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:

[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 and 2/3 gallons of water.

Step-by-step explanation:

5/9*3=15/9

15/9=1 and 6/9

6/9 simplified is 2/3

Answer: 1 and 2/3 gallons of water

Based on the information given, the amount of water used will be 1 2/3 gallons.

From the information given, it was stated that Ivan watered 3 plants and that every plant got 5/9 gallons of water.

Therefore, the amount of water that'll be used for all will be:

= 5/9 × 3

= 15/9

= 1 2/3.

In conclusion, the correct option is 1 2/3 gallons.

Answer:

Angle measures, size, shape, position of center of rotation.

Step-by-step explanation:

Rotation is a rigid motion, meaning the angle measures, size, and shape are preserved. Also, since we are rotating around the center, the center would stay the same. So the answer is angle measures, size, shape, position of center of rotation.

When a shape is rotated, it must be rotated through a center.

Angle measures , the size , the shape , and the position of center of rotation do not change after rotation

Rotation is a rigid transformation.

This means that, rotation does not change the angle measure, the side lengths and the shape of the shape that is being rotated.

Except the center of rotation is changed to perform another rotation, the rotation does  not change the center of rotation.

Hence, all except orientation remain unchanged after a rotation.

Answer:

8 large candles

Step-by-step explanation:

If all the candles were large candles,

Amount received

= 20( $27.98)

= $559.60

Difference in amount received

= $559.60 -$355.60

= $204

Difference in the cost of a small candle to a large candle

= $27.98 -$10.98

= $17

Number of small candles

= $204 ÷$17

= 12

Thus, number of large candles

= 20 -12

= 8

Let's check!

Amount received

= 8( $27.98) +12( $10.98)

= $355.60 ✓

Answer:

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.

Answer:

C.) The range and domain of the graph are the same.

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]

Hope this helps <3

P.S. please mark brainliest!

It is found that liquid measuring cup has less liquid than the cup.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.

We are given that 16 liquid measuring cups in a gallon. If a gallon contains 3,785 milliliters,

Therefore, we need to divide the 3,785 milliliters, with the liquid measuring cups

So, 3785/16=236.5625

Thus, That would be less.

  x=4 and x=-4

Step-by-step explanation:

We assume you intend ...

  y = (x^2 +5x +6)/(x^2 -16)

There will generally be points of discontinuity where the denominator is zero. Sometimes a denominator factor will be cancelled by a numerator factor, but the "hole" remains and there is still a discontinuity there.

Here, the denominator factors as the difference of squares:

  x^2 -16 = (x -4)(x +4)

There will be discontinuities where these factors are zero, at x=4 and x=-4.

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!
