derive the equation of a parabola with a focus of (-7,5) and a directrix of y=-11
I need help with this question

Answers

Answer:

The equation of the parabola is;

(y + 11)^2/120 = (x + 7)^2 + (y-5)^2

Step-by-step explanation:

Here, we are given the focus (-7,5) and the directix y = -11

We proceed to find the equation of the parabola

That would be in the form;

(y- mx - b)^2 /m^2 + 1 = (x- h)^2 + (y-k)^2

Let’s write the directix in the form y = mx + b

This shows that m = 0 and b = -11

Also h = -7 and k = 5

So let’s substitute;

(y + 11)^2 /(-11^2 + 1) = (x+7)^2 + (y-5)^2

= (y + 11)^2/120 = (x + 7)^2 + (y-5)^2

Lisa takes a taxi uptown, and the fare is $12.78. She wants to give the driver a 10% tip.
How much would the tip be?
O $1.28
$5.94
$14:06
$18.72

Answers

Answer:14:06

Step-by-step explanation:

Because because 10 percent of 12.78 is 1.28 then 1.28 + 12.78 = 14.06 so 14.06 is your answer

The vertices of a figure are FC -9,- 9),G-3, -6),H(-3,-9). Find the coordinates of the image after a dilation with a scale factor of 2 3 and then a translation 6 units up.​

Answers

Transformation involves changing the size and position of a figure.

The new coordinates of the figure is:

[tex]\mathbf{F" = (-6,0)}[/tex]

[tex]\mathbf{G" = (2,2)}[/tex]

[tex]\mathbf{H" = (-2,0)}[/tex]

The coordinates are given as:

[tex]\mathbf{F = (-9,-9)}[/tex]

[tex]\mathbf{G = (3,-6)}[/tex]

[tex]\mathbf{H = (-3,-9)}[/tex]

When the figure is dilated by 2/3, the new coordinates are:'

[tex]\mathbf{F' =\frac 23 \times (-9,-9) = (-6,-6)}[/tex]

[tex]\mathbf{G' =\frac 23 \times (3,-6) = (2,-4)}[/tex]

[tex]\mathbf{H' =\frac 23 \times (-3,-9) = (-2,-6)}[/tex]

When the figure is further translated up by 6 units, the new coordinates are:

[tex]\mathbf{F" = (-6,-6 + 6) = (-6,0)}[/tex]

[tex]\mathbf{G" = (2,-4 + 6) = (2,2)}[/tex]

[tex]\mathbf{H" = (-2,-6 + 6) = (-2,0)}[/tex]

Hence, the new coordinates are:

[tex]\mathbf{F" = (-6,0)}[/tex]

[tex]\mathbf{G" = (2,2)}[/tex]

[tex]\mathbf{H" = (-2,0)}[/tex]

How do you know if a set of information shows a proportional relationship? Select ALL that apply.

Answers

Answer:

(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .") This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

what ordered pair would describe each intersection?
y=8-X and y=5X-40​

Answers

Answer:

(8, 0 )

Step-by-step explanation:

Given the 2 equations

y = 8 - x → (1)

y = 5x - 40 → (2)

Substitute y = 5x - 40 into (1)

5x - 40 = 8 - x ( add x to both sides )

6x - 40 = 8 ( add 8 to both sides )

6x = 48 ( divide both sides by 6 )

x = 8

Substitute x = 8 into either of the 2 equations and solve for y

Substituting into (1)

y = 8 - 8 = 0

Solution is (8, 0 )

Find the equation of the line by given two points (-5, -2) and (1, 5). Slope
Intercept Form: y = mx +b, m is a slope and b is y value of the y-intercept Slope
formula: m = (y2 - y1)/(x2 - x1)

Answers

Answer:

The equation of the line is 6y = 7x + 23

Step-by-step explanation:

We begin by calculating the slope of the line;

mathematically, the slope is given by;

m = (y2-y1)/(x2-x1)

That would be;

m= (5-(-2))/(1-(-5))

m = 7/6

So the equation becomes;

y = 7/6x + b

We below need to get the value of the y-intercept b

We get this by making a substitution for any of the two points

Let’s say we make the substitution for (-5,-2) in which case y = -2 and x = -5

Thus, we have

-2 = 7/6(-5) + b

-2 = -35/6 + b

b = -2 + 35/6

b = (-12+ 35)/6 = 23/6

So we have;

y = 7/6x + 23/6

let’s multiply through by 6

6y = 7x + 23

Surveyors wished to know the distance across a lake between A and B. They measured the distance from B to C as 100 m and the angle from C to A to be 55°. Knowing that the angle between CB and BA was 90°, they used trig to solve for the distance. Show how it was done

Answers

Answer:

AB ≈ 70m

Step-by-step explanation:

Check the attachment for the diagram.

You can see from the diagram that it is a right angled triangle with opposite side AB and adjacent side BC. Using SOH, CAH, TOA trig identity to get the length of AB. According to TOA;

tan 35° = opposite/adjacent

tan 35° = AB/BC

tan 35° = AB/100

AB = 100tan35°

AB = 100 * 0.7002

AB = 70.02m

Hence the distance across a lake between A and B is approximately 70m
