Step-by-step explanation:
Using the Altitude- on- hypotenuse theorem
(leg of big Δ )² = (part of hypotenuse below it ) × ( whole hypotenuse), that is
x² = (30 - 6) × 30 = 24 × 30 = 720 ( take square root of both sides )
x = \(\sqrt{720}\) = \(\sqrt{144(5)}\) = \(\sqrt{144}\) × \(\sqrt{5}\) = 12\(\sqrt{5}\) → d

How do you determine if something is a factor of a function?.
Answers
if the function is divided and we get the remainder of zero then it is said to be a factor of a function
According to the Remainder Theorem, by a factor x − an of that polynomial, then you will get a zero remainder. The point of the Factor Theorem is the turnaround of the Remainder Theorem: On the off chance that you synthetic-divide a polynomial by x = a and get a zero remainder, at that point not as it were is x = a, a zero of the polynomial(for the remainder theorem ) but x − a is additionally a factor of the polynomial according to of the Factor Theorem.

2. During typhoon Ambo, PAGASA tracks the amount of accumulating rainfall. For
<en place.
the first three hours of typhoon, the rain fell at a constant rate of 25mm per hour.
The typhoon slows down for an hour and started again at a constant rate of 20 mm
per hour for the next two hours. Write a piecewise function that models the amount
of rainfall as function of time.
Answers
Answer:
The piecewise equation is given as :\(A(t)=\begin{cases} 25x& \text{ if } 0 \leq x \leq 3 \\ 75& \text{ if } 3<x<4 \\ 75+20(x-4) & \text{ if } 4 \leq x \leq 6\end{cases}\)
Step-by-step explanation:
Let x be the time in hour and A(x) be the amount of accumulating rainfall at time x.
We are given that in the first three hours the rain fell at a constant rate of 25mm per hour
Amount of rainfall in 1 hour = 25
Amount of rainfall in t hours = 25x
\(A(x) = 25x ; 0 \leq x \leq 3\)
The rain then slows down and remains constant
So, Amount of rain for that hour = \(25 \times 3 = 75 mm\)
75 mm ; 3
Now we are given that started again at a constant rate of 20 mm per hour for the next two hours.
Amount of rain after 4 hours = \(75+20(x-4) ; 4 \leq x\leq 6\)
The rain increases at a rate of 20t from 4 ≤ x ≤ 6.
Hence the piecewise equation is given as :\(A(t)=\begin{cases} 25x& \text{ if } 0 \leq x \leq 3 \\ 75& \text{ if } 3<x<4 \\ 75+20(x-4) & \text{ if } 4 \leq x \leq 6\end{cases}\)

The angle of elevation necessary for a hit ball to just clear the center field fence is not the only factor that goes into determining whether the ball clears the fence. What might be some other determining factors, and how do they play a role in the ball’s final destination? Provide at least two other determining factors.
Answers
Other factors like temperature, air density, and humidity can affect the ball's flight. For instance, denser air, often associated with colder temperatures, can impede the ball's movement and reduce its travel distance.
In addition to the angle of elevation, several other determining factors come into play when determining whether a hit ball will clear the center field fence. Two significant factors to consider are the initial velocity of the ball and the atmospheric conditions.
The initial velocity of the ball strongly influences its trajectory and distance. A higher initial velocity will result in a longer travel distance, increasing the chances of clearing the fence. However, if the ball is not hit with enough velocity, it may not have the necessary power to surpass the fence height.
Atmospheric conditions, including wind speed and direction, can greatly impact the ball's flight path. A strong tailwind can provide additional lift and carry to the ball, aiding its trajectory and helping it clear the fence. Conversely, a headwind can have the opposite effect, causing the ball to lose speed and distance, potentially falling short of the fence.
Furthermore, other factors like temperature, air density, and humidity can affect the ball's flight. For instance, denser air, often associated with colder temperatures, can impede the ball's movement and reduce its travel distance.
Considering these factors along with the angle of elevation provides a more comprehensive understanding of whether a hit ball will clear the center field fence. Each factor interacts and contributes to the ball's final destination, making baseball a game where multiple variables must be accounted for to achieve success.

Are the graphs of y = -2x + 4 and y = (1/4)x -2 parallel, perpendicular, or neither? *
Answers
Answer: Neither
Step-by-step explanation:
For this to be paralell it would need to have the same slope. (They don't have the same.) For this to perpandicular it would have to reciporcal ( Ex: -2 reciporcal would -1/2 or 1/4 reciprocal would have to be 4)
Answer:
neither
Step-by-step explanation:
For two lines to be parallel, their slopes must be equal.
For two lines to be perpendicular, their slopes must have a product of -1. (The only exception is a vertical line and a horizontal line which are perpendicular, but the product of their slopes is not -1.)
When the equation of a line is written in the slope-intercept form,
y = mx + b,
m is the slope.
y = -2x + 4 has a slope of -2.
y = (1/4)x -2 has a slope of 1/4.
Clearly, -2 and 1/4 are not equal, so the lines are not parallel.
Now we find the product of the slopes.
(-2) * (1/4) = -2/4 = -1/2
The product of the slopes does not equal -1, so the lines are not perpendicular.
Answer: neither

Answers
Ratios and proportions are the mathematical idea that proves to be most useful when dealing with probabilities. . Calculating probabilities and making judgments based on them require this understanding.
Working with probability requires the use of ratios and proportions. We can compare two different items using ratios and proportions to determine how they relate to one another in terms of size or value. For instance, if we are aware of the proportions of automobile owners and non-owners within a given age group, we can use this information to determine the likelihood that a randomly chosen member of that age group will be a car owner. Calculating the likelihood of separate events can also be done using ratios and proportions. For instance, if we know that the likelihood of one event happening is x and the likelihood of another.

How many solutions are there to the inequality x1 + x2 + x3 ≤ 11, where x1, x2, and x3 are nonnegative integers? [Hint: Introduce an auxiliary variable x4 such that x1 + x2 + x3 + x4 = 11.]
Answers
The number of nonnegative integer solutions to the inequality x1 + x2 + x3 ≤ 11 is C(14,3) = 364.
We can solve this inequality by introducing an auxiliary variable x4, such that x1 + x2 + x3 + x4 = 11. Here, x1, x2, x3, and x4 are all nonnegative integers.
We can interpret this equation as follows: imagine we have 11 identical objects and we want to distribute them among four boxes (x1, x2, x3, and x4). Each box can contain any number of objects, including zero. The number of solutions to this equation will give us the number of nonnegative integer solutions to the original inequality.
We can use a technique known as stars and bars to count the number of solutions to this equation. Imagine we represent the 11 objects as stars: ***********.
We can then place three bars to divide the stars into four groups, each group representing one of the variables x1, x2, x3, and x4. For example, if we place the first bar after the first star, the second bar after the third star, and the third bar after the fifth star, we get the following arrangement:
| ** | * | ****
This arrangement corresponds to the solution x1=1, x2=2, x3=1, and x4=7. Notice that the number of stars to the left of the first bar gives the value of x1, the number of stars between the first and second bars gives the value of x2, and so on.
We can place the bars in any order, so we need to count the number of ways to arrange three bars among 14 positions (11 stars and 3 bars). This is equivalent to choosing 3 positions out of 14 to place the bars, which can be done in C(14,3) ways.
Therefore, the number of nonnegative integer solutions to the inequality x1 + x2 + x3 ≤ 11 is C(14,3) = 364.

Answers
None of the listed methods are used for enumerating sample points in a multiple-step experiment. So, option D is the correct answer.
Graphical methods are important mathematical tools that are very helpful when it comes to managing a vast amount of data. These also help when we need to visually represent data. These methods help quite a lot since they make it easier to keep track of data and understand it as well.
A bar chart and a histogram are similar tools that are used to represent data by plotting them as rectangular bars. These can be either vertical or horizontal. A pie chart is also a tool that uses a shape for data visualization. In its case, it represents data in the shape of a circle and all categories/data sets have their slices. So, this means that these three are not methods that can be used for enumerating sample points in a multiple-step experiment. Hence, option D is the correct option.

How to calculate the 97% confidence interval?Hi, I'd be happy to help you calculate the 97% confidence interval for the given data. To find the 97% confidence interval for a sample of 204 soda cans with a mean amount of 12.05 ounces and a standard deviation of 0.08 ounces, follow these steps:
1. Identify the sample size (n), mean (µ), and standard deviation (σ): n = 204, µ = 12.05, σ = 0.08
2. Determine the confidence level, which is 97%. To find the corresponding z-score, you can use a z-table or calculator. The z-score for 97% confidence is approximately 2.17.
3. Calculate the standard error (SE) using the formula: SE = σ / √n. In this case, SE = 0.08 / √204 ≈ 0.0056.
4. Multiply the z-score by the standard error to find the margin of error (ME): ME = 2.17 × 0.0056 ≈ 0.0122.
5. Find the lower and upper bounds of the confidence interval by subtracting and adding the margin of error to the mean, respectively: Lower bound = 12.05 - 0.0122 ≈ 12.0378, Upper bound = 12.05 + 0.0122 ≈ 12.0622.
So, the 97% confidence interval for this sample is approximately (12.0378, 12.0622), which is closest to the option (12.038, 12.062).
