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

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
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.

Find the ratio (red to blue) of the perimeters of the similar triangles. Write your answer in simplest form.
Answer:
[tex] \frac{12}{7} [/tex]
Step-by-step explanation:
Side length of red ∆ = 12
Side length of blue ∆ = 7
Given that the red ∆ is similar to the blue ∆, therefore the ratio of their corresponding sides = the ratio of their perimeter.
The ratio of the perimeter of red ∆ to perimeter of blue ∆ = side length of red ∆ / side length of blue ∆
[tex] = \frac{12}{7} [/tex]
The ratio (red to blue) of the perimeters of the similar triangles is 12:7
Assuming that the similar triangles are equilateral triangles, then all their sides will be equal.
Perimeter of a triangle = s1 + s2 + s3
For the red triangle;
Perimeter of the red triangle = 12 + 12 + 12
Perimeter of the red triangle = 36
For the blue triangle:
Perimeter of the blue triangle = 7 + 7 + 7
Perimeter of the blue triangle = 21
Taking the ratio of their perimeters;
Ratio of red to blue = 36:21 = 12:7
Hence the ratio (red to blue) of the perimeters of the similar triangles is 12:7

Decompose and use the distributive property to find the product of 9 × 8.53.
76.77
72.72
76.5
79.2
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
First option. 76.77
