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
You have to simplify and then get x
Mark points (0,0), (-1,-1), (1,-1), (-2,-4), (2,-4)
The equation that shows the relationship between the elevation of the feather, y, and the number of Seconds it has been falling is y = -2x + 10
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Independent variables represent function inputs that do not depend on other values, while dependent variables represent function outputs that depends on other values.
Let x represent the time in seconds for the bird feather to reach 10 feet.
Hence:
y = -2x + 10
The equation that shows the relationship between the elevation of the feather, y, and the number of Seconds it has been falling is y = -2x + 10
