x is 27.6907 units

The inverse of the function f(x) = 3(x - 4)² + 5 is f^-1(x) = √[(x - 5)/3] + 4

A function is said to have an inverse if it is both one-to-one and onto

For the function f(x) = 3(x - 4)² + 5

we replace f(x) with y and make x the subject to arrive at the inverse f^-1(x) as follows;

y = 3(x - 4)² + 5

y - 5 = 3(x - 4)² + 5 - 5 {subtract 5 from both sides}

(y - 5)/3 = [3(x - 4)²]/3 {divide through by 3}

also;

(x - 4)² = (y - 5)/3

x - 4 = √[(y - 5)/3] {square root of both sides}

x - 4 + 4 = √[(y - 5)/3] + 4

x = √[(y - 5)/3] + 4

so,

y = √[(x - 5)/3] + 4 and

f^-1(x) = √[( - 5)/3] + 4

Hence, the inverse of the function f is derived by interchanging the value of x for y and vice versa, that is f^-1(x) = √[(x - 5)/3] + 4.

Step-by-step explanation:

let the 2 numbers be x and x + 4 as their deference is 4.

their sum = 50

now,

→ x + x + 4 = 50

→ 2x + 4 = 50

→ 2x = 50 - 4 = 46

→ x = 46/2 = 23

therefore two numbers are,

x = 23

x + 4 = 23 + 4 = 27

hope this answer helps you dear...take care and may u have a great day ahead!

Step-by-step explanation:

x + y = 50

x - y = 4

x = y + 4

let's use that as substitute in the first equation

y + 4 + y = 50

2y = 46

y = 46/2 = 23

=>

x = y + 4 = 23 + 4 = 27

the 2 numbers are 23 and 27.

A matrix consisting entirely of zeros is called a zero matrix, or an all-zero matrix.

It is denoted with the symbol O and can be written in a matrix form, such as O = [0 0 0 0] where the number of columns and rows depends on the size of the matrix. A zero matrix is a matrix which has all its elements equal to zero. It has a number of special properties that make it useful in linear algebra. For instance, the sum of any two zero matrices is a zero matrix, and any scalar multiple of a zero matrix is a zero matrix. Additionally, the product of two zero matrices is a zero matrix, and the product of a zero matrix and an identity matrix is a zero matrix. These properties make it useful in solving systems of linear equations where all the coefficients are zero. Finally, the inverse of a zero matrix does not exist since its determinant is zero.

Based on the scatter plot for this data, we can logically deduce that the association between them is a positive association.

A scatter plot can be defined as a type of graph which is used to graphically represent the values of two (2) variables, with the resulting points showing any association (correlation) between the data set.

Based on the scatter plot for this data, we can deduce that the association between them is a positive association because the price and customer rating increases together.

An example of a data point which would affect the appropriateness of using a linear regression model to fit all the data is car price of $4,601 and customer rating of 100.

An example of a car that is cost effective and rated highly by customers is the one with a customer rating of 100 and sold at $3,500.

The points (–2, 8) and (2, –8) are reflections of each other across both axes. This can be seen by taking their coordinates and plugging them into the reflection formula, which is (x, y) → (–x, –y).

When we plug in the coordinates for the first point, we get (–2, 8) → (–(–2), –(8)) = (2, –8). This is the coordinates of the second point, so they are reflections of each other.

The points (–7, –1) and (–7, 1) are also reflections of each other across both axes. Using the same reflection formula, we get (–7, –1) → (–(–7), –(–1)) = (7, 1), which are the coordinates of the second point.

The points (5, –6) and (–5, –6) are reflections of each other across both axes. Applying the reflection formula, we get (5, –6) → (–(5), –(–6)) = (–5, 6), which are the coordinates of the second point.

Finally, the points (4, –3) and (–3, 4) are reflections of each other across both axes. Using the reflection formula, we get (4, –3) → (–(4), –(–3)) = (–4, 3), which are the coordinates of the second point.

The quadratic inequality defined on the graph is given as follows:

y ≥ 2/3(x + 3)² - 24.

The coordinates of the vertex of the quadratic function are given as follows:

(-3, -24).

Hence the quadratic function is given as follows:

y = a(x + 3)² - 24.

In which a is the leading coefficient.

When x = 3, y = 0, hence the leading coefficient a is obtained as follows:

0 = a(3 + 3)² - 24

36a = 24

a = 24/36

a = 2/3.

Hence:

y = 2/3(x + 3)² - 24.

The quadratic function has a solid curve, and the values above it are pained, hence the inequality is given as follows:

To survey 120 guests for assessing their satisfaction, a hotel with 30 floors and 40 rooms per floor can use a systematic random sampling approach. By randomly selecting 120 rooms from the total of 1,200 rooms, the survey can include a representative sample of guests.

To conduct the survey, the hotel can implement a systematic random sampling technique. With 30 floors and 40 rooms per floor, the hotel has a total of 30 * 40 = 1,200 rooms. The manager can randomly select 120 rooms from this pool of 1,200 rooms to ensure a representative sample of guests.
To achieve proportionality in the sample, the hotel can select rooms proportionally from both the water-facing and golf course-facing sides. For example, if half of the rooms face the water and the other half face the golf course, the survey can include 60 water-facing rooms and 60 golf course-facing rooms.
Once the rooms are selected, the hotel staff can contact the guests who stayed in those rooms during the convention and request their participation in the survey. The survey questions can cover various aspects of their stay, such as amenities, cleanliness, customer service, and overall satisfaction.
By gathering feedback from the guests, the hotel can gain valuable insights to identify areas for improvement and enhance overall guest satisfaction.

Answer:

the angle closest to the 40degree angle is a right angle, so it is 90 degrees. The one with two lines is 50 degrees, and the farthest angle is 40 degrees

Step-by-step explanation:

A square symbol over an angle means it is a right angle, so it will always equal 90 degrees.

The already labeled angle (40 degrees) is equal to the farthest angle.

Once you have two angles, you can find the third angle by simply subracting the two from 180 like this:

180 - 90 - 40 = 50 degrees.

Step-by-step explanation:

If the number of t-shirts is between 0 and 10, the cost is:

If the number of t-shirts is greater than 50, the cost is:

y = 3 + 15x

Step-by-step explanation:

The derivative of the function g(x) = (x² - x + 1\()^1^0\) * (tan(x))³ is g'(x) = 10(x² - x + 1)⁹ * (2x - 1) * (tan(x))³ + 3(x² - x + 1\()^1^0\) * (tan(x))² * sec²(x).

To find the derivative of the given function g(x), we can apply the product rule and the chain rule. Let's break down the function into its constituent parts: f(x) = (x² - x + 1\()^1^0\) and h(x) = (tan(x))³.

Using the product rule, the derivative of g(x) can be calculated as g'(x) = f'(x) * h(x) + f(x) * h'(x).

First, let's find f'(x). We have f(x) = (x² - x + 1\()^1^0\), which is a composite function. Applying the chain rule, f'(x) = 10(x² - x + 1\()^9\) * (2x - 1).

Next, let's determine h'(x). We have h(x) = (tan(x))³. Applying the chain rule, h'(x) = 3(tan(x))² * sec²(x).

Now, we substitute these derivatives back into the product rule formula:

g'(x) = f'(x) * h(x) + f(x) * h'(x)

       = 10(x² - x + 1)² * (2x - 1) * (tan(x))³ + 3(x² - x + 1\()^1^0\)* (tan(x))² * sec²(x).

In summary, the derivative of the function g(x) = (x² - x + 1\()^1^0\) * (tan(x))³ is g'(x) = 10(x² - x + 1)⁹  * (2x - 1) * (tan(x))³ + 3(x² - x + 1\()^1^0\) * (tan(x))² * sec²(x).
