Answer:

Formula is: ( x - p )² + ( y - q )² = r², where p and q are coordinates of a center of a circle, and r is for radius.

Equation of a circle is:

B) (x-1)² + (y-1)² = 4

Answer:

The vertex is: (6, 8)

Step-by-step explanation:

First solve the equation for the variable y

x^2-4y-12x+68=0

Add 4y on both sides of the equation

4y=x^2-4y+4y-12x+68

4y=x^2-12x+68

Notice that now the equation has the general form of a parabola

ax^2 +bx +c

In this case

a=1\\b=-12\\c=68

Add (\frac{b}{2}) ^ 2 and subtract (\frac{b}{2}) ^ 2 on the right side of the equation

(\frac{b}{2}) ^ 2=(\frac{-12}{2}) ^ 2\\\\(\frac{b}{2}) ^ 2=(-6) ^ 2\\\\(\frac{b}{2}) ^ 2=36

4y=(x^2-12x+36)-36+68

Factor the expression that is inside the parentheses

4y=(x-6)^2+32

Divide both sides of the equality between 4

\frac{4}{4}y=\frac{1}{4}(x-6)^2+\frac{32}{4}

y=\frac{1}{4}(x-6)^2+8

For an equation of the form

y=a(x-h)^2 +k

the vertex is: (h, k)

In this case

h=6\\k =8

the vertex is: (6, 8)

What is the trigonometric ratio for sin Z ?
Schach [20]

In all right triangles, the ratio between a leg and the hypothenuse is the sine of the angle opposite to the leg.

So, in your case, we have

\sin(Z) = \dfrac{XY}{XZ}

In order to find XY, we have

XY = \sqrt{XZ^2-YZ^2} = \sqrt{1600-1024}=\sqrt{576} = 24

So, the ratio for the sine is

\sin(Z) = \dfrac{XY}{XZ} = \dfrac{24}{40} = \dfrac{3}{5}
