What is the circumference of the circle defined by x^2+6x +y^2-12y-4=0.

Answer:

the answer I believe is c

Step-by-step explanation:

Answer:

b-? is the correct answer

explanation:

The fastest way to find the missing endpoint is to determine the distance from the known endpoint to the midpoint and then performing the same transformation on the midpoint.  In this case, the x-coordinate moves from 4 to 2, or down by 2, so the new x-coordinate must be 2-2 = 0.  The y-coordinate moves from 4 to -5, or down by 9, so the new y-coordinate must be -5-9 = -14.

An alternate solution would be to substitute (4,4) for (x1,y1) and (2,-5) for (x,y) into the midpoint formula:

x=(x1+x2)/2

y=(y1+y2)/2

Solving each equation for (x2,y2) yields the solution (0,-14).

Answer:

b = 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x + y - 8 = 0 ( subtract 3x - 8 from both sides )

y = - 3x + 8 ← in slope- intercept form

with slope m = - 3

Given a line with slope m then the slope of a line perpendicular to it is

\(m_{perpendicular}\) = - \(\frac{1}{m}\) = - \(\frac{1}{-3}\) = \(\frac{1}{3}\)

Consider the second line with equation

- 2x + by + 9 = 0 ← rearrange into slop- intercept form

by = 2x - 9 ( divide terms by b ( b ≠ 0 )

y = \(\frac{2}{b}\) x - \(\frac{9}{b}\) ← in slope- intercept form

with slope m = \(\frac{2}{b}\)

Then

\(\frac{2}{b}\) = \(\frac{1}{3}\) ( cross- multiply )

b = 6

Answer:

u = -3

Step-by-step explanation:

-9 - 4u = -u

    +4  = +4

Add 4u to both sides.

-9 = 3u

Divide both sides by 3

-9/3 = 3/3

-3 = u

Answer: The variable u  is equal to -3 for this equation.

Step-by-step explanation:

To solve this variable equation, you will need to follow these steps:

Rewrite the equation, moving 9 to the other side, adding it on both sides, and simplify

-4u = -u + 9

After that, move u to the other side of the equation, also adding it on both sides and simplify

-3u = 9

Then divide both sides by -3, simplify it one last time and you will get your answer!

-3

Therefore, the answer to this equation would be equal to negative three or -3. Hope this helps!

The probability of rolling a sum of 10 with two dice is 1/12.

Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.

Given that two dice are rolled and find the probability of a sum of 10.

The sample space of the event of rolling two dice is

S = {(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6),

      (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6),

      (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6),

      (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6),

      (5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6),

      (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)}

The total possible outcomes is 36.

The favorable outcomes that is the outcomes where the sum is 10 is

(1, 4), (2, 3), (3, 2).

The number of favorable outcomes are 3.

To find the probability of rolling a sum of 10 with two dice, write the sample space and then determine the number of favorable outcomes that is the outcomes where the sum is 10 and the total number of possible outcomes.

The formula to find out the probability of any event is:

\(\text{P(event)} = \dfrac{(\text{number of favorable outcomes})}{\text{total number of possible outcomes}}\)

By using the data and formula, the probability of rolling a sum of 10 is,

\(\text{P(event)} = \dfrac{(\text{number of favorable outcomes})}{\text{total number of possible outcomes}}\)

\(\text{P(rolling a sum of 10)} = \dfrac{3}{36}\)

On dividing both numerator and denominator by 3 gives,

\(\text{P(rolling a sum of 10)} = \dfrac{1}{12}\)

Hence, the required probability of rolling a sum of 10 with two dice is 1/12.

The probability that you would roll a sum of 10 if you rolled two dice is 1/12.

We need to consider all the possible outcomes and count the favorable outcomes to determine the probability of rolling a sum of 10 when rolling two dice.

When rolling two dice, each die has six possible outcomes, ranging from 1 to 6. To find the total number of outcomes, we multiply the number of outcomes for each die: 6 * 6 = 36.

Next, we need to count the number of favorable outcomes, which are the combinations of two dice that result in a sum of 10. These combinations include:

1. Rolling a 4 on the first die and a 6 on the second die: (4, 6)

2. Rolling a 5 on the first die and a 5 on the second die: (5, 5)

3. Rolling a 6 on the first die and a 4 on the second die: (6, 4)

There are three favorable outcomes.

Therefore, the probability of rolling a sum of 10 when rolling two dice is:

Probability = (Number of favorable outcomes) / (Number of total outcomes) = 3/36 = 1/12.

Hence, the probability is 1/12.

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

The correct equation is −8(r + 14.5) = 64.5

Step-by-step explanation:

This equation states that negative 8 times the sum of a number (r) and 14.5 is equal to 64.5.

The other equations are not correct because they do not correctly represent the given statement. In equation 1, the minus sign is in the wrong place, and in equation 3, the minus sign is missing before the 14.5. In equation 4, the minus sign is missing before the 8.

Step-by-step explanation:

The are ascending

Part A: To calculate the measures of center, we can find the median and the mean for each school.

For Bay Side School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 25, so the median class size is 25.

To find the mean class size for Bay Side School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 12 + 12 + 12 + 14 + 15 + 15 + 16 + 16 + 18 + 18 + 20 + 20 + 23 + 25 + 25 = 243. There are 15 classes, so the mean class size is 243/15 ≈ 16.2.

For Seaside School, the median class size is the average of the 8th and 9th values when the data is sorted in ascending order. The 8th and 9th values are both 15, so the median class size is 15.

To find the mean class size for Seaside School, we can add up all the class sizes and divide by the total number of classes. The sum of the class sizes is 10 + 10 + 10 + 11 + 12 + 15 + 15 + 16 + 17 + 17Part A (continued):

18 + 18 + 20 + 20 + 25 = 222. There are 14 classes, so the mean class size is 222/14 ≈ 15.9.

Therefore, the measures of center for Bay Side School are: median = 25, mean ≈ 16.2.

The measures of center for Seaside School are: median = 15, mean ≈ 15.9.

Part B: To calculate the measures of variability, we can find the range and the interquartile range (IQR) for each school.

For Bay Side School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 12, so the range is 25 - 12 = 13.

To find the IQR for Bay Side School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 15 and Q3 is 20. Therefore, the IQR is 20 - 15 = 5.

For Seaside School, the range is the difference between the largest and smallest class sizes. The largest class size is 25, and the smallest class size is 10, so the range is 25 - 10 = 15.

To find the IQRPart B (continued): for Seaside School, we need to find the first quartile (Q1) and the third quartile (Q3) of the data. From the stem-and-leaf plot, we can see that Q1 is 12 and Q3 is 18. Therefore, the IQR is 18 - 12 = 6.

Therefore, the measures of variability for Bay Side School are: range = 13, IQR = 5.

The measures of variability for Seaside School are: range = 15, IQR = 6.

Part C: If you are interested in a smaller class size, Seaside School is a better choice because its measures of center are lower than those of Bay Side School, indicating that its class sizes tend to be smaller on average. Additionally, Seaside School has a smaller range and IQR, indicating less variability in class size. Therefore, there is less chance of encountering very large classes at Seaside School compared to Bay Side School.

Answer:

Part A: the second choice

Part B: 72 blocks

Step-by-step explanation:

The prism has 3 layers and 24 blocks per layer. The base of each layer of the second choice has a width of 8 and length of 3.

8*3=24.

Multiply the 24 blocks on each layer with the 3 layers and we get 72 blocks in total.

We can check this by multiplying the dimensions of the prism together. 3*3*8=72 and this verifies that we are correct.

\(\frac{1}{w^{6} }\) i hope this helps!!

Answer:

The simplified expression is 1/w^6.

Step-by-step explanation:

Using the product of powers exponent rule, we have

w^3 * w^(-9) = w^(3 + (-9)) = w^(-6).

However, the problem says to write the expression using only positive exponents. Here's an example of how to interpret negative exponents as positive exponents:

3^2 = 9

3^1 = 3

3^0 = 1

3^(-1) = 1/3

(and keeps on dividing by three onward)

Here, we see that 3^(-1) = 1/3^1.

Applying the same logic here, we have

w^(-6) = 1/w^6.

Answer:

Area of the sector = \(24\pi ^{2}\)

The perimeter of the sector of the given circle is 32.75 cm.

The perimeter of a sector is given by the sum of the arc length and the two radii that form the sector. To find the perimeter of this sector, we need to find the length of the arc and the two radii.

The area of the sector is given as 120° at the center. We can use this information to find the length of the arc by using the formula for the area of a sector:

                          Area of sector = (angle/360) x πr²

where r is the radius of the circle and angle is the central angle of the sector in degrees.

In this case, we have:

                          120/360 x π x 8² = 33.51 cm² (rounded to two decimal places)

The length of the arc can be found by using the formula:

                          Arc length = (angle/360) x 2πr

In this case, we have:

                          (120/360) x 2π x 8 = 16.75 cm (rounded to two decimal places)

The two radii that form the sector have lengths of 8 cm each.

Therefore, the perimeter of the sector is the sum of the arc length and the two radii:

                          Perimeter = arc length + 2r

                          = 16.75 + 2(8)

                          = 32.75 cm (rounded to two decimal places)

Therefore, the perimeter of the sector is approximately 32.75 cm.

Answer:

x=127°

Step-by-step explanation:First you have to solve for n and to do so you have to add the interior angles together and equal them to the remote exterior angle.

n+7+6n+22=197-5n

12n+29=197

12n=168

n-14

once you get n you have to plug it into 197-5n

197-5(14)

197-70

127

The required value of exterior angle  m∠x is 127.

From figure x is remote exterior angle m∠x=(197−5n)°. and y and z are interior angles m∠y=(6n+22)° and m∠z=(n+7)° respectively. value of x to be determine.

Angle made at outer side of the corner is called exterior angles.

Here, by properties,  sum of the interior angle = remoter exterior angle
So,
m∠x = m∠y + m∠z
197−5n = 6n+22+n+7
168 = 12n
n = 14
put n in m∠x
m∠x=(197−5n)°
m∠x=(197−5*14)°
m∠x=(197−70)°
m∠x=127°

Thus, the required value of exterior angle  m∠x is 127.
