The mapping of the function f(x) given as 3x⁴ - 4x³ + 3x² - 5x - 3 is define at; -3, f(-3) = 390 and at 4, f(4) = 537

A function is a rule that defines a relationship between one variable. It is the mapping whose codomain is the set of real numbers

For x = -3;

f(-3) = 3(-3)⁴ - 4(-3)³ + 3(-3)² - 5(-3) - 3

f(-3) = 3(81) + 4(27) + 3(9) + 15 - 3

f(-3) = 243 + 108 + 27 + 15 - 3

f(-3) = 390

For x = 4;

f(4) = 3(4)⁴ - 4(4)³ + 3(4)² - 5(4) - 3

f(4) = 3(256) - 4(64) + 3(16) - 20 - 3

f(4) = 768 - 256 + 48 - 20 - 3

f(4) = 537

Therefore, for the mapping of the function f(x) = 3x⁴ - 4x³ + 3x² - 5x - 3 for the values of x: -3 and 4 we have the results 390 and 537.

1) According to Denis' article "The Definition of Neotraditionism," his encounter with a painting by Maurice Denis himself, which featured a landscape that was "no longer a transcription of nature, but a creation" (Denis, 1914), influenced him to write the first non-objective statement.

This painting by Denis challenged the traditional notions of art as mere representation of nature, and instead presented a new idea of art as a creative act in its own right.

2) In his book "Concerning the Spiritual in Art," Kandinsky expressed his belief that art should go beyond mere representation of the physical world and instead aim to express the spiritual and emotional aspects of human experience. He wrote that "the artist must be blind to distinction between 'recognized' or 'unrecognized' conventions of form, deaf to the transitory teaching and demands of his particular age.

He must watch only the trend of the inner need, and hearken to its words alone" (Kandinsky, 1977, p. 8). This suggests that Kandinsky was motivated by a desire to break away from the conventional artistic norms of his time and create something that was more true to his own personal vision and inner creative impulses.

3) In Part II, About Painting, VI: The Language of Form and Color of "Concerning the Spiritual in Art," Kandinsky wrote: "Color is a power which directly influences the soul. Color is the keyboard, the eyes are the hammers, the soul is the piano with many strings. The artist is the hand that plays, touching one key or another purposively, to cause vibrations in the soul" (Kandinsky, 1977, p. 72).

An exponential equation that best fit the data above is [tex]y = 535.02(1.15)^x[/tex]

a = 535.02

b = 1.15.

In this scenario, the x-values (x) would be plotted on the x-axis of the scatter plot while the y-values (y) would be plotted on the x-axis of the scatter plot.

By critically observing the scatter plot (see attachment) which models the relationship between the x-values (x) and y-values (y), the exponential equation and the correlation coefficient are given by:

[tex]y = 535.02(1.15)^x[/tex]

Correlation coefficient, r = 0.9973006 ≈ 1.0

In conclusion, we can logically deduce that there is a strong correlation between the data because the correlation coefficient (r) is is greater than 0.7;

There will be no sugar left after the transfer.

Given are two containers in the shape of a rectangular prism and the second one is a composite solid of rectangular prism and a triangular prism,

We need to compare the volume of both prisms,

For the volume of the composite solid we will add the volume of both solids = 1/2 × base area × height + length × width × height

= 1/2 × 300 × 8 + 12 × 12 × 25

= 1200 + 3600

= 4800 cm³

Now the volume of the old container (rectangular prism - the blue one) = length × width × height = 30 × 20 × 8 = 4800 cm³

Since the volume of both old and new container is same, so there will be no sugar left after the transfer.

A = (x + 17)²- 289

d) The vertex of the parabola is (-17, -289).

The x-intercepts can be found by setting A = 0:

(x + 17)² - 289 = 0

(x + 17)² = 289

x + 17 = ±17

x = -34, 0 (x-intercepts)

The y-intercept is found by setting x = 0:

The student's chances of answering all five questions correctly are 7/64.

This is an example of a binomial distribution, where each question has a probability of 1/2 of being answered correctly and there are 8 independent trials.

The probability mass function for a binomial distribution is:

P(X = k) = (n choose k) * p^k * (1-p)^(n-k)

where n is the number of trials, p is the probability of success, and k is the number of successes.

In this case, n = 8, p = 1/2, and we want to find P(X = 5).

P(X = 5) = (8 choose 5) * (1/2)^5 * (1/2)^(8-5)

P(X = 5) = (8 choose 5) * (1/2)^8

Using the formula for combinations, (n choose k) = n! / (k! * (n-k)!) we get:

P(X = 5) = (8! / (5! * 3!)) * (1/2)^8

P(X = 5) = 56 * 1/256

P(X = 5) = 7/64

Answer:

So 98 adult tickets were sold.

Step-by-step explanation:

Let's use a system of equations to solve the problem.

Let x be the number of child tickets sold and y be the number of adult tickets sold. Then we have:

x + y = 176 (equation 1)

5.10x + 8.20y = 1201.40 (equation 2)

We can solve for x by isolating y in equation 1 and substituting into equation 2:

y = 176 - x (from equation 1)

5.10x + 8.20(176 - x) = 1201.40 (substitute into equation 2)

5.10x + 1443.20 - 8.20x = 1201.40

-3.10x = -241.80

x = 78

Therefore, 78 child tickets were sold that day. We can find the number of adult tickets by substituting x into equation 1:

78 + y = 176

y = 98

So 98 adult tickets were sold.

The axis of symmetry of the given quadratic function f(x) = -(x - 2)(x + 4) is x = -1.

Given the function in the question:

f(x) = -(x - 2)(x + 4)

To find the axis of symmetry, first expand  quadratic function f(x) = -(x - 2)(x + 4).

f(x) = -(x - 2)(x + 4)

f(x) = (-x + 2)(x + 4)

f(x) = -x(x + 4) + 2( x + 4 )

f(x) = -x² - 4x + 2x + 8

Collect and add like terms

f(x) = -x² - 2x + 8

To find the axis of symmetry, we can use the formula:

x = -b/2a

Where a = -1 and b = -2.

Substituting these values, we get:

x = -(-2) / 2(-1)

Simplify

x = 2 / -2

x = -1

the total number of posts needed is, 56

Since, we know that the area of the horse corral is 10,000 square feet.

So, it is a square corral, we can find the length of each side by taking the square root of the area, which is 100 feet.

Now, For the total number of posts needed, we need to calculate the perimeter of the corral.

Since there are four sides of equal length, the perimeter of the corral is 4 times the length of one side.

Therefore, the total perimeter is 400 feet.

Now, we need to find the number of posts needed.

We know that each post is placed 10 feet apart along the sides of the corral.

Since there are 4 sides, we need 3 intervals of 10 ft between each post, which gives us a total of 4 posts for every 30 feet of fencing.

Therefore, the total number of posts needed is,

= (400 / 30) x 4 + 4

= 56 posts.

Recall that in a circle, the measure of an intercepted arc is always the same or equal to the measure of the central angle it subtends.

Therefore, we have:

16. m(MN) = 72° (based on the vertical angles and inscribed angle theorems).

17. arc NQR is an half circle, therefore:

m(NQR) = 180°

18. m(NQ) = 180 - 72 = 108°

19. m(MRP) = 180 + (180 - 72 - 95)

m(MRP) = 193°

20. m(QR) = 72°

21. m(MR) = 180 - 72 = 108°

22. m(QMR) = 360 - 72

m(QMR) = 288°

23. m(PQ) = 180 - 72 - 95

m(PQ) = 13°

The inverse of function f(x) when f(x) = -2 is f¯¹(x) = 2x + 3.So, the correct option is D.

To find the inverse of a function, we switch the x and y variables and solve for y. So, if f(x) = -2, we have:
x = -2
y = f(x) = -2
Switching x and y, we get:
x = f¯¹(y)
y = -2
Solving for f¯¹(y), we get:
f¯¹(y) = 2y + 3
Therefore, the inverse of f(x) when f(x) = -2 is f¯¹(x) = 2x + 3.
To find the inverse of a function, we need to swap the input (x) and output (f(x)), and then solve for the new input. Given f(x) = -2, let's find the inverse:

Answer:

  8.68 cm²

Step-by-step explanation:

You want the increase in surface area of a box with length and width 13 cm and 8.7 cm when the height is increased from 30 cm by 0.2 cm.

The increase in area is effectively the lateral area of the prism whose length and width are the same, but whose height is 0.2 cm. That is ...

  A = Ph = 2(L+W)h

  A = 2(13 cm +8.7 cm)(0.2 cm) = 8.68 cm²

The surface area increases by 8.68 cm².

We can find the total area of the box with the different dimensions, then subtract the original area from the increased area.

  A = 2(LW +H(L+W))

  A1 = 2(13·8.7 +30(13 +8.7)) = 1528.2 cm²

  A2 = 2(13·8.7 +30.2(13 +8.7)) = 1536.88 cm²

The increase in area is 1536.88 -1528.2 = 8.68 cm².

We prefer the first solution, as it requires a lot less arithmetic.
