Answer:
[tex]y = 2 {(x + 2)}^{2} + 62[/tex]
Step-by-step explanation:
vertex form is
[tex]y = a {(x - h)}^{2} + k \\ where \: (h. \: k) \: is \: the \: vertex[/tex]
our original equation
[tex]2 {x}^{2} + 8x + 70[/tex]
first we will find the x value using the formula
[tex]x = - \frac{b}{2a} \\ - \frac{8}{2(2)} = - \frac{8}{4} = - 2 \\ x = - 2 = h[/tex]
plug the value of x back into the original equation to solve for y
[tex]y = 2 {x}^{2} + 8x + 70 \\ y = 2 ({ - 2}^{2} ) + 8( - 2) + 70 \\ y = 2(4) - 16 + 70 \\ y = 8 - 16 + 70 \\ y = 78 - 16 \\ y = 62 = k[/tex]
substitute this back into our vertex form and not forgetting the coefficient a = 2
[tex]y = 2 {(x - ( -2))}^{2} + 62 \\ y = 2 {(x + 2)}^{2} + 62[/tex]

Which is the correct label of the parallel lines? Parallel lines a and b are shown. Points A and B lie on line a while points C and D lie on line b. The letters a and b are separated by two vertical lines. There is a horizontal line with arrows on either end over the letters A A. There is another horizontal line with arrows on either end over the letters C B. A vertical line with a horizontal line intersecting it at the bottom separates the two pairs. There is a horizontal line over the letter A with one arrow on the right end. There is a horizontal line over the letter B with one arrow on the right end. The letters are separated by two vertical lines. There is a horizontal line with arrows on either end over the letters A B. There is another horizontal line with arrows on either end over the letters C D. A vertical line with a horizontal line intersecting it at the bottom separates the two pairs.
Answer:

a || b will be the correct label for the parallel line so option (A) will be correct.
What are parallel lines?Two lines in the same plane that are equally spaced apart and never cross each other are said two lines in the same plane that are equally spaced apart and never cross each other to be parallel lines.
Parallel lines are those lines in which slopes are the same and the distance between them remains constant.
Given the two lines a and b as parallel.
If we want to show any two lines as parallel then we use |the | sign in between them.
Now in the given figure, A B C D are points on lines a and b so they will not be used to show parallel lines.
Hence "a || b will be the correct label for the parallel line".

HELP ASAP PLEASE 100 POINTS GIVEN!!!!!!!!
Smith was the top scorer in a women's professional basketball league for the 2006 regular season, with a total of 850 points. The number of two-point field goals that Lindsey made was 57 less than double the number of three-point field goals she made. The number of free throws (each worth one point) she made was 41 less than the number of two-point field goals she made. Find how many free throws, two-point field goals, and three-point field goals Lindsey Smith made during the 2006 regular season.
Given that :
Total point = 867
Let :
number of 3 point goals = p
Number of 2 point goals = 2p - 66
Number of 1 point goals = (2p - 66) - 36 = 2p - 102
Hence,
3p + 2(2p - 66) + 2p - 102 = 867
3p + 4p - 132 + 2p - 102 = 867
3p + 4p + 2p - 234 = 867
9p - 234 = 867
9p = 867 + 234
9p = 1101
p = 122.33
2 pointer = 2p - 66
2(122.33) - 66 = 178.67
1 point = 2p - 102
2(122.33) - 102
= 142.67
Given that :
Total point = 867
Let :
number of 3 point goals = p
Number of 2 point goals = 2p - 66
Number of 1 point goals = (2p - 66) - 36 = 2p - 102
Hence,
3p + 2(2p - 66) + 2p - 102 = 867
3p + 4p - 132 + 2p - 102 = 867
3p + 4p + 2p - 234 = 867
9p - 234 = 867
9p = 867 + 234
9p = 1101
p = 122.33
2 pointer = 2p - 66
2(122.33) - 66 = 178.67
1 point = 2p - 102
2(122.33) - 102
= 142.67

A project calls for three pieces of wood. The longest piece must be twice the length
of the middle-sized piece. The shortest piece must be 10 in. shorter than the middle-
sized piece. If a board 70 in. long is to be used, how long can each piece be?
Answer:
70,35,25
Step-by-step explanation:
Let longest piece = a = 70
Let medium piece = b = 35
Let shortest piece = c = 25
a=2b
70=2b
35=b
c+10=b
c+10=35
c=25

Answer:
[tex]650/725[/tex]
Step-by-step explanation:
The probability a flight will not be late is (flights that are not late)/(total flights).
If you're early or on time, you're not late. So, the probability is [tex](150+500)/(150+500+75)=\boxed{650/725}[/tex]

(a) Using Geometry Vocabulary, describe a sequence of transformations that maps
figure X onto figure Y.
(b) Write the Transformation Mapping Rule(s) for the sequence you described in part
(a).
Answer:
Translate figure X [tex]\left[\begin{array}{ccc}1\\0\\\end{array}\right][/tex], reflect figure X in the y-axis to give figure Y.
Step-by-step explanation:
It is very clear that shape X is being reflected in the y-axis to give shape Y. However, when reflecting shape X, it doesn't perfectly align with Y (it is off by 1 square).
So, we need to move shape X by 1 square so that when reflected in y-axis, it will align perfectly with shape Y. We can do this using a translation. We can see that if we move shape X one square to the right and no squares up or down, it will be reflected to give shape Y in the y-axis.
This leaves us with the column vector [tex]\left[\begin{array}{ccc}1\\0\\\end{array}\right][/tex]. And our final step is to write about the reflection that we identified earlier.
So the final answer is : Translate figure X [tex]\left[\begin{array}{ccc}1\\0\\\end{array}\right][/tex], reflect figure X in the y-axis to give figure Y.

What is the shape of this distribution?
A. Bimodal symmetric
B. Bimodal skewed

C. Unimodal symmetric
D. Unimodal skewed
E. Uniform
Answer:
Uniform
Step-by-step explanation:
The shape of the given histogram is uniform.
Option E is the correct answer.
We have,
A uniform histogram is a type of histogram where all the bars have approximately the same height, indicating that the data is evenly distributed across the range of values.
In other words, the frequency of occurrence for each value or interval is roughly the same.
For example, consider the following data set of 20 numbers:
{4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23}
If we create a histogram of this data set with five bars, each representing a range of four values (e.g., 4-7, 8-11, etc.), we would expect to see a uniform histogram with approximately the same height for each bar.
This indicates that the data is evenly distributed across the range of values.
Uniform histograms are useful for visualizing data that is evenly distributed or to identify outliers that are not consistent with the rest of the data. However, in some cases, a uniform histogram may not accurately represent the underlying distribution of the data, especially if there are gaps or clusters of data within certain ranges.
In such cases, other types of histograms or statistical methods may be more appropriate.
Thus,
The shape of the given histogram is uniform.

In the following diagram lines m are n parallel the measures of AEB, BAE and CED are shown what is the measure of EBF
Answer:
∠ EBF = 98°
Step-by-step explanation:
(3x - 15) and (2x + 10) are vertically opposite angles and are congruent, then
3x - 15 = 2x + 10 ( subtract 2x from both sides )
x - 15 = 10 ( add 15 to both sides )
x = 25
3x - 15 = 3(25) - 15 = 75 - 15 = 60°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ EBF is an exterior angle of the triangle , then
∠ EBF = 60° + 38° = 98°
