Write the equation of a circle with a center at (-1,2) and a radius of 7
Sever21 [200]

Answer:

(x+1)^2+(y-2)^2=49

Step-by-step explanation:

The standard form for the equation of a circle is (x-h)^2+(y-k)^2=r^2 where  r  is the radius, and the center is (h, k).

(h, k) = (-1, 2),  r = 7

(x-(-1))^2+(y-2)^2=7^2\\\\(x+1)^2+(y-2)^2=49

The vertices of ABC are A(-2, 2), B(6,2), and CO, 8). The perimeter of ABC?
Alexxx [7]

Answer:

Perimeter = 22.809836694575                              

Step-by-step explanation:

A(-2, 2)  ;  B(6,2)  ;  C(0, 8)

AB=\sqrt{\left( 6--2\right)^{2}  +\left(2-2 \right)^{2}  } =\sqrt{64} =8

AC=\sqrt{\left( 0--2\right)^{2}  +\left(8-2 \right)^{2}  } =\sqrt{40} =2\sqrt{10}

BC=\sqrt{\left( 0-6\right)^{2}  +\left(8-2 \right)^{2}  } =\sqrt{72} =6\sqrt{2}

Then

The perimeter of ΔABC = AB + BC + AC

                                       =8+6\sqrt{2} +2\sqrt{10}

                                       = 22.809836694575
