Answer:
Step-by-step explanation:
f(x)=(x-(-4))(x-3)(x-8)
f(x)= (x+4)(x-3)(x-8)
If circumference = (2 * PI * radius) then we solve for radius
radius = circumference / (2 * PI)radius = 25.142758 / 22/7 * 2radius = <span><span>4.00

Answer:
A system of the equation of a circle and a linear equation
A system of the equation of a parabola and a linear equation
Step-by-step explanation:
Let us verify our answer
A system of the equation of a circle and a linear equation
Let an equation of a circle as
..........(1)
Let a liner equation Y = x ............(2)
substitute (2) in (1)

so Y =
so the two solution are (
)
A system of the equation of a parabola and a linear equation
Let equation of Parabola be 
and linear equation y = x
substitute

Y = 0,1
so the two solutions will be (0,0) and (1,1)
I think its
x² - 2x + y² + 6y - 6 = 0
x² - 2x + y² + 6y = 6
(x² - 2x + 1) + (y² + 6y + 9) = 6 + 1 + 9
(x - 1)² + (y + 3)² = 16
center: (h, k) = (x, y) = (1, -3)
radius: 4
