Determine the equation for the parabola graphed below.
y =
x2 +
x +
Answer:
[tex]\large\boxed{y=\dfrac{1}{2}x^2-2x+1}[/tex]
Step-by-step explanation:
The vertex form of an equation of a parabola:
[tex]y=a(x-h)^2+k[/tex]
(h, k) - vertex
a - leading coefficient in equation y = ax² + bx + c
From the grap we can read coordinates of the vertex (2, -1) and y-intercept (0, 1).
Therefore h = 2, k = -1
Put the values of h, k and coordinates of the y-intercept to the equation of parabola:
[tex]1=a(0-2)^2-1[/tex] add 1 to both sides
[tex]1+1=a(2)^2-1+1[/tex]
[tex]2=4a[/tex] divide both sides by 4
[tex]\dfrac{2}{4}=\dfrac{4a}{4}\\\\\dfrac{1}{2}=a\to a=\dfrac{1}{2}[/tex]
Therefore we have the equation:
[tex]y=\dfrac{1}{2}(x-2)^2-1[/tex]
Convert to the standard form:
[tex]y=\dfrac{1}{2}(x-2)^2-1[/tex] use (a - b)² = a² - 2ab + b²
[tex]y=\dfrac{1}{2}(x^2-2(x)(2)+2^2)-1[/tex]
[tex]y=\dfrac{1}{2}(x^2-4x+4)-1[/tex] use the distributive property
[tex]y=\dfrac{1}{2}x^2-\dfrac{1}{2}\cdot4x+\dfrac{1}{2}\cdot4-1[/tex]
[tex]y=\dfrac{1}{2}x^2-2x+2-1[/tex] combine like terms
[tex]y=\dfrac{1}{2}x^2-2x+1[/tex]
Please help!! Which table shows a proportional relationship between x and y?
Answer: The second table
Step-by-step explanation:
For the table to show proportional relationship between x and y , then they must have a common ratio. that is x/y must be the same throughout
Table 1
[tex]x_{1}[/tex] = 1 [tex]y_{1}[/tex] = 2
[tex]x_{2}[/tex] = 3 [tex]y_{2}[/tex] = 5
[tex]x_{3}[/tex] = 4 [tex]y_{3}[/tex] = 8
[tex]x_{4}[/tex] = 7 [tex]y_{4}[/tex] = 14
[tex]\frac{x_{1}}{y_{1}}[/tex] = 1/2
[tex]\frac{x_{2}}{y_{2}}[/tex] = 3/5
[tex]\frac{x_{3}}{y_{3}}[/tex] = 4/8 = 1/2
[tex]\frac{x_{4}}{y_{4}}[/tex]= 7/14 = 1/2
Since the ratio is not the same throughout , then x and y are not proportional
Table 2
[tex]x_{1}[/tex] = 7 [tex]y_{1}[/tex] = 1
[tex]x_{2}[/tex] = 14 [tex]y_{2}[/tex] = 2
[tex]x_{3}[/tex] = 28 [tex]y_{3}[/tex] = 4
[tex]x_{4}[/tex] = 35 [tex]y_{4}[/tex] = 5
[tex]\frac{x_{1}}{y_{1}}[/tex] = 7/1 = 7
[tex]\frac{x_{2}}{y_{2}}[/tex] = 14/2 = 7
[tex]\frac{x_{3}}{y_{3}}[/tex] = 28/4 = 7
[tex]\frac{x_{4}}{y_{4}}[/tex]= 35/5 = 7
Since the ratio is the same throughout , it means that x and y are proportional.
Doing the same for table 3 and 4 , x and y are not proportional

Note: Since you missed to add the figure. So, after a little research I am kind of able to find the figure and hence, assuming it as a reference. Hence, I am attaching the figure and solution of that figure is also visible in the same figure. Please check the attached figure (a)
Answer:
Segment B'D' will be parallel to segment BD and will be shorter than segment BD. Please see the attached figure (a) for better understanding.
Step-by-step explanation:
As we know that there are certain rules when a quadrilateral is dilated by a certain scale centered around a certain point.
So,
Let suppose P(a, b) is the point.
The dilation rule by a scale factor of 1 over 3 or (1/3) centered around (1, 2) is
P(a, b) → [tex]P(\frac{x+2}{3}, \frac{y+4}{3})[/tex]
Hence,
A(1, 2) → A'(1, 2)
B(2, 3) → B'(4/3, 7/3)
C(4, 2) → C'(2, 2)
D(2, 1) → D'(4/3, 5/3)
The attached figure show that if we draw the all these points in the coordinate plan i.e. A(1, 2), B(2, 3), C(4, 2), D(2, 1) and A'(1, 2), B'(4/3, 7/3), C'(2, 2), D'(4/3, 5/3), we can determine that Segment B'D' will be parallel to segment BD and will be shorter than segment BD.

A landscaper installed a circular sprinkler system using 50.25 feet of copper tubing to create the circle. To the nearest whole foot, what is the diameter of the circular sprinkler
Answer:
4 foot
Step-by-step explanation:
√50.25 / 3.1416 = 4
The diameter of the circular sprinkler is 16 feet.
Explanation:To find the diameter of the circular sprinkler, we can use the formula for the circumference of a circle: C = πd, where C is the circumference and d is the diameter. In this case, we are given the length of the copper tubing used, which is equal to the circumference. So we can rearrange the formula to solve for the diameter: d = C/π. Plugging in the given values, we have d = 50.25/π. Using the value of π as approximately 3.14, we can calculate the diameter to the nearest whole foot.
d ≈ 50.25/3.14 ≈ 16.01 feet
Therefore, the diameter of the circular sprinkler to the nearest whole foot is 16 feet.

In the 2006 Winter Olympics, Sweden won 3 medals more than China. Germany
secured one more than twice the number of medals bagged by sweden. It 54
medals were won in all, how many medals did Germany secure?
Final answer:
To find out how many medals Germany secured in the 2006 Winter Olympics, we denote the number of medals Sweden won as S and create an equation based on the problem's description. Solving for S, we find that Sweden won 14 medals, so Germany, with one more than twice the number of Sweden's medals, secured 29 medals in total.
Explanation:
The question requires us to solve a problem that involves understanding and creating equations based on the given information.
Let's denote the number of medals Sweden won as S. According to the problem, China won S - 3 medals, and Germany won 2S + 1 medals. The total number of medals won by all three countries is 54, so the equation to represent this information is:
S + (S - 3) + (2S + 1) = 54
By combining like terms, we get:
4S - 2 = 54
Now, we will solve for S:
4S = 56 ⇒ S = 14
Now that we know Sweden won 14 medals, we can determine the number of medals Germany secured, which is 2S + 1:
2(14) + 1 = 29
Therefore, Germany secured 29 medals in the 2006 Winter Olympics.

After completing the fraction division 8 divided by 1/6, Patel used the multiplication below to check his work. 1/48 x 6 = 1/48 x 6/1 = 6/48 = 1/8 which is the most accurate description of patels work? A. Patel found the correct quotient and checked his work using multiplication correctly. B. Patel found the correct quotient but checked his work using multiplication incorrectly. C. Patel found an incorrect quotient but checked his work using multiplication correctly. D. Patel found an incorrect quotient and checked his work using multiplication incorrectly.
Answer:
D. Patel found the incorrect quotient and checked his work using multiplication incorrectly.
Step-by-step explanation:
The dividend is [tex]8,[/tex] the divisor is [tex]\dfrac{1}{6}.[/tex] Divide the dividend by the divisor (division by fraction means multiplication by its reciprocal):
[tex]8\div \dfrac{1}{6}=8\times \dfrac{6}{1}=8\times 6=48,[/tex]
so the quotient is 48, not [tex]\dfrac{1}{48}.[/tex]
To check the answer, Patel has to multiply the quotient by the divisor to get the dividend. Check answer:
[tex]48\times \dfrac{1}{6}=\dfrac{48}{6}=8[/tex]
Hence, Patel found the incorrect quotient and checked his work using multiplication incorrectly.
The most accurate description of Patel's work is option D. Patel found an incorrect quotient and checked his work using multiplication incorrectly. therefore, option D. Patel found an incorrect quotient and checked his work using multiplication incorrectly.
Patel initially calculated 8 divided by 1/6 as 1/48, which is incorrect.
The correct quotient is 48.
When Patel multiplied 1/48 by 6, he got 1/8, which is also incorrect.
The correct result should be 48, not 1/8.
So, Patel's division was incorrect, and his check using multiplication was also incorrect.
In summary, Patel made an error in the initial division and didn't accurately check his work using multiplication, leading to an incorrect final result in both cases.

Aaron is going to a carnival that has games and rides. Each game costs $2.75 and each ride costs $4.75. Aaron spent $20.50 altogether at the carnival and the number of games he played is twice the number of rides he went on. Determine the number of games Aaron played and the number of rides Aaron went on.
Answer:
Step-by-step explanation:
2.75g + 4.75r = 20.50
g = 2r
2.75(2r) + 4.75r = 20.50
5.50r + 4.75r = 20.50
10.25r = 20.50
r = 20.50 / 10.25
r = 2 <==== Aaron went on 2 rides
g = 2r
g = 2(2)
g = 4 <==== Aaron played 4 games
check...
2.75g + 4.75r = 20.50
2.75(4) + 4.75(2) = 20.50
11 + 9.5 = 20.50
20.50 = 20.50 (correct)
find the domain of the function below if the domain is {-1,0,2} f(x)=x^2 -2x+3
Answer:
The Range is {3, 6}.
Step-by-step explanation:
The correct question is
Find the range of the function below if the domain is {-1,0,2} f(x)=x^2 -2x+3
we know that
The domain represents all possible values of x.
The range represents all possible values of f(x)
Substitute all of the possible x-values (domain) into the formula to find all possible f(x) values (the range).
For x=-1
[tex]f(-1)= (-1)^{2} - 2(-1) + 3[/tex]
[tex]f(-1)=1+2+ 3[/tex]
[tex]f(-1)=6[/tex]
For x=0
[tex]f(0)= (0)^{2} - 2(0) + 3[/tex]
[tex]f(0)=0-0+ 3[/tex]
[tex]f(0)=3[/tex]
For x=2
[tex]f(2)= (2)^{2} - 2(2) + 3[/tex]
[tex]f(2)=4-4+ 3[/tex]
[tex]f(2)=3[/tex]
therefore
The Range is {3, 6}.

plz help asap will give u brainliest :)
Answer:
Step-by-step explanation:
the first day he used 30 cups
the second day he used 15% of the remaining cups...a total of 90 cups were used on second day.
so 15%of the remaining cups = 90.....so if u let x be the total cups, then the remaining cups would be x - 30
15% of (x - 30) = 90.....turn ur percent to a decimal..." of " means multiply
0.15(x - 30) = 90
0.15x - 4.5 = 90
0.15x = 90 + 4.5
0.15x = 94.5
x = 94.5 / 0.15
x = 630 total cups <==
lets check..
start with 630 cups....used 30 the first day....leaving u with 600 cups....15% of the remaining cups = 90.....so 15% of 600 = 90....lets check it
15%of 600 = 0.15(600) = 90...yep, thats correct....there were 630 cups in the new un-opened box
Answer:
630
Explanation:
15% * number of remaining cups = 90
15% * (x-30) = 90
0.15(x-30) = 90
0.15x - 4.5 = 90
0.15x = 94.5
x = 630
