The vertex of a parabola (1.75, -0.25). The vertical intercept of a parabola is (0, 11). The two intercepts of the parabola ((7 + √5)/4, 0) and ((7 - √5)/4, 0).
A) The vertex of a parabola is given by the formula (h, k), where h = -b/2a and k = f(h). In this case, a = 4, b = -14, and c = 11. So, h = -(-14)/2(4) = 14/8 = 1.75. Plugging this value back into the equation, we get k = f(1.75) = 4(1.75)^2 - 14(1.75) + 11 = -0.25. Therefore, the vertex of the parabola is (1.75, -0.25).
B) The vertical intercept is the point where the parabola crosses the y-axis, which occurs when x = 0. Plugging this value into the equation, we get f(0) = 4(0)^2 - 14(0) + 11 = 11. Therefore, the vertical intercept is the point (0, 11).
C) The two intercepts of the parabola are the points where it crosses the x-axis, which occur when f(x) = 0. We can use the quadratic formula to find these values:
x = (-b ± √(b^2 - 4ac))/2a
x = (-(-14) ± √((-14)^2 - 4(4)(11)))/2(4)
x = (14 ± √(196 - 176))/8
x = (14 ± √20)/8
x = (14 ± 2√5)/8
x = (7 ± √5)/4
Therefore, the two intercepts are the points ((7 + √5)/4, 0) and ((7 - √5)/4, 0).

Put the function y=10x(x+1) in factored form f(x)=a(x-r)(x-s) and state the values of a,r, and s. (Assume r ≤ x)
The function y=10x(x+1) is already in factored form, with a=10, r=0, and s=-1.
A function in mathematics from a set X to a set Y allocates exactly one element of Y to each element of X. The set X is termed the domain of the function and the set Y is called the codomain of the function. Initially, functions represented the idealized relationship between varied quantities and other variables.
To see this, we can rewrite the function as f(x)=10(x-0)(x-(-1)), which matches the form f(x)=a(x-r)(x-s). Therefore, the values of a, r, and s are:
a = 10
r = 0
s = -1
It is important to note that the values of r and s are the x-intercepts of the function, or the values of x that make the function equal to zero. In this case, the x-intercepts are 0 and -1, which correspond to the values of r and s.

Dijkstra's algorithm to find the length of the shortest path between vertices a and z in the following weighted graph. Please show your distinguished vertex set and distances for each iteration.
Dijkstra's algorithm is a useful tool for finding the length of the shortest path between two vertices in a weighted graph.
To solve this problem, we can start by creating a distinguished vertex set Q that contains all of the vertices in the graph, and assigning a distance of ∞ to each vertex in the set. Then, we can assign the starting vertex, a, a distance of 0.
Next, we can choose the vertex in Q with the shortest distance from the source vertex, a. This vertex is then removed from the set Q, and all of its adjacent vertices are evaluated and added to the set Q if they are not already in it. We then assign each adjacent vertex the distance of the selected vertex, plus the weight of the edge connecting it to the selected vertex.
Finally, we continue this process until the destination vertex, z, is removed from the set Q. At this point, the length of the shortest path between vertices a and z can be found by looking at the distance of the destination vertex.

At the point where the cost is the same, how much will it cost to bowl at both bowling centers?
Part A: The cost of bowling will be the same at both centers if 4 games are bowled. Part B: It will cost $10 to bowl at both Fannin Lanes and Fun Time Lanes for 4 games.
Describe Bowling Games Cost?The cost of bowling games can vary depending on a number of factors, including the location, time of day, and day of the week. Generally, bowling alleys charge per game or per hour, with additional fees for shoe rentals and any other amenities or services.
The cost per game can range from a few dollars to upwards of $10 or more, depending on the location and other factors. Some bowling alleys also offer discounted rates for children, seniors, or members of certain groups.
Part A:
Let's assume that the number of games to be bowled is 'x'. The total cost of bowling at Fannin Lanes is 2.5x + 2, and at Fun Time Lanes it is 2x + 4. We need to find the number of games where the cost of bowling at both centers is the same.
2.5x + 2 = 2x + 4
0.5x = 2
x = 4
Therefore, the cost of bowling will be the same at both centers if 4 games are bowled.
Part B:
Using the value of 'x' found in Part A, we can find the cost of bowling at both centers.
At Fannin Lanes: 2.5(4) + 2 = 10
At Fun Time Lanes: 2(4) + 4 = 12
Therefore, it will cost $10 to bowl at both Fannin Lanes and Fun Time Lanes for 4 games.

Tiana is told to carry out the following polynomial division: (2x^(3)+4x^(2)-9x-18)-:(x+5)
The final answer is 2x^(2)-6x+21 with a remainder of -123. In polynomial division notation, this can be written as (2x^(2)-6x+21)-123/(x+5).
The polynomial division that Tiana is told to carry out is (2x^(3)+4x^(2)-9x-18)-:(x+5). To carry out this division, we can use long division.
Divide the first term of the dividend, 2x^(3), by the first term of the divisor, x. This gives us 2x^(2), which we write above the division symbol.
Multiply the divisor, x+5, by the first term of the quotient, 2x^(2), to get 2x^(3)+10x^(2).
Subtract this result from the dividend to get -6x^(2)-9x-18.
Repeat the process with the new dividend, -6x^(2)-9x-18. Divide the first term, -6x^(2), by the first term of the divisor, x, to get -6x, which we write above the division symbol next to 2x^(2).
Multiply the divisor, x+5, by the new term in the quotient, -6x, to get -6x^(2)-30x.
Subtract this result from the new dividend to get 21x-18.
Repeat the process with the new dividend, 21x-18. Divide the first term, 21x, by the first term of the divisor, x, to get 21, which we write above the division symbol next to 2x^(2)-6x.
Multiply the divisor, x+5, by the new term in the quotient, 21, to get 21x+105.
Subtract this result from the new dividend to get -123, which is our remainder.
So, the final answer is 2x^(2)-6x+21 with a remainder of -123. In polynomial division notation, this can be written as (2x^(2)-6x+21)-123/(x+5).

running track in the shape of an oval is shown. The ends of the track form semicircles. A running track is shown. The left and right edges of the track are identical curves. The top and bottom edges of the track are straight lines. The track has width 56 m and length of one straight edge 130 m. What is the perimeter of the inside of the track? HELP PLEASE INEED THIS
The perimeter of the inside of the track is approximately 354.36 meters.
What is the circumference?
In geometry, the circumference is the perimeter of a circle or ellipse.
To find the perimeter of the inside of the track, we need to find the length of the inside edge of the track and add it to twice the length of the semicircles at each end.
The inside edge of the track is formed by two parallel lines, each offset by a distance of 56 m from the outer edge. The length of this edge is equal to the length of the long straight edge minus twice the offset distance:
length of inside edge = 130 m - 2(56 m)
length of inside edge = 18 m
The length of each semicircle at each end is equal to half the circumference of a full circle with a radius equal to the width of the track (56 m). Therefore, the length of both semicircles is:
2 x (1/2 x 2π x 56 m) = 2π x 56 m
Adding the length of the inside edge to twice the length of the semicircles, we get:
perimeter of inside track = 18 m + 2π x 56 m
perimeter of inside track = 18 m + 112π m
the perimeter of the inside track ≈ 354.36 m (rounded to two decimal places)
Hence, the perimeter of the inside of the track is approximately 354.36 meters.

Assume that y = C(a)^x is an exponential function. Why can a not equal zero?
Answer:
In the exponential function y = C(a)^x, the value of a is the base of the exponent, which determines how fast the function grows or decays. If a were equal to zero, then any value of x would result in y being equal to zero, which would make the function flat and unchanging. Therefore, a cannot be equal to zero in an exponential function, as this would result in an undefined or meaningless expression. Additionally, any number raised to the power of zero is equal to 1, so an exponential function with a base of zero would also violate this mathematical rule.

The composition of the permutation (3 5 ) three times is (3 5) and the permutation (1 2 4) to the power of 2023 is (1 2 4)
The composition of the permutation (3 5 ) three times is (3 5) and the permutation (1 2 4) to the power of 2023 is (1 2 4).For part (c), we can find the composition of the permutation (3 5) three times by applying the permutation to itself three times. The first time we apply it, we get (5 3), the second time we get (3 5), and the third time we get (5 3) again. Since the permutation (5 3) is the same as the original permutation (3 5), the composition of the permutation (3 5) three times is (3 5).For part (d), we can find the permutation (1 2 4) to the power of 2023 by applying the permutation to itself 2023 times. Since the permutation (1 2 4) is a cycle of length 3, applying it to itself 3 times will give us the identity permutation (1 2 4)(1 2 4)(1 2 4) = (1)(2)(4). Therefore, we can reduce the exponent of 2023 to 2023 mod 3 = 1, and the permutation (1 2 4) to the power of 2023 is the same as the permutation (1 2 4) to the power of 1, which is (1 2 4).

FIND THE DOMAIN
The domain of the function is: {(x, y, z) | x ≠ 0, y ≠ -3x, z ≠ -2x, 2x + z ≠ -2xy/3}.
What is the domain?
To find the domain of the function, we need to identify any values of x, y, or z that would make the denominator(s) of the function equal to zero. Division by zero is undefined, so any such values must be excluded from the domain.
For the first term, the denominator is z + 2x, which is equal to zero when z = -2x.
Therefore, we must exclude this value from the domain.
For the second term, the denominator is 3x + y, which is equal to zero when y = -3x.
Therefore, we must exclude this value from the domain as well.
For the third term, the denominator is 6x² + 3xz + 2xy. Factoring out 3x from the second and third terms in the denominator gives:
6x² + 3xz + 2xy = 3x(2x + z) + 2xy
This expression is equal to zero when either 3x = 0 (i.e., x = 0) or 2x + z = -2xy/3.
Therefore, we must exclude x = 0 and any values of z that satisfy the equation 2x + z = -2xy/3.

seems appropriate for further analysis. f(x)=1.3x^(4)-5.7x^(2)+3.71,[-4,4,-8,14]
To further analyze the function f(x)=1.3x^(4)-5.7x^(2)+3.71 on the interval [-4,4,-8,14], we can find the critical points, relative extrema, and inflection points of the function.
First, let's find the critical points by taking the derivative of the function and setting it equal to zero:
f'(x)=5.2x^(3)-11.4x
0=5.2x^(3)-11.4x
0=x(5.2x^(2)-11.4)
x=0, x=±√(11.4/5.2)
So the critical points are x=0, x=±1.4656
Next, let's find the relative extrema by using the second derivative test:
f''(x)=15.6x^(2)-11.4
f''(0)=-11.4<0, so x=0 is a relative maximum
f''(1.4656)=11.4>0, so x=1.4656 is a relative minimum
f''(-1.4656)=11.4>0, so x=-1.4656 is a relative minimum
Finally, let's find the inflection points by setting the second derivative equal to zero:
0=15.6x^(2)-11.4
x=±√(11.4/15.6)
x=±0.8544
So the inflection points are x=±0.8544
Overall, the function f(x)=1.3x^(4)-5.7x^(2)+3.71 has a relative maximum at x=0, relative minimums at x=±1.4656, and inflection points at x=±0.8544 on the interval [-4,4,-8,14].

Find the values of a and b that make the following

f(x)={3−3x, , x<−1
{−2/3x^2+ax+b, x≥−1
The values of a and b that make the function both continuous and differentiable everywhere are a=-13/3 and b=11.
To make the function both continuous and differentiable everywhere, we need to find the values of a and b that make the two parts of the piecewise function equal at x=-1. This will ensure that there are no jumps or breaks in the function at x=-1, making it continuous and differentiable.
First, we plug in x=-1 into both parts of the function and set them equal to each other:
3−3(-1) = -2/3(-1)^2 + a(-1) + b
Simplifying both sides gives us:
6 = -2/3 + a + b
Next, we can rearrange the equation to solve for one of the variables in terms of the other. Let's solve for b in terms of a:
b = 20/3 - a
Now we can take the derivative of both parts of the piecewise function and set them equal to each other at x=-1 to ensure that the function is differentiable:
-3 = -4/3x + a
Plugging in x=-1 gives us:
-3 = 4/3 + a
Rearranging to solve for a gives us:
a = -13/3
Finally, we can plug this value of a back into the equation for b to find the value of b:
b = 20/3 - (-13/3) = 33/3 = 11
So the values of a and b that make the function both continuous and differentiable everywhere are a=-13/3 and b=11.

the table gives information about the lengths of time spent in minutes, it took some pupil to do their maths homework last week.
Using the lengths of the time spent we can plot the histogram by the values in the table.
What is a histogram how to draw a histogram?A histogram is a visual depiction of a frequency distribution with continuous classes that has been categorised.
To create a histogram, follow the steps shown below.
Mark the class intervals on the X-axis and the frequencies on the Y-axis to get started.
Both axes must have the exact same scales. Intervals between classes must be exclusive. Create rectangles with appropriate frequencies as the heights and bases acting as class intervals.
As the class limits are shown on the horizontal axis and the frequencies are shown on the vertical axis, a rectangle is constructed on each class interval.
If the intervals are identical, the height of each rectangle is proportional to the associated class frequency.
From the given information, we have the following:
Length of time (t) Frequency
0 ≤ t < 10 5
10 ≤ t < 25 24
25 ≤ t < 30 12
30 ≤ t < 50 8

The complete question is:
so thit i \( \mathrm{A}_{4} \) is targer than a \( \mathrm{B}_{2} . \mathrm{H} \) \[ \begin{array}{l} a=34, c=45, \quad A=194 \\ \rightarrow B_{1}=7 \cdot 3 \cdot \sim B_{2}= \\ -C_{1}= \\ b_{1}= \\ \
(\mathrm{A}_{4}\) is larger than \(\mathrm{B}_{2}\)
Yes, \(\mathrm{A}_{4}\) is larger than \(\mathrm{B}_{2}\). To show this, we can use the following equation:
\[\mathrm{A}_{4} = a \cdot c \cdot \mathrm{H}\]
and
\[\mathrm{B}_{2} = b_{1} \cdot c_{1}\]
Given that \(a = 34\), \(c = 45\), \(\mathrm{H} = 194\), \(b_{1} = 7\), and \(c_{1} = 3\), then \(\mathrm{A}_{4} = 34 \cdot 45 \cdot 194 = 291930\) and \(\mathrm{B}_{2} = 7 \cdot 3 = 21\). As \(291930 > 21\), \(\mathrm{A}_{4}\) is larger than \(\mathrm{B}_{2}\).

Last week, Cindy's Diner sold 7 milkshakes with whipped cream on top and 18 milkshakes without whipped cream. What percentage of the milkshakes had whipped cream?
Answer: The total number of milkshakes sold is 7 + 18 = 25.
The number of milkshakes sold with whipped cream is 7.
To find the percentage of milkshakes with whipped cream, we can use the formula:
percentage = (part/whole) x 100
Substituting the values, we get:
percentage = (7/25) x 100
percentage = 28
Therefore, 28% of the milkshakes had whipped cream.

Describe Distance?Distance refers to the measurement of the space or length between two points, objects, or locations. In mathematics, the distance between two points in a coordinate plane can be calculated using the distance formula, which is derived from the Pythagorean theorem. The distance formula is:
d = √[(x2 - x1)² + (y2 - y1)²]
In physics, distance is an important concept in understanding motion and energy. For example, the distance traveled by an object can be used to calculate its speed and acceleration, and the distance between two objects can affect the strength of their gravitational attraction.
In everyday life, distance is often used to describe physical space between objects, such as the distance between two buildings, the distance between two cities, or the distance between two people. It is also used in the context of travel, such as the distance between two destinations and the time it takes to travel that distance.

The complete question is:
What is the slope of the line that passes through the points ( 4 , − 6 ) and ( − 2 , 3)
Answer:
m = -3/2
Step-by-step explanation:
Slope = rise/run or (y2 - y1) / (x2 - x1)
Points (4, − 6) and (− 2, 3)
We see the y increase by 9 and the x decrease by 6, so the slope is
m = - 9/6 = -3/2
So, the slope of the line is -3/2
Nancy needs her to mark the numbers
and
on the number line. How many parts does she need between 1 and 2, and between -1 and -2, so that she can mark
and
?
If we consider the number line with rational number marked on it, then the number of parts to be present between 1 and 2 and -1 and -2 will be one part each.
A number line is a pictorial representation or drawing of numbers in which there are equal intervals between each number and is used to represent the real numbers on it. Real numbers are those numbers which may be positive or negative integers, rational numbers or irrational numbers. In general, a quantity which can be expressed as an infinite decimal expansion is called as a real number.
If we draw a number line and mark the points as 1, 2, 3,...,∞ and -∞,..., -3, -2, -1 on the right and left hand side of 0, then the intervals between each real number is equal to 1. Hence the number of parts between 1 and 2 is one part and -1 and -2 is one part. However, these parts may be subdivided into more parts to get more fine value (smaller value).
This value will be a fractional value between 1 and 2 or -1 and -2. Hence parts between two numbers on a number line can be infinity, but for sake of simplicity, one is taken in general case.
