the sides of the smallest box are 30% of the length of the sides of the largest box. the volume of the largest box is 7784 cubic inches more than the volume of the smallest box. let x represent the length of the side of the largest box. write an equation that represents the difference in the volume of the two boxes.
The length of the side of the smaller box is 6 and the length of the side of the larger box is 20. The equation for the difference in volume of the boxes is, y3 - x3 = 7784 .
Let us consider the length of side of small box be x inch & length of large box be y inch.
Length of smallest box is 30% of the length of the side of the largest box
x=30%*y
= 30 * y / 100
x = 3y / 10
Volume of the smallest box is x3.
volume of the largest box is y3.
Volume of largest box is 7784 cubic inches more than the volume of smallest box. Therefore,
y3 = x3 + 7784
= (3y/ 10 )3 + 7784
= 27y3 / 1000 + 7784
y3 - 27y3 / 1000 = 7784
973 y3 / 1000 = 7784
973 y3 = 7784 * 1000
y3 = 7784 * 1000 / 973
y3 = 8000
y = 20
Now find the smaller side.
x = 3y / 10
putting the value of y this we get,
x = 3 * 20 / 10

What are the vertical asymptotes for the function f/x )= x 2 x 6 x 3 1?
The vertical asymptotes for the function f(x) = (x^2)(x-6)(x+3)^-1 are x=6 and x=-3.
The vertical asymptotes for the function f(x) = (x^2)(x-6)(x+3)^-1 are x=6 and x=-3. This is because the denominator can be factored into two linear expressions: x-6 and x+3. When either of these expressions equals 0, the fraction becomes undefined and a vertical asymptote is created. To find the asymptotes, set each linear expression in the denominator equal to 0 and solve for x. For x-6, x=6; for x+3, x=-3. Therefore, the vertical asymptotes of the function are x=6 and x=-3. When x is close to either of these values, the fraction will become very large, making the graph approach the vertical asymptotes without ever touching them.

The general case when G₁⊕G₂⊕G₃...⊕Gₙ is cyclic generated by (g₁, g₂, g₃,...,gₙ) is that the subgroups G₁, G₂, G₃,...., Gₙ are cyclic generated by g₁, g₂, g₃, ..., gₙ respectively.
G⊕H is cyclic
That is G⊕H = <(g, h)>
Let us choose an arbitrary element g₁ ∈ G, then as G⊕H is cyclic
(g₁, h₁) ∈ G⊕H = <( g, h)>
This means that there exists an integer x such that
(g₁, h₁) = (g, h)ˣ
(g₁, h₁) = (gˣ, hˣ)
that is g₁ = gˣ
implies g₁ ∈ <g>
that is G ⊆ <g> as g₁ is an arbitrary element belonging to G
But we know <g> ⊆ G
Hence G = <g>
Thus G is a cyclic group generated by g.
Similarly we can prove that H group is cyclic generated by h, that is H = <h>
So the general case is that G₁⊕G₂⊕G₃...⊕Gₙ is cyclic generated by (g₁, g₂, g₃,...,gₙ), then the subgroups G₁, G₂, G₃,...., Gₙ are cyclic generated by g₁, g₂, g₃, ..., gₙ respectively.

What are all the rational roots of the polynomial f x )= 20x 4 x 3 8x 2 x 12?
The rational roots of the given polynomial are +/- 1, +/- 2, +/- 3, +/- 4, +/- 6, +/- 12, +/- 1/2, +/- 1/4, +/- 1/5, +/- 1/10, and +/- 1/20.
To find the rational roots of the polynomial, we can use the Rational Root Theorem. This theorem states that if a polynomial of the form a_n*x^n + a_{n-1}x^{n-1} + ... + a_1x + a_0 has a rational root, then that root must be of the form p/q, where p is a divisor of a_0 and q is a divisor of a_n.
In this case, the polynomial is
f(x) = 20x^4 - 8x^3 - x^2 + 12x,
so a_0 = 12 and a_4 = 20. The divisors of 12 are 1, 2, 3, 4, 6, and 12. The divisors of 20 are 1, 2, 4, 5, 10, and 20. Therefore, the possible rational roots of the polynomial are
p/q = +/- 1, +/- 2, +/- 3, +/- 4, +/- 6, +/- 12, +/- 1/2, +/- 1/4, +/- 1/5, +/- 1/10, and +/- 1/20.
We can then test each of these values to see if they are actually roots of the polynomial. If a value is a root, then substituting it into the polynomial will result in a value of 0.
Therefore, the rational roots of the given polynomial are +/- 1, +/- 2, +/- 3, +/- 4, +/- 6, +/- 12, +/- 1/2, +/- 1/4, +/- 1/5, +/- 1/10, and +/- 1/20.

What is the arc length of the intercepted arc on the circle?
360° is all the way around a circle. The length of the intercepted arc is equal to the circumference of the circle.
Arc Length of a Circle:
Length. A practical way to determine the length of an arc in a circle is to plot two lines from the arc's endpoints to the center of the circle, measure the angle where the two lines meet the center, then solve for L by cross-multiplying the statement: measure of angle in degrees/360° = L/circumference.
Does arc length have to be in radians?
Arc length is a measurement of distance, so it cannot be in radians. The central angle, however, does not have to be in radians. It can be in any unit for angles you like, from degrees to arcsecs. Using radians, however, is much easier for calculations regarding arc length, as finding it is as easy as multiplying the angle by the radius.

Answer: see below
Step-by-step explanation:
The table is based on the rule y=-2x+5
let's use the last numbers as an example. x=10 and y= -15
since we know the values of x and y, we can substitute them into the rule equation
-15=-2(10)+5, see how I replaced y with 15 and x with 10?
Now we solve and see if they match.
-15=-20+5
-15=-15
since they match, they are correct.
Basically, replace x in the rule with the x values in the table, and if the y value is the same as the y value in the table, it is correct.

There are nine numbers in this set, so the median is the fifth number. The fifth number in this set is 14, so the median is 14.
The median of a set of numbers is the value that is exactly in the middle of the set when it is ordered from least to greatest. In this case, the set of numbers is 13, 16, 12, 14, 19, 12, 14, 13, 14. When we order this set from least to greatest, we get 12, 12, 13, 13, 14, 14, 14, 16, 19. There are nine numbers in this set, so the median is the fifth number. The fifth number in this set is 14, so the median is 14.
To find the median, we first need to arrange the numbers in order from least to greatest. If there is an odd number of numbers in the set, the median is the middle number. If there is an even number of numbers in the set, the median is the average of the two middle numbers. In this case, there are nine numbers in the set, so the median is the middle number.

How do u solve 4x 2y =- 12?
To solve this equation, use the distributive property to rewrite it as 4x - 2y = 12. Then, solve the equation using either addition or subtraction.
To solve the equation 4x 2y = -12, the first step is to use the distributive property to rewrite the equation as 4x - 2y = 12. This allows us to solve the equation using either addition or subtraction. If we choose to use addition, we can add 2y to both sides of the equation to get 4x + 2y = 12. We can then subtract 2y from both sides to get 4x = 12 - 2y. Dividing both sides of the equation by 4 gives us the solution x = (12 - 2y)/4. If we choose to use subtraction, we can subtract 2y from both sides of the equation to get 4x - 2y = 12. We can then add 2y to both sides to get 4x = 12 + 2y. Dividing both sides of the equation by 4 gives us the solution x = (12 + 2y)/4. In either case, the solution is x = (12 ± 2y)/4.
Addition:
4x + 2y = 12
4x = 12 - 2y
x = (12 - 2y)/4
Subtraction:
4x - 2y = 12

The two distinct real number zeros of f(x) left parenthesis, x, right parenthesis are -2 + sqrt(7) and -2 - sqrt(7).
The discriminant of a polynomial is a quantity that determines the number of distinct real roots of a polynomial equation. For a polynomial of degree n, the discriminant is calculated as the square of the coefficient of the nth degree term multiplied by the product of the coefficients of the remaining terms, minus the square of the product of the coefficients of the lower degree terms. In the case of [tex]f(x)=3x^2+12x+5[/tex], the discriminant is given by[tex]D=12^2 - 4*3*5 = 144 - 60 = 84.[/tex]
Since the discriminant is greater than 0, it follows that the polynomial equation has two distinct real number zeros. To find the zeros of the equation, we must solve the equation by setting it equal to zero and factorising it. Doing so, we find that the zeros are given by [tex]x = (-12 +/- sqrt(84))/6 = -2 +/- sqrt(7)[/tex]. Hence, the two distinct real number zeros of f(x) are -2 + sqrt(7) and -2 - sqrt(7).
