Answer:

- 4 - 5i

Step-by-step explanation:

The centre of the circle is the average of the endpoints

centre = (- 2 + i - 6 - 11i ) ÷ 2

= (- 8 - 10i ) ÷ 2

= - 4 - 5i

Answer:

0.25

Step-by-step explanation:

we have

$(-0.5)^2$

we know that

$-0.5=-\frac{1}{2}$

substitute

$(-\frac{1}{2})^2=(-\frac{1}{2})(-\frac{1}{2})$

Remember that

$(-1)(-1)=1\\(-1)(1)=(-1)$

$(-\frac{1}{2})(-\frac{1}{2})=\frac{1}{4}=0.25$

According to the square root property, the solution set of x 2 = 25 is {±5}. True False

babymother [125]

I believe the correct answer is true. According to the square root property, the solution set of x^2 = 25 is {±5}. The square root property is one method that is used to find the solutions to a quadratic (second degree) equation. This method involves taking the square roots of both sides of the equation. Hope this answers the question.
