The question doesn't provide enough information to answer it properly, as it doesn't specify the polynomial or the divisor necessary for synthetic division. Synthetic division involves dividing a polynomial by a linear divisor, but without the set polynomial and divisor, the number that would belong in the place of the question mark can't be determined.
Explanation:Unfortunately, the information provided doesn't clearly indicate the format or context of a synthetic division problem. Synthetic division typically involves dividing a polynomial by a linear divisor. The elements of the polynomials are numbers, specifically the coefficients of the polynomial terms. The repetition in your question about various Car X, Car Y and dots at various hash marks appears to be irrelevant data as it does not correlate with the synthetic division problem.
However, to apply synthetic division, we would need a specific polynomial to carry out the process. In synthetic division, a box is drawn, the coefficients of the polynomial are written in that box, and then the divisor is placed outside the box. From there, the numbers inside the box are manipulated, in a step-by-step manner, based on the divisor. The numbers derived from this process are the coefficients of the answer. Without this specific data, we cannot accurately determine what number belongs in the place of the question mark.

The Venn diagram shows the results of two events resulting from rolling a number cube.
Events C and D are____.
P(C) = 1/3
P(D) = 1/3
P(C ∩ D) = 0
P(C | D) ≠ 0
This is geometry, dealing with conditional probability.
Answers
Answer:
Events C and D are mutually exclusive.
P(C ∩ D) = 0
Step-by-step explanation:
We notice that event C is even numbers and Event D is odd number. We cannot roll a die and have both events occur at the same time. That means they are mutually exclusive. Either one event occurs or the other occurs.
P(C ∩ D) = 0 This means the events do not intersect (overlap). Or are mutually exclusive.

Step-by-step explanation:
We have been given a graph which shows number of revolutions v/s distance traveled in feet.
Answer (a):
Now we need to find about how far does Miguel travel per revolution. That means find distance traveled in 1 revolution.
From graph we see that 10 revolution corresponds to 15 feet.
then 1 revolution = 15/10 = 1.5 feet
hence final answer is 1.5 feet.

-- The incenter of a triangle is the point where the angle bisectors meet.
Answers
Answer:
Step-by-step explanation:
Given are some properties of triangles and we have to check whether they are correct
i) Only two of three angle bisectors of the internal angles of a triangle are concurrent.
This is incorrect since all three angle bisectors concur at incentre
ii) The circumcenter of a triangle is the point where the perpendicular bisectors of the sides meet.
-- correct because the meeting point is equidistant from all three vertices
iii) Given any three non-collinear points, there exists exactly one circle that passes through the points.
-- correct because any three points determine a circle
iv) Given any three non-collinear points, there exists exactly one circle that passes through the points.
-- Correct
v) The incenter of a triangle is the point where the angle bisectors meet.
-- Correct and the centre is equidistant from the sides of the triangle
Statements 2, 3, and 5 are correct.
Analyze each statement to determine which are correct:
Only two of three angle bisectors of the internal angles of a triangle are concurrent. This statement is incorrect. All three angle bisectors of the internal angles of a triangle are concurrent and meet at a single point called the incenter.The circumcenter of a triangle is the point where the perpendicular bisectors of the sides meet. This statement is correct. The perpendicular bisectors of the sides of a triangle meet at a point called the circumcenter, which is the center of the circle that passes through all three vertices of the triangle (circumscribed circle).Given any three non-collinear points, there exists exactly one circle that passes through the points. This statement is correct. For any three non-collinear points, there is exactly one unique circle that can pass through all three points. This is the circumscribed circle of the triangle formed by the points.A circumscribed circle is the circle that passes through all three vertices of a triangle and it is the smallest triangle contained within any triangle. This statement is incorrect. While a circumscribed circle does pass through all three vertices of a triangle, it does not describe any triangle, let alone the smallest one contained within another triangle.The incenter of a triangle is the point where the angle bisectors meet. This statement is correct. The incenter, where the angle bisectors meet, is the center of the inscribed circle that fits inside the triangle.In a certain region, the equation yˆ=19.485x+86.912 models the amount of a homeowner’s water bill, in dollars, where x is the number of residents in the home.

State the domain and range for the function
Answers
Answer:
* Domain: all reals except multiples of 2π
* Range: (-∞ , -2] ∪ [2 , ∞)
Step-by-step explanation:
* Lets revise the period, the domain and the range of csc(x)
- The period of csc(x) is 2π
- To find the period of csc(x) use 2π / coefficient of x
- The domain of csc(x) is all x ≠ nπ
- The range is y ≤ -1 , y ≥ 1
* Lets revise the vertical and the horizontal stretch and compress
- A vertical stretching is the stretching of the graph away from
the x-axis
• if k > 1, the graph of y = k•f(x) is the graph of f(x) vertically
stretched by multiplying each of its y-coordinates by k.
- A vertical compression is the squeezing of the graph toward
the x-axis.
• if 0 < k < 1 (a fraction), the graph is f (x) vertically compressed
by multiplying each of its y-coordinates by k.
- A horizontal stretching is the stretching of the graph away from
the y-axis
• if 0 < k < 1 (a fraction), the graph is f (x) horizontally stretched by
dividing each of its x-coordinates by k.
- A horizontal compression is the squeezing of the graph toward
the y-axis.
• if k > 1, the graph of y = f (k•x) is the graph of f (x) horizontally
compressed by dividing each of its x-coordinates by k
∵ f(x) = 2csc(x/2)
- The coefficient of x is 1/2
∵ The period of x = 2π
∴ The period of x/2 = 2π/1/2 = 4π
∵ The domain of csc(x) is all x ≠ nπ
∴ The domain of csc(x/2) is all x ≠ n2π
∵ f(x) = 2csc(x/2)
∵ csc(x/2) multiplying by 2
- That means every y-coefficient multiplying by 2
∵ The range of csc(x/2) is y ≤ -1 and y ≥ 1
∴ The rang of f(x) = 2csc(x/2) is y ≤ -1(2) and y ≥ 1(2)
∴ The rang of f(x) = 2csc(x/2) is y ≤ -2 and y ≥ 2
* Domain: all reals except multiples of 2π
* Range: (-∞ , -2] ∪ [2 , ∞)
* Look to the graph attached
- The red is y = csc(x)
- The blue is f(x) = 2csc(x/2)

Step-by-step explanation:
Answer:
V = 392.7 m3
Step-by-step explanation:
To find the volume of the cone, first calculate the hieght and the radius.
To find the length of the radius, equate the given area to the formula for the area of a circle and solve for r.
πr2=25π
Divide both sides by π.
r2=25
Take the positive square root of both sides.
r=5 m
It is given that the height of the cone equal to three times the radius. So, use the radius to find the height.
h=3r
Substitute 5 for r.
h=3⋅5
Simplify.
h=15 m
To find the volume of the cone, use the formula for the volume of a cone.
V=13πr2h
Substitute 5 for r and 15 for h.
V=13⋅π⋅52⋅15
Simplify.
V=125π
Use a calculator to approximate.
V≈392.7 m3
Therefore, the volume of the cone is about 392.7 m3.

Final answer:
To determine how much fish the walruses are fed, multiply the 2 1/3 buckets of fish fed to dolphins by 5. The calculation gives us an answer of 11 2/3 buckets of fish fed to walruses each day.
Explanation:
The dolphins at the sea aquarium are fed 2 1/3 buckets of fish each day. To find out how much the walruses are fed, we have to multiply the quantity of fish fed to dolphins by 5, since walruses are fed 5 times as much.
First, convert 2 1/3 to an improper fraction: 2 1/3 = 7/3.
Now, multiply 7/3 by 5 to get the walruses' daily fish intake in buckets.
7/3 × 5 = 35/3.
35/3 is an improper fraction, and when converted to a mixed number, it equals 11 2/3 buckets of fish per day.
Hence, the walruses at the sea aquarium are fed 11 2/3 buckets of fish each day.

Based on the diagram the cross section of the solid contains a six sided plane figure known as a hexagon.
An hexagon is a polygon with six equal sides and angles.
what are the steps to solving this equation?
35 + 3x – 11 = 23
Answers
The first step is to combine like terms, 35 and 11 are both integers without variables, so we can combine.
24+3x= 23
Now we subtract 24 from 23 to isolate 3x, and we get -1.
3x=-1
To solve we just need to divide -1 by 3.
Answer: -1/3
The value of x after solving the equation will be equal to -1/3

How do you use special right triangles to solve for missing sides? (30-60-90 and 45-45-90 triangles)
Answers
Answer: see below
Step-by-step explanation:
30 - 60 - 90 triangles have angles in the triangle measuring 30, 60, and 90 degrees. A 30 - 60 - 90 triangle also has special side ratios according to a side's location in the triangle.
The side across from the 30 degree angle is represented by x.
The side across from the 60 degree angle is represented by x[tex]\sqrt{3}[/tex].
The side across from the 90 degree angle is represented by 2x.
45 - 45 - 90 triangles have angles in the triangle measuring 45, 45, and 90 degrees. A 45 - 45 - 90 triangle has special side ratios similar to the 30 - 60 - 90 triangle.
The side across from either of the 45 degree angles is represented by x.
The side across from the 90 degree angle is represented by x[tex]\sqrt{2}[/tex].
These ratios can be used to find missing sides. If you know that a triangle is one of these special triangles and you also know one of its side lengths, you can plug the known length in for x in the proper place.
EX: you have a 30 - 60 - 90 triangle with a side length of 2 across from the 30 degree angle. You then know that the side across from 60 is 2[tex]\sqrt{3}[/tex] and the side across from 90 is 4.

Let point Q = (4,y)
√[ (4-0)^2 + (y-0)^2 ] = √[ (6-0)^2 + (0-0)^2 ]
Square both side
(4-0)^2 + (y-0)^2 = (6-0)^2 + (0-0)^2
4^2 + y^2 = 6^2
16 + y^2 = 36
y^2 = 36-16
y^2 = 20
y= √20
y= 2√5
Answer:
2√5
Step-by-step explanation:
On the graphic, you see point Q is roughly between 4 and 4.5 units on the Y-axis.
So, all we have to do is find a value similar to that in the answer choices. So, let's look at the values:
2√5: 2 * 2.23 = 4.46... that's pretty much what we're looking for.
4√2: 4 * 1.41 = 6.4. Way too big.
2√13: 2 * 3.6 = 7.2, way too big.
8√2: We know that will necessary be way bigger than 4.5, so let's not even evaluate it.

Answers
Answer:
10 cm
Step-by-step explanation:
Answer:
10 cm
Step-by-step explanation:
Since, the volume of a cuboid is,
V = l × w × h,
Where,
l = length,
w = width,
h = height,
∵ The shape of the aquarium must be cuboid,
We have, l = 20 cm, w = 12 cm, V = 2400 cm³,
By substituting the values,
2400 = 20 × 12 × h
2400 = 240h
[tex]\implies h = \frac{2400}{240}=10[/tex]
Hence, the height of the water in Nemo's aquarium would be 10 cm.
