A parabola is defined as all points equidistant from a given directrix and focus true or false

Answers

Answer 1

False. A parabola is not defined as all points equidistant from a given directrix and focus.

A parabola is a conic section defined as the set of all points that are equidistant from a fixed point called the focus and a fixed line called the directrix. In other words, for any point on a parabola, the distance to the focus is equal to the perpendicular distance to the directrix. This property is known as the geometric definition of a parabola.

The focus and directrix are essential elements in defining a parabola, but they do not solely define it. The shape of a parabola is determined by the distance between the focus and the directrix. Varying this distance results in different sizes and orientations of parabolas.

The specific equation of a parabola incorporates the coordinates of the focus, the directrix, and a parameter called the focal length to precisely describe its form. False is the answer.

I need help ASAP find u and v

Answers

Answer:

u = 66

v = 38

Step-by-step explanation:

In a parallelogram, opposite angles are equal.  U is opposite to 66, so it is 66 degrees

In a parallelogram, corresponding angles are supplementary.  180 - 66 = 114

this means that 3v = 114.  114/3 = 38, which is what v is.

Which statement is true about the points shown on the number line? A number line from negative 8 to negative 3. Points are at negative 5.6 and negative 4.2. CLEAR CHECK −5.6<−4.2, and −5.6 is located to the left of −4.2. −5.6<−4.2, and −5.6 is located to the right of −4.2. −5.6>−4.2, and −5.6 is located to the left of −4.2. −5.6>−4.2, and −5.6 is located to the right of −4.2.

Answers

Answer:

−5.6<−4.2, and −5.6 is located to the left of −4.2

Step-by-step explanation:

Given the statements :

−5.6<−4.2, and −5.6 is located to the left of −4.2 (True) because - 5.6 located to the left of the number line and numbers are arranged from right to left in decreasing order.

−5.6<−4.2, and −5.6 is located to the right of −4.2. (Not true) only the first assertion is correct, - 5.6 < - 4.2, but 5.6 isn't located to the right of - 4.2

−5.6>−4.2, and −5.6 is located to the left of −4.2 (Not true) ; Though 5.6 is located to the left of 4 2, 5.6 is < 4.2

−5.6>−4.2, and −5.6 is located to the right of −4.2. (Not true) ; - 5.6 is < -4.2 and also located to the left of - 4.2

Answers

angle DCF = angle DCE + angle ECF

angle DCF = 75° + 54°

angle DCF = 129°

Measure of < DCF is  [tex]129^{0}[/tex].

What is an angle?

A figure which is formed by two rays or lines that shares a common endpoint is called an angle.

According to the figure

< DCE = [tex]75^{0}[/tex]

< ECF = [tex]54^{0}[/tex]

Measure of < DCF = < DCE + < ECF

=  [tex]75^{0}[/tex] +  [tex]54^{0}[/tex]

= [tex]129^{0}[/tex]

Hence, measure of < DCF is  [tex]129^{0}[/tex].

Answers

Answer:

● First part = 2×x = 2x

● Second part= 8×x = 8x

● Third part= 6×x = 6x

2x+8x+6x = 144

or, 16x= 144

or, x=144/6

F is inversely proportional to d^2. When F=9, d=4 Work out d (positive value rounded to 2 DP) when F=6

Answers

Answer:

d = 4.90

Step-by-step explanation:

Given the following data;

F = 9

d = 4

For an inversely proportional relationship, we have;

F = k/d²

Now, we would find the constant, k;

9 = k/4²

k = 9*16

k = 144

Next, to find d, when F = 6

d² = k/F

d² = 144/6

d² = 24

Taking the square root of both sides, we have;

d = 4.90

The 3 measure of central tendencies are namely;

Mean, median mode.

- Mean is defined as the average of a set of data.

- Median is the middle term of a set of data that splits that set of data into 2.

- Mode is the term that occurs most frequently in a set of data.

In this question, we want to find the movies most frequently watched.

Thus, from the definitions above earlier, it is clear that the only way to know this is using the mode.

consider a rectangular prism with length 4 and width and height d

Find an expression for the volume of the prisms in terms of d.

2. compute the volume of the prism when d=1, when d=2, and when d=1/2

Answers

Answer:

Step-by-step explanation:

The expression for the volume of the prisms in terms of d is 4d².

What is a volume?

Volume is the amount of space occupied by a three dimensional shape or object. For a rectangular prism:

Volume = length * width * height

From the diagram, length = 4, width = d, height = d. Hence:

Volume = 4 * d * d = 4d²

When d = 1: Volume = 4(1)² = 4

When d = 2: Volume = 4(2)² = 16

When d = 1/2: Volume = 4(1/2)² = 1

The expression for the volume of the prisms in terms of d is 4d².

A pair of jeans is normally priced at $56, but is currently marked down for with a 35% discount. What would replace the B in the proportion? A/B=P/100%

Answers

Answer:

$36.4

Step-by-step explanation:

Given

Cost of Jean = $56

Percent markdown = 35%

Discount = 35% of $56

Discount = 0.35 * 56

Discount = $19.6

New price = $56 - (35% of $56)

New price = $56 - 19.6

New price = $36.4

hence the price that will replace B is $36.4

A trader sold a radio set for 72.00 making a profit of 8% .Find , correct to the nearest ghana cedis ,the cost price for the radio set .

Answers

Given:

The selling price of a ratio set = 72.00

Profit percent = 8%

To find:

The cost price for the radio set.

Solution:

Let x be the cost price for the radio set.

Radio set is sold at 8% profit.

[tex]\text{Selling price}=x+\dfrac{8}{100}x[/tex]

[tex]\text{Selling price}=x+0.08x[/tex]

[tex]\text{Selling price}=1.08x[/tex]

The selling price of a ratio set is 72.00.

[tex]72=1.08x[/tex]

[tex]\dfrac{72}{1.08}=x[/tex]

[tex]x=66.666...[/tex]

[tex]x\approx 67[/tex]

Therefore, the cost price for the radio set is 67.
