If Jenna’s age is x, the equation that represents the situation is; C. x + 5 = (x + 5) − 5, which has no solution

We are given;

Jessica is 5 years older than her sister Jenna.

If Jenna is x years old, then;

Jessica's current age = x + 5

Jenna tells her sister that in 5 years, she will be as old as Jessica was 5 years ago. Thus;

Jenna's age in 5 years time = (x + 5) - 5

This means that Jenna'a age in 5 years time normally is (x + 5). Thus, we will now have the equation;

x + 5 = (x + 5) − 5, which has no solution

If the target behavior is recorded whenever it occurs at any point within the scoring interval, the measurement procedure used is called continuous recording or event recording. This method involves observing and recording each instance of the behavior without considering its duration or intensity.

Continuous recording is typically used when the target behavior is discrete and occurs relatively infrequently or has a short duration. With this measurement procedure, each occurrence of the behavior is recorded as a separate event, regardless of when it starts or ends within the scoring interval. Examples of behaviors that can be measured using continuous recording include vocalizations, hand clapping, or instances of aggression.

Continuous recording provides a comprehensive account of the frequency or rate at which the behavior occurs, allowing for a detailed analysis of its occurrence patterns. This method is particularly useful when a precise count of behavior instances is needed and when the duration or intensity of the behavior is not a focus of measurement.

The  values of x will f(x) > 0 for x < 0, and f(x) < 0 for -6 < x < 0 and x > -6.

To determine the values of x for which f(x) > 0, we need to find the intervals where the function is positive. Let's analyze the function f(x) = x*-x³-6x².

First, let's factor out an x from the expression to simplify it: f(x) = x(-x² - 6x).

Now, we can observe that if x = 0, the entire expression becomes 0, so f(x) = 0.

Next, we analyze the signs of the factors:

1. For x < 0, both x and (-x² - 6x) are negative, resulting in a positive product. Hence, f(x) > 0 in this range.

2. For -6 < x < 0, x is negative, but (-x² - 6x) is positive, resulting in a negative product. Therefore, f(x) < 0 in this range.

3. For x > -6, both x and (-x² - 6x) are positive, resulting in a negative product. Thus, f(x) < 0 in this range.

The Probability = (number of candidates - 1) * (number of committee members) / (number of candidates ^ number of committee members)

The probability that a candidate will be selected with only one dissenting vote depends on the total number of committee members and the number of candidates.

First, we need to calculate the total number of ways that the committee members can vote. This is equal to the number of candidates raised to the power of the number of committee members. For example, if there are 3 candidates and 5 committee members, the total number of ways that the committee members can vote is 3^5 = 243.

Next, we need to calculate the number of ways that a candidate can be selected with only one dissenting vote. This is equal to the number of candidates minus 1 (for the dissenting vote) multiplied by the number of committee members (for the number of ways that the dissenting vote can be placed).

For example, if there are 3 candidates and 5 committee members, the number of ways that a candidate can be selected with only one dissenting vote is (3-1) * 5 = 10.

Finally, we can calculate the probability by dividing the number of ways that a candidate can be selected with only one dissenting vote by the total number of ways that the committee members can vote. For example, if there are 3 candidates and 5 committee members, the probability is 10/243 = 0.041. In general, the probability that a candidate will be selected with only one dissenting vote is: Probability = (number of candidates - 1) * (number of committee members) / (number of candidates ^ number of committee members)

Nastya's annual payments on the loan will be approximately $7,350.68 (rounded to the nearest cent).

To find Jean's equity as a percent of the house value, we need to calculate the equity and divide it by the house value, then multiply by 100 to get the percentage.

Jean's equity is the difference between the house value and the mortgage amount. So, the equity is $792078.31 - $600,000 = $192,078.31.

To calculate the percentage, we divide the equity by the house value and multiply by 100: ($192,078.31 / $792078.31) * 100 = 24.26%.

Therefore, Jean's equity as a percent of the house value is 24.26%.

Now, let's move on to Nastya's question.

To calculate Nastya's annual payments on a fully amortizing loan, we need to use the formula for calculating the monthly payment:

P = r * PV / (1 - (1 + r)^(-n))

Where:
P = Monthly payment
r = Monthly interest rate (annual interest rate / 12)
PV = Present value of the loan
n = Total number of payments

Given:
PV = $622,422
Annual interest rate = 5.2%
n = 10 years

First, we need to convert the annual interest rate to a monthly interest rate: 5.2% / 12 = 0.43333%.

Next, we substitute the values into the formula and solve for P:

P = (0.0043333 * 622422) / (1 - (1 + 0.0043333)^(-10))

Using a calculator, we get P ≈ $7,350.68.

3x/3 = 66/3

x=11

79-y=2x

79-y=2(11)

79-y=22

79-22=y

y=57

therefore x=11 and y=57

3x-10=56

79-y=2x    so y=-2x+79

(Solve 3x−10=56 for x):

3x−10=56

3x−10+10=56+10 (Add 10 to both sides)

3x=66

Answer:

If you sketch the directrix and the focus, the vertex is halfway between them. It would be (-8,-1)

The p value is the distance from the focus to the vertex and the distance between the vertex and the directrix (they are the same) p=3.

The direction of the focus from the vertex will show which way it opens. The one opens down.

Step-by-step explanation:

hehe

Answer:

Step-by-step explanation:

The vertex of a parabola is halfway between the focus and the directrix. The p-value of the equation is half the distance from the focus to the directrix. The parabola opens around the focus, away from the directrix.

__

That is, the vertex will lie on the same vertical line, but have a y-coordinate that is the average of the y-values of the focus and directrix. Here, that means the y-value of the vertex is ...

  (directrix +focus)/2 = (3 +(-2))/2 = 1

The focus is on the vertical line x=8. The coordinates of the vertex are (8, 1).

__

The parameter "p" is part of the leading coefficient of the quadratic defining the parabola. It fits into the vertex-form equation as shown here:

  \(y=\dfrac{1}{4\mathbf{p}}(x-h)^2+k\qquad\text{vertex at $(h,k)$}\)

The value of p is the distance from the focus to the vertex. When the focus is below the vertex, as here, the value of p will be negative.

  p = (focus y-value) - (vertex y-value) = (-1) -1

  p = -2

__

The focus lies "inside" the parabola, and the directrix lies "outside." The parabola "wraps around" the focus, away from the directrix. When the focus is below the directrix, the parabola opens downward. (The leading coefficient of the equation is negative, telling you the same thing.

_____

Additional comment

The parabola is the set of points equidistant from the focus and directrix. Thus it should come as no surprise that the vertex is equidistant from the focus and directrix. They lie on the same vertical line when the directrix is horizontal.

The latus rectum is the line segment parallel to the directrix, through the focus, with end points on the parabola. Its end points always lie on a line with slope ±1/2 through the vertex. This can help you find (or verify) the focus graphically.

To draw the image of quadrilateral ABCD under a translation by 1 unit to the right and 4 units up, we will move each point of the quadrilateral in the specified direction.

Let's assume the coordinates of the original quadrilateral ABCD are as follows:

A(x₁, y₁), B(x₂, y₂), C(x₃, y₃), D(x₄, y₄)

To perform the translation, we will add the given values to the x-coordinates and y-coordinates of each point:

A'(x₁ + 1, y₁ + 4), B'(x₂ + 1, y₂ + 4), C'(x₃ + 1, y₃ + 4), D'(x₄ + 1, y₄ + 4)

Now, plot the original quadrilateral ABCD and then move each point to its corresponding new position.

For example, if point A had coordinates (2, 3), after the translation, it will move to (2 + 1, 3 + 4) = (3, 7). Similarly, you can calculate the new coordinates for points B, C, and D using the same process.

Once you have the new coordinates for each point, connect them to form the image of the quadrilateral ABCD under the translation.

The new quadrilateral A'B'C'D' will be a shifted version of the original quadrilateral, 1 unit to the right and 4 units up.

It's important to note that the scale and proportions of the quadrilateral will remain the same after the translation. Only its position in the coordinate plane will change.

The given series 9 - 10 + 100/9 - 1000/81 + ... is a geometric series with the first term a = 9 and the common ratio r = -10/9. To check if the series is convergent or divergent, we need to find the absolute value of the common ratio, which is |-10/9| = 10/9 > 1. Since the absolute value of the common ratio is greater than 1, the series is divergent.

Therefore, the series does not have a finite sum. The expression a(-10/9)^2 is not applicable here as the series is not convergent.
In the given geometric series 9 - 10 + 100/9 - 1000/81 + ..., let's first find the common ratio (r). We can do this by dividing a term by its preceding term:

r = (-1000/81) / (100/9) = (-1000/81) * (9/100) = -10/9

Now, let's find the first term (a). We know that the n = 2 term is 100/9, which equals a * r^2:

100/9 = a * (-10/9)^2

Solving for a, we get:

a = (100/9) / (100/81) = 81/9 = 9

Now that we have a = 9 and r = -10/9, we can determine if the series converges or diverges. A geometric series converges if the absolute value of r is less than 1, which is true in this case:

|-10/9| < 1

Since the series converges, we can find its sum using the formula for the sum of an infinite geometric series:

Sum = a / (1 - r) = 9 / (1 - (-10/9)) = 9 / (19/9) = 9 * (9/19) = 81/19

So, the sum of the given geometric series is 81/19.
