How to identify the equation of the Ellipse?

The general form and the standard form of the ellipse are:

- The general form is: Ax² + Bxy + Cy² + Dx + Ey + F = 0

- The standard form is: (x - h)²/a² + (y - k)²/b² = 1

1) x²/3² + (y - 2)²/2² = 1

Expanding gives:

x²/9 + (y - 2)²/4 = 1

Multiply through by 36 to get:

4x² + 9(y - 2)² = 36

Expand bracket to get:

4x² + 9y² - 36y + 36 = 36

Subtract 36 from both sides to get:

2) (x + 7)²/7² + y²/6² = 1

(x + 7)²/49 + y²/36 = 1

Multiply through by 1764 to get:

36(x + 7)² + 49y² = 1764

Expand bracket to get:

36x² + 504x + 1764 + 49y² = 1764

Subtract 1764 from both sides to get:

36x² + 504x + 49y² = 0

3) x²/6² + (y + 4)²/4² = 1

x²/36 + (y + 4)²/16 = 1

Multiply through by 576 to get:

16x² + 36(y + 4)² = 576

Expand bracket to get:

16x² + 36y² + 288y + 576 = 576

Subtract 576 from both sides to get:

16x² + 288y + 36y² = 0

The general form of x²/6² + (y + 4)²/4² = 1  is 16x² + 288y + 36y² = 0

4)  (x - 3)²/3² + y²/5² = 1

(x - 3)²/9 + y²/25 = 1

Multiply through by 225 to get:

25(x - 3)² + 9y² = 225

Expand the bracket power to get:

25x² - 150x + 225 + 9y² = 225

Subtract 225 from both sides

25x² - 150x + 9y² = 0

Answer/Step-by-step explanation:

A cook has 6 onions that have a total mass of 900 grams and 8 apples that have a total mass of 1 kilogram. All onions are the same size, and all apples are the same size. Which has the greater mass, an onion or an apple? Explain.

1. Underline the question you need to answer.

See above

2. What units are used in the problem?

The units used are grams and kilograms.

3. What should you do before comparing the masses?

Before comparing masses you should make sure that the apples and onions unit's are both the same.

4. How many kilograms is 900 grams?

0.9 kilograms

---

This is solved by creating a proportion:

Proportion is a mathematical comparison between two ratios (or fractions) and are equal to each other.

We know that 1 kilogram = 1000 grams

You can remember this by the fact that the prefix kilo = 1000

Your proportion would be set up as:

1 kilogram/ 1000 grams = x kilograms/ 900 grams

we can multiply 900 grams on both sides to isolate x (get x by itself)

900 grams * 1 kilogram/ 1000 grams = 900 grams * x kilograms/ 900 grams

simplified it would look like:

900 kg/1000 = x kg

x = 0.9 kg

So 0.9 kilograms is equal to 900 grams.

---

5. How many grams is 1 kilograms?

There are 1000 grams in 1 kilograms.

6. What do you need to do find the mass of 1 onion and 1 apple? Explain.

To find the mass of one onion you must divide the total mass of onions (900 grams) by 6, and you get that one onion is equal to 150 grams. To find the mass of one apple you can first convert its total mass (1 k) to grams, which equals 1000 grams. Now you can take its total mass in grams and divide it by 8. You get that one apple is equal to 125 grams.

Which has the greater mass, an onion or an apple? Explain

An onion has a greater mass than the apple because one onion has mass of 150 grams, which is greater than one apple's mass of 125 grams.

Step-by-step explanation:

The diagram shows two triangles, ΔABC and ΔDEF.

The tick marks on the sides of the triangles show that two corresponding sides are congruent:

AB ≅ EDBC ≅ EF

In similar triangles:

Corresponding angles are the same size.Corresponding sides are always in the same ratio.

As the diagram does not include any information about the interior angles or the length of the third side, we cannot determine if the triangles are similar.

The value of side length x (DF) in the triangle is 4.

What is the value of x?

The figures in the image is that of two similar triangle.

Triangle ABC is similar to triangle DEF.

From the diagram:

Leg 1 of the smaller triangle DE = 5

Leg 2 of the smaller triangle DF = x

Leg 1 of the larger triangle AB = 30

Leg 2 of the larger triangle AC = 24

To find the value of x, we take the ratio of the sides of the two triangle since they similar:

Hence:

Leg DE : Leg DF = Leg AB : Leg AC

Plug in the values:

5 : x = 30 : 24

5/x = 30/24

Cross multiplying, we get:

Mushrooms have a yield factor of 90%. A 15 pound flat of mushrooms cost $29.85. What is the ap,cost per pound?

Answers

Answer: $2.21

Step-by-step explanation:

To calculate the cost per pound of mushrooms, we need to use the yield factor given in the question. The yield factor tells us the percentage of the total weight of the mushrooms that can be used for cooking or sale. Here, the yield factor is 90%, which means that 90% of the weight of the mushrooms can be used. Let's begin with the calculation:

First, we need to find out how much of the weight of the mushrooms is usable: 90% of 15 pounds = 0.9 x 15 = 13.5 pounds

Now, we can find out the cost per pound of the mushrooms:

Cost per pound = Total cost / Total usable weight

Total cost = $29.85

Total usable weight = 13.5 pounds

Therefore, the cost per pound of mushrooms = $29.85 / 13.5 pounds ≈ $2.21 per pound

Therefore, the cost per pound of mushrooms is $2.21 per pound.

if f(x)= 1 over 9x -2, what is f^-1(x)?

Answers

Therefore, the inverse function f^(-1)(x) of f(x) = 1/(9x - 2) is f^(-1)(x) = (2x + 1)/(9x).

To find the inverse function of f(x) = 1/(9x - 2), denoted as f^(-1)(x), we follow these steps:

   Replace f(x) with y: y = 1/(9x - 2).

   Swap the variables x and y: x = 1/(9y - 2).

   Solve the equation for y. Begin by multiplying both sides of the equation by (9y - 2): x(9y - 2) = 1.

   Distribute the x on the left side: 9xy - 2x = 1.

   Add 2x to both sides: 9xy = 1 + 2x.

   Divide both sides by 9x: y = (1 + 2x)/(9x).

   Simplify the expression: y = (2x + 1)/(9x).

(3)The full payment required on April 3 to reduce the balance on the invoice to zero is $48,190.38.

The calculation of the full payment required takes into account the terms specified on the invoice. In the first scenario, the invoice terms are 2/10, n/30, which means that a 2% discount can be applied if payment is made within 10 days, otherwise, the full payment is due within 30 days.

Therefore, the full payment is calculated as the invoice amount minus the discount. Similarly, for the second scenario, the invoice terms are 3/10, 2/20, 1/30, and n/50, which involve multiple discounts based on different payment dates.

The full payment is determined by applying the applicable discounts. Finally, in the third scenario, the invoice terms are ROG (Receipt of Goods), and the full payment is due by April 15. Hence, the full payment required on the specified date is calculated.

A swimming pool is 8 m long, 6 m wide and 1.5 m deep. The water-resistant paint needed for the pool costs 6 dollars per square meter. How much will it cost to paint all the interior surfaces of the pool?

Answers

It will cost $1080 to paint all the interior surfaces of the pool.

6. & 7. The triangles have sides of 8, 8, and 10 cm, and an area of 24 square cm. The remaining areas are 18 and 12 square cm, respectively.

Triangle with Sides 8, 8, and 10 cm: First, we must calculate the area of the whole triangle, which has sides of 8, 8, and 10 cm. Using the Heron's formula, we can find the area of a triangle given the lengths of its sides: A = √(s(s - a)(s - b)(s - c)), where s = (a + b + c)/2 is the semi perimeter of the triangle.

A = √(13(13 - 8)(13 - 8)(13 - 10)) = √(13(5)(5)(3)) = √(2925) = 15√(65) ≈ 59.17 square cm. Next, we can calculate the areas of the shaded regions as follows: Area of Shaded Region 1 = Area of Whole Triangle - Area of Small Triangle Area of Shaded Region 1 = 15√(65) - 18 = 15√(65) - 6√(65) = 9√(65) ≈ 27.94 square cm.

Area of Shaded Region 2 = Area of Whole Triangle - Area of Large Triangle Area of Shaded Region 2 = 15√(65) - 24 = 3√(65) ≈ 7.74 square cm.7.

A swimming pool has the dimensions 8 m (length), 6 m (width), and 1.5 m (depth). The total area to be painted is the sum of the areas of the floor, the ceiling, and the walls of the pool. Since the pool is rectangular in shape, we can break it down into six different parts: the top and bottom surfaces, and the four vertical surfaces.

Let's begin by calculating the area of the floor, which has dimensions of 8 m by 6 m:Area of Floor = length x width = 8 x 6 = 48 square meters.

Next, we can calculate the area of the ceiling, which has the same dimensions as the floor: Area of Ceiling = length x width = 48 square meters. Since the pool has a depth of 1.5 m, the total height of the vertical surfaces is 1.5 x 2 = 3 m (since there are two vertical surfaces on each side of the pool).

Thus, the total area of the four vertical surfaces is given by: Area of Walls = perimeter x height = 2(length + width) x height = 2(8 + 6) x 3 = 84 square meters.

Finally, we can calculate the total area to be painted by adding up the area of the floor, ceiling, and walls: Total Area = Area of Floor + Area of Ceiling + Area of Walls Total Area = 48 + 48 + 84 = 180 square meters.

The cost of paint is given as $6 per square meter, so we can calculate the total cost of painting the pool as follows: Cost = Total Area x Cost per Square Meter Cost = 180 x $6 = $1080. Therefore, it will cost $1080 to paint all the interior surfaces of the pool.

(x+6/7)^2+(y+4)^2=49/4 find three points of this circle

Answers

To find three points on the circle defined by the equation (x+67)2+(y+4)2=494(x+76​)2+(y+4)2=449​, we can manipulate the equation to extract the center and radius information.

Expanding the equation, we have:

x2+127x+3649+y2+8y+16=494x2+712​x+4936​+y2+8y+16=449​

Combining like terms, we get:

x2+y2+127x+8y+1149=0x2+y2+712​x+8y+4911​=0

Comparing this equation to the standard form of a circle, (x−a)2+(y−b)2=r2(x−a)2+(y−b)2=r2, we can identify the center (a,b)(a,b) as −67,−4−76​,−4 and the radius rr as 7227​.

Now we can find three points on the circle by substituting different angles into the equation. For example:

   At 00 degrees: (−6/7+72),−4(−6/7+27​),−4 or (11/14,−4)(11/14,−4)

   At 9090 degrees: −6/7,−4+72−6/7,−4+27​ or −6/7,1/2−6/7,1/2

   At 180180 degrees: (−6/7−72),−4(−6/7−27​),−4 or (−55/14,−4)(−55/14,−4)

Therefore, three points on the circle are (11/14,−4)(11/14,−4), (−6/7,1/2)(−6/7,1/2), and (−55/14,−4)(−55/14,−4).

If don has three more than three times the number of marbles mark how many does each boy have to sell if the total number of marbles is 99 

Answers

Answer:

Don has 75 marbles to sell,  Mark has 24 marbles to sell

Step-by-step explanation:

Don has three more than three times the number of marbles Mark has

Now this information can be put into equation form

(In this equation, D = Don and M = Mark)

Equation:

D = 3M + 3

The total number of marbles is 99

This represented as an equation is:

D + M = 99

Now, with both of these equations, it is now a system of equations. Now you must solve the system of equations.

Substitute the value of D from the first equation into the second equation

(3M + 3) + M = 99

4M + 3 = 99

4M = 99 - 3

4M = 96

M = 96/4

M = 24

Now you can substitute the value of M back into the first equation to find the value of D

D = 3(24) + 3

D = 72 + 3

D = 75

This shows that Don has 75 marbles to sell, and Mark has 24.

help please!!!!!!!!!!

Answers

Answer:

The interval from -12 to -7

The interval from 6 to 12.

Step-by-step explanation:

The equation is log(x + 9) + log(x 9) = log[(x + 9)(x 9)]. = log(x² − 81)

Here is the equation:

log(x² - 81) = 0.47712

This can be expressed in exponential form:

x² - 81 = 10^(0.47712)

x² = 81 + 3.02343

x² = 84.02343

x ≈ ± 9.1658

The answers are therefore x -9.1658 and x 9.1658.

These intervals are where these solutions occur:

The answer, x -9.1658, can be found in the range from -12 to -7.

- The answer x = 9.1658 is found in the range of 6 to 12.

The appropriate choices are:

- The range between -7 and -12; - The range between 6 and 12.

The calculated value of x in the figure is 12

How to calculate the value of x in the figure

From the question, we have the following parameters that can be used in our computation:

The figure

The scale is given as

A : B = 8 : 9

So, we have

48 : 2x + 30 = 8 : 9

Next, we have

(2x + 30)/48 = 9/8

This gives

2x + 30 = 48 * 9/8

2x + 30 = 54

This gives

2x = 24

So, we have

x = 12

Hence, the value of x in the figure is 12

find all the values of c such that the distance from the point (x,8) to the point (2,-4) is exactly 13 units give answer in ascending order

Answers

Therefore, the values of c are 2 + 5 = 7 and 2 - 5 = -3. So, the values of c that satisfy the condition are -3 and 7.

To find the values of c such that the distance from the point (x,8) to the point (2,-4) is exactly 13 units, we can use the distance formula.

The distance formula between two points (x₁, y₁) and (x₂, y₂) is given by:

√((x₂ - x₁)² + (y₂ - y₁)²)

In this case, we have (x₁, y₁) = (x, 8) and (x₂, y₂) = (2, -4). Substituting these values into the distance formula, we get:

√((2 - x)² + (-4 - 8)²) = 13

Simplifying, we have:

√((2 - x)² + (-12)²) = 13

Squaring both sides of the equation to eliminate the square root, we get:

(2 - x)² + (-12)² = 13²

Expanding and simplifying:

(x - 2)² + 144 = 169

(x - 2)² = 169 - 144

(x - 2)² = 25

Taking the square root of both sides, we have:

x - 2 = ±5

Solving for x, we get:

x = 2 ± 5

Which is an exponential decay function
F(x)= 0.2

Answers

The function F(x)=0.2F(x)=0.2 is not an exponential decay function. It is a constant function where the output value is always equal to 0.2, regardless of the input value xx.

An exponential decay function is typically in the form f(x)=a⋅bxf(x)=a⋅bx, where aa and bb are constants and bb is a value between 0 and 1. As xx increases, the exponential decay function decreases exponentially.

For example, an exponential decay function could be f(x)=0.2⋅(0.5)xf(x)=0.2⋅(0.5)x, where the base 0.50.5 represents the decay factor. As xx increases, the value of the function decreases rapidly.

In summary, an exponential decay function follows the pattern of decreasing values as xx increases, while the function F(x)=0.2F(x)=0.2 represents a constant value regardless of the input xx.

(2x-3)(5x squared-2x+7

Answers

Answer: [tex]10x^3-19x^2+20x-21[/tex]

Step-by-step explanation:

This problem is a binomial being multiplied by a trinomial.

We can solve it by multiply each term in the first expression by each term in the second expression and combine like terms.

[tex](2x - 3)(5x^2 -2x + 7)[/tex]

First lets multiply the 2x to the trinomial, (5x^2 - 2x + 7)

2x * 5x^2 = 10x^3

2x * -2x = -4x^2

2x * 7 = 14x

Next lets multiply the -3 to the trinomial (5x^2 - 2x + 7)

-3 * 5x^2 = -15x^2

-3 * -2x = 6x

-3 * 7 = -21

Now put all in order by highest power (Exponent) to lowest (to lowest exponent/ or constant)

[tex]10x^3-4x^2-15x^2+14x+6x-21[/tex]

And lastly, combine like terms:

[tex]10x^3-19x^2+20x-21[/tex]

Your final answer is [tex]10x^3-19x^2+20x-21[/tex]

Solve the quadratic equation by using the square root property.
(2x + 3)2 = 81

Answers

Answer: x = 3 and x = -6

Step-by-step explanation:

the first step is to square root both sides of the equation to get rid of the exponent (2) on the left side of the equation, however lets break it down:

[tex](2x + 3)^2 = 81\\\\[/tex]

81 can be rewritten as 9^2

[tex](2x + 3)^2= 9^2[/tex]

and now lets square root both sides:

[tex]\sqrt{(2x+3)^2} =\sqrt{9^2}[/tex]

The squares (the exponent 2) cancels out with the square root:

2x + 3 = +/- 9

now lets isolate x by subtracting 3 from both sides:

2x + 3 = +/- 9

       -3  -3

2x = -3 +/- 9

2x = -3 + 9

2x = 6

2x = -3 - 9

2x = 12


And after simplifying, you can divide two on both sides:

2x = 6

/2    /2

x = 3

2x = -12

/2    /2

x = -6

x = 3 and x = -6
