Answer:

I want to say the answer is D

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

A filled in circle located on the number line indicates x can equal that value

If the circle is open then x cannot equal that value

An arrow pointing right from the circle indicates that x is greater

An arrow pointing left from the circle indicates that x is less

Since the number line has a filled in circle at x = 3 and the arrow is pointing to the right , thus

x ≥ 3 → D

EXPLANATION

The given parabola has a focus at (8,0) and directrix at x=-8.

The equation of this parabola is of the form:

[tex] {y}^{2}=4px[/tex]

Where p is the the distance from the vertex to the focus.

Since the vertex is at the origin,the distance from the vertex to the focus (8,0) is p=8.

[tex] {y}^{2} = 4(8)x[/tex]

Answer:

12 cookies and 10 brownies

Step-by-step explanation:

Eder needs 15 cookies and 5 brownies.

Given in the question is Eder needs 6 cookies and 2 brownies for 4 plates.

We have to calculate the cookies and brownies required for 10 plates.

Let's first calculate the cookies by unitary method.

∵ 4 plates required cookies = 6 cookies

∴  1 plate will require cookies = 6/4

∴ 10 plates will require cookies = 6×10/4 = 15

Similarly we will calculate the brownies.

∵ 4 plates required number of brownies = 2

∴ 1 plate will require = 2/4 brownies

∴ 10 plates will require = 2×10/4 = 5 brownies

Therefore 15 cookies and 5 brownies will be required for 10 plates.

Add the ratios together:

5 +4 = 9

Divide the total amount by t his number:

54 / 9 = 6

Now multiply each side of the ratio by 6:

Sam = 5 x 6 = £30

Bethan = 4 x 6 = £24

Answer:

A coordinate plane graph is shown. A line passes through the y-axis at 3 and through the point 2 comma 4. Which equation best represents the line?

y=6x+3

Step-by-step explanation:

Answer:

a. The coordinates of the vertex are (2 , 3)

b. The focal length of the parabola is 8

c. The equation, in standard form, of the parabola is (y - 3)² = -8(x - 2)²

Step-by-step explanation:

* Lets revise the equation of a parabola  

- If the equation is in the standard form (y − k)² = 4p(x − h), then:

# Use the given equation to identify h and k for the vertex, (h , k)

# Use the value of k to determine the axis of symmetry, y = k

# Use h , k and p to find the coordinates of the focus, (h + p , k)

# Use h and p to find the equation of the directrix, x = h − p

# The endpoints of the focal diameter,  (h + p , k ± 2p)

# The focal length is I4pI

* Now lets solve the problem

∵ The parabola has focus at (0 , 3)

∵ The coordinates of its focus, (h + p , k)

∴ h + p = 0 ⇒ (1)

∴ k = 3

∵ Its directrix at x = 4

∵ The equation of the directrix, x = h − p

∴ h - p = 4 ⇒ (2)

- Add (1) and (2) to find h and p

∴ h + p + h - p = 0 + 4 ⇒ add the like terms

∴ 2h = 4 ⇒ divide both sides by 2

∴ h = 2

- Substitute the value of h in (1)

∴ 2 + p = 0 ⇒ subtract 2 from both sides

∴ p = -2

a. ∵ h = 2 and k = 3

∵ The vertex of the parabola is (h , k)

∴ The coordinates of the vertex are (2 , 3)

b. ∵ The focal length is I4pI

∵ p = -2

∴ The focal length = I4 × -2I = I-8I = 8

∴ The focal length of the parabola is 8

c. ∵ The equation in the standard form is (y − k)² = 4p(x − h)

∵ h = 2 , k = 3 , p = -2

∴ The equation is (y - 3)² = 4(-2)(x - 2)²

∴ The equation is (y - 3)² = -8(x - 2)²

∴ The equation, in standard form, of the parabola is (y - 3)² = -8(x - 2)²

Answer:

The correct option is C) 27

Step-by-step explanation:

Consider the provided figure.  

Volume of a cone is: [tex]V=\frac{1}{3}\pi r^2h[/tex]

The area of base of the cone is = area of circle = [tex]\pi r^2[/tex]

Volume of the cone is 45 in³ and the area of base is given as 5 in²

Therefore, [tex]45=\frac{1}{3}\pi r^2h[/tex]

and [tex]5=\pi r^2[/tex]

Substitute the value of [tex]\pi r^2=5[/tex] in  [tex]45=\frac{1}{3}\pi r^2h[/tex]

[tex]45=\frac{1}{3}\times 5\times h[/tex]

[tex]45\times \frac{3}{5}=h[/tex]

[tex]h=27[/tex]

Hence, the height of the cone is 27 in.

Therefore, the correct option is C) 27

Gabby received

7 nickels

10 dimes

3 quarters

Step-by-step explanation:

Let

x----> the number of dimes

y----> the number of nickels

z---> the number of quarters

Remember that

1 dime=$0.10

1 nickel=$0.05

1 quarter=$0.25

we know that

0.10x+0.05y+0.25z=2.10 ------> equation A

x=y+3-----> equation B

z=y-4 -----> equation C

substitute equation B and equation C in equation A and solve for y

0.10(y+3)+0.05y+0.25(y-4)=2.10

0.10y+0.30+0.05y+0.25y-1=2.10

0.40y=2.10-0.30+1

0.40y=2.80

y=7 nickels

Find the value of x

x=y+3 -----> x=7+3=10 dimes

Find the value of z

z=y-4 -----> z=7-4=3 quarters

Things that make me skeptical: No evidence is provided, the company also claims that its washing machine produces 4000 joules of output for ever 3000 joules of input, and there is no possible way of creating a joule output larger than the input, unless your using coils to increase electricity, but that's not what washing machines have inside of their machinery. Washing machines don't have mini Tesla coils inside their machinery!

Part b) The distance on a map between the airport and the restaurant is 1.68 inches and the total distance on a map between Joseph's house and the restaurant is 4.21 inches

Step-by-step explanation:

Part a) The actual distance between Joseph's house and the airport is 24 miles. How far apart are Joseph's house and the airport on the map?

we know that

The scale of a map is 1 inch : 9.5 miles

so

using proportion

Find the distance on a map if the  actual distance between Joseph's house and the airport is 24 miles

Let

x-----> the distance on a map

1/9.5=x/24

x=24/9.5=2.53 inches

Part b) Joseph traveled from his house to the airport. He then traveled another 16 miles past the airport to a restaurant. How many inches on the map represent this distance?

we know that

The scale of a map is 1 inch : 9.5 miles

Answer:

x = 12

Step-by-step explanation:

Since all 3 angles are congruent then the triangle is equilateral, thus all 3 sides are also congruent.

Equate any 2 of the sides and solve for x

5x - 22 = 3x + 2 ( subtract 3x from both sides )

2x - 22 = 2 ( add 22 to both sides )

2x = 24 ( divide both sides by 2 )

x = 12

Answer:

The value of x is 12

Step-by-step explanation:

* Lets talk about the equilateral triangle

- The three sides of the triangle are equal in length

- The three angles of the triangle are equal in measure

- To find the measure of each one divide the sum of the measures

  of the angles of the triangle by 3

∵ The sum of the measure of the angles in any triangle = 180°

∴ The measure of each angle in the equilateral Δ = 180° ÷ 3 = 60°

* Now lets solve the problem

- From the figure the three angles have the same mark, that means

 the three angles are equal in measure

∵ m∠A = m∠B = m∠C

∴ Δ ABC is equilateral triangle

∴ AB = BC = AC

- WE can use any two sides of them to find the value of x

∵ AB = 4x - 10

∵ BC = 3x + 2

∵ AB = BC

∴ 4x - 10 = 3x + 2 ⇒ add 10 and subtract 3x from both sides

∴ 4x - 3x = 2 + 10 ⇒ add the like terms

∴ x = 12

- To check the answer substitute the value of x in the 3 sides to

 find the length of each side (they must have the same length)

∵ AB = 4x - 10

∴ AB = 4(12) - 10 = 48 - 10 = 38 units

∵ BC = 3x + 2

∴ AB = 3(12) + 2 = 36 + 2 = 38 units

∵ AC = 5x - 22

∴ AB = 5(12) - 22 = 60 - 22 = 38 units

- All the sides are equal, then the value of x is right

* The value of x is 12
