Find the equation of the ellipse

Answer:

B. X

Step-by-step explanation:

the essential rule for a function is that each value of x must have exactly one associated y value.

in other words, if we "feed" the x- value to the function it must be clear what y-value we get as result.

in W 6 has 2 associated y values. no function.

in X all is OK. yes, a function.

in Y again, 6 has 2 associated y values. no function.

in Z 7 has 2 associated y values. no function.

Hence, in response to the provided question, we can say that 2-2 = 0 is not a polynomial expression and S is not a polynomial expression

A polynomial is a mathematical statement made up of parameters and uncertainty that exclusively uses additions, substitutions, multiplications, and nonzero powers of variables. A single uncertain x polynomial is denoted by the expression x2 4x + 7. An formula in mathematics characterized as both a polynomial is constituted of variable (formerly known as different flavored) and coefficients which may be added, deleted, multiplied, and increased to negative integer factors of semi. A polynomial is an algebraic statement having variables and coefficients. Just the operations addition, reduction, multiply, and non-negative integer multipliers are permitted in an expression. These formulas are known as polynomials.

6x³+11x²-5x-12 = (2x-3)(3x+4)(x+1)

3x+4 = 3x+4

2x² + x - 8 = (2x-4)(x+2)

6x +7x³-9x²+13x-12 = 7x³-9x²+(6+13)x-12 = 7x³-9x²+19x-12

3x²-x+3 = 3x²-3x+4x+3 = 3x(x-1)+3(x-1) = (3x+3)(x-1)

2x² + 3x - 4 = (2x-1)(x+4)

2x²+x-3 = (2x-1)(x-3)

2-2 = 0

S = S (not a polynomial expression)

So, the matches are:

6x³+11x²-5x-12 = (2x-3)(3x+4)(x+1)

3x+4 = 3x+4

2x² + x - 8 = (2x-4)(x+2)

6x +7x³-9x²+13x-12 = 7x³-9x²+19x-12

3x²-x+3 = (3x+3)(x-1)

2x² + 3x - 4 = (2x-1)(x+4)

2x²+x-3 = (2x-1)(x-3)

2-2 = 0 is not a polynomial expression

Step-by-step explanation:

Answer: The sales manager, with weekly earnings of $1006.25.

Step-by-step explanation:

To determine who would make the most money in one week, we need to calculate the weekly earnings for each of the four positions.

Let's start with the sales manager, who works 35 hours at a rate of $28.75 per hour:

Weekly earnings for sales manager = 35 hours x $28.75 per hour = $1006.25

Next, let's consider the head mechanic, who works 25 hours. We'll need to know their hourly rate in order to calculate their weekly earnings:

Hourly rate for head mechanic = $35 per hour

Weekly earnings for head mechanic = 25 hours x $35 per hour = $875

Now, let's move on to the assistant mechanic, who works 30 hours:

Hourly rate for assistant mechanic = $20 per hour

Weekly earnings for assistant mechanic = 30 hours x $20 per hour = $600

Finally, let's consider the front desk clerk, who works 40 hours:

Hourly rate for front desk clerk = $15 per hour

Weekly earnings for front desk clerk = 40 hours x $15 per hour = $600

Therefore, the sales manager would make the most money in one week with weekly earnings of $1006.25.

Answer: Sales Manager

Step-by-step explanation:

Let's calculate the total pay for each worker:
Sales manager: $28.75 per hour x 35 hours = $1,006.25

Head mechanic: $32.50 per hour x 25 hours = $812.50
Assistant mechanic: $25.00 per hour x 30 hours = $750.00
Front desk clerk: $20.00 per hour x 40 hours = $800.00

The scale applied to the replica model made by the carpenter is 1:12. This means that 1 inch on the replica model is equal to 12 inches on the full-size table.

What is a replica model?

A replica model in mathematics is a type of modelling technique used to analyse the behaviour of complex systems. It is useful for studying dynamic systems, such as those in physics, engineering, economics, and biology, since it allows for a more accurate analysis of how the system may respond to different inputs.

The scale of the replica model made by the carpenter can be determined by using the ratio of the size of the replica model compared to the size of the full-size table. The ratio of the length of the replica model to the full-size table is 3 inches to 37.5 inches. This can be expressed as a scale by dividing the size of the replica model by the size of the full-size table.

In this example, 3 inches divided by 37.5 inches is equal to 0.08. This means that the scale of the replica model is 1:12, meaning 1 inch on the model is equal to 12 inches on the full-size table. This means that the carpenter used a 1:12 scale when making the replica model of the table.

In conclusion, the scale applied to the replica model made by the carpenter is 1:12. This means that 1 inch on the replica model is equal to 12 inches on the full-size table. This ratio can be determined by taking the ratio of the size of the replica model compared to the size of the full-size table.

According to the given information, the ratio P:O:R is 2√3 : 1 : 2 in its simplest form.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as 1 : 3 (for every one boy there are 3 girls).

Since p:q:r = √3:1:1, we can write:

p = √3x

q = x

r = x

where x is a common factor.

We can see that triangle ABC is a 30-60-90 triangle with angle A = 60 degrees, and that angle BOC is a right angle. Therefore, we can use the ratios of sides in a 30-60-90 triangle to find the values of P, O, and R:

P = AB = p = √3x

O = BC/2 = q/2 = x/2

R = AC = r = x

Therefore, the ratio P:O:R is:

P:O:R = √3x : x/2 : x

We can simplify this ratio by multiplying all terms by 2 to get rid of the fraction:

2√3x : x : 2x

We can further simplify by dividing all terms by x:

2√3 : 1 : 2

Therefore, according to the given information, the ratio P:O:R is 2√3 : 1 : 2 in its simplest form.

Therefore, the measure of angle ABC is 35 degrees.

In geometry, a circle is a two-dimensional shape that is defined as the set of all points in a plane that are equidistant from a fixed point called the center. The distance between the center and any point on the circle is called the radius of the circle. A circle has many properties, such as diameter (a line segment passing through the center and having endpoints on the circle), circumference (the distance around the circle), and sector (a region bounded by two radii and an arc of the circle). The circle is one of the most important and frequently studied shapes in geometry and has many applications in mathematics, science, and everyday life.

Here,

Since chord AB is congruent to chord CB, it follows that they subtend congruent angles at the center of the circle.

Therefore, angle AOC is congruent to angle COB.

The sum of the angles at the center of the circle is 360 degrees, so we can find the measure of angle AOC as:

360° - 70° = 290°

Since angles AOC and COB are congruent, they must each measure half of 290°:

290° / 2 = 145°

Finally, angle ABC is an inscribed angle that subtends arc AC. Its measure is half of the measure of arc AC:

Answer: C

Step-by-step explanation:

Every x value can only have one specific y value. You will have to perform the vertical line test. Basically grab a ruler and  slide it across your graphs vertically ( drag the ruler upright from left to right). Look at your x intercepts and their specific y intercepts.

For A, it continously crosses over so it is not a function. For B, it is always crossing over 2 times so it is not a function. For C, every x intercept has a specific y value therefore it is a function. It crosses over at one point only. For D, the vertical is always crossing over 2 times therefore it will not be a function.

Answer:

C.

Step-by-step explanation:

If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

The vertical parabola is the only graph here that will only touch the graph at one point, so it is the only function.

To calculate the total cost of John and his family's meal (including tip and tax), we can follow these steps:

Calculate the tip amount by multiplying the bill amount by 20% (or 0.2): 65.00 x 0.2 = 13.00

Add the tip amount to the bill amount to get the subtotal: 65.00 + 13.00 = 78.00

Calculate the tax amount by multiplying the subtotal by 7% (or 0.07): 78.00 x 0.07 = 5.46

Add the tax amount to the subtotal to get the total cost: 78.00 + 5.46 = $83.46

Therefore, the total cost of John and his family's meal (including tip and tax) was $83.46.

To calculate the price of the suede jacket with a 20% discount and 8% tax, we can follow these steps:

Subtract the discount amount from the original price to get the sale price: 250 - 50 = $200

Calculate the tax amount by multiplying the sale price by 8% (or 0.08): 200 x 0.08 = 16

Add the tax amount to the sale price to get the total price: 200 + 16 = $216

Therefore, the total price of the suede jacket with a 20% discount and 8% tax is $216.

To calculate the sale price of the bracelet with a 25% discount and 7% tax, we can follow these steps:

Calculate the amount of the discount by multiplying the regular price by 25% (or 0.25): 44 x 0.25 = 11

Subtract the discount amount from the regular price to get the sale price: 44 - 11 = $33

Calculate the tax amount by multiplying the sale price by 7% (or 0.07): 33 x 0.07 = 2.31

Add the tax amount to the sale price to get the total price: 33 + 2.31 = $35.31

Therefore, the sale price of the bracelet with a 25% discount and 7% tax is $35.31.

Angle M is 147 degrees.

A triangle is a geometric shape that consists of three line segments connected end-to-end to form a closed shape. These line segments are called sides, and the points where the sides meet are called vertices. The sum of the three interior angles of a triangle is always 180 degrees, and the length of each side must be less than the sum of the other two sides. Triangles can be classified based on the length of their sides and the size of their angles. For example, a triangle with all three sides of equal length is called an equilateral triangle, while a triangle with two sides of equal length is called an isosceles triangle. Triangles are used in many areas of mathematics, as well as in physics, engineering, and other sciences, to model and solve problems.

Since triangles XYZ and LMN are congruent, corresponding angles are congruent. Therefore, angle LMN = angle XYZ = 33 degrees.

To find angle NML, we use the fact that the sum of the angles in a triangle is 180 degrees. We have:

angle LNM + angle NML + angle MLN = 180 degrees

Substituting the given values, we get:

124 + angle NML + 33 = 180

Simplifying and solving for angle NML, we get:

angle NML = 180 - 124 - 33 = 23 degrees

Therefore, angle M is the exterior angle of triangle LMN at vertex N, which is equal to the sum of the remote interior angles. We have:

angle M = angle LNM + angle NML = 124 + 23 = 147 degrees

The function value of g[f(-1)] when f(x) = 2x² + 4x and g(x)=-3x-1 is 5.

In mathematics, a function is a rule that assigns each element from a set (called the domain) to a unique element from another set (called the range or codomain). It is a way of describing the relationship between two sets of numbers. The input values of a function are called the independent variable or argument, and the output values are called the dependent variable. The most common way to represent a function is by using an equation.

Here,

To evaluate g[f(-1)], we need to first find f(-1), then use that value as the input to the function g.

We have:

f(x) = 2x² + 4x

So, to find f(-1), we substitute -1 for x:

f(-1) = 2(-1)² + 4(-1)

= 2 - 4

= -2

Now that we have f(-1) = -2, we can evaluate g[f(-1)] by substituting -2 for x in the function g:

g[f(-1)] = g[-2]

= -3(-2) - 1

Part 1 - Circumcenter: The point where all three sides of the triangle meet and intersect, also the center of the circle that passes through all three vertices of the triangle.

Intersect is an operation used in mathematics and computing to determine the common elements of two or more sets. It is usually written as a symbol (∩) and is used to return the set of all elements that are in both sets. For example, if A is the set of all even numbers and B is the set of all prime numbers, then A ∩ B will return the set of all prime even numbers.

- Orthocenter: The point where the three altitudes of the triangle intersect.
- Centroid: The point where the three medians of the triangle intersect.

Part 3: The three centers of the triangle (circumcenter, orthocenter, and centroid) can all be constructed using a straightedge and compass. The circumcenter is located at the intersection of the three sides, the orthocenter is located at the intersection of the three altitudes, and the centroid is located at the intersection of the three medians.
