Answer:

vertex is (6, -11)

Step-by-step explanation:

Given equation
f(x) = x² - 12x + 25

is that of an upward-facing parabola(since the coefficient of x² is positive).

The vertex will be at a minimum and its x-coordinate can be found by finding the first derivative of f(x), setting it equal to zero and solving for x

f'(x) = d/dx(x² - 12x + 25)

= 2x - 12

f'(x) = 0 ==> 2x - 12 = 0

2x = 12

x = 6

Substitute x = 6 in f(x) to get

f(6) = 6² - 12(6) + 25

= 36 - 72 + 25

= -11

So the vertex is at (6, -11)

Answer: 112.5

Step-by-step explanation: When line AB and CD intersect at point E, angle AEC equals BED so you set them equal to each other and find what x is. 5x -20 = x + 50, solving for x, which gives you 17.5. Finding x will tell you what AEC and BED by plugging it in which is 67.5. Angle BED and BEC are supplementary angles which adds up to 180 degrees. So to find angle CEB, subtract 67.5 from 180 and you get 112.5 degrees.

Step-by-step explanation:

No real number when multiplied with zero makes one.

Answer:

Zero has no reciprocal

Step-by-step explanation:

The reciprocal of a number is what you get when you flip the numerator and the denominator of a number. For instance, with the number 5, it can be rewritten as 5/1. The reciprocal of this would therefore be 1/5. For 0, it can also be rewritten as 0/1. However, if you take the reciprocal of this, you get 1/0, which is undefined. Therefore, zero has no reciprocal.

The third one :

1) Functonal

2) Hedonic

The functional need for touch (NFTs) refers to individuals using touch to evaluate products, while the hedonic need for touch (NFTs) refers to individuals touching things because they find the tactile sensation pleasurable.

The functional need for touch (NFTs) is rooted in the practical aspect of touch. It pertains to individuals utilizing the sense of touch to evaluate products. When evaluating products, people often rely on tactile feedback to assess qualities such as texture, material, weight, and durability.

On the other hand, the hedonic need for touch (NFTs) is driven by the pleasurable sensation of touching objects.

Some individuals simply enjoy the tactile experience itself, finding pleasure in the sensation of running their fingers over different surfaces, textures, or shapes.

This pleasure-seeking aspect of touch can be soothing, comforting, or even arousing for some people. It can range from appreciating the smoothness of a polished stone to the satisfying feedback of pressing a button on a mechanical keyboard.

Both the functional and hedonic aspects of touch play a significant role in human interactions with the physical world, influencing consumer behaviors, preferences, and overall sensory experiences.

The probability of having a 5-card hand that is a flush or royal flush is 0.00196

Probability: Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

Flush, straight flush, and royal flush probabilities are calculated as follows: 5148/2598960≅0.00198

A flush's likelihood (while eliminating straight and royal flushes) is 5108/2598960, ≅0.00196.

Finding the fraction with the number of ways to have a flush as the numerator and the number of possible five-card hands as the denominator will allow us to determine the likelihood.

Combinations will be used to find each of these numbers (we don't care about the draw order; only about what shows up in our hand). Combinations' general formula is Cn,k=n!/(k)!(n-k)! with k=picks and n=population

Let's first determine the denominator by selecting 5 cards at random from a deck of 52 cards: C52,5=52!/(5)!(525)!

=52!/(5!)(47!)

Let's assess it!

52×51×50^10×49×48^2×47!/5×4×3×2×47!=52×51×10×49×2=2,598,960

Let's now determine the numerator.

In order to examine each hand with five cards of the same suit, we will compute all hands that feature a flush (including straight flushes, royal flushes, and flushes) (with a suit having 13 cards in total). We can say that we understand this by:

C13,5

Remember that there are 4 suites in which this might occur, but we only want 1, so multiply by C4,1. Putting it all together, we obtain:

C4,1×C13,5=4!/(1!)(4−1)!×13!/(5!)(13−5)!=4!13!/3!5!8!

Let's assess this.

4!×13×12×11×10×9^3×8!/3×2×5×4!×8!=13×12×11×3=5148

(Remember that we just calculated all hands, including straight flushes and royal flushes, that have a flush component to them!

The probability of getting a hand with a flush is:

5148/2598960≅.00198

We may exclude straight and royal flush possibilities from the 5148 flush hands by excluding those hands (which are hands with 5 consecutive value cards in the same suit, such as 3, 4, 5, 6, and 7 of hearts). Since there are four suits and 10 potential ways to get a straight (A-5, 2-6, 3-7,..., 10-A), we can subtract 4 from 5148 to get 5108 hands, which gives us the result 5108/2598960=0.00196.

The probability of having a 5-card hand that is a flush or royal flush is 0.00196

Answer:

Exterior angle to be used for parking is 72°

Step-by-step explanation:

I've attached an image of a paralelogram.

Now, we are told that from the outside it looks like a parallelogram with one of the interior angles as 108.

This means that the bigger angle internally would be 108°

Which from the attached image is angle B internally or angle D internally.

So, the interior angle observed will be either at point B or D on the parallelogram.

Now, the sum of angles on a straight line is 180°

Thus,

Internal angle D + External Angle D = 180

Or

Internal angle B + External Angle B = 180

Internal angle is 108°

Thus;

External angle for either B or D = 180 - 108 = 72°

So the exterior angle to be used for parking is 72°

The equation of the line through the point (3,5) that cuts off the least area from the first quadrant is 5x + 3y - 30 = 0     .

In the question ,

it is given that ,

the required line passes through the points (3,5) and and cuts off the least area from the first quadrant .

Suppose that the line passes through the (t , 0) and (3 , 5) . , where t > 0 .

So , the y intercept will be (0 , 5t/(t - 3))

So , the area of the  triangle in the first quadrant will be ,

= (1/2)×t × 5t/(t - 3)

= 5t²/2(t - 3) .

Differentiating the given area with respect to t ,

we get ,

d/dt 5t²/2(t - 3)  = 5t/(t-3) - 5t²/2(t-3)²

= 5t/2(t-3)²  × (2(t-3)-t)

= 5t/2(t-3)²  × (t-6)

So , the zero of the derivative will be at t = 6 .

So , the points will be (6,0) and (3,5) .

the equation of the line passing through the points (6,0) and (3,5) is

5x + 3y - 30 = 0 .

Therefore , the equation of the line is 5x + 3y - 30 = 0    .

Step-by-step explanation:

Given

f(x) = 4\(x^{5}\) + 5x³ + x² + 11

The degree of the polynomial is the value of the largest exponent

Th term with the largest exponent is \(x^{5}\) with exponent 5

Thus the degree of the polynomial is degree 5

The leading coefficient is the numeric coefficient of the leading term in standard form.

The leading term is 4\(x^{5}\) with leading coefficient of 4

The constant term is the term with no variable attached.

The constant term is therefore + 11

Approximating the sum of the series by the tenth partial sum, we have the following result:

∑ (n=1 to ∞) 1/n^5 ≈ s10 = 1/1^5 + 1/2^5 + 1/3^5 + ... + 1/10^5 ≈ 1/1 + 1/32 + 1/243 + ... + 1/100,000 ≈ 0.8413 (rounded to four decimal places).

In this approximation, we sum the reciprocals of the fifth powers of natural numbers from 1 to 10. The tenth partial sum, denoted as s10, represents the sum of the series up to the 10th term. By evaluating each term and adding them together, we obtain the approximate value of 0.8413. This approximation provides an estimation of the sum of the series while considering a finite number of terms, allowing for a simplified calculation of the overall sum.

The surface area of the box, excluding overlap, is 400 square inches.

The volume of the gift box is 300 cubic inches.

To calculate the amount of wrapping paper Malia will need, we need to find the surface area of the gift box.

The gift box has six faces: a top, a bottom, a front, a back, and two sides. The dimensions of the box are given as follows:

width = 15 inches, length = 10 inches, and height = 2 inches.

To find the surface area of the box, we need to calculate the area of each face and then sum them up.

The formula for the surface area of a rectangular prism is given by:

Surface Area = 2(length × width + width × height + height × length)

Substituting the given dimensions into the formula:

Surface Area = 2(10 × 15 + 15 × 2 + 2 × 10)

Surface Area = 2(150 + 30 + 20)

Surface Area = 2(200)

Surface Area = 400 square inches

Therefore, Malia will need 400 square inches of wrapping paper to cover the gift box without any overlap.

Next, let's calculate the volume of the gift box.

The volume of a rectangular prism is given by the formula:

Volume = length × width × height

Substituting the given dimensions into the formula:

Volume = 10 × 15 × 2

Volume = 300 cubic inches
