HELP ASAPPP!!! Solve the triangle

We can write the quadratic equation as -

y = - (x - 25)² + 625

The general form of a quadratic equation is -

y = ax² + bx + c

where -

a, b and c are constants.

Given is that Sameen wants to build a fence around a rectangular area of her yard. The graph shows the area {y} in square feet that she can surround with the fencing that she has, where the breadth is width {x} in feet of the rectangle.

The given coordinates on the parabola are -

(8, 336)

(42, 336)

(25, 625)

Here, the point (25, 625) represents the vertex (h, k) of the parabola.

We can write the equation of parabola as -

y = a(x - h)² + k

y = a(x - 25)² + 625

For the point (8, 336), we can write -

336 = a(8 - 25)² + 625

336 - 625 = a(8 - 25)²

a(8 - 25)² = - 289

a(- 17)² = -289

a = -289/289

a = -1

So, we can write the quadratic equation as -

y = - (x - 25)² + 625

Therefore, we can write the quadratic equation as -

y = - (x - 25)² + 625

What is an expression?

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation.

To evaluate the expression (1 - 1i) + (3 + 2i), we simply add the real parts and the imaginary parts separately -

(1 - 1i) + (3 + 2i)

= (1 + 3) + (-1i + 2i)

Answer:(4 + 3) x 2

Step-by-step explanation:

Vesi snowboards 4 hours before lunch and 3 hours after lunch each day, so the total time she spends snowboarding each day is:

4 + 3 = 7 hours

The question is asking how many hours Vesi snowboarded in 2 days, so we need to multiply the daily total by 2:

7 x 2 = 14

Therefore, the expression that represents this real-world situation is:

B. (4 + 3) x 2 = 14.

Option A adds 2 hours which is not correct as Vesi snowboards 7 hours each day, not 2 hours. Option C multiplies and divides, which is not necessary in this case. Option D multiplies and subtracts, which is also not correct.

NO || PR using the converse of the Triangle Proportionality Theorem are not parallel.

The Triangle Proportionality Theorem states that if a line is parallel to one side of a triangle and intersects the other two sides, then it divides those sides proportionally.

Conversely, if a line divides two sides of a triangle proportionally, then it is parallel to the third side.

In this problem, we are given a right triangle NQM, where line PR intersects the sides NM and QM at points P and R, respectively. We are also given that NM = 16, PM = 12, RM = 6, and QR = 8. We want to verify that NO || PR.

To do this, we will use the converse of the Triangle Proportionality Theorem. We know that PR divides NM proportionally, so we need to show that it also divides QM proportionally.

Using the ratios of corresponding side lengths of similar triangles, we can write:

PM / RM = PN / RN

Substituting the given values, we get:

12 / 6 = PN / (16 - 6)

2 = PN / 10

PN = 20

Similarly, we can write:

QR / RM = QN / RN

Substituting the given values, we get:

8 / 6 = QN / (16 - 6)

4 / 3 = QN / 10

QN = 40 / 3

Now we can check if PR divides QM proportionally:

PM / QN = 12 / (40 / 3) = 9 / 5

PN / RM = 20 / 6 = 10 / 3

Since these ratios are not equal, we can conclude that PR does not divide QM proportionally.

Therefore, by the converse of the Triangle Proportionality Theorem, we can conclude that NO is not parallel to PR.

the width of the garden is approximately 6.77 feet, and the length is approximately 11.77 feet (since it is 5 feet more than the width).

what is rectangle?

A rectangle is a four-sided polygon with opposite sides that are parallel and equal in length.

Let's denote the width of the garden by x. Then, according to the problem statement, the length of the garden is x + 5.

The total width of the garden and the walkway is x + 2(3) = x + 6, and the total length is x + 5 + 2(3) = x + 11.

The area of the garden itself is x(x + 5), and the area of the garden and the walkway is (x + 6)(x + 11).

The area of the walkway is the difference between the two: (x + 6)(x + 11) - x(x + 5) = 210.

Expanding and simplifying this expression, we get:

x^2 + 17x - 135 = 0

We can solve for x using the quadratic formula:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

In this case, a = 1, b = 17, and c = -135, so we have:

x = (-17 ± sqrt(17^2 - 4(1)(-135))) / 2(1)

x = (-17 ± sqrt(769)) / 2

We can discard the negative solution, so we have:

x = (-17 + sqrt(769)) / 2

x ≈ 6.77

Therefore, the width of the garden is approximately 6.77 feet, and the length is approximately 11.77 feet (since it is 5 feet more than the width).

The amount of snow that fell each week was 2 units (assuming the units are consistent with the original scenario.

Snowfall measurement is the process of determining the amount of snow that falls at a particular location during a specific period of time. Accurate snowfall measurement is important for a variety of reasons, including transportation safety, weather forecasting, and water resource management.

If the same amount of snow fell the following winter, but the same amount of snow fell each week, and there were the same number of weeks, then we need to divide the total amount of snow by the number of weeks to find the amount of snow that fell each week.

Looking at the diagram, we can estimate the total amount of snow that fell by counting the number of asterisks (*) in the diagram. There are 8 asterisks, which represent the total amount of snow that fell over the winter.

Since there are 4 weeks (the same number of weeks as the original scenario), we can divide the total amount of snow by 4 to find the amount of snow that fell each week:

Total amount of snow = 8 asterisks

Amount of snow that fell each week = Total amount of snow / Number of weeks

= 8 / 4

= 2

Therefore, the amount of snow that fell each week was 2 units (assuming the units are consistent with the original scenario).

A degree of operating leverage of 4.00 means that a 1% change in sales will result in a 4% change in net operating income. Thus, option D is correct.

The degree of operating leverage (DOL) formula is:

DOL = Contribution Margin / Net Operating Income

We can calculate the contribution margin using the CM ratio:

Contribution Margin = Sales x CM ratio

Contribution Margin = $200,000 x 0.60

Contribution Margin = $120,000

Now we can calculate the DOL:

DOL = Contribution Margin / Net Operating Income

DOL = $120,000 / $30,000

DOL = 4.00

Therefore, the company's degree of operating leverage is 4.00.

The answer is (D) 4.00.

Step-by-step explanation:

Identify the relevant values from the problem statement:

Net operating income = $30,000

Fixed expenses = $90,000

Sales = $200,000

CM ratio = 60%

Calculate the contribution margin using the CM ratio:

Contribution Margin = Sales x CM ratio

Contribution Margin = $200,000 x 0.60

Contribution Margin = $120,000

Use the contribution margin and net operating income to calculate the degree of operating leverage:

DOL = Contribution Margin / Net Operating Income

DOL = $120,000 / $30,000

DOL = 4.00

Interpret the result:

A degree of operating leverage of 4.00 means that a 1% change in sales will result in a 4% change in net operating income. This indicates that the company has a high degree of operating leverage, which means that it is more sensitive to changes in sales volume. In other words, small changes in sales can have a big impact on the company's profitability.

The location of the region's centroid is (0, 2/5).

What does the region border by the curves' centroid look like?

We must first determine the limits of integration and the formulas for the x-coordinate and y-coordinate of the centroid in order to determine the centroid of the area enclosed by the curves y=2-x2 and y=x.

We shall integrate across the range [-1,1] since the curves intersect at (1,1) and (-1,1).

We must assess the following integral in order to determine the centroid's x-coordinate:

x' = (1/A) ∫[a,b] xf(x) dx

Where: A is the region's area (which we can find by integrating the difference between the two curves).

A = ∫[a,b] (f(x) - g(x)) dx

In this case, f(x) = 2 - x² and g(x) = x, so

A = ∫ [-1,1] (2 - x² - x) dx

= [2x - (1/3)x³ - (1/2) x²] | from -1 to 1

= (4/3)

Now we can evaluate the x-coordinate of the centroid:

x' = (1/A) ∫ [-1,1] x*(2-x²-x) dx

= (1/ (4/3)) ∫ [-1,1] (2x - x³ - x²) dx

= (3/4) [(x²/2) - (1/4) x⁴ - (1/3) x³] | from -1 to 1

= 0

Hence, the x-coordinate of the centroid is 0.

To find the y-coordinate of the centroid, we need to evaluate the following integral:

y' = (1/A) ∫[a,b] (1/2) [f(x)² - g(x)²] dx

y' = (1/ (4/3)) ∫ [-1,1] (1/2) [(2-x²) ² - x²] dx

= (3/4) [(8/15) x⁵ - (2/3) x³ + (1/2) x] | from -1 to 1

= (2/5)

Hence, the y-coordinate of the centroid is 2/5.

Therefore, the centroid is (0,2/5).

=> x/3 = 50 => x = 150

=> y/5 = 50 => y = 250

=> z/10 = 50 => z = 500

The ratio table - 2

Feet    100

Hours   1       2     4     6  

The ratio of feet/ second = 100/1 = 100

Let a, b, and c be the values

=> a/2 = b/4 = c/6 = 100

=> a/2 = 100 => a = 200

=> b/4 = 100 => b = 400

=> c/6 = 100 => c = 600

Therefore,
