Given:

Focus of the parabola = [tex]\left(-\dfrac{1}{4},-\dfrac{2}{3}\right)[/tex]

Directrix of the parabola is [tex]y=\dfrac{3}{4}[/tex].

To find:

The equation of the parabola.

Solution:

The equation of the parabola is:

[tex](x-h)^2=4p(y-k)[/tex]             ...(i)

Where, (h,k) is vertex, (h,k+p) is focus and [tex]y=k-p[/tex] is the directrix.

It is given that the focus of the parabola is at [tex][/tex].

[tex](h,k+p)=\left(-\dfrac{1}{4},-\dfrac{2}{3}\right)[/tex]

On comparing both sides, we get

[tex]h=-\dfrac{1}{4}[/tex]

[tex]k+p=-\dfrac{2}{3}[/tex]            ...(ii)

Directrix of the parabola is [tex]y=\dfrac{3}{4}[/tex]. So,

[tex]k-p=\dfrac{3}{4}[/tex]             ...(iii)

Adding (ii) and (iii), we get

[tex]2k=-\dfrac{2}{3}+\dfrac{3}{4}[/tex]

[tex]2k=\dfrac{-8+9}{12}[/tex]

[tex]k=\dfrac{1}{12\times 2}[/tex]

[tex]k=\dfrac{1}{24}[/tex]

Putting [tex]k=\dfrac{1}{24}[/tex] in (ii), we get

[tex]\dfrac{1}{24}+p=-\dfrac{2}{3}[/tex]

[tex]p=-\dfrac{2}{3}-\dfrac{1}{24}[/tex]

[tex]p=\dfrac{-16-1}{24}[/tex]

[tex]p=\dfrac{-17}{24}[/tex]

Putting [tex]h=-\dfrac{1}{4},k=\dfrac{1}{24}, p=-\dfrac{17}{24}[/tex] in (i), we get

[tex]\left(x-(-\dfrac{1}{4})\right)^2=4\left(-\dfrac{17}{24}\right)\left(y-\dfrac{1}{24}\right)[/tex]

[tex]\left(x+\dfrac{1}{4}\right)^2=-\dfrac{17}{6}\left(y-\dfrac{1}{24}\right)[/tex]

[tex]x^2+2(x)(\dfrac{1}{4})+(\dfrac{1}{4})^2=-\dfrac{17}{6}\left(y-\dfrac{1}{24}\right)[/tex]

[tex]-\dfrac{6}{17}\left(x^2+\dfrac{1}{2}x+\dfrac{1}{16}\right)=y-\dfrac{1}{24}[/tex]

On further simplification, we get

[tex]-\dfrac{6}{17}(x^2)-\dfrac{6}{17}(\dfrac{1}{2}x)-\dfrac{6}{17}(\dfrac{1}{16})=y-\dfrac{1}{24}[/tex]

[tex]-\dfrac{6}{17}x^2-\dfrac{3}{17}x-\dfrac{3}{136}+\dfrac{1}{24}=y[/tex]

[tex]-\dfrac{6}{17}x^2-\dfrac{3}{17}x+\dfrac{-9+17}{408}=y[/tex]

[tex]-\dfrac{6}{17}x^2-\dfrac{3}{17}x+\dfrac{8}{408}=y[/tex]

[tex]-\dfrac{6}{17}x^2-\dfrac{3}{17}x+\dfrac{1}{51}=y[/tex]

Therefore, the equation of the parabola is [tex]y=-\dfrac{6}{17}x^2-\dfrac{3}{17}x+\dfrac{1}{51}[/tex]. Hence, the correct option is C.

Answer:

positive slope

Step-by-step explanation:

when a graph is sloping to the right it means it has a positive . the gradient of this straight is positive .

gradient of the line is greater than 0

The slope of the line is m = 2

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

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

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P ( 1 , 3 )

Let the second point be Q ( 0 , 1 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 3 - 1 ) / ( 1 - 0 )

m = 2

Therefore , the value of m is 2

Hence , the slope is 2

[tex]\sin(105) = \frac{\sqrt 2 + \sqrt 6}{4}[/tex]

Step-by-step explanation:

Given

[tex]\sin(105^o)[/tex]

Required

Solve

Using sine rule, we have:

[tex]\sin(A + B) = \sin(A)\cos(B) + \sin(B)\cos(A)[/tex]

This gives:

[tex]\sin(105^o) = \sin(60 + 45)[/tex]

So, we have:

[tex]\sin(60 + 45) = \sin(60)\cos(45) + \sin(45)\cos(60)[/tex]

In radical forms, we have:

[tex]\sin(60 + 45) = \frac{\sqrt 3}{2} * \frac{\sqrt 2}{2} + \frac{\sqrt 2}{2} * \frac{1}{2}[/tex]

[tex]\sin(60 + 45) = \frac{\sqrt 6}{4} + \frac{\sqrt 2}{4}[/tex]

Take LCM

[tex]\sin(60 + 45) = \frac{\sqrt 6 + \sqrt 2}{4}[/tex]

Rewrite as:

[tex]\sin(60 + 45) = \frac{\sqrt 2 + \sqrt 6}{4}[/tex]

Hence:

[tex]\sin(105) = \frac{\sqrt 2 + \sqrt 6}{4}[/tex]

Step-by-step explanation:

7 x 3/10 = 21/10

Temperature at midnight = -1°C

Temperature at 7.00 am = 21/10°C -1°C = 11/10°C

Answer:

1.1°C

Step-by-step explanation:

Assuming we are starting at midnight, we know that at midnight it is -1°C. We want to find the temperature at 7:00 AM. Or 7 hours later than midnight. The question says that every hour the temperature rises by 3/10°C. In 7 hours, we need to multiply 3/10*7=21/10=2.1 °C. So, it rises by 2.1 °C. Next add that to the -1 from midnight. Do 2.1+-1=1.1 °C.

Answer:

Step-by-step explanation:

3. sin^2A + cos^2A = 1  (formula )

1 + tan^2 theta = sec^2 theta  (derived from the formula sec^2 theta - tan^2 theta )

b.2x = 12 (by comparing the corresponding element)

x = 12/2

x = 6

3y = 12 (by comparing the corresponding element)

y = 12/3

y = 4

mean = sum of data / no of data

4+7+5+9+11+6 / 6

42 / 6

7

mean = 7

to find median arrange the data from ascending to descending order (from smallest to biggest)

data = 3,4,6,8,10,12

median = (N +1)/2   (N means no of data )

=6 + 1/2

=7/2

=3.5

=3 th term + 4 th term /2

=6 +8 / 2

=14/2

=7 median = 7

to find value of theta

90° + 50° + theta = 180° (sum of interior angles of a triangle)

140° + theta = 180°

theta = 180° - 140°

theta = 40°

therefore theta = 40°

The mode is the highest frequency data among the given data set is 2.

The value that appears most frequently in a data set is called the mode. One mode, several modes, or none at all may be present in a set of data.

Mode is the highest frequency of any number among data

For example 2,3,5,5,6,5,9,8,5,1

Here mode will be 5 because it has a frequency of 4 remaining all have a lower frequency than 5.

Given the data set is

2, 8, 16, 4, 12, 9, 2

2 has frequency = 2

And remaining all have a frequency as 1

Since 2 has the highest frequency so it will be mode.

Given:

The equation of a line is:

[tex]y=5x+1[/tex]

A line is parallel to the given line and passes through the point (3,-4).

To find:

The equation of the line in the slope intercept form.

Solution:

The slope intercept form of a line is:

[tex]y=mx+b[/tex]             ...(i)

Where, m is the slope and b is the y-intercept of the line.

We have,

[tex]y=5x+1[/tex]                ...(ii)

On comparing (i) and (ii), we get

[tex]m=5[/tex]

Slope of the given line is 5.

We know that the slopes of parallel lines are equal. So, the slope of the required line is 5.

The required line passes through the point (3,-4) with slope 5. So, the equation of the required line is:

[tex]y-y_1=m(x-x_1)[/tex]

[tex]y-(-4)=5(x-3)[/tex]

[tex]y+4=5(x)+5(-3)[/tex]

[tex]y+4=5x-15[/tex]

Subtracting 4 from both sides, we get

[tex]y+4-4=5x-15-4[/tex]

[tex]y=5x-19[/tex]

Therefore, the equation of the required line is [tex]y=5x-19[/tex].

Answer:

The given relation is presented as follows;

[tex]\dfrac{1}{a} + \dfrac{1}{b} +\dfrac{1}{c} = \dfrac{1}{a + b + c}[/tex]

Where 'a', 'b', and 'c' are member of real numbers, we have;

a⁹, b⁹, and c⁹ are also member of real numbers

When a⁹ = x, b⁹ = y, and c⁹ = z

By the above relationship, we have;

[tex]\dfrac{1}{x} + \dfrac{1}{y} +\dfrac{1}{z} = \dfrac{1}{x + y + z}[/tex]

Substituting x = a⁹, y = b⁹, and z = c⁹, we get;

[tex]\dfrac{1}{a^9} + \dfrac{1}{b^9} +\dfrac{1}{c^9} = \dfrac{1}{a^9 + b^9 + c^9}[/tex]
