The raidius of the circle is r=___The equation of the circle in standard form____

Schach [20]

step 1

Find the radius of the circle

To find out the radius, calculate the distance between the center and any point that lie on the circle

(-2,3) and (-2,0)

Its a vertical distance

r=3-0=3 units

step 2

we have the radius r=3 units and the center (-2,3)

the equation of the circle is

$\begin{gathered} (x+2)^2+(y-3)^2=3^2 \\ (x+2)^2+(y-3)^2=9 \end{gathered}$

Describe the piecewise function below by evaluating the function for given values of the domain

tekilochka [14]

We have a piecewise function.
Therefore, to find the function, we must evaluate each domain separately.
We have then:

For $x \leq -2$ :
The function for this domain is:
$y = -3
$

For $-2 \ \textless \ x \leq 2$ :
The function for this domain is:
$y = mx + b
$
Where,
$b = -3

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

 m = (1 - (-7)) / (2 - (-2))$
$m = (1 + 7) / (2 + 2)

 m = 8/4

 m = 2$
Substituting:
$y = 2x - 3
$

For $x\ \textgreater \ 2$ :
The function for this domain is:
$y = 5$
