Answer:
r = 
Step-by-step explanation:
The distance from the centre to a point on the circle is the radius r
Calculate r using the distance formula
r = 
with (x₁, y₁ ) = (0, 0 ) and (x₂, y₂ ) = (2, 5 )
r = 
= 
= 
=
Answer:
the answer is for the question is B- Sue's estimate is best because she gets more tails
I assume your "reasons" mean "roots" or "zeros"
if 3 is a root, plug x=3 in the equation, you can find n:
3²+(n-1)*3+6=0
3(n-1)=-15
n-1=-5
n=-4
Plug n=-4 in the original equation: x²-5x+6=0
factor: (x-3)(x-2)=0
x=3, which we already know
or x=2, which is the value of m+4
m+4=2
m=-2
The ratio is equivalent because 1/20 is 5 which means 9/10 is equal
