Answer:

f(x) = 2x^2 + 12x +10

Step by step solution:

x = 1 x = 5 y = 10

f(x) = a(x+1)(x+5)

f(0) = a(1)(5) = 10

5a = 10

Divide by 5

a = 2

f(x)= 2(x+1)(x+5)

f(x) = 2(x^2 +6x +5)

f(x) = 2x^2 + 12x +10

75% = 0.75

750 people / 0.75 = 1,000 people

There were 1,000 total people attending the game

Answer:

1,000 people

Step-by-step explanation:

At a basketball game, 75% of people attending were supporting the home team, while 25% were supporting the visiting team. If 750 people attending the game supported the home team, the total number of people attending the game was 1,000 people.

75% = 3/4 or 0.75

25% = 1/4 or 0.25

We need to find what 25% is.

75/3=25

75% = 0.75

750 people / 0.75 = 1,000 people

Therefore, there were 1,000 people at the game.

The actual implications of giving a bone to a subject would depend on the specific context, such as the subject's identity (human or animal), the purpose of giving the bone, and the cultural or medical considerations involved.

Assuming that a randomly selected subject is given a bone, it seems that we need to consider the context and determine the implications or consequences of this action. Without further information, it is difficult to provide a specific explanation or analysis. However, we can discuss some general possibilities and considerations related to giving a bone to a subject.

1. Medical Treatment: Giving a bone could be related to medical treatment or procedures. For example, in orthopedic medicine, bones may be used for grafting or reconstructive surgeries to repair damaged or fractured bones.

2. Nutritional Benefits: Bones, such as beef or chicken bones, can be used to make broths or stocks that are rich in nutrients like collagen, calcium, and other minerals. These bone-based products are often consumed for their potential health benefits.

3. Animal Care: Giving a bone to an animal, particularly dogs, is a common practice. Bones can serve as a form of entertainment or enrichment for pets, satisfying their chewing instincts and providing dental benefits.

4. Symbolic Meaning: In certain cultures or traditions, bones can hold symbolic meanings. They may be used in rituals, ceremonies, or artistic expressions to represent various concepts, such as strength, mortality, or spirituality.It's important to note that the above interpretations are speculative and based on general assumptions. The actual implications of giving a bone to a subject would depend on the specific context, such as the subject's identity (human or animal), the purpose of giving the bone, and the cultural or medical considerations involved.

Explanation:

Given that: ⁶√(25)³

= (25³)^1/6 {since, n√a = a^1/n}

= 25^(3*1/6) {since, (a^m)^n = a^(mn)}

In power 3 will cancel 6 in two times.

so,

= (25)^1/2 {since, 25 = 5*5 = 5²}

= (5²)^1/2 {since, (a^m)^n = a^(mn)

= 5^(2*1/2)

In power 2 wI'll cancel 2 in one time.

= 5^1 = 5

Therefore, ⁶√(25)³ = 5Ans.

The value of x would be 30 degrees.

The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.

Let's consider an angle CAD be t.

In a triangle ABD

x + 90 + t = 180

t = 180 -x - 90

t = 90 - x ( by angle sum property)

Now, we know that the sum of the corresponding angle on a transversal is 180

So,

Angle A + angle D = 180

2x + t + x + x = 180

substitute the t value

2x + 90 - x + 2x = 180

3x + 90 = 180

3x = 90

x = 30 degree

Hence, the value of x would be 30 degrees.

There are multiple strategies we can use to find the diameter of a circle. For this question, we must calculate the length of the radius first and multiply by 2 to find the diameter.

We're given the centre and a point on the circumference: \((-2,1),(6,7)\).

Find the distance between them using the distance equation:

\(d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)

Plug in the given points:

\(d=\sqrt{(-2-x_1)^2+(1-y_1)^2}\\d=\sqrt{(-2-6)^2+(1-7)^2}\\d=\sqrt{(-8)^2+(-6)^2}\\d=\sqrt{64+36}\\d=\sqrt{100}\\d=10\)

Therefore, the radius of the circle is 10 units.

Multiply the radius by 2 to find the length of the diameter:

10 × 2

= 20

Therefore, the length of the diameter is 20 units.

20 units

Yes, such a function exists. One example of such a function is the function \(f(x) = -x^3\).

Let's analyze the properties of this function:

\(f(x) > 0\): For any positive or negative value of x, when plugged into the function \(f(x) = -x^3\), the result will always be a negative number. Hence, \(f(x) > 0\).

f'(x) < 0: Taking the derivative of f(x) with respect to x, we get \(f'(x) = -3x^2\). The derivative is negative for all non-zero values of x, indicating that the function is decreasing for all x.

f''(x) > 0: Taking the second derivative of f(x) with respect to x, we get f''(x) = -6x. The second derivative is positive for all non-zero values of x, indicating that the function is concave up.

Therefore, the function \(f(x) = -x^3\) satisfies the given conditions: f(x) > 0, f'(x) < 0, and f''(x) > 0 for all x.

The number of cases per batch that should be produced to minimize cost can be found by using the Economic Order Quantity.

The Economic Order Quantity (EOQ) is a calculation performed by a business that represents the ideal order size that allows the business to meet demand without overspending. The inventory manager calculates her EOQ to minimize storage costs and excess inventory.  

Thus:

Number of cases per batch = √((2 * Setup costs * annual demand)/ holding costs for the year)

The measure of arc angle HE is determined as 190 ⁰.

The measure of angle subtended by the arc HE is calculated by applying the following formula.

Based on the angle of intersecting chord theorem, we will have the following equation.

m∠EFG = ¹/₂( HE - EG )

66 =  ¹/₂( HE - 58 )

2x 66 = HE - 58

132 = HE- 58

HE = 132 + 58

The standard for deciding whether an observed result is due to chance is called statistical significance.

statistical significance refers to the likelihood that the observed results are not due to chance alone but are instead the result of a real effect or relationship. This is determined through statistical tests, such as the p-value, which calculates the probability of obtaining the observed results if the null hypothesis (i.e. no effect or relationship) were true. If the probability is low enough (typically below 0.05), then the results are considered statistically significant.

Answer:

\(a_n=a_{n-1}+2^{n-1}\ \ n>1\)

Step-by-step explanation:

Recursive Sequence

We are given the following sequence:

-1, 1, 5, 13...

It's required to find the recursive term for the sequence.

A recursive formula calculates each term as a function of one or more previous terms.

To find the recursive formula, we must find a pattern and transform it into a math expression.

Let's write the sequence, and below it, the difference of consecutive terms:

-1,   1,   5,   13...

+2,  +4,  +8

Note the difference between consecutive terms is always a power of 2, starting from 2^1, 2^2, 2^3.

The exponent is one less than the number of the term, thus:

\(a_n-a_{n-1}=2^{n-1}\)

Thus:

\(\mathbf{a_n=a_{n-1}+2^{n-1}\ \ n>1}\)

n=1

\(a_1=-1\) (given).

There are several different sampling methods that could be employed for this study, including:

Simple random sampling: This method involves randomly selecting a certain number of students from each campus and measuring the distance between their hometowns and their campuses.

Stratified random sampling: This method involves dividing the student population at each campus into different strata (e.g. by major or year in school) and then randomly selecting a certain number of students from each stratum.

Cluster sampling: This method involves randomly selecting a certain number of campuses and then measuring the distance between the hometowns of all students at those campuses and their respective campuses.

Multi-stage sampling: This method involves using a combination of the above methods, such as first using cluster sampling to select a certain number of campuses and then using stratified random sampling to select a certain number of students from each campus.

This study would be an enumerative study because it seeks to measure the characteristics of a population, in this case, the average distance between the hometowns of students and their campuses, by counting and measuring them.

It is not an analytic study because it doesn't involve testing a hypothesis or making causal inferences.
