Which equation represents a parabola? 4x2 – 2x 3y2 – y 1 = 0 x2 x – 2y2 – 4y 2 = 0 –3x 4y2 – 2y 6 = 0 2x2 y2 – 4y 6 = 0.
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]
What is equations of the parabolas?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]

A company manufactures two types of electric hedge trimmers, one of which is cordless. The cord-type trimmer requires 2 hours to make, and the cordless model requires 6 hours. The company has only 600 work hours to use in manufacturing each day, and the packaging department can package only 200 trimmers per day. If the company profits for the cord-type model for $36.50 and the cordless model for $109.50, how many of each type should it produce per day to maximize profits?
Answer:
P=$14600The company should produce 100cordless and 100 cord-typeStep-by-step explanation:
This is a linear programming question
let the cordless trimmer be X

A rectangle’s perimeter and its area have the same numerical value. The length of the rectangle is 6. What is the width of the rectangle in units?.
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.

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

ii. identify the number of molecules that make up the reactants and products.
iii. identify the type and number of atoms in each molecule of the reactants and products.
iv. explain what happens during the chemical reaction.
v. explain how mass is conserved during the chemical reaction
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!
