2.) I have a question about how to get the vertex of a parabola and it’s vertex form.



Hope this is plausible enough.

Possible Answer:

1. I understand that when graphed, a quadratic function has the shape of a parabola.

2. I have a question about the quadratic function when graphed. The lines can point up or down, but why can't the function go left or right?

Determine m∠DFG :))))

Answers

Answer:  127 (choice D)

=========================================================

Explanation:

We can apply the remote interior angle theorem.

The exterior angle DFG is far away from the remote interior angles FGH and GHF. In other words, the exterior angle is not adjacent to these remote interior angles.

The remote interior angles add to this exterior angle.

(angle FGH) + (angle GHF) = angle DFG

(89) + (5x-7) = 14x+1

5x + 82 = 14x + 1

82-1 = 14x-5x

81 = 9x

9x = 81

x = 81/9

x = 9

If this is the case, then,

angle DFG = 14*x+1 = 14*9+1 = 127

Answer:

(2,4)

Step-by-step explanation:

substitute the [tex]y = 2x[/tex] for the [tex]y[/tex] in [tex]x = -y + 6[/tex]

[tex]x = -(2x) + 6[/tex]

[tex]x = -2x + 6[/tex]

[tex]3x = 6[/tex]

[tex]x = 2[/tex]

next take [tex]x = 2[/tex] and input it into [tex]y = 2x[/tex]

[tex]y = 2(2)[/tex]

[tex]y = 4[/tex]

Answers

The question is incomplete. Here is the complete question.

Mr. Jackson decides to build a planter in the shape of a cube fo rhis wife. The top of the planter will be open so his wife can plant and water her flowers. The perimeter of the bottom of the planter is 12 feet.

How many square feet of material does Mr Jackson need to build the planter?

(a) 27 square feet

(b) 45 square feet

(c) 60 square feet

(d) 720 square feet

Answer: 45 square feet

Step-by-step explanation: A cube is a regular solid with six square faces.

Square is a quadrilateral with 4 right angles and 4 equal sides. So a cube is solid formed by 6 squares.

Perimeter is the sum of all the sides. For a square, perimeter is given by

P = 4s

Then, side of the bottom is

[tex]s=\frac{P}{4}[/tex]

[tex]s=\frac{12}{4}[/tex]

s = 3

Area of a square is

[tex]A=s^{2}[/tex]

[tex]A=3^{2}[/tex]

A = 9

The planter is a cube with 5 faces, because the top is open. Then, total area is

[tex]A_{t}=9+9+9+9+9[/tex]

[tex]A_{t}=[/tex] 45

Mr Jackson will need 45 square feet of material to build the planter.

Answer:

45 feet

Step-by-step explanation: A cube is a regular solid with six square faces.

Square is a quadrilateral with 4 right angles and 4 equal sides. So a cube is solid formed by 6 squares.

Perimeter is the sum of all the sides. For a square, perimeter is given by

P = 4s

Then, side of the bottom is

s = 3

Area of a square is

A = 9

The planter is a cube with 5 faces, because the top is open. Then, total area is

45

Mr Jackson will need 45 square feet of material to build the planter.

Answer:

c=20 e=114 d=46 dec=180

Step-by-step explanation:

y=5

Answer:

m∠C = 32°

m∠D = 82°

m∠DEC = 66°

Step-by-step explanation:

Exterior Angle Theorem says that the degree measure that with an angle forms a straight line (Ex. Angle DEF in the picture) is equal to the sum of the two other angles in the triangle. This means that the measure of angle DEF is equal to the measure of angle DCE plus the measure of angle CDE. This would mean that 9y + 1 + 3y + 5 = 114, meaning that 12y + 6 = 114, which means that 12y = 108, which means that y = 9. If we plug 9 in for all of these values, we get that angle D is 9 * 9 + 1, which is 82 and that angle C is 3 * 9 + 5, which is 32. Next, we know that the sum of angles in a triangle is 180, so we subtract 32 and 82 from 180 to find the measure of angle DEC, and this is 66 degrees.

Suppose that a phone that originally sold for $800 and is worth 3/5 of its value each year after it is released. Write an equation for the value of the phone, y years after it is released.

Answers

Answer:

v = 800 - 3/5y

Step-by-step explanation:

v = value

y = years

The original cost/value was 800 dollars which means you would have to subtract the 3/5 decrease in value each year.

v = 800 - 3/5y

Answer:

ABCD is a rhombus => AC is perpendicular with BD

=> AC = 2(2n + 5) = 30

<=> 2n + 5 = 15

=> n = 5

with n = 5 => AC/2 = 15

BD/2 = 4.5 - 3 = 17

BC² = (AC² + BD²)/4 = 514/4 = 128.5

=> BC = 11.34

Answer:

Step-by-step explanation:

The question is what does 2n + 5 represent? Is it 1/2 the line or all of AC. There seems to be a run on ambiguous questions. I'm going to assume that 2n + 5 is AC -- all of it. And 4n-3 is all of BD.

AC = 30

2n + 5 = 30      Subtract 5 from both sides.

2n = 30 - 5

2n = 25            Divide by 2

n = 25/2

n = 13.5

====================

BD = 4n - 3

BD = 4*13.5 - 3

BD = 54 - 3

BD = 51

The perimeter of a rectangle is 260 yards. The length is 30 yards greater than the width. Find the dimensions of the rectangle.

Answers

Answer:

width: 50 yards

length: 80 yards

Step-by-step explanation:

I would write an equation to start

x = width

260 = 2x + 2(x + 30)

260 = 4x + 60

200 = 4x

x = 50

Width = 50 yards

Length = width + 30

Length = 50 + 30

Length = 80 yards

The width of a rectangle is 2 inches smaller than its length. The perimeter is 24 inches. Find the length and width of the rectangle.

Answers

Answer:

7 inches and 5 inches

Step-by-step explanation:

The length the length and width of the rectangle be l and b.

Accodrding to question,

Width, b = l-2

Perimeter, P = 24 inches

We know that,

The perimeter of a rectangle is given by :

P = 2(l+b)

24 = 2(l+l-2)

12 = 2l-2

14=2l

l = 7 inches

Width, b = 7-2 = 5 inches

Hence, the length and width of the rectangle are 7 inches and 5 inches respectively.
