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

Mathematics
1 answer:
Schach [20]1 year ago
3 0

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}

What is the equation of the line that passes through the point (-6,-6)and has a slope of -\frac{1}{3}− ?
Gnesinka [82]

9514 1404 393

Answer:

  y +6 = (-1/3)(x +6)

Step-by-step explanation:

Given a point and a slope, it is appropriate to use the point-slope form to represent the equation:

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

For your point and slope, the equation is ...

  y -(-6) = -1/3(x -(-6))

  y +6 = -1/3(x +6)

__

Of course, this can be rearranged to whatever form you need.

  y = -1/3x -8 . . . . slope-intercept form

  x +3y = -24 . . . . standard form

The point p (3,4) is the midpoint of the join of A (7,8) and B find tge coordinates of B
Shalnov [3]

Answer:

B(-1, 0)

Step-by-step explanation:

coordinates of midpoint p(x,y) are calculated as

x= \frac{x_1+x_2}{2}  ---------- (1)

y= \frac{y_1+ y_2}{2}  -----------(2)

Here (x_1, y_1) = (7, 8) and (x_2, y_2) \ is \ unkwon

<u>Using equation (1)</u>

<u />3=\frac{7+x_2}{2} \\x_2=-1<u />

<u>Using equation (2)</u>

<u />4=\frac{8+y_2}{2} \\y_2=0<u />
