Answer:
Center: (0,0)
Radius: 5
Step-by-step explanation:
Let O(xo,yo) be the center (of the circle) with the coordinates xo, yo.
If R is the radius, then we have:
(x-xo)²+(y-yo)²=R².
In our case: x²+y²=25, the center is at (0,0), and R²=25, so R=5
Answer:
The answer is : A
Step-by-step explanation:
I dont think you really care about how to do it. Also, I tried my best. I know you really need this and I really need Brainliest so lets help eachother out.
1) f(0) means to find y value when x= 0
x=0, y=2, so f(0) =2
2) f(x) = 0
y=0,x=?
When y=0, x=4
3) f⁻¹(0),
This is an inverse function of f(x),
that means that for f⁻¹, that values of x become y, and values of y become x.
f⁻¹(0)
"0" is y from the graph, when y=0, x=4, so
y=0, f⁻¹(0) = 4
4) f⁻¹(x)=0,
means that on this graph we need x=0, y=2,
so f⁻¹(2)=0,
x=0
For function we had
x=0, y=2
x=4, y=0
For f⁻¹ inverse function we have (x becomes y, and y becomes x)
x=2, y=0
x=0, y=4
48. 6 legs x 8 ants = 48 legs.
