Answer:

[tex]d^{2}[/tex] - 16.

Step-by-step explanation:

To solve for the product of (d + 4) and (d - 4), we can use the FOIL method.

This means we multiply the first terms, then the outer, then the inner, and finally the last terms, then we add all the products together.

So, (d + 4) (d - 4) can be expanded like this:

Adding all of them together, we get: [tex]d^{2}[/tex] - 4d + 4d - 16, which simplifies to [tex]d^{2}[/tex] - 16.

Therefore, (d + 4)(d - 4) = [tex]d^{2}[/tex] - 16.

Answer:

Rounding to the nearest hundredth of a foot, the change in altitude is approximately 514.77 feet.

Step-by-step explanation:

To solve this problem, we can use trigonometry. The angle of climb is 15 degrees, which means that the ratio of the change in altitude to the horizontal distance traveled is the tangent of 15 degrees:

tan(15°) = change in altitude / horizontal distance

We can rearrange this equation to solve for the change in altitude:

change in altitude = horizontal distance x tan(15°)

Substituting the given values, we get:

change in altitude = 2 miles x tan(15°)

We can convert the distance to feet by multiplying by 5280:

change in altitude = 2 miles x 5280 feet/mile x tan(15°)

Using a calculator, we get:

change in altitude ≈ 514.77 feet

Rounding to the nearest hundredth of a foot, the change in altitude is approximately 514.77 feet.

Answer:

approx 20% of the department faculty have 20 or more years of service

Step-by-step explanation:

To find the percentage of the department faculty with 20 or more years of service, we need to add up the number of faculty members in the "20-24.9" and "25 or more" year categories, since anyone with 20 or more years of service would fall into one of these categories.

Looking at the histogram, we see that there are 24 faculty members in the "20-24.9" year category, and an additional 4 in the "25 or more" year category. Therefore, the total number of faculty members with 20 or more years of service is 24 + 4 = 28.

To calculate the percentage of faculty members with 20 or more years of service, we need to divide this number by the total number of faculty members in the department, which we can find by adding up the heights of all the bars in the histogram. Based on the heights of the bars in the histogram, we can estimate that the total number of faculty members is approximately 140.

Therefore, the percentage of faculty members with 20 or more years of service is:

(28/140) x 100% = 20%

So, approximately 20% of the department faculty have 20 or more years of service.

a. ΔEGF~ΔGHF~ΔEHG are the similarities between the three right triangles.

b. HF/HG = GH/EH; EF/EG = EG/EH

According to the similar right triangle theorem, if a right triangle's altitude is drawn from its right angle, two similar right triangles are created, and both similar right triangles are identical to the original right triangle. All three right triangles are essentially the same.

Similar triangles contain three pairs of comparable side lengths that are proportionate to one another, or whose ratios are identical.

The corresponding side lengths are taken into account when constructing similarity statements.

A similarity assertion linking the three right triangles is thus: ΔEGF~ΔGHF~ΔEHG.

Step-by-step explanation:

(Let t = total number of races)

Each race costs $3.50, so the total cost of racing t times is 3.50 × t or 350t. Douglas wants to have at least $7.75 left on his card, so an inequality to represent this would look like this:

Solving this inequality, we get:

Or we can do this.

Therefore, Douglas can race the go-karts 3 times and still have at least $7.75 left on his card to play arcade games.

After addressing the issue at hand, we can state that We know that when  function x = 0, y = b because the function has the form y = mx + b.

Mathematicians investigate numbers and their varieties, equations and adjacent tissues, shapes but instead their locations, and potential locations for these things. The term "function" refers to the relationship here between set of inputs, each with its own output. A function is a relationship of both inputs and outputs in which each input results in a single, distinct production. Each function has its own domain, codomain, or scope. The letter f is commonly used to denote functions (x). An x represents entry. On functions, each capabilities, so several capabilities, in capabilities, and on operations are the four major types of accessible functions.

We know that the function represented by the table of values has the form y = mx + b because it is linear, where y represents the distance from Nate's starting point and x represents the time he has been travelling.

The rate of change is known to be 50 miles per hour. This means that Nate's distance from his starting point increases by 50 miles for every hour he travels. In other words, m equals 50.

Use SAS congruency; AD=DC, and they both share side BD. Also, BD is the perpendicular bisector to AC, so it also forms 2 right angles. Proof using SAS.

Or, if you don’t know SAS congruency, you may use SSS congruency;

Use the Pythagorean theorem. Side length AB^2 = AD^2 + BD^2
BC^2 = DC^2 + BD^2.

What is Lagrange multipliers ?

Lagrange multipliers is a method used in optimization problems to find the maximum or minimum value of a function subject to one or more constraints. The method involves introducing a Lagrange multiplier, which is a scalar variable, to the objective function and the constraint(s). This forms the Lagrangian function, which is then optimized with respect to the original variables and the Lagrange multiplier.

To minimize the cost C = x₁² + x₂²

We can use the method of Lagrange multipliers to solve this problem. Let's define the Lagrangian function L as:

L(x₁, x₂, λ) = x₁²+ x₂² + λ(400 - 5x₁²- 8x₁x₂ - 15x₂²)

Taking partial derivatives of L with respect to x₁, x₂, and λ, we get:

∂L/∂x₁ = 2x₁ - 10λx₁ - 8λx₂ = 0

∂L/∂x₂ = 2x₂ - 30λx₂ - 8λx₁ = 0

∂L/∂λ = 400 - 5x₁² - 8x₁x₂ - 15x₂² = 0

Solving these equations simultaneously, we get:

x₁ = 4

x₂ = 8

λ = 1/20

Hence, the firm should produce a combination of x₁ = 4 and x₂ = 8 to minimize the cost of C = x₁² + x₂² while satisfying the production quota of 400.

Answer:

To make the piano player's practice seem consistent, adjust the Y-axis scale, use a line graph, and add a trend line or moving average.

Step-by-step explanation:

To adjust the graph to make it seem like the piano player is pretty consistent in practicing, we can make the following changes:

Adjust the scale of the Y-axis to make the differences in the average practice times appear smaller. For example, we can change the range of the Y-axis from 0-15 to 8-14, since all the data points fall within this range. This would compress the data vertically and make the differences in the average practice times appear smaller.

Use a line graph instead of a bar graph to better show the trend of the data over time. This would allow us to see any patterns or trends in the average practice times over the course of the year.

Add a trend line or moving average to the graph to show the overall trend in the data and smooth out any fluctuations. This would further emphasize the consistency in the piano player's practice habits.

By making these adjustments, the graph would show that the piano player is consistently practicing for around 10-11 hours per week throughout the year, with some slight variations. This would convey the message that the piano player is dedicated and consistent in their practice habits.

The correct option is 312 cm² as the area of the composite figure calculated to be equal to 312 square centimeters.

The composite figure can be observed to be made up of two identical triangle and a rectangle, so we shall calculate for the area of one triangle, multiply the result by 2, and add the area to the area of the rectangle to get the total area of the composite figure as follows:

area of one of the triangle = 1/2 × 12 cm × 10 cm

area of one of the triangle = 6 cm × 10 cm

area of one of the triangle = 60 cm²

area of one of the two triangle = 2 × 60 cm²

area of one of the two triangle = 120 cm²

area of the rectangle = 16 cm × 12 cm

area of the rectangle = 192 cm²
