The equation which can be represents a parabola in the standard form is given in the option C which is,

[tex]-3x +4y^2 - 2y+ 6 = 0[/tex]

The equation of parabola is the way to represent a parabola in a algebraic expression from using its vertex points.

The general form of the of the parabola can be given as,

[tex]y=a(x-h)^2+k[/tex]

Here, (h, k) are the vertex.

The equation of the parabola in the quadratic equation form can be given as,

[tex]y=ax^2+bx+c[/tex]

Lets check all the option. Equation given in the first option is,

[tex]4x^2 - 2x+ 3y^2 - y +1 = 0[/tex]

This option can not be converted in the above from of parabola.

Equation given in the second option is,

[tex]x^2+ x - 2y^2 - 4y +2 = 0[/tex]

This option can not be converted in the above from of parabola.

Third option is given as,

[tex]-3x +4y^2 - 2y+ 6 = 0\\-3x=-4y^2+2y-6[/tex]

Change the sign of both side of the equation as,

[tex]3x=4y^2-2y+6[/tex]

Divide by number 3 as,

[tex]x=\dfrac{4}{3}y^2-\dfrac{2}{3}y+2[/tex]

This can be compared with the form of parabola equation.

Hence, the equation which can be represents a parabola in the standard form is given in the option C which is,

[tex]-3x +4y^2 - 2y+ 6 = 0[/tex]

Answer:

2,160

Step-by-step explanation: since M is proportional to L^3 so when L=2 then L^3=8 so M=160 which means if L = 3

When L = 3, the value of M is 540. The relationship between M and L³ holds true.

When two variables, M and L, are directly proportional, it means that their ratio remains constant.

In this case, M is directly proportional to L³, which can be written as M = k × L³, where k is the constant of proportionality.

To find the value of k, we can use the given information when L = 2, and M = 160:

160 = k × 2³

160 = k × 8

k = 160 / 8

k = 20

Now that we have the value of k, we can find the value of M when L = 3:

M = 20 × 3³

M = 20 × 27

M = 540

So, when L = 3, the value of M is 540. The relationship between M and L³ holds true for any value of L when multiplied by the constant of proportionality k, which we found to be 20 in this case.

Assignment: Type one to two paragraphs that describe your models and relate them to the law of conservation of mass. Your document should:

Identify the names of the reactants and products in the reaction.

Identify the number of molecules that make up the reactants and products.

Identify the type and number of atoms in each molecule of the reactants and products.

Explain what happens during the chemical reaction.

Explain how mass is conserved during the chemical reaction

The name of the reactant in this reaction is called Calcium Carbonate (CaCO3) and the products in this reaction are Calcium Oxide (CaO) and Carbon Dioxide (CO2). There are 5 atoms total in calcium carbonate: one calcium atom, one carbon atom, and 3 oxygen atoms. In calcium oxide there are 2 atoms total: one calcium atom and one oxygen atom. In carbon dioxide there are 3 atoms total: one carbon and two oxygen atoms. So in the reaction the mass of the products stayed the same because according to the law of conservation, “in a closed or isolated system, matter cannot be created or destroyed. It can change forms but is conserved.” This can be seen in the reaction because no matter was made or destroyed, it was all just rearranged. To further explain, the law of mass conservation in chemistry states that, “in a chemical reaction, the mass of the products equals the mass of the reactants,” which further proves that no matter was created or destroyed, just rearranged. In conclusion, in the reaction the products had the same number of atoms as the reactant because no matter was destroyed or created, simply rearranged to create new products!

Answer: 60 degrees

Step-by-step explanation:

a triangle has a interior sum of 180°
90 + 30 = 120

180 - 120 = 60

Answer:

Step-by-step explanation:

Formula

P = 2*w + 2*L

Area = L*w

Givens

Area = P

L = 6

Create equation and Solve

LW = 2w + 2L

6w = 2w + 2*6

6w = 2w + 12                    Subtract 2w from both sides

6w - 2w = 12                     Combine

4w = 12                             Divide by 4

4w/4 = 12/4          

w = 3

Check

Area = 6*3 = 18

Perimeter = 2*3 + 2*6

Perimeter = 6 + 12           Combine

Perimeter = 18

It does check.

1. The length of the safety rail = Arc length is: 15.7 yd

2. The area of the deck = area of sector is: 78.5 yd²

Area of sector = ∅/360 × πr²

Arc length = ∅/360 × 2πr

1. Length of the safety rail = Arc length = ∅/360 × 2πr

= 90/360 × 2π(10)

= 15.7 yd

2. Area of the deck = area of sector = ∅/360 × πr²

The other factor of the polynomial [tex]\rm x^2+8x+15[/tex]  is  ( x + 3 )

It is given that the polynomial [tex]\rm x^2+8x+15[/tex] has one factor that is [tex]\rm (x+5)[/tex].

It is required to find another factor of the above polynomial.

Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.

We have a polynomial of degree two:

[tex]\rm = x^2+8x+15[/tex]

By using the factorization method we get:

[tex]\rm = x^2+8x+15\\\rm = x^2+3x+5x+15\\\rm = x(x+3)+5(x+3)\\\rm = (x+3)(x+5)\\[/tex]

Thus, the other factor of the polynomial [tex]\rm x^2+8x+15[/tex]  is  ( x + 3 )

Eliminating y right away is easiest. Add -3(equation 1) to equation 2, and add 3(equation 3) to equation 2:

-3(2x + y + 3z) + (-3x + 3y - 2z) = -3(3) + (-8)

-6x - 3y - 9z - 3x + 3y - 2z = -9 - 8

-9x - 11z = -17

9x + 11z = 17   [equation 1]

3(5x - y + 5z) + (-3x + 3y - 2z) = 3(13) + (-8)

15x - 3y + 15z - 3x + 3y - 2z = 39 - 8

12x + 13z = 31   [equation 2]

Eliminating x next is easier than eliminating z. Add -4(equation 1) to 3(equation 2):

-4(9x + 11z) + 3(12x + 13z) = -4(17) + 3(31)

-36x - 44z + 36x + 39z = -68 + 93

-5z = 25

z = 25/(-5)

z = -5

Plug this into either of the previous equations and solve for x :

9x + 11z = 17

9x + 11(-5) = 17

9x - 55 = 17

9x = 72

x = 72/9

x = 8

Plug x and z into any of the 3 original equations and solve for y :

2x + y + 3z = 3

2(8) + y + 3(-5) = 3

16 + y - 15 = 3

1 + y = 3

y = 2
