Which are the solutions of the quadratic equation?
Given: x2 = 7x + 4
x2 = 7x + 4
0 = -x2 + 7x + 4
Answer: x = (7 + √33) / 2
Answer:
3 cm
Step-by-step explanation:
The cubed root of 27 = 3
Centre is at the middle or the midpoint of the diameter.
And the formula of midpoint is
For the given question, x1=-4, y1=2, x2=2, y2=-8
So we will get
And that's the required centre .
Why is the point (4, 3) there but not mentioned??
Anyways, the point that P (3, 0) is after rotating 180° about the origin is (-3, 0).
btw, for 180 rotations about O, just take negative value of (x, y)--> (-x, -y)
That way -(3), -(0) becomes (-3, 0)
