Answer:
Center = (5,-3) and radius = 7
Step-by-step explanation:
(5) If Oskar bisects the diameter of a circle, what is he trying to construct the radius of the circle.
(6) The given equation is :

The general equation of circle is given by :
...(1)
Where
(a,b) are the coordinates of the centre and r is the radius.
The given equation can be written as :
..(2)
Comparing equation (1) and (2) we get :
a = 5, b = -3 and r = 7
So,
Center = (5,-3) and radius = 7
Hence, this is the required solution.
Answer:
a) 5/-6, - 5/6
b) 7/-2, -7/2
Step-by-step explanation:
Answer:
g(f(x)) = -x - 18
Step-by-step explanation:
2x - 6( (x + 6) / (2) )
2x - 3( x + 6)
2x - 3x - 18
-x - 18
Answer:
210 divided 2 1/2= 84....
Answer:
±3i
Step-by-step explanation:
Given the value ±√-9, we are to express the value using the imaginary number 'I'
±√-9 = ±√9×-1
= ±√9 × √-1
In complex number, √-1 = i
The expression becomes;
±√9 = ±3 × i
±√9 = ±3i
Hence the value in simplified form is ±3i
