Answer:
I do not know the answer but I think it is (1,0) x (-3,4)
Step-by-step explanation:
Step-by-step explanation:
circumference of a circle
U = 2 x pi x r
what you know:
U = 13
rearrange and solve for r
U/(2 x pi) = r
We are given mid-point (-11, 18).
One end point (-5, 10).
Let us take coordinate of other end points is (x,y).
Therefore,
Given mid point (-11, 18).
Therefore,
and
Multiplying both sides by 2 in both equations, we get
x-5 = -22 and y+10 =36.
x = -22+5 and y = 36-10
x = -17 and y = 26.
<h3>Therefore, corrdinates of other end point is (-17, 26).</h3>
Answer:
Step-by-step explanation:
Compare the powers
x² + 4x + 4 = 9x + 18
x² + 4x + 4 - 9x -18 = 0
x² -5x -14 = 0
x² -7x + 2x - 2 *7 = 0
x(x-7) + 2(x - 7) = 0
(x-7)(x+2) = 0
x - 7 = 0 or x + 2 = 0
x = 7 or x = -2
