Write the equation of a parabola with directrix y=8 and focus (0,0)

Answers

9514 1404 393

Answer:

  y = -1/16x^2 +4

Step-by-step explanation:

The vertex is halfway between the focus and directrix, so is at (0, 4). The focus is 4 units below the vertex, so "p" = -4. For vertex (h, k) and focus-vertex distance p, the equation is ...

  y = 1/(4p)(x -h)^2 +k

Using the values we determined, this is ...

  y = -1/16x^2 +4

Benjamin decides to treat himself to breakfast at his favorite restaurant. He orders chocolate milk that costs \$3.25$3.25dollar sign, 3, point, 25. Then, he wants to buy as many pancakes as he can, but he wants his bill to be at most \$30$30dollar sign, 30 before tax. The restaurant only sells pancakes in stacks of 444 pancakes for \$5.50$5.50dollar sign, 5, point, 50.

Answers

Answer:

C. 3.25 + 5.50S ≤ 30

Step-by-step explanation:

The given parameters are;

Chocolate milk = $3.25

A stack of four pancakes = $5.50

Number of pancakes in one stack = 4

Let

S = number of stacks of pancakes Benjamin buys

Cost of the pancakes Benjamin buys = $5.5 × S

= 5.5S

The maximum amount Benjamin wants his bill to amount to = $30

The inequality is

Cost of chocolate milk + Cost of pancakes Benjamin buys ≤ $30

$3.25 + $5.50S ≤ $30

3.25 + 5.50S ≤ 30.

Option C is the correct answer

C) C 3.25 + 5.50 S ≤ 30

3.25+5.50S≤303, point, 25, plus, 5, point, 50, S, is less than or equal to, 30

76.77
72.72
76.5
79.2

Answers

Answer:

First option. 76.77

Step-by-step explanation:

The distributive property of the multiplication with respect to the sum can be written as:

[tex]x ( y + z ) = xy + xz[/tex]

We can take advantage of this property to find the product of 9*8.53 if we write:

8.53 = 8 + 0.53, thus:

[tex]9*8.53=9*(8+0.53)[/tex]

Applying the distributive property:

[tex]9*8.53=9*8+9*0.53[/tex]

Operating:

[tex]9*8.53=72+4.77=76.77[/tex]

Thus:

9*8.53=76.77

Tickets to a movie cost $11 for adults and $7 for students. A group of friends purchased 8 tickets
for $76. Write a system of equations to represent the situation. How many adult tickets and
student tickets were purchased

Answers

Answer:

5 Adult tickets were purchased and 3 student tickets were purchased.

Step-by-step explanation:

Write the problem as an equation like this

11x+7x=76

Now make an equation for the number of purchased tickets. Let x be adult and y be students.

x+y=8

Rewrite x + y = 8 as y = -x +8

Substitute y = -x + 8 into the first equation for y.

11x+7(-x+8)=76

11x+(-7x)+56=76

solve for 11x+(-7x)

4x+56+76

subtract 56 from both sides

4x=20

Divide both sides by 4

X=5

x + y = 8

5 + y = 8

y = 3

5 Adult tickets were purchased and 3 student tickets were purchased.

Create a list of steps, in order, that will solve the following

equation.
3(x + 5)+ 2 = 42.5

Solution steps (answer choices):

Multiply both sides by
2
Subtract 2 from both sides
Subtract 5 from both sides
Square both sides
Take the square root of both sides

We can get the distance of that linear equation just to put the values of A, B, and C.

For the line 4x - 3y = 2,
A = 4
B = -3
C = 2

If we put these into that equation,
d = √(2/4)^2+(2/(-3))^2
= √(1/2)^2+(2/(-3))^2
= √1/4 + 4/9

To solve this, we have to make the denominators in the square root.

√1/4 + 4/9
= √9/36 + 16/36
= √25/36

And this is gonna be

√5^2 / 6^2
