Answer: Yes, Atoine is correct.
Step-by-step explanation:
The roots of a quadratic function are also known as the solutions or the zeros of a function. Here is how we get them:
1. Let y=0 to find the x-intercept(s).
0=x^2+25
2. Subtract 25 from both sides.
−25=x&2
3. Take the square root of both sides.
±√−25
=x
4. Simplify √−25 to √25ı.
±√25ı=x
5. Since 5×5=25, the square root of 25 is 5.
±5ı=x
6. Switch sides.
x=±5ı
The equation above is not a real solution that represents a line.
Therefore, there are no x-intercepts.
Answer:
√85
Step-by-step explanation:
A (-3 , 4) B (4 , -2)
AB² = (4 - -3)² + (-2 -4)² = 49 + 36 = 85
AB = √85

Answer:
The radius is r=5 units
Step-by-step explanation:
we know that
The equation of the circle in standard form is equal to
where
(h,k) is the center and r is the radius
we have
Convert to standard form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square twice. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
therefore
The center is the point (6,-3) and the radius is r=5 units
