of the machine 7 years from now, based on the exponential decay model, will be about $17960.33.

This question pertains to exponential decay. In mathematics, we often use the formula for exponential decay to analyze the decline of asset values over time. The formula is V(t) = V0 * e^(-kt), where V(t) is the value at time t, V0 is the initial value, k is the decay constant, and e is the base of natural logarithms (approximately equal to 2.71828).

Given that the initial value of the machine was $77000 and it is now worth $35000 after 9 years, we first solve for the decay constant k using the equation: 35000 = 77000 * e^(-9k). Solving for 'k', we find that k is approximated to 0.0613.

Now, to find the value of the machine 7 years from now (16 years total from the original purchase), we substitute these values into our formula, getting V(16) = 77000 * e^(-0.0613*16), which gives us a machine value of approx $17960.33, rounded to the nearest cent.

The values of sin 2t, cos 2t and tan 2t are as follows:

sin(2t) = (2√24)/25

cos(2t) = 119/25

tan(2t) = 2(√24) / 23

Given that sint= 1/5 , and t is in quadrant I.To find sin 2t, we know that,2 sin t cos t = sin (t + t)Or sin 2t = 2 sin t cos t

Now, sin t = 1/5 (given),And, cos t = √(1 - sin²t) = √(1 - 1/25) = √24/5. Thus, sin 2t = 2 sin t cos t= 2 (1/5) (√24/5) = 2√24/25 = (2√24)/25. This is the required value of sin 2t. Now, to find cos 2t, we use the following formula:

cos 2t = cos²t - sin²t

Here, we already know the value of sin t and cos t, and so we can directly substitute the values and get the answer.Cos 2t = cos²t - sin²t= [√(24/5)]² - (1/5)²= 24/5 - 1/25= (119/25)This is the required value of cos 2t. To find tan 2t, we use the following formula:

tan 2t = (2 tan t)/(1 - tan²t)

Here, we already know the value of sin t and cos t, and so we can directly substitute the values and get the answer.tan t = sin t/cos t = (1/5) / (√24/5) = 1/(√24) = (√24)/24tan²t = 24/576 = 1/24

Now, substituting these values in the formula for tan 2t, we get:

tan 2t = (2 tan t)/(1 - tan²t)= 2 [(√24)/24] / [1 - 1/24]= 2(√24) / 23

This is the required value of tan 2t. Hence, the values of sin 2t, cos 2t and tan 2t are as follows:

sin(2t) = (2√24)/25

cos(2t) = 119/25

Answer:

D, \(w\geq 23\)

Step-by-step explanation:

The length is 6 inches longer than it's width, therefore:

\(l=w+6\)

The area of the rectangle is AT LEAST 667 square inches, so:

\(lw\geq 667\)

Now, we have a system of two equations:

\(\left \{ {{l=w+6} \atop {lw\geq 667}} \right.\)

We want to isolate the width, so substitute the first equation into the second to eliminate the length.

\((w+6)w\geq 667\)

Simplify:

\(w^2+6w\geq 667\)

Since we now have a polynomial equation that needs to be factored, set the value of one side to 0.

\(w^2+6w-667\geq 0\)

Now factor the equation:

\((w-23)(w+29)\geq 0\)

Taking each factor individually, we find the following:

\(w\geq 23\\w\geq -29\)

Since a negative width doesn't make any sense, we can eliminate that solution, and we are left with the correct answer!
