What is the coordinates of the focus for the following parabola -8(x-5)=(y+1)^2
By definition of the focus of a parabola, the coordinates of the focus of the parabola - 8 · (x - 5) = (y + 1)² are represented by the point F(x, y) = (3, - 1). (Correct choice: A)
How to locate the focus of a parabola
The standard equation of the parabola with an horizontal axis of symmetry is presented below:
[tex]x - h = \frac{1}{4\cdot p}\cdot (y - k)^{2}[/tex] (1)
Where:
h, k - Vertex of the parabola.p - Distance between the vertex and the focus.The coordinates of the focus is described by the following expression:
F(x, y) = (h + p, k)
If we know that h = 5, k = - 1 and p = - 2, then the coordinates of the focus are:
F(x, y) = (5 - 2, - 1)
F(x, y) = (3, - 1)
By definition of the focus of a parabola, the coordinates of the focus of the parabola - 8 · (x - 5) = (y + 1)² are represented by the point F(x, y) = (3, - 1). (Correct choice: A)

Find the value of x. -1x + 72 = -3x + 84
Answer:
x=6
Step-by-step explanation:
First, add x to each side.
72=-2x+84
Subtract 84 from each side
-12=-2x
Dive each side by -2
6=x
Answer:
x=6
Step-by-step explanation:
-1x+72=-3x+84
+3x on both sides
2x+72=84
subtract 72 on both sides
2x=12
divide by 2 on both sides
x=6
find the angles of x and y

or,180-34
or x=146
Now,
or, y=146
or,18=146
or146-18
or, y=128
there is x is 34 and its all side angle is 180 degree So put x =180 and then put x value is 34 =180 and there is no values in front of 34 so there will be + and if +so in another side it will be - and then after put 180-34=146

Step-by-step explanation:
complete the square f(x)=x^2-12x-4
Answer:
Solve for x over the real numbers:
x^2 - 12 x - 4 = 0
Add 4 to both sides:
x^2 - 12 x = 4
Add 36 to both sides:
x^2 - 12 x + 36 = 40
Write the left hand side as a square:
(x - 6)^2 = 40
Take the square root of both sides:
x - 6 = 2 sqrt(10) or x - 6 = -2 sqrt(10)
Add 6 to both sides:
x = 6 + 2 sqrt(10) or x - 6 = -2 sqrt(10)
Add 6 to both sides:
Answer: |
| x = 6 + 2 sqrt(10) or x = 6 - 2 sqrt(10)

Which survey question is biased?
A. "Should the President of the United States serve a six-year term?"
B. "Which meal-breakfast, lunch, or dinner-is your favorite meal of the day?"
C. “During which month do you prefer to go on vacation?"
D. “Do you prefer white bread or healthy, whole-wheat bread?”
Answer:
A.
Step-by-step explanation:
It was trick question because they all are opinionated, but the first one should be an easy yes or no question. However, if you do not like the president then you would say no because of bias. The rest are supposed to be "biased" because they are asking what you prefer.
"Should the President of the United States serve a six-year term?" is question is biased
What is Survey bias?Survey bias is a "systematic error introduced into sampling or testing by selecting or encouraging one outcome or answer over others." Due to this "encouragement" for a particular result, surveys may be biassed and only provide one type of consumer perspective.
For first, It presumes that the responder supports the idea that the President should hold office for a six-year term, which may not apply to all respondents.
However, out of bias, you would say "no" if you didn't like the president. The others are supposedly "biassed" since they inquire about your preferences.
Thus, the biased question is Should the President of the United States serve a six-year term?.

See if the two sides are congruent. If they are, state how you know.
Answer:
ASA
Step-by-step explanation:
The ASA (angle side angle) identity states that if 2 triangles share 2 angles and one side in between the angles with each other, they are congruent. Since that is the case here, it is the answer.
Answer:
ASA
Step-by-step explanation:
When you have 2 angles and a side, look and see if the side is between the 2 angles. What that means is that both angles share the one side.
If that happens, then the solution to congruence is ASA. I'd be very careful about using SSA. There are exceptions and you should not choose it if you have a choice. Sometimes it works and sometimes it does not.
find the surface area.
Answer:
solution given:
For triangle
side1=9ft
side2=10ft
base[b]=11ft
height[h]=7.7ft
and for rectangle
length [l]=3ft
wide [w]=9ft
Now
total surface area=lateral surface area +2curved surface area
=perimeter of triangle×length +2area of triangle
=(9+10+11)×3+2×1/2×2(½×b*h)
=90+11×7.7
=174.7

Biologists studying wildlife in the state parks want to estimate the average weight of chipmunks. They measured the weights of 5 chipmunks from each of 10 parks. The mean of the data was 91 grams, and the median was 87 grams
Answer:
The average weight of the chipmunks is 91 grams
Step-by-step explanation:
The mean of a dataset gives the average which is obtained by taking the sun of each data value and dividing by the number of samples. The median however requires the arrangement of data in terms of size ze (ascending) and taking the mid value (value which falls in the 50% mark). For the data above, the most appropriate measure of the average is the mean. Hence, the prediction which matches the data is ; The average weight of the chipmunks is 91 grams.
Based on the data that the Biologists found out, the prediction that best matches the data is The average weight of the chipmunks is 91 grams.
What does the data say?The data shows the weights of the five chipmunks that were recorded and the mean of these weights was 91 grams.
The mean of a dataset is the same as its average which means that the average weight found from the chipmunks was 91 grams.
In conclusion, option D is correct.
Options for this question are:
About one-half of the chipmunks weigh more than 91 grams
The average weight of the chipmunks is 87 grams.
About one-half of the chipmunks weigh more than 87 grams
The average weight of the chipmunks is 91 grams

You and three of your friends buy tickets for a concert so that you sit together in the same row. Write an expression using factorials that could be used to find the probability that you will get the seat on the far left.
Answer:
[tex]Pr = \frac{1}{4}[/tex]
Step-by-step explanation:
Given
[tex]n = 4[/tex]
Required
Probability that you seat on the far left
First, we calculate the total possible seat arrangements.
This is calculated using:
[tex]Total =n![/tex]
[tex]Total =4![/tex]
[tex]Total =4*3*2*1[/tex]
[tex]Total =24[/tex]
Next, the possible seat arrangements if you seat at the far left.
This implies that you can only seat 1 spot while your friends (3) can seat on any of the remaining 3 seats.
i.e.
[tex]You \to 1[/tex]
[tex]Friend\ 1,2,3 \to 3,2,1[/tex]
The number of arrangement is:
[tex]Arrangement = 1 * 3 *2 *1[/tex]
[tex]Arrangement = 6[/tex]
The required probability is:
[tex]Pr = \frac{Arrangement}{Total}[/tex]
[tex]Pr = \frac{6}{24}[/tex]
Simplify
[tex]Pr = \frac{1}{4}[/tex]
