y = -2(x-2) (x+8)

Step-by-step explanation:

got you bro

Answer:

y = -2x² -12x + 32.

Step-by-step explanation:

Recall that a quadratic equation in standard form is:

y = ax² + bx + c.

To rewrite the equation in standard form, you will need to FOIL and distribute the -2. This can be done by:

y = -2(x-2)(x+8)

FOIL the factored part of the equation. Ignore the '-2' for now.

y = -2 (x² +6x -16)

Now, multiply the '-2' with all of the terms:

y = -2x² -12x + 32.

This is your equation in standard form!

Step-by-step explanation:

Given values:

[tex]3x^2 + 3y^2 + 12x - 6y - 21 = 0\\5x^2 + 5y^2 - 10x + 40y - 75 = 0\\5x^2 + 5y^2 - 30x + 20y - 10 = 0\\4x^2 + 4y^2 + 16x - 8y - 308 = 0\\x^2 + y^2 -12x - 8y - 100 = 0\\2x^2 + 2y^2 - 8x + 12y - 40 = 0\\4x^2 + 4y^2 - 16x + 24y - 28 = 0\\3x^2 + 3y^2 - 18x + 12y - 81 = 0\\x^2 + y^2 - 2x + 8y -13 = 0\\x^2 + y^2 + 24x + 30y + 17 = 0\\[/tex]

Following are the concentric value:

[tex]\Rightarrow 3x^2 + 3y^2 + 12x - 6y - 21 = 0 \leftrightarrow 4x^2 + 4y^2 + 16x - 8y - 308 = 0 \\\\[/tex]

[tex]\Rightarrow 5x^2 + 5y^2 - 10x + 40y -75 = 0 \leftrightarrow x^2 + y^2 - 2x + 8y- 13 = 0\\\\[/tex]

[tex]\Rightarrow 5x^2 + 5y^2 - 30x + 20y - 10 = 0 \leftrightarrow 3x^2 + 3y^2 - 18x + 12y - 81 = 0 \\\\[/tex]

[tex]\Rightarrow 2x^2 + 2y^2 - 8x + 12y - 40 = 0 \leftrightarrow 4x^2 + 4y^2 - 16x + 24y - 28 = 0[/tex]

Answer:

(0,1/2)

Step-by-step explanation:

When X=0, Y=0.5, or 1/2

1/2=0+1/2

Answer:

(0, 1/2)

Step-by-step explanation:

y = x + 1/2

This is in slope intercept form

y = mx+b where m is the slope and b is the y intercept

The slope is 1 and the y intercept is 1/2

Answer:

[tex](x+4)^2+(y+6)^2=100[/tex]

Step-by-step explanation:

Given a circle centred at the point P(-4,-6) and passing through the point

R(2,2).

To find its equation, we follow these steps.

Step 1: Determine its radius, r using the distance formula

For point P(-4,-6) and R(2,2)

[tex]\text{Distance Formula=}\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\text{Radius=}\sqrt{(2-(-4))^2+(2-(-6))^2} \\=\sqrt{(2+4))^2+(2+6)^2}\\=\sqrt{6^2+8^2}\\=\sqrt{100}\\Radius=10[/tex]

Step 2: Determine the equation

The general form of the equation of a circle passing through point (h,k) with a radius of r is given as: [tex](x-h)^2+(y-k)^2=r^2[/tex]

Centre,(h,k)=P(-4,-6)

r=10

Therefore, the equation of the circle is:

[tex](x-(-4))^2+(y-(-6))^2=10^2\\\\(x+4)^2+(y+6)^2=100[/tex]

Answer:

[tex]sin 240^\circ = - \dfrac{\sqrt{3}}{2}[/tex]

Step-by-step explanation:

We are given that:

[tex]sin 60^\circ = \dfrac{\sqrt{3}}{2}[/tex]

We need to find

[tex]sin 240^\circ = ?[/tex]

240 is greater than 180 and lesser than 270

OR

[tex]180^\circ<240^\circ<270^\circ[/tex]

So, Angle [tex]240 ^\circ[/tex] lies in the 3rd quadrant and it is well known that value of sine in 3rd quadrant is negative.

Using the property :

[tex]sin(\pi + \theta) = -sin\theta[/tex] or

[tex]sin(180^\circ + \theta) = -sin\theta[/tex]

Here, [tex]\theta\ is\ 60^\circ[/tex].

[tex]sin 240^\circ =sin(180^\circ + 60^\circ) = -sin60^\circ\\\Rightarrow -\dfrac{\sqrt{3}}{2}[/tex]

Hence, the value

[tex]sin 240^\circ = - \dfrac{\sqrt{3}}{2}[/tex]

Answer: 1.8

Step-by-step explanation: I’m not entirely sure about this, but it probably is 1.8 because I don’t think the slant would change the volume, though I may be wrong

Answer:

1.8 cubic inches

Step-by-step explanation:

The perfectly vertical stack has a volume of 1.8 cubic inches. Therefore, another stack with the same amount would have the same volume, regardless of whether or not it is slanted.

Answer:

a) Equation of the line    [tex]y +1 = \frac{5}{6} (x - 2)[/tex]

b) Equation of the line  y + 1 = 0.833 ( x-2)

Step-by-step explanation:

Explanation:-

Given points are ( 2,-1) and (8 ,4)

Slope of the line

                       [tex]m = \frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

                      [tex]m = \frac{4- (-1) }{8-2 } = \frac{5}{6}[/tex]

Point - slope form

                     y - y₁ = m ( x - x₁)

                     y - (-1) = 5 /6 ( x-2)

                   6 ( y +1) = 5 (x -2)

a) Equation of the line    [tex]y +1 = \frac{5}{6} (x - 2)[/tex]

b) Equation of the line  y + 1 = 0.833 ( x-2)

Given question is incomplete; find the complete question with the attachment.

In the triangle NRL,

Points P, S and M are the midpoints of the sides NR, RL and LN respectively.

Sides SM = (3x - 4), NR = (9x - 20)

By the theorem of midpoints in a triangle,

SM = [tex]\frac{1}{2}\text{NR}[/tex]

(3x - 4) = [tex]\frac{1}{2}(9x-20)[/tex]

6x - 8 = 9x - 20

9x - 6x = 20 - 8

3x = 12

x = 4

Therefore, Option (A) will be the answer.

The value of x is equal t 4

Data;

The midpoint of a line is half the distance of the line.

Since the length of the line is RN and midpoint of the line is SM.

[tex]SM = \frac{1}{2} RN[/tex]

Let's substitute the values into the equation

[tex]SM = \frac{1}{2} NR\\3x - 4 = \frac{1}{2}(9x- 20)\\ 3x - 4 = \frac{1}{2} (9x - 20)\\2(3x - 4) = 9x - 20\\6x - 8 = 9x - 20\\9x-6x = 20 - 8 \\3x = 12\\\frac{3x}{3} = \frac{12}{3} \\x = 4[/tex]

The value of x is equal t 4

Option (3).

Step-by-step explanation:

Attached figure is the graph of a function,

f(x) = -[tex]\sqrt{-x}[/tex]

Since domain of any function is the set of all possible input values of the function,

Therefore, Domain of the function is,

Domain : x ≤ 0 Or (-∞, 0]

And range of the function is the set of all possible output values (y-values) of the function.

Therefore, Range of the function will be,

Range : y ≤ 0 Or (-∞, 0]

Therefore, Domain and range of this function is same.

Option (3) will be the answer.
