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

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

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

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

There are 1,600 students in the school.
There are 250 students in the school.
Answers
The number of students in the school are represented by percentages
The number of students in the school is 1600
Let the number of students in the school be n.
So, the equation from the question is:
[tex]\mathbf{10\% \times n = 160}[/tex]
Divide both sides by 10%
[tex]\mathbf{n = \frac{160}{10\%}}[/tex]
Express 10% as decimal (0.10)
[tex]\mathbf{n = \frac{160}{0.10}}[/tex]
[tex]\mathbf{n = 1600}[/tex]
Hence, the number of students in the school is 1600

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
