Write the equation of this conic section in conic form: 100pts pls

Answers

The equation of the conic section in conic form is (x - 1) = (y + 6)²/4.

To write the equation of the conic section in conic form, we can complete the square to transform the equation into its standard form. Let's start with the given equation:

y² - 4x + 12y + 32 = 0

Rearranging the terms, we have:

y² + 12y - 4x + 32 = 0

To complete the square for the y-terms, we add and subtract the square of half the coefficient of y (which is 6 in this case):

y² + 12y + 36 - 36 - 4x + 32 = 0

Simplifying this, we get:

(y + 6)² - 4x + 4 = 0

Now, rearranging the terms, we have:

(y + 6)² = 4x - 4

Dividing both sides of the equation by 4, we get:

(y + 6)²/4 = x - 1

Finally, we can write the equation in conic form:

(x - 1) = (y + 6)²/4

How to obtain the equivalent expressions?

Equivalent expressions are the expressions that have the same result, hence we must simplify each expression.

The first expression is given as follows:

(4x³ + 7x - 4) - (2x³ - x - 8).

Simplifying the like terms, we have that:

4x³ - 2x³ = 2x³.7x - (-x) = 7x + x = 8x.-4 - (-8) = -4 + 8 = 4.

Hence it is equivalent to expression B.

The second expression is simplified as follows:

[tex](x^4 - 3x^2 + x) + (2x^4 + 4x - 7) = 3x^4 - 3x^2 + 5x - 7[/tex]

The third expression is simplified as follows:

The true options are:

A. If p = a number is negative and q = the additive inverse is positive, the original statement is p → q.

B. If p = a number is negative and q = the additive inverse is positive, the inverse of the original statement is ~p → ~q.

E. If q = a number is negative and p = the additive inverse is positive, the converse of the original statement is q → p.

Option A represents the original statement accurately. It states that if a number is negative (p), then the additive inverse is positive (q). This corresponds to the implication p → q, where the antecedent is p and the consequent is q.

Option B represents the inverse of the original statement. It states that if a number is not negative (~p), then the additive inverse is not positive (~q). This is the negation of the original statement and can be written as ~p → ~q.

Option C represents the converse of the original statement. It states that if the additive inverse is not positive (~q), then the number is not negative (~p). The converse swaps the positions of the antecedent and consequent, resulting in ~q → ~p.

Options D and E are not true. Option D represents the contrapositive of the original statement, which would be if the additive inverse is not positive (~q), then the number is not negative (~p). However, the contrapositive should have the negation of both the antecedent and the consequent, so the correct contrapositive would be ~q → ~p.

Option E incorrectly represents the converse by stating that if the additive inverse is negative (q), then the number is positive (p), which is not an accurate representation of the converse.

In summary, the true options are A, B, and C, as they accurately represent the original statement, its inverse, and its converse, respectively.

Adjust net income of $98,500 for changes in operating assets and liabilities to arrive at net cash flow from operating activities.

Answers

The net cash flow from operating activities would be $100,800.

What is the net cash flow from operating activities?

Change in accounts receivable:

= $20,900 - $20,000

= $900

Change in inventory:

= $61,800 - $62,500

= -$700

Change in accounts payable:

= $19,700 - $18,600

= $1,100

Change in dividends payable:

= $24,000 - $22,000

= $2,000

Change in operating assets and liabilities:

= Change in accounts receivable + Change in inventory - Change in accounts payable - Change in dividends payable

= $900 + (-$700) + $1,100 + $2,000

= $2,300

Net cash flow from operating activities:

= Net income + Change in operating assets and liabilities

= $98,500 + $2,300

Triangle 1 103, 32 Triangle 2 103,25 are these Triangle similar

Answers

Triangle 1 and Triangle 2 are not similar triangles.

To determine if two triangles are similar, we need to compare their corresponding sides and angles. In this case, we have Triangle 1 with vertices (10, 3) and (32, 10), and Triangle 2 with vertices (10, 3) and (25, 10). Let's compare the corresponding sides and angles:

1. Side lengths:

The length of side AB in Triangle 1 is [tex]√[(32 - 10)^2 + (10 - 3)^2] = √[22^2 + 7^2] = √(484 + 49) = √533.[/tex]

The length of side AB in Triangle 2 is [tex]√[(25 - 10)^2 + (10 - 3)^2] = √[15^2 + 7^2] = √(225 + 49) = √274.[/tex]

2. Angle measurements:

To compare the angle measurements, we need to find the slopes of the sides of the triangles.

The slope of side AB in Triangle 1 is (10 - 3)/(32 - 10) = 7/22.

The slope of side AB in Triangle 2 is (10 - 3)/(25 - 10) = 7/15.

Based on the side lengths and angle measurements, we can see that the side lengths are different and the slopes of the sides are different. Therefore, Triangle 1 and Triangle 2 are not similar triangles.

Similar triangles have corresponding sides that are proportional in length and corresponding angles that are congruent. In this case, the side lengths and angles of Triangle 1 and Triangle 2 are not proportional or congruent, indicating that the triangles are not similar.

Find three points that solve the equation and plot it on a graph -3x + 2y = 11

Answers

The x-axis represents the values of x, and the y-axis represents the values of y. The first point (0, 11/2) lies on the y-axis, at a height of 11/2. The second point (2, 17/2) lies to the right of the y-axis, at a height of 17/2. The third point (-3, 1) lies to the left of the y-axis, at a height of 1.

To find three points that satisfy the equation -3x + 2y = 11, we can arbitrarily assign values to either x or y and solve for the other variable. Let's choose to assign values to x and solve for y:

Let x = 0:

-3(0) + 2y = 11

2y = 11

y = 11/2

The first point is (0, 11/2).

Let x = 2:

-3(2) + 2y = 11

-6 + 2y = 11

2y = 11 + 6

2y = 17

y = 17/2

The second point is (2, 17/2).

Let x = -3:

-3(-3) + 2y = 11

9 + 2y = 11

2y = 11 - 9

2y = 2

y = 1

The third point is (-3, 1).

Now let's plot these points on a graph:

The x-axis represents the values of x, and the y-axis represents the values of y. The first point (0, 11/2) lies on the y-axis, at a height of 11/2. The second point (2, 17/2) lies to the right of the y-axis, at a height of 17/2. The third point (-3, 1) lies to the left of the y-axis, at a height of 1.

By plotting these three points on the graph, you will have a visual representation of the solutions to the equation -3x + 2y = 11.

**Scenario 1: All of his income is salary from his employer. Assume his modified AGI is $520,000.**

Henrich's income tax liability is $133,476.25. This is calculated by first finding his tax bracket, which is the 24% bracket. Then, he multiplies his taxable income by the tax rate for that bracket, which is 24%. This gives him an income tax liability of $112,280.00. He also has a net investment income tax liability of $21,196.25. This is calculated by first finding his net investment income, which is $40,000. Then, he multiplies his net investment income by the net investment income tax rate, which is 3.8%. This gives him a net investment income tax liability of $1,520.00.

**Scenario 2: His $484,500 of taxable income includes $2,000 of long-term capital gain that is taxed at preferential rates. Assume his modified AGI is $520,000.**

Henrich's income tax liability is $133,476.25. This is calculated in the same way as in Scenario 1. His net investment income tax liability is $0. This is because his net investment income is only $2,000, which is below the threshold for the net investment income tax.

**Scenario 3: His $484,500 of taxable income includes $48,000 of long-term capital gain that is taxed at preferential rates. Assume his modified AGI is $520,000.**

Henrich's income tax liability is $133,476.25. This is calculated in the same way as in Scenario 1. His net investment income tax liability is $1,344.00. This is calculated by first finding his net investment income, which is $48,000. Then, he subtracts the preferential rate amount, which is $2,000. This gives him a net investment income of $46,000. Then, he multiplies his net investment income by the net investment income tax rate, which is 3.8%. This gives him a net investment income tax liability of $1,728.00.

**Scenario 4: Henrich has $197,250 of taxable income, which includes $50,900 of long-term capital gain that is taxed at preferential rates. Assume his modified AGI is $214,500.**

Henrich's income tax liability is $54,175.00. This is calculated by first finding his tax bracket, which is the 22% bracket. Then, he multiplies his taxable income by the tax rate for that bracket, which is 22%. This gives him an income tax liability of $43,395.00. He also has a net investment income tax liability of $745.00. This is calculated in the same way as in Scenario 3.

A person observes the top of a radio antenna at an angle of elevation of 5 degrees after getting 1 mile closer to the antenna the angle of elevation is 10 degrees how tall is the antenna to the nearest tenth of a foot?

Answers

The height of the antenna is approximately 5.1 feet.

1. Let's assume the height of the antenna as 'h' feet.

2. We have two angles of elevation: 5 degrees and 10 degrees.

3. When the person is 1 mile closer to the antenna, the change in the angle of elevation is 10 - 5 = 5 degrees.

4. We can use the tangent function to find the height of the antenna. The tangent of an angle is equal to the opposite side divided by the adjacent side.

5. The opposite side is the change in height, which is h feet (since the person moved closer by 1 mile, the change in height is equal to the height of the antenna).

6. The adjacent side is the horizontal distance from the person to the antenna. We can use trigonometry to find this distance.

7. In a right triangle, the tangent of an angle is equal to the ratio of the opposite side to the adjacent side.

  tan(5 degrees) = h / x (where x is the horizontal distance in miles)

8. Similarly, after moving closer, the tangent of the angle becomes:

  tan(10 degrees) = h / (x - 1)

9. We can solve these two equations simultaneously to find the value of h.

10. Rearranging the equations, we get:

  h = x * tan(5 degrees)

  h = (x - 1) * tan(10 degrees)

11. Setting the two expressions for h equal to each other, we have:

  x * tan(5 degrees) = (x - 1) * tan(10 degrees)

12. Solving this equation for x, we find:

  x = tan(10 degrees) / (tan(10 degrees) - tan(5 degrees))

13. Substitute the value of x back into one of the earlier equations to find h:

  h = x * tan(5 degrees)

14. Calculate the value of h using a calculator:

  h ≈ 1 * tan(5 degrees) ≈ 0.0875 miles ≈ 0.0875 * 5280 feet ≈ 461.4 feet

15. Rounded to the nearest tenth of a foot, the height of the antenna is approximately 5.1 feet.

lion plays trumpet for a minmium of 45 mins on the days that he practices. if x is the number of days that lionel practices and y is the total number of hours he spends practicing, which inequality represents this situation

Answers

The inequality representing the situation is "y ≥ 0.75x," where y is the total number of hours Lionel spends practicing and x is the number of days he practices.

To represent the situation where Lionel practices for a minimum of 45 minutes on the days he practices, we can use the variables x and y, where x represents the number of days Lionel practices and y represents the total number of hours he spends practicing.

We know that Lionel practices for a minimum of 45 minutes on each day. Since there are 60 minutes in an hour, this is equivalent to 0.75 hours. Therefore, for each day Lionel practices, he spends at least 0.75 hours.

To find the total number of hours Lionel spends practicing (y), we can multiply the number of days he practices (x) by the minimum number of hours he spends on each day (0.75). This gives us the equation:

y ≥ 0.75x

This inequality states that the total number of hours Lionel spends practicing (y) must be greater than or equal to 0.75 times the number of days he practices (x). It ensures that Lionel practices for a minimum of 45 minutes (0.75 hours) on each day he practices.

By using this inequality, we can track Lionel's practice time and ensure that he meets the minimum requirement of 45 minutes per day.

v2=v02+2ax ; solve for x.

Answers

To solve for x in the equation v2 = v0^2 + 2ax, we can rearrange the equation to isolate x:

x = (v2 - v0^2) / (2a)

In this equation, v2 represents the final velocity, v0 is the initial velocity, a is the acceleration, and x is the displacement. By substituting the given values of v2, v0, and a into the equation, we can calculate the value of x.

The equation v2 = v0^2 + 2ax is derived from the kinematic equation that relates displacement, velocity, acceleration, and time. By isolating x, we can determine the displacement.

The equation represents the final velocity (v2) as the sum of the square of the initial velocity (v0^2) and the product of twice the acceleration (2a) and displacement (x).

To solve for x, we subtract v0^2 from v2 to obtain (v2 - v0^2), and then divide this difference by 2a. This yields the value of x, which represents the displacement.

By substituting the provided values of v2, v0, and a, we can evaluate the expression and calculate the value of x. This equation is commonly used in physics and mechanics to determine the displacement of an object given its initial and final velocities and acceleration.

The definition states that for a given epsilon (ε) greater than zero, there exists a delta (δ) greater than zero such that if the distance between x and the limit point (2, in this case) is less than delta (|x - 2| < δ), then the distance between the function (√x + 7) and the limit (3) is less than epsilon (|√x + 7 - 3| < ε).

Let's solve the inequality |√x + 7 - 3| < ε:

|√x + 7 - 3| < ε

|√x + 4| < ε

-ε < √x + 4 < ε

To remove the square root, we square both sides:

(-ε)^2 < (√x + 4)^2 < ε^2

ε^2 > x + 4 > -ε^2

Since we're interested in the interval around x = 2, we substitute x = 2 into the inequality:

ε^2 > 2 + 4 > -ε^2

ε^2 > 6 > -ε^2

Since ε > 0, we can drop the negative term and solve for ε:

ε^2 > 6

ε > √6

Please note that this solution assumes the function √x + 7 approaches the limit 3 as x approaches 2. To verify the solution, you can substitute different values of δ and check if the conditions of the epsilon-delta definition are satisfied.

y= -x^2 + x+ 12 in intercept form

Answers

Answer:

y = x + 12

Step-by-step explanation:

y = -x² + x + 12

y intercept form is, y = mx + c

where m = -b / a

the general quadratic equation is,

y = ax² + bx + c

thus, according to the question

m = -1 / -1 = 1

constant, c = 12

thus, the intercept form of the equation would be,

Lucas is selling protein bars for a fundraiser. He sold 12 bars on Saturday and 8 bars on Sunday. If each bar sold for $1.50, how much money did he raise?

Answers

The money raised by Lucas for the fundraiser is $30.

The bars sold on Saturday are 12 bars. Each bar costs $1.50.

So, the amount will be:  12 * 1.50 = 18

The bars sold on Sunday are  8 bars.

So, the amount will be:  8 * 1.50 = 12

Hence, the total amount: is 18+12= 30

Answers

The statement that is true about the function is "The function is negative for all real values of x where x < -2."

To determine the statement that is true about the function f(x) = (x + 2)(x + 6) based on the given graph, we can analyze the behavior of the graph and identify the regions where the function is positive or negative.

Looking at the graph:

The function intersects the x-axis at x = -6 and x = -2.

The graph is below the x-axis between x = -6 and x = -2, and above the x-axis outside of that interval.

From this information, we can conclude that the function is negative for all real values of x where x < -2. This is because the graph is below the x-axis in that region.

Therefore, the statement that is true about the function is:

"The function is negative for all real values of x where x < -2."

A spinner is divided into five colored sections that are not of equal size: red, blue, green, yellow, and purple. The spinner is spun several times, and the results are recorded below. Based on these results, express the probability that the next spin will land on red as a percent to the nearest whole number.

Answers

The probability that the next spin will land on red is 7%

How to express the probability that the next spin will land on red?

To express the probability that the next spin will land on red as a percent to the nearest whole number. We need to consider the number of red as proportion of the total.

From the table:

number of red = 4

total = 4 + 18 + 10 + 18 + 11 = 61

Probability that the next spin will land on red = 4/61

As percent to the nearest whole number:

Probability that the next spin will land on red = (4/61) * 100

Probability that the next spin will land on red = 7%

As part of its marketing efforts, it has contracts with several major cities across America, where Lovecraft can place Chthulu scooters in urban centers and allow pedestrians to ride them on their way to whatever destination they intend to go to. Each scooter connects to a phone app where the user can pay for the use of the scooter for a certain amount of time. The app tracks the scooter, but unless the scooter travels far outside a certain area, Lovecraft does not really care where the scooter ends up at the end of the day. It assumes someone else will take the Chthulu out for another ride. One day, young Herbert West was out with his parents when he asked them if he could ride on one of the Chthulus they came across on a street corner. Though Lovecraft had placed a sticker under the seat that said "NO ONE UNDER 18 ALLOWED TO RIDE," Herbert's parents didn't see the harm and, anyway, Herbert was 16 and had his drivers' license. After about an hour, Herbert tired of the scooter and instead of leaving it in one of the marked drop zones around the area, he left it in the street next to the curb. On the signs for the drop zones, there is a notice that says "Municipal Traffic Code 457.6 requires Chthulu scooters to be left in an appropriately marked drop zone." A few years before, Lovecraft had an engineer research a requirement that the scooter would set off an alarm and trigger a series of escalating fines if left outside a drop zone, but the idea was swiftly rejected because (1) the technology would be very expensive and (2) Lovecraft (and the City, which takes 15% of all revenue raised from Chthulu usage) were concerned that such a rule would depress usage, and therefore revenues. Instead, Lovecraft decided to paint all of its public scooters bright colors, and incorporated those colors into its general marketing scheme of being a fun and positive brand. The scooter didn't move for three days, until Erica and her parents came by. They were coming from an audience with the Queen of England, and they were excitedly discussing the event when Erica's father stumbled over the Chthulu scooter Herbert had left behind. The resulting fall caused a concussion and a broken nose. It also prevented him from appearing on Royalty This Week, which airs on several streaming platforms and would have resulted in a 37% increase in sales of his traffic engineering textbooks. Erica is a lawyer, and she is mad that her family has been ensnared by these tentacles of negligence. She helps file a lawsuit, but quickly finds that since the accident, young Herbert West and his family have fallen on hard times, and even if they were responsible, would not have enough money to pay the judgment. But she realizes that Lovecraft has deep pockets, including several tracts of in-state real estate in the city of Arkham. She also realizes that the City is responsible for the Chthulu being there in the first place. So she calls you, her assistant, to ask for ideas about potential causes of action. What ideas do you have for her? Is there anyway to hold Lovecraft liable for the injury to Erica's father? If so, what would be the damages?
