The required simplified expression is: x² - 9/ 9x⁴ + 9x² for all x ≠ 0 or 3.

The given expression below is:

x² - 9 / (3x²)(3x²) + 9x²

To simplify the given expression, we must first distribute the terms on the numerator and denominator.

The numerator becomes x² - 9 and the denominator becomes (3x²)(3x²) + 9x².

Next, we must simplify the denominator by combining like terms. The denominator becomes 9x⁴ + 9x².

Finally, we can simplify the entire expression by dividing the numerator by the denominator.

This gives us the simplified expression: x² - 9/ 9x⁴ + 9x².

Note that this expression is not defined when x = 0 or x = 3, as it would result in a division by zero.

Thus, the final simplified expression is x² - 9/ 9x⁴ + 9x² for all x ≠ 0 or 3.

The fraction of the distances of the points A(2·a + 3, 3·a + 4), and B(4 - a, 5 - a) from the x- and y-axis and the value of a > 5, indicates that the value of a is 16.[tex]\overline{4}[/tex]

A fraction is a representation of the amount a part of an item compared to the whole of the item.

The distance from the x-axis to the point A(2·a + 3, 3·a + 4) = 3·a + 4

The distance from the y-axis to the point B(4 - a, 5 - a) = 4 - a

Therefore; 1/5 of the distance from the x-axis to the point A(2·a + 3, 3·a + 4) is (1/5) × (3·a + 4)

6/7 of the distance from the y-axis to the point B(4 - a, 5 - a) is (6/7) × (4 - a)

The details in the question indicates; (1/5) × (3·a + 4) = (6/7) × (4 - a)

However, if a > 5, then 4 - a < 0, while (3·a + 4) > 0, from which we get;

If a > 5, then, (1/5) × (3·a + 4) = (6/7) × (a - 4)

The expected value for Alison's investment is $650

A projected average value for an investment at some point in the future is known as the expected value (EV).

A anticipated value for an investment is called expected value (EV). It is determined by averaging all conceivable outcomes, multiplied by the likelihood that they will occur. The long-term average of random variables is known as EV. Additionally, it is the probability-weighted average of every potential value.

Given:

There is a 35% chance that she will make $4000.

25% chance that she will lose $3000.

and a 40% chance that she will break even (make $0).

The expected value can be calculated as:

= ∑ (Probability of event happening x Payoff if event happens)

So, The expected value  is

= (35% x 4000) + (25% x -(3,000)) + (40% x 0)

(a) A sample size of 784.44 is required to estimate the population proportion to within an error of 0.03 with 95% confidence.

(b) A sample size of 393.22 would be required if no information from a pilot study is available.

What is a sample size?

Sample size refers to the number of observations or measurements that are taken from a larger population as part of a statistical study. In statistical analysis, a sample is a subset of the population being studied, and the sample size is the number of observations or units of analysis included in the sample.

To answer this question, we need to use the formula for the sample size of a proportion:

[tex]n = \frac{Z^2 * p * (1 - p))}{e^2}[/tex]

Where n is the sample size, Z is the z-score corresponding to the desired confidence level (in this case, Z = 1.96 for a 95% confidence level), p is the estimated population proportion (in this case, p = 0.75 based on the information provided in the question), and e is the desired margin of error (in this case, e = 0.03).

Plugging these values into the formula, we get:

[tex]n = \frac{(1.96^2 * 0.75 * 0.25)}{0.03^2} \\\\n= 784.44[/tex]

If no information from a pilot study is available, we would need to use a default value for p (such as p = 0.5) in the formula. In this case, we would get:

[tex]n = \frac{(1.96^2 * 0.5 * 0.5)}{0.03^2}\\\\n= 393.22[/tex]

Hence,

(a) A sample size of 784.44 is required to estimate the population proportion to within an error of 0.03 with 95% confidence.

(b) A sample size of 393.22 would be required if no information from a pilot study is available.

Answer:

To solve this problem, we first need to find out how much time it will take for the airplane that is descending to reach the same altitude as the airplane that is ascending. To do this, we can use the formula d = r * t, where d is the distance, r is the rate, and t is the time.

In this case, the distance is the difference between the starting altitudes of the two airplanes, which is 42,000 feet for the descending airplane and 0 feet for the ascending airplane. The rate is the rate at which the descending airplane is descending, which is 3,500 feet per minute. Plugging these values into the formula, we get:

d = r * t

d = (3,500 feet/minute) * t

d = 42,000 feet

Solving for t, we get:

t = d / r

t = (42,000 feet) / (3,500 feet/minute)

t = 12 minutes

So it will take 12 minutes for the descending airplane to reach the same altitude as the ascending airplane.

To find the altitude at which the two airplanes will be at the same altitude, we can use the formula d = r * t, where d is the distance, r is the rate, and t is the time. In this case, the distance is the altitude at which the two airplanes will be at the same altitude, the rate is the rate at which the ascending airplane is ascending, which is 2,500 feet per minute, and the time is the time it will take for the descending airplane to reach the same altitude as the ascending airplane, which we calculated to be 12 minutes.

Plugging these values into the formula, we get:

d = r * t

d = (2,500 feet/minute) * (12 minutes)

d = 30,000 feet

Therefore, the altitude at which the two airplanes will be at the same altitude is 30,000 feet.

There are several other ways we could have solved this problem. For example, we could have used the formula d = r * t to find the altitude of the ascending airplane at the same time that the descending airplane reaches the same altitude, and then subtracted the starting altitude of the ascending airplane (0 feet) from this value to find the altitude at which the two airplanes will be at the same altitude.

Another way to solve this problem is to use the formula d = (v1 + v2) * t / 2, where d is the distance, v1 and v2 are the rates at which the two airplanes are moving, and t is the time. In this case, we can set d equal to the difference between the starting altitudes of the two airplanes, v1 equal to the rate at which the descending airplane is descending, v2 equal to the rate at which the ascending airplane is ascending, and t equal to the time it will take for the descending airplane to reach the same altitude as the ascending airplane.

Plugging these values into the formula, we get:

d = (v1 + v2) * t / 2

d = (3,500 feet/minute + 2,500 feet/minute) * (12 minutes) / 2

d = (6,000 feet/minute) * (12 minutes) / 2

d = (72,000 feet) / 2

d = 36,000 feet

Therefore, the altitude at which the two airplanes will be at the same altitude is 36,000 feet.

We can also solve this problem using a table to track the altitude of the two airplanes over time. We can start by making a table with

The amount that Alan can be able to borrow for credit balance is $8,500.

What is credit balance?

The capacity to access products or services or borrow money with the idea that you'll pay for them later is known as credit. An amount that the card issuer owes you can be seen as a credit balance on your billing statement. With each payment you make, credits are added to your account. When you return something you purchased with a credit card, a credit might be added.

Given, total limit =  $10,000

Borrowed amount = $2,000

paid back = $500

So, remaining amount that he can borrow = $10,000 - $2,000 + $500

A limit is a value toward which an expression converges as one or more variables approach certain values, a limit tells us the value of a function when its input closes to a certain value. Limits are used to define continuity, derivatives, and integrals. The limit of a product is equal to the product of the limits. The limit of a quotient is equal to the quotient of the limits. The limit of a constant function is equal to the constant.

Given that a function, f(x) = ∛x

The formula for applying the limit is :-

The first derivative is given by,

f'(x) = limx->c (f(x) - f(c))/(x-c)
