Find the coordinates of the endpoint A given B (-3,5) is the midpoint of AC and C (1,-2)

WARRIOR [948]

coordinates of endpoint A are (-7,12)

Step-by-step explanation:

We are given midpoint B (x,y) =(-3,5)

One endpoint C (x₂,y₂)= (1,-2)

We need to find other endpoint A (x₁,y₁).

The formula to find midpoint is:

$x=\frac{x_{1}+x_{2}}{2}\\y=\frac{y_{1}+y_{2}}{2}$

We can find the coordinates of endpoint A using these formula.

We have x=-3, x₁=? and x₂= 1

Putting values and finding x₁

$x=\frac{x_{1}+x_{2}}{2}\\-3=\frac{x_{1}+1}{2}\\-6=x_{1}+1\\-6-1=x_{1}\\x_{1}=-7$

Now, y=5, y₁=? and y₂= -2

$y=\frac{y_{1}+y_{2}}{2}\\5=\frac{y_{1}+-2}{2}\\5*2=y_{1}+-2\\10=y_{1}+-2\\10+2=y_{1}\\y_{1}=12$

SO, coordinates of endpoint A are (-7,12)

Write the standard equation of a circle with center (0, 3) and radius 7.

lbvjy [14]

Circle equation:
$(x - xo)^{2} + (y - yo)^{2} = {r}^{2}$

Center (0, 3)
Xo = 0
Yo = 3

Radius: 7
r = 7

So:

$(x - 0)^{2} + (y - 3)^{2} = {7}^{2}$
${x}^{2} + (y - 3)^{2} = 49$

Answer: x^2 + (y - 3)^2 = 49
