The diameter of a circle has length 12. The center is at*(-5, 2). Give the equation
labwork [276]

Answer:

Equation of the circle is : x^{2} + 10x + y^{2} -4y -7 =0

Step-by-step explanation:

Let us consider the image attached in the answer area.

The center<em> O</em> has the co-ordinates i.e. <em>(-5,2)</em> and the diameter given is <em>12 units</em>.

We know that radius is half of diameter.

\text{Radius = }\dfrac{\text{Diameter}}{2}

\text{Radius = }\dfrac{12}{2}\\\Rightarrow \text{Radius = 6units}

The equation for circle given the center and radius, can be represented as:

(x-a)^{2}+ (y-b)^{2} = r^{2}

Where <em>(a,b)</em> is the co-ordinate of center and <em>r</em> is the radius.

Let us consider the following formula:

(p+q)^2 = p^{2}+ q^{2} +2pq\\(p-q)^2 = p^{2}+ q^{2} -2pq

(x-(-5))^{2}+ (y-2)^{2} = 6^{2}\\\Rightarrow (x+5)^{2}+ (y-2)^{2} = 36\\\Rightarrow x^{2} + 25 + 10x +y^{2} + 4-4y=36\\\Rightarrow x^{2} + 10x +y^{2} -4y-7=0

Hence, Equation of the circle is : x^{2} + 10x + y^{2} -4y -7 =0

Which graph represents the inequality x ≤ –2 or x ≥ 0?
Vikki [24]

For this case we have the following expressions:

x \leq-2\\x \geq0

So:

x \leq-2 Indicates all values less than or equal to -2.

That is, from -∞ to -2.

x \geq0 Indicates all values greater than or equal to 0.

That is, from 0 to ∞.

The "or" means that they do not intersect. So, the correct graph is option A.

Answer:

Option A

Alekssandra [29.7K]
79\frac{79-100}{1} = \frac{-21}{1} = \boxed {\frac{-21\times x}{1\times x}= \frac{-21}{1} = \frac{-42}{2}= \frac{-63}{3} =...  and~so ~on}
