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.

Answer: Y= -5x+4

Step-by-step explanation:

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.

The 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.

Step-by-step explanation:

Lets find the slope of the line first so we can write the equation.

Counting the slope, we can see the slope of the line is [tex]\frac{3}{1}[/tex] or 3, so we have to write the equation of the line in slope intercept form [tex]y=mx+b[/tex] where m is the slope and b is the y intercept.

We know that the y intercept is -4 by looking at the graph, so we simply plug in our slope and y intercept.

[tex]y=3x-4[/tex]

To tell if equations are parallel or perpendicular:

Parallel:  The slope is the same

Perpendicular: The slope is the opposite reciprocal

Lets look at the equations and see if there parallel:

1. [tex]y=-3x+10[/tex] is neither.

2. The equation of the line is in point slope form, however we are already given the slope in the equation. The slope is [tex]-\frac{1}{3}[/tex], which is the opposite reciprocal of 3, therefore it is perpendicular.

3. [tex]\frac{1}{3}[/tex] is not the opposite reciprocal of 3, it is neither.

4. The equation of the line is in standard form, which means we must solve for y to get it in slope intercept form

[tex]-3x+y=1[/tex]
Subtract -3x on both sides

[tex]y=1-(-3x)[/tex]

Simplify

[tex]y=3x+1[/tex]

The equation has the same slope, so it is parallel.

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 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 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

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.

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.

Answer:

When you make 3x + y = -8 into a slope intercept equation it will become the same question

3x + y = -8

-3x      |       -3x

y = -3x - 8

(a) By help of induction, it is proved the sequence is monotonically increasing for all n ≥ 1.

(b) The sequence is bounded above by 3 for all n ≥ 1.

(c)  Applying the Monotonic Sequence Theorem, it is proved that the limit of the sequence exists.

(d) limn→[infinity] an is 2.

(e) The series X[infinity] n=1 an is convergent

(a) To show that the sequence is monotonically increasing, we can use induction. Let's first consider the base case, n = 1. We have a1 = √2 and a2 = √2 + a1 = √2 + √2 > a1, so the sequence is increasing for n = 1. Now, let's assume that the sequence is increasing for n = k, so ak+1 > ak. Then, for n = k+1, we have ak+2 = √2 + ak+1 > √2 + ak = ak+1, so the sequence is also increasing for n = k+1. Therefore, by induction, the sequence is monotonically increasing for all n ≥ 1.

(b) To show that the sequence is bounded above by 3, we can also use induction. Let's first consider the base case, n = 1. We have a1 = √2 < 3, so the sequence is bounded above by 3 for n = 1. Now, let's assume that the sequence is bounded above by 3 for n = k, so ak < 3. Then, for n = k+1, we have ak+1 = √2 + ak < √2 + 3 = 3.2 < 3, so the sequence is also bounded above by 3 for n = k+1. Therefore, by induction, the sequence is bounded above by 3 for all n ≥ 1.

(c) By the Monotonic Sequence Theorem, if a sequence is both monotonically increasing and bounded above, then the limit of the sequence exists. Since we have shown that the sequence is monotonically increasing in part (a) and bounded above by 3 in part (b), we can conclude that the limit of the sequence exists.

(d) To find the limit of the sequence, we can use the fact that an+1 = √2 + an for all n ≥ 1. Taking the limit of both sides as n approaches infinity, we get limn→∞ an+1 = limn→∞ √2 + an. Since the limit of the sequence exists, we can write this as L = √2 + L, where L is the limit of the sequence. Solving for L, we get L = 2, so the limit of the sequence is 2.

(e) To determine whether the series X∞ n=1 an is convergent, we can use the fact that the limit of the sequence is 2. Since the sequence converges to 2, the terms of the sequence are getting closer and closer to 2 as n approaches infinity. This means that the terms of the series are getting smaller and smaller, and the series is convergent.

Step-by-step explanation:

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.

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.

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.

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:
