A circle with center
and radius
has equation

If we substitute
in this equation, we have

This equation has two solutions (i.e. the line intersects the circle in two points) if and only if the determinant is greater than zero:

The expression simplifies to

The solutions to the associated equation are

So, the parabola is negative between the two solutions:

Answer: I would say the 3rd answer. "If she takes a random sample of the population of working adults in her town, the mean for that group is likely close to the mean for the entire group."
Answer:
10
Step-by-step explanation:
Answer:
(-2, 3 )
(-1, 2
)
(0, 2)
(1, 1
)
(2, 1)
Step-by-step explanation:
You just simply substitue the values given into the equation, and the answer worked out will be the value of y.
a = -
× -2 + 2 = 1 + 2 = 3
b = -
× -1 + 2 =
+ 2 = 2
c = -
× 0 + 2 = 0 + 2 = 2
d = -
× 1+ 2 = -
+ 2 = 1
e = -
× 2+ 2 = -1 +2 = 1
Hope this helps you :)
