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:
the answer to this problem is -16 use the operation by subtracting 5 from 5 and -27 then dividing
Answer:
linear functions will create a straight line when graphed but if you were to graph a non linear equation then it would not create a straight line
Step-by-step explanation:
The plant is 4 and 1/4 inches above ground
(34/4)-(17/4)=17/4
Equation: j/9 = 5
Answer: j = 45
