Write an equation for the parabola whose vertex is at (3, 6) and which
passes through (4, 4).
Answer:
f(x) = -2 (x - 3)² + 6Step-by-step explanation:
The vertex form of the equation of the parabola with vertex (h, k) is:
f(x) = a(x - h)² + k
so the equation of parabola with the vertex (3, 6) is
f(x) = a(x - 3)² + 6
passes through the point (4, 4) means: if x=4 then f(x)=4
4 = a(4 - 3)² + 6
4 -6 = a(1)² + 6 -6
-2 = a
Therefore the equation of parabla is:
f(x) = -2 (x - 3)² + 6
The vertex of a parabola is the maximum or the minimum point on the parabola.
The equation of the parabola is: [tex]\mathbf{y = -2(x -3)^2 + 6}[/tex]
The given parameters are:
[tex]\mathbf{Point = (x,y) =(4,4)}[/tex]
[tex]\mathbf{Vertex = (h,k) =(3,6)}[/tex]
The equation of parabola is:
[tex]\mathbf{y = a(x - h)^2 + k}[/tex]
Substitute values for x, y, h and k
[tex]\mathbf{4 = a(4 - 3)^2 + 6}[/tex]
[tex]\mathbf{4 = a(1)^2 + 6}[/tex]
[tex]\mathbf{4 = a + 6}[/tex]
Subtract 6 from both sides
[tex]\mathbf{a = -2}[/tex]
Substitute values for h, k and a in [tex]\mathbf{y = a(x - h)^2 + k}[/tex]
[tex]\mathbf{y = -2(x -3)^2 + 6}[/tex]
Hence, the equation of the parabola is:
[tex]\mathbf{y = -2(x -3)^2 + 6}[/tex]

2. Determine which of the following relations is a function. (Lesson 1-7)
F{-4,3), (-2,-2), (0, 2), (0,5)}
G{(-3, 1), (-3, 3), (-2,-1),(0,5)}
H(-4,-1),(-2,-1),(-1,-1), (3, 3)
J{(2, -5),-1,-1),(0,4), (2, -3)
Answer:
H
Step-by-step explanation:
H is the answer because in the simplest and easy way I can explain this is that it does have the same x in the table. If you look at F the x 0 repeats twice in the third and forth point. If you look at G the x -3 repeats twice in the first and second point. If you look at J the x 2 repeats twice in the first and forth point. The only answer choice does repeats any of the x's is H with the x's of -4, -2, -1, and 3. So with this being said H is the answer.
The y can repeat as a function just not the x.

1. How can you tell that a point on the graph is a maximum or minimum?
2. How would you explain average rate of change to a classmate who was absent today? What does it tell us and how do we find it?
Answer:
1) To see whether it is a maximum or a minimum, in this case we can simply look at the graph. f(x) is a parabola, and we can see that the turning point is a minimum. By finding the value of x where the derivative is 0, then, we have discovered that the vertex of the parabola is at (3, −4).

5c+4p=18.40 2c+4p=11.20
Answer:
c = 2.4
p = 1.6
Step-by-step explanation:
Given:
5c+4p=18.40
2c+4p=11.20
-1(2c+4p=11.20) <-- Distribute -1 so that you can cancel out p
-2c-4p=-11.20
5c+4p=18.40
+ -2c-4p=-11.20 <-- Add/simplify like terms
3c = 7.2 <-- Isolate c by dividing
c = 2.4
Now that we have c, we can find p
5c+4p=18.40
5(2.4)+4p=18.40 <-- Sub in 2.4 for c
12+4p=18.40 <-- Combine like terms in one side
4p=6.4 <-- Isolate p by dividing
p = 1.6

Answer:
Step-by-step explanation:
3 purple : 1 white
30 arangement will need so
minimum will need (3+1)=4 flowers per 30 arangements =120 flowers
minimum will be (90 purple: 30 white)
Answer:
120 flowers
Step-by-step explanation:
3 purple: 1 white
We know he wants to make 30 arrangement so
1 x 30=30 white flowers
3 x 30=90 purple flowers
30 + 90=120
You start at 1, 4. You move left five units and down seven units. where do you end?
Answer: -4,-3
Step-by-step explanation:
You start at the point (1,4) on the coordinate plane. The first number is on the x-axis, which moves horizontally and is divided down the middle by the y-axis. The left side of the x-axis is negative, while the right side of the x-axis is positive. The second number is on the y-axis, which moves vertically and is divided in half by the x-axis. The upper half of the y-axis is positive, while the lower side of the y-axis is negative.
If you start at the point (1,4) then the x coordinate would be 1 and the y coordinate would be 4. So moving left by 5 units you would be subtracting 5 from the x coordinate. Similarly, by moving down seven units you would be subtracting 7 from the y coordinate.
Solve:
1 - 5 = -4
-4 is your x coordinate
4 - 7 = -3
-3 is your y coordinate
The coordinate (-4,-3) is your answer

5u+u–u please tell me !
Answer: = UwU
Step-by-step explanation:
Answer:
5u
Step-by-step explanation:
Simplifying
5u + -1u = u + 15
Combine like terms: 5u + -1u = 4u
4u = u + 15
Solving for variable 'u'.
Move all terms containing u to the left, all other terms to the right.
Add '-1u' to each side of the equation.
4u + -1u = 15 + u + -1u
Combine like terms: 4u + -1u = 3u
3u = 15 + u + -1u
Combine like terms: u + -1u = 0
3u = 15 + 0
3u = 15
Divide each side by '3'.
u = 5
Simplifying
u = 5

Two bicyclists were racing toward each other when they were 98 miles apart. Three hours later they did not meet yet and the distance between them was 2 miles. How fast did they bike if one was 3mph slower than the other.
Let, speed of 1st bicyclist is x.
So, speed of 2nd bicyclist is x-3 .
We know, relative speed when two objects moves towards each other :
[tex]v = x + ( x-3 )\\\\v = 2x - 3[/tex]
Now, distance travelled in 3 hours is (98-2) miles .
So,
[tex]2x-3 = \dfrac{96}{3}\\\\2x - 3 = 32\\\\2x = 35\\\\x = 17.5\ mph[/tex]
Therefore, speed of bikes are 17.5 mph and 14.5 mph.
Hence, this is the required solution.
Norma's retirement party will cost $24 if she invites 12 guests. If there are 13 guests, how much will Norma's retirement party cost? Solve using unit rates.
Answer:
If there are 13 guests, it would cost Norma $26
Step-by-step explanation:
Since 12 guest equals 24 dollars all you have to do is divide 24/12 which would give you 2dollars. this means that she has to pay 2 dollars per guest. Multiply 13 becuase you want to know how much money it would cost with 13 guests and you get 26 dollars. Hope this helps.
Answer:
It'll cost $26 !
Step-by-step explanation:
if you set it up like this;
[tex]\frac{13}{x}= \frac{12}{24}[/tex]
you can see a few ways of solving this !
one way is cross multiplication .
13 x 24 = 312
312 / 12 = 26
