1.What are the distances from the point (x,y) to the focus of the parabola and the directrix?
Select two answers.
distance to the focus: √(x−2)2+(y+5)2
distance to the directrix: |y−6|
distance to the focus: √(x+4)2+(y−2)2
distance to the directrix: |x+6|
distance to the directrix: |y+6|
distance to the focus: √(x−2)2+(y+4)2
2. What is the correct standard form of the equation of the parabola?
Answers
Answer:
Part A)
5th and 6th Choices
Part B)
[tex]\displaystyle y=\frac{1}{4}x^2-x-4[/tex]
Step-by-step explanation:
We are given a parabola with focus at (2, -4) and the directrix given by y = -6.
Part A)
Since our directrix is an equation of y, the distance from any point (x, y) on the parabola to the directrix will simply be the absolute value of the difference of the y-values. Hence:
[tex]d_1=|y-(-6)|=|y+6|[/tex]
Again, we will use the distance formula. Let the point (x, y) be (x₂, y₂) and our focus (2, -4) be (x₁, y₁). Then by the distance formula:
[tex]d_2=\sqrt{(x-2)^2+(y-(-4))^2}=\sqrt{(x-2)^2+(y+4)^2[/tex]
Hence, our answers are the 5th and 6th choices.
Part B)
By definition, any point (x, y) on the parabola is equidistant to the focus and the directrix. Hence:
[tex]\sqrt{(x-2)^2+(y+4)^2}=|y+6|[/tex]
Square both sides. We may remove the absolute value as anything squared yields a positive. Hence:
[tex](x-2)^2+(y+4)^2=(y+6)^2[/tex]
Square:
[tex](x^2-4x+4)+(y^2+8y+16)=(y^2+12y+36)[/tex]
Rearrange:
[tex](x^2-4x+20)-(36)=(y^2-y^2)+(12y-8y)[/tex]
Combine like terms:
[tex]x^2-4x-16=4y[/tex]
Divide both sides by 4. Hence, our equation is:
[tex]\displaystyle y=\frac{1}{4}x^2-x-4[/tex]

Answers
Answer:
the domain or set of departure of a function is the set into which all of the input of the function is constrained to fall.2. The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6. It is that simple!

What equation represents the line that passes through points (1.-5) and (3 -17)?
Answers
ALL LINES CAN BE REPRESENTED IN THE FORM [tex]f(x) = ax+b[/tex].
We know that:
[tex]f(1) = -5 \implies a\cdot(1)+b = -5 \implies a+b = -5[/tex]
and
[tex]f(3) = -17 \implies a\cdot(3) +b = -17 \implies 3a+b = 17[/tex]
Observe that:
[tex]3a+b = 2a+a+b = 2a+(a+b)[/tex]
So:
[tex]2a+(a+b) =-17[/tex]
But we know that [tex]a+b = -5[/tex], so:
[tex]2a+(a+b) =-17[/tex]
[tex]2a+(-5) = -17[/tex]
[tex]2a = -12[/tex]
[tex]a = -6[/tex]
Since:
[tex]a+b = -5[/tex]
[tex](-6)+b = -5[/tex]
[tex]b = 1[/tex]
So the line is:
[tex]f(x) = 1-6x[/tex]

Describe a sequence of transformations that maps Figure A to Figure B.
A. A 270° rotation about the origin, and then a dilation of 2 with center (0,0)
B. A 270° rotation about the origin, and then an expansion of 2 with center (0,0)
C. A 90° rotation about the origin, and then an expansion of 2 with center (0,0).
D. A 90° rotation about the origin, and then a dilation of 2 with center (0,0)
Answers
This is because you always rotate clockwise when doing rotations, and if you check the top of the A shape you see it is two units wide so an expansion of 2 (2x2) would be the correct option
A sequence of transformations that maps Figure A to Figure B are: A 90° rotation about the origin, and then an expansion of 2 with center (0,0).
The correct answer is an option (C)
What is transformation?"It means changing the size and position of an object from its original position to a new position."
What is rotation?"It is a transformation that turns a figure about a fixed."
For given example,
We need to describe the transformation that maps Figure A to Figure B.
First we rotate figure A by 90° about the origin.
We can observe that the size of the figure B is larger than the figure A.
So, after rotation we expand figure A by 2 units.
Therefore, a sequence of transformations that maps Figure A to Figure B are: A 90° rotation about the origin, and then an expansion of 2 with center (0,0).
The correct answer is an option (C)

A log is 20 m long, correct to the nearest metre.
It has to be cut into fence posts which must be 90 cm long, correct
to the nearest 10 centimetres.
What is the largest number of fence posts that can possibly be cut from the log?
Answers
Answer:
222 fence posts
Step-by-step explanation:
Since the log is 20 m long, correct to the nearest metre and has to be cut into fence posts which must be 90 cm long, correct to the nearest 10 centimetres, there can be x fence posts 90 cm long.
So, we have x × 90 cm = 20 m
x × 0.9 m = 20 m
x = 20 m/0.9 m
x = 222.22
x ≅ 222 fence posts
So, the largest number of fence posts that can possibly be cut from the log is 222 fence posts.

Express x^2 +12+11 in the form (x+p)^2 +q
Answers
Answer:
Assuming you meant x² + 12x + 11, then it would be expressed as:
(x + 6)² - 25
Step-by-step explanation:
The way you wrote the expression, the second term is not multiplied by x, and you wouldn't get the answer expected. It would just be x² + 33. Presumably that was in error and the 12 is in fact just a coefficient of x, so let's work from there.
x² + 12x + 11
= x² + 12x + 36 - 25
= (x + 6)² - 25

On a map, 1 inch represents 20 miles. The distance between two towns is 6 whole number 1/5 inches. How many miles are actually between the towns?
Answers
Answer:
124 miles.
Step-by-step explanation:
From the question given above, the following data were obtained:
1 in = 20 miles
6 1/5 in =?
Next, we shall express 6 1/5 in decimal for easy calculation . This can be obtained as follow:
6 1/5 = 31 / 5
6 1/5 = 6.2 in
Finally, we shall convert 6.2 in to miles. This can be obtained as follow:
1 in = 20 miles
Therefore,
6.2 in = 6.2 in × 20 miles / 1 in
6.2 in = 124 miles
Thus, 6 1/5 in is equivalent to 124 miles.
Therefore, there are 124 miles between the two towns.
