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

so

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

Its a vertical distance

so

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}

Fone the slope of a line that is perpendicular x = -12
Vinvika [58]

Answer:

m [slope] = 1/12

Step-by-step explanation:

If a line is perpendicular (90 degrees, forms a right angle) to another, the slope of the line must be an opposite reciprocal of the other. The opposite reciprocal of m is -1/m.

An opposite reciprocal is created by flipping the numerator and denominator, and making it negative.

Therefore, if m is -12 it's opposite reciprocal is -1/-12 = <u>1/12</u>.

Write a linear function f with f(−10)=4 and f(−2)=4. f(x)=
ZanzabumX [31]

Answer:

f(x) = 4

Step-by-step explanation:

Let us assume that the linear function f(x) = ax + b

Here, we have to find the value of a and b to know the function.

Given that f(-10) = 4 and f(-2) = 4

So, -10a + b = 4 ....... (1) and

-2a + b = 4 .......... (2)

From equations (1) and (2) we get a = 0 and b = 4.

So, the linear function is f(x) = 4. (Answer)
