Answer:
The vertex is (6, -4)
Step-by-step explanation:
f(x) =(х – 8)(х – 4)
First find the zeros
0 = (х – 8)(х – 4)
0 = x-8 0 =x-4
x=8 x=4
The zeros are x=8 and x=4
The vertex is 1/2 way between the zeros
(8+4)/2 = 12/2 =6
To find the y value, substitute 6 into the function
f(6) = (6-8) (6-4)
= -2 (2) = -4
The vertex is (6, -4)

Please help me create the rational function that fits this graph!
PLEASE LOOK AT FILE ATTACHED!
WILL GIVE BRAINLIEST! THANK YOU
Answer:
According to the picture, we can have the function form as:
y = ax^2 + bx + c
The y-intercept is (0, 2) => c = 2
=> y = ax^2 + bx + c
The x-intercept is (-2, 0)
=> 4a - 2b = 0 (1)
The graph goes through (1, 1.5)
=> a + b + 2 = 1.5
=> a + b = -0.5 (2)
From (1) and (2)
=> 4a - 2(-a - 0.5) = 0
=> 6a + 1 = 0
=> a = -1/6 => b = -0.5 - (-1/6) = -1/2 + 1/6 = -15/30 + 5/30 = -10/30 = -1/3
=> y = (-1/6)x^2 -(1/3)x + 2
Hope this helps!

Bart recorded the amount of rain that fell in a desert in each month for one year. What was the total amount of rainfall in the desert that year? Line plot named as ALTDCMonthly Rainfall Amounts in One YearALTDC shows a number line from 0.0 to 1.1. The number line is divided into 22 equal parts. 1 dot on 0.4, 2 dots on 0.5, 1 dot on 0.6, 2 dots on 0.85, 1 dot on 0.95, 2 dots on 1.0, 2 dots on 1.05 and 1 dot on 1.1 is given. A. 9.85 inches B. 26.05 inches C. 7.25 inches D. 10.75 inches
Answer:
A. 9.85 inches
Step-by-step explanation:
In the graph we can see that 1 month has a rainfall of 0.4 in, 2 months have a rainfall of 0.5 in, 1 month has a rainfall of 0.6 in, 2 months have a rainfall of 0.85 in, 1 month has a rainfall of 0.95 in, 2 months have a rainfall of 1.0 in, 2 months have a rainfall of 1.05 in and 1 month has a rainfall of 1.1 in.
The total amount of rainfall in the desert that year was: 0.4 + 2*0.5 + 0.6 + 2*0.85 + 0.95 + 2*1.0 + 2*1.05 + 1.1 = 9.85 inches

Which expression has (x – a) as one of its factors?
A.–(x + a) – 2
B.–2(x + a)
C.(x – a) + 2
D.2(x – a)
i dont get this at all pls help im so lonely and confused...
Answer:
D
Step-by-step explanation:
When an expression is divided by its factor, there are no remainders.
Let's look at the number 6.
6= 1(6)= 2(3)
Thus, the factors of 6 are 1,2,3 and 6.
This is because 6 is divisible by all those numbers to give no remainders.
Let's look at the question again.
D. 2(x-a) is divisible by (x-a) since
[tex] \frac{2(x - a)}{x - a} = 2[/tex]
A.
[tex] \frac{ - (x + a) - 2}{x - a}[/tex]
This fraction cannot be simplified further
B.
[tex] \frac{ - 2(x + a)}{x - a} [/tex]
This fraction cannot be simplified either
C.
[tex] \frac{(x - a) + 2}{x - a} \\ = \frac{x - a}{x - a} + \frac{2}{x - a} \\ = 1 + \frac{2}{x - a} [/tex]
There is a remainder of 2 since 2 cannot be divided by (x-a). Thus, (x-a) is not a factor of this fraction.

Suri's age is 4 less than 3 times her cousin's age. Suri is 17 years old. Which method can be
used to find c her cousin's age?
Answer:
Add 4 to 17, then divide both sides by 3.
Step-by-step explanation:
Given that :
Suri's age is 4 less than 3 times her cousin's age
Suri is 17 years old
Let her cousin's age be c
Then ;
3c - 4 = 17
By adding 4 to 17; we have
3c = 17 + 4
3c = 21
Now, dividing both sides by 3 ; we have
3c/3 = 21/3
c = 7
The age of her cousin is 7 years
Answer:
Algebraic equation
Step-by-step explanation:
We would use an algebraic equation.
An algebraic equation is a mathematical statement in which two expressions are made equal to each other using the equal sign.
In this case the algebraic equation consists of constant, variables and algebraic operation.
One of the type of algebraic equation is a linear equation. The expression below relating suri's age with her cousin's is a linear equation.
We can derive equations from sentences that involves unknown values by representing them with variables such as x, y, etc.
Suri's age = 17years old
Let Suri's cousin's age = x
3 times her cousin's age = 3x
Suri's age = 4 less than 3 times her cousin's age = 3x-4
17 = 3x-4
3x = 17+4 = 21
x = 21/3
x = 7
Her cousins age = 3x = 3×7
Her cousins age = 21 years

lucy rolls 2 fair dice and adds the results from each. work out the probability of getting a total of 10
Answer:
The probability of obtaining the sum of 10 is 1/12 or 0.0833
Step-by-step explanation:
Given
2 fair dice
Required
Probability of obtaining the sum of 10
To solve this, we have to list out the sample space.
Sample space is the total possible sum that can be obtained when she rolls the dice.
Let the first die be represented with S1 and the second be represented with S2.
S1 = {1,2,3,4,5,6}
S2 = {1,2,3,4,5,6}
To get the sample space, we have to add individual elements of S1 and S2.
This is done as follows.
When S1 = 1 and S2 = {1,2,3,4,5,6}
Sum = 1+1, 1+2, 1+3, 1+4, 1+5, 1+6
Sum = 2, 3, 4, 5, 6, 7
When S1 = 2 and S2 = {1,2,3,4,5,6}
Sum = 2+1, 2+2, 2+3, 2+4, 2+5, 2+6
Sum = 3,4,5,6,7,8
Using the same pattern as used above
When S1 = 3 and S2 = {1,2,3,4,5,6}
Sum = 4,5,6,7,8,9
When S1 = 4 and S2 = {1,2,3,4,5,6}
Sum = 5,6,7,8,9,10
When S1 = 5 and S2 = {1,2,3,4,5,6}
Sum = 6,7,8,9,10,11
When S1 = 6 and S2 = {1,2,3,4,5,6}
Sum = 7,8,9,10,11,12
Writing out the Sum, will give us the sample space.
Sample Space = {2, 3, 4, 5, 6, 7, 3, 4, 5, 6, 7, 8, 4, 5, 6, 7, 8, 9, 5, 6, 7, 8, 9, 10, 6, 7, 8, 9, 10, 11, 7, 8, 9, 10, 11, 12}
The sample space has a total of 36 elements
To calculate the probability of obtaining the sum of 10,
We have to count the number of 10's in the sample space
Number of 10 = 3
Probability = Number of 10 / Number of Sample Space
Probability = 3 / 36
Probability = 1/12
Probability = 0.0833
Hence, the probability of obtaining the sum of 10 is 1/12 or 0.0833
Answer:
3/36 = 1/12
Step-by-step explanation:
Total Outcome - 36
Possible Outcome - 4,6 5,5 6,4 : 3
A bicycle depreciates at a rate of 15%. Theresa bought a bicycle for $250. How much should it be worth 6 years later?
Final answer:
The bicycle should be worth a value of $79.16 after 6 years.
Explanation:
To calculate the value of the bicycle 6 years later, we need to find the depreciated price. The bicycle depreciates at a rate of 15% per year, so after 6 years, it will be worth 85% of its original value.
First, we calculate the value after one year: $250 * 0.85 = $212.50. Then, for each subsequent year, we multiply the previous year's value by 0.85 to calculate the new value.
Therefore, the bicycle should be worth $212.50 * 0.85 * 0.85 * 0.85 * 0.85 * 0.85 = $79.16 after 6 years.

a) Work out the size of AOD.
b) Work out the size of angle ABC and give a reason for your answer.
Thanks in advance :)
Answer:
ABC = 31
Step-by-step explanation:
Angle AOC and ABC have the angle theorem: the angle subtended at the centre of the circle is double the angle at the circumference. Its quite hard to realise the layout, because angle AOC isn't between points A and C. If angle AOC moved to the right side of line AB, it would be easier to see. Of course we cannot do this, otherwise angle AOC wouldn't be the middle anymore. Hope this helped
(a). The angle AOD is 62 degrees.
(b). The angle ABC is 31 degrees.
(a). From given diagram, It is observed that triangle AOD is a right angle triangle.
The sum of all three angles in triangle is equal to 180 degrees.
[tex]\angle A +\angle O + \angle D = 180\\\\90 +\angle AOD +28=180\\\\\angle AOD=180-90-28=62[/tex]
(b). The central angle theorem states that the angle subtended by an arc at the center of the circle is double the angle subtended at any point on the circumference of the circle.
[tex]\angle ABC = \frac{1}{2} \angle AOD\\ \\\angle ABC=\frac{1}{2}*62=31[/tex]

Which transformations were used to create triangle J'K'L?
Answer:
I believe it's the second one
Step-by-step explanation:
A dilation factor of 1/2 and reflection across the x-axis that triangle JKL is dilated to form triangle J'K'L' which is the correct answer would be an option (C)
What is the Dilation?Dilation is a process for creating similar figures by changing the size.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
Here triangle JKL is dilated to form triangle J'K'L
Given that the coordinates for each of the shapes:
Regular:
J = -8, 6
K = -4, 6
L = -6, 2
Prime notation:
J' = -4, -3
K' = -2, -3
L' = -3, -1
We have to determine the dilation factor.
As we know dilation factor is the ratio of sides in the original image and the image after dilation.
Dilation factor = J'K'/JK
Dilation factor = 2/4 = 1/2
Hence, a dilation factor of 1/2 reflection across the x-axis that triangle JKL is dilated to form triangle J'K'L'
