What's with the gratuitous pi s?

The rule is to preserve inequalities we can only multiply both sides by positive numbers, or non-negative numbers (zero ok) for ≤ and ≥ (but not < and >).

To clear the denominator, first we need all positive factors down there so we multiply by

\dfrac{x-3}{x-3}=1

giving

\dfrac{x(x+2)^2(x-\pi)^3(x-3)}{x^2(x-3)^2(x+\pi)^4} \ge 0

Everything in the denominator is positive now, so we can clear it, multiplying it on both sides.  It vanishes on both sides.

x(x+2)^2(x-\pi)^3(x-3) \ge 0

Again we can divide both sides by the positive factors, which are the squares, including (x-π)².  We'll get zero when those factors are zero (and no zero denominator factor), so we have to remember to include x=0, x=-2, x=3 and x=π in the answer, but we eliminate 0 and 3 from this list because they give zero denominators.

x(x-\pi)(x-3) \ge 0

That's a lot easier to think about.  When x is really negative we're multiplying three negative numbers, so a negative result.

When x is really big we're multiplying three positive numbers, again a positive result.  

Between 0 and pi it's going to alternate.

<0 negative

0-3 positive

3-π negative

>π positive

Since zero is ok we can use ≤ or ≥ as appropriate, but we should also rule out anything that gives a zero denominator, as the truth value of 'undefined ≥ 0' is not really determined.

Answer: 0 < x < 3 or x ≥ π or x=-2

[I missed the x=-2 the first time around; sorry about that.]

What are the center and radius of the circle defined by the equation ?
RUDIKE [14]
You didn't give us the equation, but circle equations are in the form;
(x-h)^2 + (y-k)^2 =r^2 where h and k are the x and y coordinate of the center and r is the radius of the circle squared.

Please help!!! Which equation is in point-slope form and is depicted by the line in this graph?
Blizzard [7]
Y-y1=m(x-x1)
a point on the line is (x1,y1) and the slope is m

so
slope between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
so

points (-2,3) and (3,0)
slope is (0-3)/(3-(-2))=-3/(3+2)=-3/5
a point is (3,0) Or (-2,3)

so it could be
y-0=-3/5(x-3) or y-3=-3/5(x-(-2)) which is equal to y-3=-3/5(x+2)
that's the answer
