Step-by-step explanation:

The estimated median price of a single-family home in Charleston/No. Charleston in the 1st Quarter of 2008 is $201,048. If the median price continues to decrease at the same rate for the next two years, the estimated median price of a single-family home in the 1st Quarter of 2011 would be $144,458.

(a) To estimate the median price of a single-family home in the 1st Quarter of 2008, we need to calculate the original price before the 8.15% decrease. Let's assume the original price was P. The price after the decrease can be calculated as P - 8.15% of P, which translates to P - (0.0815 * P) = P(1 - 0.0815). Given that the end of 1st Quarter of 2009 median price was $184,990, we can set up the equation as $184,990 = P(1 - 0.0815) and solve for P. This gives us P ≈ $201,048 as the estimated median price of a single-family home in the 1st Quarter of 2008.

(b) If the median price of a single-family home falls at the same rate for the next two years, we can calculate the price for the 1st Quarter of 2011 using the estimated median price from the 1st Quarter of 2009. Starting with the median price of $184,990, we need to apply an 8.15% decrease for two consecutive years. After the first year, the price would be $184,990 - (0.0815 * $184,990) = $169,805.95. Applying the same percentage decrease for the second year, the price would be $169,805.95 - (0.0815 * $169,805.95) = $156,012.32. Therefore, the estimated median price of a single-family home in the 1st Quarter of 2011 would be approximately $144,458.

Step-by-step explanation:

Given:

  3x +2y = 5

Find:

  a) two points that satisfy the equation

  b) slope and y-intercept

  c) x-intercept

Solution:

Since the intercepts are points on the line, finding them satisfies all parts of the question except finding the slope.

a) Let x=0. Then we can find y from ...

  3·0 +2y = 5

  y = 5/2

One point is (0, 5/2).

Let y=0. Then we can find x from ...

  3x +2·0 = 5

  x = 5/3

Another point is (5/3, 0).

Two points on the line are (0, 5/2) and (5/3, 0).

__

b) The slope can be found using the slope formula on the two points we found.

  m = (y2 -y1)/(x2 -x1)

  m = (0 -5/2)/(5/3 -0) = -(5/2)/(5/3) = -3/2

The slope is -3/2. The y-intercept is 5/2.

__

c) The x- and y-intercepts are (5/3, 0) and (0, 5/2), respectively.

Sasha should use 2 desired outcomes in her probability calculation to determine that she has a 1/3 chance of winning the game.

To calculate Sasha's probability of winning, we need to determine how many desired outcomes she has. In this game, Sasha needs to spin a number higher than both of her friends' spins, which means she needs to spin a number greater than 1 and 4.

Let's analyze the spinner pictured. From the image, we can see that the spinner has numbers ranging from 1 to 6. Since Sasha needs to spin a number higher than 4, she has two options: 5 or 6.

Now, let's consider the desired outcomes. Sasha has two desired outcomes, which are spinning a 5 or spinning a 6. If she spins either of these numbers, she will have a number higher than both of her friends and win the game.

To calculate Sasha's probability of winning, we need to divide the number of desired outcomes by the total number of possible outcomes. In this case, the total number of possible outcomes is the number of sections on the spinner, which is 6.

Sasha's probability of winning is 2 desired outcomes divided by 6 total outcomes, which simplifies to 1/3.

Answer:

  (s, f) = (4.5, 2.25)

Step-by-step explanation:

You want the solution to the simultaneous equations ...

Writing these in general form, we have ...

  3s +2f -18 = 0

  2s +3f -15.75 = 0

Using the "cross-multiplication method" for solution, we find ...

  ∆1 = (3)(3) -(2)(2) = 5

  ∆2 = (2)(-15.75) -(3)(-18) = 22.5

  ∆3 = (-18)(2) -(-15.75)(3) = 11.25

  s = ∆2/∆1 = 22.5/5 = 4.5

  f = ∆3/∆1 = 11.25/5 = 2.25

The solution is (s, f) = (4.5, 2.25).

The red angle markers show those two angles are congruent. That's one "A" of "ASA". The S refers to a congruent pair of sides. We don't have any tickmarks to indicate congruent pairs; however, we do know that QR = QR is a shared side that overlaps (reflexive theorem). So this is the "S" in "ASA".

The thing missing is the angle Q of the top triangle, and also of the bottom triangle as well. If we know those two angles are congruent, then we have enough info to use ASA. More specifically, if we know that \(\angle SQR \cong \angle XQR\), then we can use ASA.

One thing to notice is that the other answer choices involve side lengths and not angles. This implies that if A, B or C were one of the answers, then we would have something like SAS or SSS. But instead we want ASA. So we can immediately rule choices A,B, and C out.

According to the text, in a true experimental study, the subjects should be assigned to groups randomly. If this is not possible and a researcher uses intact groups, they are performing a quasi-experimental study.

Quasi-experimental studies are research designs that include some elements of an experimental study but are lacking in the key feature of random assignment to a treatment or control group. Researchers may compare groups that already exist, for example, individuals who already smoke and those who do not. Because the groups are not chosen randomly, researchers cannot attribute differences in results to the effects of the treatment in question.A quasi-experimental study is a type of study in which researchers analyze a natural experiment in which subjects in the study are not randomly assigned to the treatment and control groups. The goal is to compare the outcomes of the treatment and control groups while minimizing the effects of other factors that might interfere with the results.

5x + 4y = 80

Step-by-step explanation:
First, let us look at the given:

x = The number of songs purchased

y = The remaining balance of Renata's gift card

Coordinates:

1. (16,0)

2. (0,20)

Now let's look at the unknown:

Slope =?

Since we have the coordinates we can easily apply the slope formula

Now that we have our slope we can use either point-slope formation or slope-intercept formation, just pick whichever one you're comfortable with.

Point-slope formation

y - y1 = slope (x - x1)

Now just plug in the numbers:

y - 0 = 20/-16 (x - 16)

Now you multiply both sides by -16 to get rid of the fraction

-16(y - 0) = -16 (20/-16) (x - 16)

-16y - 0 = 20 (x - 16)

-16y = 20x - 320

Now subtract 20 from both sides.

-16y - 20x = 20x - 20x - 320

-20x - 16y = -320

Now we need to simplify both sides so we divide both sides by 4

-5x - 4y = -80

Now, remember, one of the rules of standard formation is that the coefficient of x cannot be smaller than zero. So you need to multiply both sides by -1.

-1 (-5x - 4y) = (-80) -1

5x + 4y = 80

To determine which of the given images (A, B, or C) shows the given figure moving down. Looking at the figure, we can see that the movement requires both a vertical and horizontal change. Therefore, we need to find an image that represents a downward and rightward movement.

Image B shows the figure moving down 2 units and right 3 units. We can see that the figure is shifted to the right by three units and down by two units relative to the original position.

Image A shows the figure moving up by two units and rightward by three units, which is the opposite direction to the required movement.

Image C shows the figure moving leftward by three units and up by two units, which is also the opposite direction to the required movement.

In summary, image B shows the given figure moving down 2 units and right 3 units.

To determine which of the images (A, B, or C) shows the given figure moving down 2 units and right 3 units, follow these steps:

1. Identify the original position of the figure in each image.
2. Observe the movement of the figure in each image.
3. Compare the movement of the figure with the required movement (down 2 units and right 3 units).

First, locate the initial position of the figure in each image. Then, observe how the figure has been moved in each of the three images. For each image, check whether the figure has been moved downwards by 2 units and to the right by 3 units.

For example, if the figure in Image A moves down by 2 units and to the right by 3 units, this image would be the correct answer. If the figure in Image B moves down by 1 unit and to the right by 4 units, this image would not be the correct answer. Similarly, if the figure in Image C moves up by 2 units and to the right by 3 units, this image would not be the correct answer either.

Once you have evaluated each image based on the given criteria, you will be able to identify which image (A, B, or C) correctly shows the figure moving down 2 units and right 3 units.

The measure of the smaller interior angle is approximately 144 degrees.

The measure of the larger interior angle is 36 degrees.

Let's denote the measure of the smaller interior angle as x.

According to the given information, the measure of one interior angle (let's call it y) is 0.25 times the measure of the smaller angle. Therefore, we can write the equation:

y = 0.25x

Since a parallelogram has opposite angles congruent, we know that the sum of the measures of the smaller and larger angles is 180 degrees. Hence, we can write another equation:

x + y = 180

Substituting the value of y from the first equation into the second equation, we have:

x + 0.25x = 180

Combining like terms:

1.25x = 180

To find the measure of the smaller angle (x), we divide both sides of the equation by 1.25:

x = 180 / 1.25

x ≈ 144

Therefore, the measure of the smaller interior angle is approximately 144 degrees.

To find the measure of the larger interior angle, we substitute the value of x into the equation:

y = 0.25x

y = 0.25 * 144

y = 36

Hence, the measure of the larger interior angle is 36 degrees.

The rocket will be 10 feet from the ground approximately 9.15 seconds after it is launched, and this can be found by solving the equation -16t^2 + 150t + 60 = 10.

To find out when the rocket will be 10 feet from the ground, we need to find the value of t that makes h equal to 10 feet. Given that the height of the rocket at time t is h = -16t^2 + 150t + 60, we can set this equal to 10 and solve for t:

-16t^2 + 150t + 60 = 10

Simplifying the equation by subtracting 10 from both sides:

-16t^2 + 150t + 50 = 0

Dividing both sides by -2, we get:

8t^2 - 75t - 25 = 0

To solve this quadratic equation, we can use the quadratic formula:

t =\([-b \± \sqrt(b^2 - 4ac)] / 2a\)

where a = 8, b = -75, and c = -25. Substituting these values, we get:

t =\([75 \±\ sqrt(75^2 - 4(8)(-25))] / 2(8)\)

t = \([75 \± \sqrt(7145)] / 16\)

t ≈ 9.15 seconds or t ≈ 0.41 seconds

Since the rocket is launched from the top of a 60-foot cliff, it will be 10 feet above the ground only after it has fallen below the level of the cliff. Therefore, we can ignore the solution t ≈ 0.41 seconds and conclude that the rocket will be 10 feet from the ground approximately 9.15 seconds after it is launched.

vertical asymptotes :

x = 3

B) y = x²/(x² - x - 12)

C) y = 2x²/(x² + x - 12)

D) y = 2x²/(x² - x - 12)

so, for which ones we have y = 2 as limit when x goes against + or - infinity ?

that would be C and D.

A and B lead to x²/x² = 1 as limit for gigantic numbers.

C and D lead to 2x²/x² = 2 as limit.

remember, when x gets really, really big, the "±x - 12" part becomes irrelevant.

so, we look at C and D.

which one lead to a division by 0 at x = 3 and x = -4 ?

that would be C.

for x = 3

x² + x - 12 = 3² + 3 - 12 = 9 + 3 - 12 = 12 - 12 = 0

for x = -4

x² + x - 12 = (-4)² - 4 - 12 = 16 - 4 - 12 = 12 - 12 = 0

D with x² - x - 12 would have x = -3 and x = 4 as zeroes.
