Jake tosses a coin up in the air and lets it fall to the ground. The equation that models the height (in feet) and time (in seconds) of the parabola is h(t)= -16t^2+ 24t+6. What is the height of the coin when Jake tosses it?

Answer:

120°

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

A hexagon has 6 sides, thus

sum = 180° × 4 = 720°

To find the measure of each interior angle divide by 6, that is

interior angle = 720° ÷ 6 = 120°

Answer: 120°

Step-by-step explanation: Let's start by finding the sum of the measures of the interior angles. The sum of the measures of the interior angles of a polygon can be found using the formula 180 (n - 2) where n represents the number of sides in the polygon.

Since a regular hexagon has 6 sides, we can plug a 6 in for n in our formula and we have 180 (6 - 2) where 6 represents the number of sides. We can simplify this by subtracting 2 from 6 inside the parentheses to get 180 (4) which is 720.

So the sum of the measures of the interior angles of a regular hexagon is 720°.

However, we want to know the measure of each interior angle. Since the angles of a regular hexagon are all congruent, we simply divide the sum of the measures of the angles which is 720 by the number of angles or sides which is 6 to get 120.

So the measure of each interior angle of a regular hexagon is 120°.

So the formula for finding the measure of each interior angle of a regular polygon is simply the sum of the interior angles 180 (n - 2) divided by the number of sides which is n.

The total number of boxes will be 60 that the girls have sold in one hour.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

We have to determine the total number of boxes will the girls have sold in one hour

Let Kate sold x boxes in 60 minutes

As per the given situation, we can write the ratio would be as:

27 boxes : 45 minutes = x boxes :  60 minutes

⇒ 27/45 = x/60

Apply the cross-multiplication operation,

⇒ x = (60×27)/45

⇒ x = 36

Let Miley sold y boxes in 60 minutes

⇒ 12/30= y/60

Apply the cross-multiplication operation,

⇒ y = (12×60)/30

⇒ y = 24

So, the total number of boxes = x + y = 36 + 24 = 60

Thus, the total number of boxes will be 60 that the girls have sold in one hour.

Final answer:

Kate sells 36 boxes and Miley sells 24 boxes in one hour. So, they will have sold a total of 60 boxes in one hour.

Explanation:

To find the total number of boxes sold by both Kate and Miley in one hour, we need to calculate the rate at which each of them sells boxes. Kate sells 27 boxes in 45 minutes, which can be converted to 0.6 boxes per minute (27 boxes / 45 minutes = 0.6 boxes per minute). Miley sells 12 boxes in 30 minutes, which can be converted to 0.4 boxes per minute (12 boxes / 30 minutes = 0.4 boxes per minute).

To find the total number of boxes sold in one hour, we add the number of boxes each of them sells in one minute and multiply it by 60 (the number of minutes in an hour). Kate sells 0.6 boxes per minute, so in one hour she would sell 0.6 boxes/minute * 60 minutes = 36 boxes. Miley sells 0.4 boxes per minute, so in one hour she would sell 0.4 boxes/minute * 60 minutes = 24 boxes. Therefore, the total number of boxes sold by both Kate and Miley in one hour would be 36 + 24 = 60 boxes.

C. 3.16 is the right answer

Step-by-step explanation:

The distance formula used in coordinate geometry is derived from the Pythagorean theorem.

The distance formula is give by:

[tex]d=\sqrt{(x_2-x_2)^2+(y_2-y_1)^2}[/tex]

Here (x1,y1) are the coordinates of first point and (y1,y2) are the coordinates of second point

Here,

(x1,y1) = (5,-3)

(x2,y2) = (6,0)

Putting the values in the formula

[tex]AB = \sqrt{(6-5)^2+(0-(-3))^2}\\=\sqrt{(1)^2+(0+3)^2}\\=\sqrt{(1)^2+(3)^2}\\=\sqrt{1+9}\\=\sqrt{10}\\=3.16\ units[/tex]

The distance between two points is 3.16 units.

Answer:

width =4.5ft

length=6ft

Step-by-step explanation:

w = x

L = 2x-3

area = L*w

27 = x(2x-3)

[tex]27=2x^{2} -3x[/tex]

[tex]2x^{2} -3x-27=0[/tex]

[tex]2x^{2} +6x-9x-27=0[/tex]

2x(x+3)-9(x+3)=0

(2x-9)(x+3)=0

2x-9=0

2x=9

x=9/2

x=4.5

L=2x-3=2*4.5-3 =9-3=6

The dimensions of the rectangle are; width = 4.5ft and length = 6ft.

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

The length of the rectangle is 3ft less than twice the width.

Let width = x

Length = 2x - 3

The area of the rectangle = length × Width

27 = x(2x-3)

2x² - 3x = 27

2x² - 3x - 27 = 0

2x(x + 3) - 9(x + 3) = 0

(2x-9)(x+3)=0

The solutions are;

2x-9=0

2x=9

x=9/2

x = 4.5

(x+3) = 0

x = -3

The width cannot be negative.

So,

Length = 2x-3 = 2*4.5-3 = 9 - 3

Length = 6

Hence, The dimensions of the rectangle are; width = 4.5ft and length = 6ft.

Answer:57

Step-by-step explanation:

Conversion factor is

1 US bushel = 4 US pecks

76 rows x 3 pecks= 228 pecks

228 pecks / 4 = 57

To plant 76 rows of seed potatoes, with 3 pecks per row, we would need a total of 57 bushels, as there are 0.75 bushels per row and this is multiplied by the number of rows.

To answer this question, we first need to understand the relationship between bushels and pecks. There are 4 pecks in one bushel. If 3 pecks are planted per row, then each row requires 0.75 bushels (because 3/4 = 0.75). So, to find the number of bushels needed for 76 rows, we multiply 76 by 0.75.

The final calculation is: 0.75 bushels/row * 76 rows = 57 bushels.

The coefficient of skewness is 0.26, indicating slight positive skewness and the kurtosis is approximately -0.84, indicating a platykurtic distribution.

We have,

To calculate the coefficient of skewness and kurtosis, we first need to organize the data into a frequency distribution table.

Age | Frequency

10 | 3

12 | 2

13 | 4

14 | 5

15 | 5

16 | 5

17 | 4

18 | 6

19 | 4

20 | 3

32 | 3

34 | 3

35 | 3

37 | 1

38 | 1

40 | 1

43 | 1

44 | 2

To calculate the coefficient of skewness, we use the formula:

Coefficient of Skewness = (mean - mode) / standard deviation

Mean = (10 * 3 + 12 * 2 + 13 * 4 + ... + 44 * 2) / 100 ≈ 20.49

Mode = 18 (the most frequent value in the dataset)

Standard Deviation

= √[((10 - mean)² * 3 + (12 - mean)² * 2 + ... + (44 - mean)² * 2) / 100]

≈ 9.63

Coefficient of Skewness = (20.49 - 18) / 9.63 ≈ 0.26

To calculate the kurtosis, we use the formula:

Kurtosis = ∑[((x - mean) / standard deviation)⁴ * frequency] / (n * standard deviation⁴) - 3

Kurtosis = [((10 - mean) / standard deviation)⁴ * 3 + ((12 - mean) / standard deviation)⁴ * 2 + ... + ((44 - mean) / standard deviation)⁴ * 2] / (100 * standard deviation⁴) - 3 ≈ -0.84

Interpretation:

Coefficient of Skewness:

The coefficient of skewness is positive (0.26), indicating that the data is slightly skewed to the right (positively skewed). This means that there is a longer tail on the right side of the distribution.

Kurtosis:

The kurtosis value is approximately -0.84. Since it is less than 3, the distribution is considered platykurtic. This means that the distribution has lighter tails and is flatter compared to a normal distribution.

Thus,

The coefficient of skewness is 0.26, indicating slight positive skewness and the kurtosis is approximately -0.84, indicating a platykurtic distribution.

Answer: x = 12

Step-by-step explanation:

First you must simplify:

x + (x + 4) = 28

Reorder the terms:

x + (4 + x) = 28

Remove parenthesis around (4 + x):

x + 4 + x = 28

Reorder the terms:

4 + x + x = 28

Combine like terms: x + x = 2x

4 + 2x = 28

Solving

4 + 2x = 28

Now we must solve for the variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4' to each side of the equation.

4 + -4 + 2x = 28 + -4

Combine like terms: 4 + -4 = 0

0 + 2x = 28 + -4

2x = 28 + -4

Combine like terms: 28 + -4 = 24

2x = 24

Divide each side by '2'.

x = 12

The value of the discriminant is 36, which means that the quadratic equation -2x = -8x + 8 has two distinct real solutions.

Explanation:

The given equation -2x = -8x + 8 can be rearranged into a quadratic equation: -8x + 8 + 2x = 0. Combining like terms gives: -6x + 8 = 0. To find the discriminant of this quadratic equation, we look at the coefficient of x^2, which is 0. Since the discriminant D = b^2 - 4ac, where a = coefficient of x^2, b = coefficient of x, and c = constant term, in this case, a = 0, b = -6, and c = 8. Plugging these values into the formula, we have: D = (-6)^2 - 4(0)(8) = 36 - 0 = 36.

The value of the discriminant is 36. The discriminant tells us about the number of real number solutions the equation has. If the discriminant is positive (D > 0), then the equation has two distinct real solutions. If the discriminant is zero (D = 0), then the equation has one real solution. If the discriminant is negative (D < 0), then the equation has no real solutions.

In this case, since the discriminant is positive (D = 36), the quadratic equation has two distinct real solutions.

The product of 576 and 684 is a rational number since it results in an integer, which is a subset of rational numbers.

The product of 576 and 684 is asked to be classified as rational or irrational. The multiplication of two integers will always produce another integer, as is the case with 576 multiplied by 684. Since all integers are rational numbers (they can be expressed as the ratio of two integers), the product, in this case, is also a rational number.

Therefore, the product of 576 and 684 is rational because it can be expressed as a ratio of the two integers (the product itself over 1), fitting the definition of a rational number which includes integers, fractions, finite decimals, and repeating decimals.

Final answer:

The product of 576 and 684 is a rational number because the multiplication of two integers always results in another integer.

Explanation:

The question asks whether the product of 576 and 684 is rational or irrational. A rational number is a number that can be expressed as a ratio of two integers. Since both 576 and 684 are integers, their product will also be an integer, as the multiplication of two integers always results in another integer. Therefore, this product is definitely a rational number. An irrational number, by contrast, cannot be expressed as such a ratio, and is typically found with non-repeating, non-terminating decimal expansions or with numbers like the square root of a non-square number. However, as there is no square root or any other irrational operation involved in multiplying 576 and 684, the result is rational.

Answer:

At least 55 tickets must be sold to cover the remaining cost of the party.

Step-by-step explanation:

Total money needed for the party  = $350

The money already with the committee  = $75

Now, the money yet to be collected = Total Party Budget - Money present

                                                              = $350  = $75  = $275

Now, the cost of 1 ticket  = $5

Let us assume the number of tickets sold to cover the cost of party = m

⇒ The cost of m tickets   = 5 m

The renaming cost = Total cost of m tickets

or, 5 m =  $275

⇒ m = 275/5  = 55

or, m = 55

Hence, at least 55 tickets must be sold to cover the remaining cost of the
