<span>x^3 - 4x^2 - 7x + 10 = 0</span>
To find the difference between these numbers you need to subtract 8.3 - 3.9
and that equals 4.4<span />
I think it is 13 by looking at the angle and numbers.
Answer:
Center (-13,11) , radius 3
Step-by-step explanation:
The given circle has equation

We compare this to the general equation.

where (-a,-b) is the center.
This implies that;
2a=26

2b=-22
b=-11
The center is therefore (-13,11)
The radius is given by



The radius is 3
