The inverse of f,  f^-1 = 8x / (x + 3)

To find the inverse function, let's consider the following steps:

Step 1: Replace f(x) with y. y = x/8x - 3

Step 2: Swap the x and y variables. x = y/8y - 3

Step 3: Solve for y. x(8y - 3) = y x 8y - 3x = y y = f⁻¹(x) = 8x / x + 3

Therefore, f⁻¹(x) = 8x / (x + 3)

The domain of f⁻¹ is all real numbers except -3, as it is not defined for x = -3.

Hence the domain is (-∞, -3) U (-3, ∞).

The range of f⁻¹ is also all real numbers except 0, as it is not defined for x = 0. Hence the range is (-∞, 0) U (0, ∞).

Thus, the domain and range of f⁻¹ are (-∞, -3) U (-3, ∞) and (-∞, 0) U (0, ∞) respectively, in interval notation.

according to question the simplified expression is (w + 4) / (w - 5).

To simplify the expression (w^2 + 2w - 24) / (w^2 + w - 30) + 8 / (w - 5), we need to first factor the two quadratic expressions in the numerator and denominator of the first term:

w^2 + w - 30 = (w - 5)(w + 6)

w^2 + 2w - 24 = (w + 6)(w - 4)

So, the first term simplifies to:

(w + 6)(w - 4) / (w - 5)(w + 6) = (w - 4) / (w - 5)

Now, we can rewrite the entire expression as:

(w - 4) / (w - 5) + 8 / (w - 5)

To combine the two fractions, we need to find a common denominator, which is (w - 5). Then, we can add the numerators:

[(w - 4) + 8] / (w - 5) = (w + 4) / (w - 5)

Answer:

283.5 cm squared

Step-by-step explanation:

The surface area of a solid is basically just the sum of the areas of all the exterior sides. In this figure, we have 3 congruent triangles at the top, 3 congruent rectangles on the sides, and 1 triangle at the base. We need to find all these areas.

3 congruent triangles:

The area of a triangle is denoted by: A = (1/2) * b * h, where b is the base and h is the height.

Here, the base of one triangle is 10 and the height is 4. So:

A = (1/2) * b * h

A = (1/2) * 10 * 4 = 20

Since there are 3 such triangles, multiply 20 by 3:

20 * 3 = 60 cm squared

3 congruent rectangles:

The area of a rectangle is denoted by: A = lw, where l is the length and w is the width.

Here, the length is 6 and the width is 10, so:

A = lw

A = 6 * 10 = 60

There are 3 such rectangles, so multiply 60 by 3:

60 * 3 = 180 cm squared

1 base triangle:

Again we use the formula A = (1/2) * b * h for this area.

Here, the base is 10 and the height is 8.7, so:

A = (1/2) * b * h

A = (1/2) * 10 * 8.7 = 43.5 cm squared

Add all these together:

60 + 180 + 43.5 = 283.5 cm squared

The answer is thus 283.5 cm squared.

Answer:

283.5 cm²

Step-by-step explanation:

3 rectangles + 3 triangles on top + triangular base

3(10×6) + 3(½×10×4) + (½×10×8.7)

180 + 60 × 43.5

283.5 cm²

Discounted fees serve to attract more customers, increase rental volume, and foster customer loyalty.

Discounted fees and rental fees in a bike shop are related in the sense that discounted fees usually represent a reduced or discounted rate applied to the standard rental fee. The discounted fees aim to incentivize customers and attract more business by offering lower prices for renting bikes.

Typically, bike shops have standard rental fees for different types of bikes and durations. These fees are set based on factors such as the type of bike, its condition, the rental duration (hourly, daily, weekly), and the market demand. However, bike shops may choose to offer discounts to certain customers or during specific periods to encourage more rentals.

Discounted fees can be applied in various ways:

1. Percentage discounts: The rental fee may be reduced by a certain percentage, such as 10% off the standard rental fee. For example, if the standard rental fee for a bike is $20 per day, a 10% discount would reduce the fee to $18.

2. Fixed amount discounts: A fixed dollar amount may be deducted from the standard rental fee. For instance, a bike shop may offer a $5 discount on all rentals, regardless of the rental duration or bike type.

3. Promotional discounts: Bike shops may introduce promotional offers or special deals that provide discounted fees for a limited time or specific circumstances. For example, they might offer discounted fees during off-peak seasons or for group rentals.

Discounted fees serve to attract more customers, increase rental volume, and foster customer loyalty. By offering lower prices, bike shops can incentivize potential customers to choose their services over competitors or encourage repeat business from existing customers.

discounted fees may reduce the rental revenue per transaction, the goal is to generate higher overall revenue by attracting a larger customer base and increasing rental frequency. The specific relationship between discounted fees and rental fees can vary based on the pricing strategy adopted by the bike shop and the market dynamics in which it operates.

An ellipse is a plane curve that surrounds two focus points and has a constant sum of the two distances to the focal points at all places on the curve. In the graph, the A represents the minor axis of the ellipse.

Suppose that the major axis is of the length 2a units, and that minor axis is of 2b units, and let the ellipse is centered on (h,k) with major ellipse parallel to x-axis, then the equation of that ellipse would be:

\(\dfrac{(x-h)^2}{a^2} + \dfrac{(y-k)^2}{b^2} =1\)

Coordinates of its foci would be: (h±c, k) where c² = a² - b²

If its major axis is parallel to y-axis, then,

coordinates of its foci would be:  (h, k±c) where c² = a² - b² and its equation would be:

The dog's running speed of 5 km/hr can be converted to approximately 3.125 mi/hr by multiplying it by the conversion factor of 1 mi/1.6 km. Rounding to the nearest thousandth, the dog can run at about 3.125 mi/hr.

To convert the dog's running speed from kilometers per hour (km/hr) to miles per hour (mi/hr), we need to use the conversion factor of 1.6 km = 1 mi.First, we can convert the dog's speed from km/hr to mi/hr by multiplying it by the conversion factor: 5 km/hr * (1 mi/1.6 km) = 3.125 mi/hr.

However, we need to round the answer to the nearest thousandth (three decimal places). Since the digit after the thousandth place is 5, we round up the thousandth place to obtain the final answer.

Therefore, the dog can run at approximately 3.125 mi/hr.

To prove that 3x ≤ y, assume the opposite, that is, 3x > y, rearrange the inequality substitute x < 2y and simplify, contradict the given condition that x < 2y, therefore, concluding that 3x ≤ y.

Start by assuming the opposite, that is, 3x > y.

From the given inequality,\(7xy \leq 3x^2 + 2y^2,\), we can rearrange to get:
\(7xy - 3x^2 \leq 2y^2\)

We can substitute \(x < 2y\) into this inequality:
\(7(2y)x - 3(2y)^2 \leq 2y^2\)

Simplifying, we get:
\(y(14x - 12y) \leq 0\)

Since y is a real number, this means that either y ≤ 0 or 14x - 12y ≤ 0.

If y ≤ 0, then 3x ≤ y is trivially true.

If 14x - 12y ≤ 0, then we can rearrange to get:
3x ≤ (12/14)y
3x ≤ (6/7)y
3x < y (since we assumed 3x > y)

But this contradicts the given condition that x < 2y, so our assumption that 3x > y must be false.

Therefore, we can conclude that 3x ≤ y.

Based on the given dividend of $4.91, a discount rate of 8.6%, and an expected perpetual growth rate of 3.6%, we would expect the stock's price to be $98.20 today.

To determine the stock's price today, we can use the dividend discount model (DDM), also known as the Gordon growth model. The DDM calculates the present value of all future dividends, taking into account the required rate of return and the expected growth rate.

Let's plug in the values given in your question:

Dividend (D) = $4.91

Discount Rate (r) = 8.6% or 0.086

Perpetual Growth Rate (g) = 3.6% or 0.036

Now we can substitute these values into the formula to calculate the stock's price today:

Stock Price =4.91 - 0.086 = 0.036

Stock Price= 0.086−0.036 = 4.91

Simplifying the denominator:

Stock Price = 4.91/0.05

Stock Price=98.20

To describe the typical quiz scores of the students, a common measure used is the mean, or average, score. The mean is calculated by summing up all the scores and dividing by the total number of scores.

Given its simplicity and simplicity in interpretation, the mean was chosen as a proxy for normal quiz scores. It offers a solitary figure that encapsulates the scores' median. We can figure out the pupils' overall performance on the quiz scores by computing the mean.

It's crucial to keep in mind, though, that outliers or extremely high scores dividing might have an impact on the mean. The mean may not be an accurate representation of the normal results of the majority of students if there are a few students who severely underperform or do very well on the quizzes.

To get a more thorough picture of the distribution of quiz results in such circumstances, it might be beneficial to take into account additional metrics like the median or mode.
