Place an inequality symbol between each fraction pair. State reasoning or rationale. (8)/(9),(10)/(12) -(5)/(6),-(6)/(8) Circle fractions that are completely simplified. State how this was determined.
No common factors
For the first set of fractions, the inequality symbol would be <, as 8/9 is less than 10/12. The rationale for this is that when fractions have different denominators, the fraction with the smaller denominator is always less. For the second set of fractions, the inequality symbol would be >, as -5/6 is greater than -6/8. The rationale for this is that when two fractions have the same denominator, the fraction with the larger numerator is always greater. The fractions that are completely simplified are 8/9, -5/6, and -6/8. This is because they cannot be reduced any further as they have no common factors.

Answer:
32 in
Step-by-step explanation:
You want the missing diameter of the smaller of two similar cylinders, where the larger is 12 ft in diameter and 3 ft high, while the smaller is 8 inches high.
Similar figuresThe linear dimensions of similar figures have the same ratio.
The ratio of the diameter to the height of the larger figure is ...
(12 ft)/(3 ft) = 4
The smaller figure will also have a diameter that is 4 times the height:
d = 4 × 8 in = 32 in
The missing dimension is 32 inches.
Create utilities for location and price combinations considering restrictions listed on the case study (200-level seats cannot be less than $60, 300-midcourt seats cannot be less than $35).
Based on the results,
1.which location & price combination is the best alternative to raise prices? Which location & price combination is the best alternative to lower prices?
2. How much could administration raise 300 mid-level seat prices to give them the same level of attractiveness as the next best alternative? Should they raise the prices to the calculated level? Please explain.
1. To raise prices, the best alternative is to increase the price of 200-level seats to $60 or higher. To lower prices, the best alternative is to reduce the price of 300-midcourt seats to $35 or lower.
2. Administration could raise 300 mid-level seat prices to make them as attractive as the next best alternative. To calculate the optimal level, the cost of the next best alternative (200-level seats) needs to be compared with the cost of the 300-midcourt seats. If the cost of the 300-midcourt seats is lower than the cost of the 200-level seats, administration should raise the price of the 300-midcourt seats to match the cost of the 200-level seats. The attractiveness of the two options should be assessed to determine if the 300-midcourt seats should be priced at the calculated level.

The function f(x) is shown on the graph.
The graph shows a downward opening parabola with a vertex at 3 comma 25, a point at negative 2 comma 0, a point at 8 comma 0, a point at 0 comma 16, and a point at 6 comma 16.
What is the standard form of the equation of f(x)?
f(x) = x2 − 6x + 16
f(x) = x2 + 6x + 16
f(x) = −x2 − 6x + 16
f(x) = −x2 + 6x + 16
Therefore, the equation of the parabola is:
f(x) = -(x - 3)² + 25
f(x) = -x² + 6x + 16
So the answer is f(x) = -x² + 6x + 16.
What does a vertex in mathematics mean?Typically, the intersection of two or more lines or edges forms a vertex, a singular point on a mathematical object. Graphs, polygons, polyhedra, and angles are the shapes that contain vertices most commonly. Nodes are another name for vertices in a graph.
Since the vertex of the parabola is at (3, 25), we know that the equation of the parabola is of the form:
f(x) = a(x - 3)² + 25
where "a" is a constant that determines the shape of the parabola. We also know that the parabola passes through the points (-2, 0), (8, 0), (0, 16), and (6, 16).
Let's plug in the coordinates of one of the points on the parabola to find the value of "a". For example, if we plug in the coordinates of the point (0, 16), we get:
16 = a(0 - 3)² + 25
-9 = 9a
a = -1
Therefore, the equation of the parabola is:
f(x) = -(x - 3)² + 25
f(x) = -x² + 6x + 16
So the answer is f(x) = -x² + 6x + 16.

Let l, m, and n be three lines; if n Im and m ll then 1 || n. Let l, m, and n be three lines; if I || m and m || n then 1 || n. Let k, l, m, and n be four lines; if k 11,11 m and m In then k \ n.
This property can be applied to any number of lines as long as they are all parallel to the same line.
The statement "if n I| m and m ll then 1 || n" is not valid as the symbols used are not correct. The correct statement should be "if l || m and m || n then l || n". This means that if line l is parallel to line m and line m is parallel to line n, then line l is also parallel to line n. This is known as the transitive property of parallel lines.
Similarly, the statement "if k 11,11 m and m In then k \ n" is not valid as the symbols used are not correct. The correct statement should be "if k || l, l || m, and m || n then k || n". This means that if line k is parallel to line l, line l is parallel to line m, and line m is parallel to line n, then line k is also parallel to line n. This is also an application of the transitive property of parallel lines.
In conclusion, the transitive property of parallel lines states that if two lines are parallel to the same line, then they are also parallel to each other. This property can be applied to any number of lines as long as they are all parallel to the same line.

The restrictions on x, when (x+4)/(5x-1) is divided by (3x+12)/(6x), can be written in the form x!
The restrictions on x are x = 1/5 and x = 0.
The restrictions on x, when (x+4)/(5x-1) is divided by (3x+12)/(6x), can be found by looking at the denominators of each fraction. The restrictions are values of x that would make the denominator equal to zero, which would make the fraction undefined.
For the first fraction, (x+4)/(5x-1), the restriction is when 5x - 1 = 0. Solving for x, we get:
5x = 1
x = 1/5
For the second fraction, (3x+12)/(6x), the restriction is when 6x = 0. Solving for x, we get:
x = 0
Therefore, the restrictions on x are x = 1/5 and x = 0. These values of x cannot be used in the original expression because they would make the denominator equal to zero and the expression undefined.

The region corresponding to the statement P(z<1.4) is the area to the left of z=1.4 on a standard normal distribution. This represents the probability of obtaining a z-score less than 1.4.
The region corresponding to the statement P(-c < z < c) = 0.2 is the area between two values, -c and c, on a standard normal distribution that contains 20% of the total area under the curve. This represents the probability of obtaining a z-score between -c and c.
The region corresponding to the statement P(|z|>c) = 0.2 is the area to the left of z=-c and to the right of z=c on a standard normal distribution that contains 20% of the total area under the curve. This represents the probability of obtaining a z-score that is greater than c or less than -c.
The first statement, P(z < 1.4), refers to the probability that the random variable z is less than 1.4. To sketch this region, we would shade the area to the left of the value 1.4 on the number line.
The second statement, P(-c < z < c) = 0.2, refers to the probability that the random variable z is between -c and c, and that this probability is equal to 0.2. To sketch this region, we would shade the area between -c and c on the number line, and adjust the values of c until the shaded area represents 0.2 of the total area under the curve.
The third statement, P(c < z < k) = -0.2, refers to the probability that the random variable z is between c and k, and that this probability is equal to -0.2. To sketch this region, we would shade the area between c and k on the number line, and adjust the values of c and k until the shaded area represents -0.2 of the total area under the curve.

Mr. and Mrs. Doran have a genetic history such that the probability that a child being born to them with a certain trait is 0.82. If they have four children, what is the probability that exactly two of their four children will have that trait? Round your answer to the nearest thousandth.
Using binomial distribution, the probability of exactly two of their four children having the trait is 0.13 (rounded to the nearest thousandth).
What is the probability that a child born to them with a certain trait is 0.82This is a binomial distribution problem with n = 4 trials (number of children) and p = 0.82 probability of success (having the trait) for each trial.
The probability of exactly two children having the trait can be calculated using the binomial distribution formula:
P(X = 2) = (4C2) * 0.82^2 * (1 - 0.82)^(4-2)
where (4C 2) is the number of ways to choose 2 children out of 4.
Using a calculator or statistical software, we get:
P(X = 2) = (4 C 2) * 0.82^2 * (1 - 0.82)^(4-2)
= 6 * 0.82^2 * 0.18^2
= 0.13

The following is the formula for an exponential function that traverses two points:
f(x) = abˣ
Where a is the initial value and b is the growth rate.
To find the formula for an exponential function that passes through the two points given, we can plug in the values of x and y into the formula and solve for a and b.
For the first set of points, (0,4) and (2,64), we can plug in the values of x and y into the formula and solve for a and b:
4 = ab⁰
64 = ab²
Simplifying the first equation gives us:
a = 4
Substituting this value of a into the second equation gives us:
64 = 4b²
Solving for b gives us:
b = √(64/4) = 4
Therefore, the formula for the exponential function that passes through the two points (0,4) and (2,64) is:

The width of Aubrey's bed is 40 inches and the distance between opposite corners is 85 inches. What is the length of Aubrey's bed?
Answer: 75 inches
Step-by-step explanation:
Using Pythagorean's Theorem, a² + b² = c², let a represent the length of the bed.
a² + 40² = 85²
a² + 1600 = 7225
a² = 5625
a = 75
The length of the bed is 75 inches.
Hope this helps!
Answer: 75
Step-by-step explanation: We can think of Aubrey’s bed as a triangle, Since the area doesn't matter. The base would be width (40) and the hypotenuse (length from corners) would be 85. So, since A^2+B^2=C^2 and c is 85 and a is 40. The equation is 40^2+?^2=85^2 so if we solve the numbers whit exponents we would get this: 1600+?=7225. Then we would just subtract 1600 from 7225 which is: 5625. Now we are not done. 5625 is just the square version of 5625. So we would need to find the square root. Which is 75.
Fill in the blank so that the ordered pair is a solution of y=22−9x
.
One possible ordered pair that is a solution of the equation y = 22 - 9x is (2, 4).
What is an ordered pair, and how can we find solutions of a linear equation?
An ordered pair is a pair of numbers (x, y) that represents a point on a coordinate plane. In algebra, we often use ordered pairs to represent solutions of equations, where the x-coordinate represents a variable and the y-coordinate represents the corresponding value of the expression.
To find solutions of a linear equation, we can substitute different values of the variable into the equation and solve for the corresponding values of the expression.
Find the ordered pair:
We are given the equation y = 22 - 9x, and we want to find an ordered pair that is a solution of the equation. To do this, we can choose a value of x and then use the equation to find the corresponding value of y.
Let's choose x = 2. Then, we can substitute x = 2 into the equation and solve for y:
y = 22 - 9(2)
y = 22 - 18
y = 4
Therefore, when x = 2, y = 4, which means the ordered pair (2, 4) is a solution of the equation.
We could also check this by graphing the equation and verifying that the point (2, 4) lies on the line represented by the equation.

Step-by-step explanation:
The steepest road in the world is Canton Avenue in Pittsburgh, Pennsylvania, with a grade of 37%. Grade is defined as the amount of vertical rise (in ft) over 100 ft of horizontal distance (so a road that rises 6 ft over 100 ft of horizontal distance is 6 100 = .06 = 6%). If the 37% grade of Canton Avenue goes for 21 ft of horizontal distance, how much does it rise? What angle does this grade make with the ground?
The steepest road in the world, Canton Avenue in Pittsburgh, Pennsylvania, has a grade of 37%. This means that for every 100 ft of horizontal distance, the road rises 37 ft. To find out how much the road rises for 21 ft of horizontal distance, we can use the formula:
rise = grade × distance
Plugging in the values we have:
rise = 0.37 × 21
rise = 7.77 ft
Therefore, the road rises 7.77 ft for 21 ft of horizontal distance.
To find the angle that this grade makes with the ground, we can use the formula:
tan θ = rise ÷ distance
Plugging in the values we have:
tan θ = 7.77 ÷ 21
tan θ = 0.37
θ = tan^-1(0.37)
θ = 20.3°
Therefore, the grade of Canton Avenue makes an angle of 20.3° with the ground.

the product (2x^(4)y)(3x^(5)y^(8))is equivalent towhat polynomial must be added to x^(2)-2x+6 so that the sum is 3x^(2)+7x
The polynomial that must be added to x^(2)-2x+6 is 2x^(2) + 9x - 6.
To find the product of the two polynomials (2x^(4)y)(3x^(5)y^(8)), we need to use the distributive property and combine like terms.
The distributive property states that a(b+c) = ab+ac. So, we can distribute the first polynomial to each term in the second polynomial:
(2x^(4)y)(3x^(5)y^(8)) = (2x^(4)y)(3x^(5)) + (2x^(4)y)(y^(8))
Next, we can combine like terms by adding the exponents of the variables:
= 6x^(4+5)y^(1+8)
= 6x^(9)y^(9)
So, the product of the two polynomials is 6x^(9)y^(9).
To find the polynomial that must be added to x^(2)-2x+6 so that the sum is 3x^(2)+7x, we can set up an equation:
x^(2)-2x+6 + (a+bx+cx^(2)) = 3x^(2)+7x
Then, we can rearrange the equation to solve for the polynomial:
a+bx+cx^(2) = 3x^(2)+7x - x^(2) + 2x - 6
a+bx+cx^(2) = 2x^(2) + 9x - 6

Evaluate the integral by changing to cylindrical coordinates. 7 −7 49 − y2 − 49 − y2 11 xz dz dx dy x2 + y2
The value of the triple integral is 49π ln(49) - 24.5π.
To evaluate this triple integral using cylindrical coordinates, we need to express the limits of integration in terms of cylindrical coordinates. We can convert the Cartesian coordinates to cylindrical coordinates as follows:
x = r cos(θ)
y = r sin(θ)
z = z
The region of integration is a cylinder centered at the origin with radius 7 and height 14 (from -7 to 7 in the y-direction). Therefore, the limits of integration are:
0 ≤ r ≤ 7
0 ≤ θ ≤ 2π
-7 ≤ z ≤ 7
Substituting these limits of integration and the Cartesian-to-cylindrical conversion into the integral, we get:
∫∫∫ 7 −7 (49 - [tex]y^2 - r^2[/tex]) / ([tex]x^2 + y^2)[/tex] dz dx dy
= ∫[tex]0^7[/tex]∫[tex]0^2π[/tex] ∫-7^7 (49 - [tex]r^2[/tex]sin^2(θ) - r^2) / (r^2cos^2(θ) + r^2sin^2(θ)) dz r dθ dr
= ∫0^7 ∫0^2π ∫-7^7 (49 - r^2) / r^2 dz r dθ dr
= ∫0^7 ∫0^2π [ln|49-r^2|] from -7 to 7 dθ dr
= ∫0^7 2π ln|49-r^2| dr
This integral is now a single-variable integral that can be evaluated using integration by substitution or by parts. Let u = 49 - r^2 and du = -2r dr. Then:
∫0^7 2π[tex]ln|49-r^2|[/tex] dr = ∫49^0 -πln|u| du/-2
= π/2 [u ln|u| - u] from 49 to 0
= π/2 [49 ln(49) - 49] = 49π ln(49) - 24.5π
