Derive the equation of the parabola with a focus at (−2, 4) and a directrix of y = 6. Put the equation in standard form.
f(x) = one fourthx2 − x + 4
f(x) = −one fourthx2 − x + 4
f(x) = one fourthx2 − x + 5
f(x) = −one fourthx2 − x + 5
Answers
Answer:
B
Step-by-step explanation:
From any point (x, y) on the parabola the focus and directrix are equidistant.
Using the distance formula
[tex]\sqrt{(x+2)^2+(y-4)^2}[/tex] = | y - 6 |
Squaring both sides
(x + 2)² + (y - 4)² = (y - 6)² ← distributing
x² + 4x + 4 + y² - 8y + 16 = y² - 12y + 36 ( subtract y² - 12y + 36 from both sides )
x² + 4x + 4 + 4y - 20 = 0 ( subtract x² + 4x + 4 from both sides )
4y - 20 = - x² - 4x - 4 ( add 20 to both sides )
4y = - x² - 4x + 16 ( divide through by 4 )
y = - [tex]\frac{1}{4}[/tex] x² - x + 4, that is
f(x) = - [tex]\frac{1}{4}[/tex] x² - x + 4 → B
Answer:
Option B
Step-by-step explanation:
Given that a parabola has a focus at (−2, 4) and a directrix of y = 6.
We have to find the equation of the parabola in std form
We know that a parabola is a conic section in which all points are equidistant from the focus and vertex.
Let (x,y) be any point on the parabola
Distance of (x,y) from the focus =[tex]\sqrt{(x+2)^2+(y-4)^2}[/tex] ...i
Distance of (x,y) from directrix = difference in y coordinate = [tex]|y[-6|[/tex]...ii
Since i = ii, square and equate both
[tex](x+2)^2+(y-4)^2=(y-6)^2\\x^2+4x+4 -8y+16 = -12y+36\\4y=-x^2-4x+16\\y = \frac{-1}{4} d^2-x+4[/tex]
Hence option B is right.

Answer: I think the answer is -x + y.
Step-by-step explanation:I think this is the answer because you first start off by distributing all the variables inside the parenthesis by the negative sign which would give you -x+2y-y. After that, you would have to subtract 2y-y because they share the same variable and you must have a SIMPLIFIED ANSWER. So with that said, your overall answer should be -x+y.

HELP! Consider the function represented by the graph. On a coordinate plane, a straight line with a negative slope begins on the y-axis at (0, 9) and exits the plane at (8, 1). What is the domain of this function?
Answers
Answer:
{ x | x ≥ 0 }
Step-by-step explanation:
Given,
There is a straight line started from (0, 9) and passes through (8, 1),
∵ In the coordinate plan, the values of x are arranged in increasing order to the right side of the y-axis,
Thus, the line is defined for all real values of x greater than 0,
Hence, Domain of the line = All real numbers greater than equal to 0,
i.e. { x | x ≥ 0 }

Step-by-step explanation:
following the accepted steps you would first reflect the graph across the y axis due to the negative sign within the function, then you would reflect the result across the x axis due to the negative sign outside of the function.
In practice however you only need to reflect across the x axis as -(-x)^2 simplifies to -x^2
1. Two angles are supplements. The larger is 10 more than 4 times the smaller. Find both angles,
2. Two angles are supplements. They're equal in measure. Find both angles.
3. The supplement of an angle is three times the complement of the angle. Find the angle.
4. The supplement of an angle is 12 less than twice the angle. Find both angles.
Answers
Step-by-step explanation:
Supplementary angles equal 180°
1. Let the two angles be x and y
then y = 4x + 10
x + y = 180
x + (4x + 10) = 180
5x + 10 = 180
5x = 180 - 10
5x = 170
x = 170 / 5
x = 34
x = 34y = 146
2. if the two angles are equal then divide 180 by 2 to get 90
3. 180 - x = 3(90 - x)
180 - x = 270 - 3x
2x = 90
x = 45
4. 180 - x = 2x - 12
180 - 12 = 2x + x
168 = 3x
x = 56
3 lines are shown. A line with points T, R, W intersects with a line with points S, R, V at point R. Another line extends from point R to point U in between angle V R W. Which pair of angles are vertical angles? AngleWRU and AngleSRT AngleWRS and AngleVRT AngleVRU and AngleTRS AngleVRT and AngleSRT
Answers
Answer:
The vertical angles are ∠ WRS and ∠ VRT ⇒ 2nd answer
Step-by-step explanation:
* Lets explain the meaning of the vertical angles
- Vertical angles are the angles opposite to each other when two lines
are intersected
- The vertical angle are equal in measures
- Look to attached figure which represents the lines
∵ Line TW intersects line SV at R
∴ ∠ WRV and ∠ SRT are vertical angle
∴ ∠ WRS and ∠ VRT are vertical angle
∵ RU is between the rays of angle VRW
∴ RU intersects the lines TW and SV at R
∴ No vertical angles between RU and the other two lines because
it intersects them its endpoint R
* Now lets look to the answer to chose the right one
- ∠ WRU and ∠ SRT are not vertical angles
- ∠ WRS and ∠ VRT are vertical angles
- ∠ VRU and ∠ TRS are not vertical angles
- ∠ VRT and ∠ SRT are not vertical angles
The pair of angles that are vertical angles is: ∠WRS and ∠VRT.
What are Vertical Angles?When two straight lines intersect each other at a point, the opposite angles that are vertical to each other are called vertical angles.
∠WRS and ∠VRT are vertically opposite each other.
Therefore, the pair of angles that are vertical angles is: ∠WRS and ∠VRT.

Answer:
Given: The total cost of renting a car is determined by the number of days a car is rented, at $75 per day, and the number of miles it is driven, at $0.50 per mile. The company uses the expression [tex]75x +0.50y[/tex] to evaluate the total cost of renting a car.
To check: We need to check what does the variable x represent.
Here, the company uses the expression [tex]75x +0.50y[/tex] to evaluate the total cost of renting a car.
Here 75 represents the rent per day, and 0.50 represents the cost per mile.
As, x is multiplied by 75. So, the variable x represents the number of day one has taken the car.

Answers
Answer:
x = 8
Step-by-step explanation:
Simplifying
9x + -25 = 5x + 7
Reorder the terms:
-25 + 9x = 5x + 7
Reorder the terms:
-25 + 9x = 7 + 5x
Solving
-25 + 9x = 7 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
-25 + 9x + -5x = 7 + 5x + -5x
Combine like terms: 9x + -5x = 4x
-25 + 4x = 7 + 5x + -5x
Combine like terms: 5x + -5x = 0
-25 + 4x = 7 + 0
-25 + 4x = 7
Add '25' to each side of the equation.
-25 + 25 + 4x = 7 + 25
Combine like terms: -25 + 25 = 0
0 + 4x = 7 + 25
4x = 7 + 25
Combine like terms: 7 + 25 = 32
4x = 32
Divide each side by '4'.

If the estimated answer is [tex]800000[/tex] that means that we are looking at a multiplication in the "order of" [tex]8*10^5[/tex]
You need to look at the "orders of magnitude" of the things you're multiplying. In the first case, we have [tex]8146*12[/tex] that would be "of the order of" [tex]8*10^3[/tex] times [tex]10^1[/tex]. So the whole multiplication would "of the order of" [tex]8*10^4[/tex] or near [tex]80000[/tex]
