The large, central vacuole in a cell absorbs water and stores both nutrients and waste products.

The vacuole is a membrane-bound organelle found in the cells of many organisms, including plants, fungi, and some protists. It plays a vital role in maintaining cell homeostasis and performing various functions.

The central vacuole, which is typically found in plant cells, is the largest and most prominent vacuole within the cell. It occupies a significant portion of the cell's volume and is surrounded by a membrane known as the tonoplast.

One of the primary functions of the central vacuole is to regulate the osmotic pressure within the cell. It achieves this by absorbing water from the surrounding environment or releasing water when the cell needs to shrink or maintain turgor pressure.

Additionally, the central vacuole acts as a storage compartment for various substances. It can store water, ions, sugars, pigments, toxins, and other metabolites. It also serves as a repository for waste products that need to be sequestered within the cell.

Moreover, the central vacuole contributes to the rigidity and structural support of plant cells. By occupying a significant portion of the cell's interior, it helps maintain cell shape and prevents the cell from collapsing under external pressure.

In summary, the large, central vacuole in a cell is responsible for absorbing water, storing nutrients and waste products, regulating osmotic pressure, providing structural support, and participating in various cellular processes.

It can be seen that f(t) ≥ f(1) = 0 for t ≥ 1, which establishes the inequality.

In order to establish the inequality when t is greater than or equal to 1, it is necessary to examine the function.

f(t) = (t + 1)(t³ - 1)/[3t(t² + 1)] - log(t).

It will be demonstrated later in the text that f(t) is positive when t is equal to or greater than 1.

One can start by noting that the value of f at 1 is equal to 0.

Next, compute the derivative f'(t) and simplify to obtain:

f'(t) = (2t² - t - 1)/(t²(t² + 1)²)

For t ≥ 1, the denominator is always positive.

The numerator is a quadratic with roots 1 and -1/2.

Since t ≥ 1, the value in the top part of the fraction is positively positioned.

f'(t) > 0 for t ≥ 1.

Since f'(t) is positive for t ≥ 1, f(t) is non-decreasing.

Thus, f(t) ≥ f(1) = 0 for t ≥ 1, which establishes the inequality.

Step-by-step explanation:

To find the 80% confidence interval, we must first determine the critical value (z-score) corresponding to 80%. For this, we would use a z-table or a statistical calculator.

I am an AI, and will use a programming function to find it:

```python

import scipy.stats as st

confidence_level = 0.8

z_score = st.norm.ppf(1 - (1 - confidence_level) / 2)

rounded_z_score = round(z_score, 2)

```

This gives us a z-score of 1.28. Next, we will find the standard error, which is the standard deviation divided by the square root of the sample size:

Standard Error (SE) = (σ / sqrt(n)) = (12.8 / sqrt(53))

Now, we will find the margin of error (M.E.), which is the product of the z-score and the standard error:

Margin of Error (M.E.) = (z-score * SE) = (1.28 * (12.8 / sqrt(53)))

Finally, we will find the lower and upper bounds of the 80% confidence interval:

Lower Bound = (sample mean - M.E.) = (16.8 - M.E.)

Upper Bound = (sample mean + M.E.) = (16.8 + M.E.)

To one decimal place, the 80% confidence interval is:

(16.8 - M.E., 16.8 + M.E.)

80% C.I. = (16.8 - 1.28 * (12.8 / sqrt(53)), 16.8 + 1.28 * (12.8 / sqrt(53)))

Garage B is more cost-effective for any parking duration exceeding 2 hours.

When comparing Garage A and Garage B based on their pricing structure, it's important to consider both the flat fee and the hourly rate to determine which option is more cost-effective.

Garage A charges a flat fee of $5, regardless of the duration of parking, and an additional $2 for every hour parked. This pricing structure benefits those who need to park for shorter durations, as the flat fee is relatively low.

However, for longer parking durations, the hourly charge can accumulate significantly, making it less favorable for extended stays.

On the other hand, Garage B follows a different approach by charging a rate of $4.50 per hour with no flat fee. This pricing structure is more suitable for those who require shorter parking times, as they only pay for the exact duration of their stay. In such cases, Garage B would likely be more cost-effective compared to Garage A.

However, for longer stays, Garage A might offer better value. For example, if someone needs to park for 6 hours, Garage A would charge $17 ($5 flat fee + 6 hours * $2/hour) while Garage B would charge $27 ($4.50/hour * 6 hours). In this scenario, Garage A would be the more affordable option.

Ultimately, the choice between Garage A and Garage B depends on the individual's specific parking needs. If the stay is anticipated to be short, Garage B's hourly rate is preferable.

However, for longer durations, Garage A's combination of a flat fee and hourly rate may result in lower overall costs. It's essential to consider the anticipated length of stay to make an informed decision.

Answer:

To determine the maximum height reached by the golf ball before it returns to the ground, we can analyze the given quadratic function:

y = -16x^2 + 80x

This quadratic function represents the height of the golf ball at time 'x' seconds. The maximum height occurs at the vertex of the quadratic equation, which can be found using the formula: x = -b / (2a).

For this function, a = -16 and b = 80. Substituting these values into the formula, we have:

x = -80 / (2 * -16)

x = -80 / -32

x = 2.5

To find the maximum height, substitute this value of 'x' back into the original equation:

y = -16(2.5)^2 + 80(2.5)

y = -16(6.25) + 200

y = -100 + 200

y = 100

Therefore, the golf ball reaches a height of 100 feet before it begins to return to the ground.

Perpendicular lines have slope value that are negative reciprocals to each other.

Given the equation of a line as, y = 2x - 2, the slope is 2. Therefore, we have:

Substitute m = -1/2 and (a, b) = (7, 5) into y - b = m(x - a) to find the perpendicular line equation:

y - 5 = -1/2(x - 7)

Rewrite in slope-intercept form:

y - 5 = -1/2x + 7/2

y = -1/2x + 7/2 + 5

Given that,

BeeBright is a company that makes wax candles in the shape of a solid sphere.

Diameter of each candle = 15 cm

We have to find the volume of each candle.

Since the candles are in the shape of a solid sphere,

Volume of the candle = Volume of the sphere

                                    = 4/3 π r³, where r is the radius of the candle.

Radius of candle = Diameter / 2 = 7.5 cm

Volume of a candle = 4/3 π (7.5)³

A distance of x miles is represented by √10 inches on this map. The exact value of √10 is approximately 3.16 Option D.

To determine the number of inches on the map that represent a distance of x miles, we need to consider the given scale, which states that one inch on the map represents an actual distance of 10 miles.

If we set up a proportion using this information, we can solve for the unknown number of inches. The proportion would be:

1 inch (on the map) / 10 miles (actual distance) = x inches (on the map) / x miles (actual distance)

To simplify the proportion, we can cross-multiply:1 inch * x miles = 10 miles * x inches

This simplifies to:

x inches * x miles = 10 miles

Rearranging the equation, we get:

[tex]x^2 = 10[/tex]

To solve for x, we take the square root of both sides:

[tex]\sqrt{(x^2)} = \sqrt{10}[/tex]

Simplifying further, we have:

Therefore, a distance of x miles is represented by √10 inches on this map. The exact value of √10 is approximately 3.16. Hence, the closest answer choice that corresponds to this is  3.
