The answer is d, ive had this question before and thats what i put
The standard equation of a circle:
(y-k)² + (x-h)² = R² (1), where R is the radius and h, k are the coordinates of the center.: C(h, k)
In the problem the coordinates of the center C(2,-1).
Replace in (1) h by 2 and k by -1:
(y+1)² + (x-2)² = 25
Answer is C. 0.6 (6 is repeating)
hope it helps
Answer:
a sqrt(2) - sqrt(3)
----------------------- + 2i
2
Step-by-step explanation:
(sqrt 2/2 +i) - (sqrt 3/2 -i)
Add the real terms
sqrt(2) / 2 - sqrt(3) /2
sqrt(2) - sqrt(3)
-----------------------
2
Now add the imaginary terms
i - -i
i+i
2i
Put them back together
sqrt(2) - sqrt(3)
----------------------- + 2i
2
