I'm guessing the second part of the question asks you to find the tangent line to <em>f(x)</em> at the point <em>a</em> = 0. The slope of the tangent line to this point is
and when <em>a</em> = 0, we have <em>f(a)</em> = <em>f</em> (0) = -2, so the graph of <em>f(x)</em> passes through the point (0, -2).
Use the point-slope formula to get the equation of the tangent line:
<em>y</em> - (-2) = 3 (<em>x</em> - 0)
<em>y</em> + 2 = 3<em>x</em>
<em>y</em> = 3<em>x</em> - 2
6 to 5, 12 to 10, 18 to 15, 24 to 20, x to 25
Let's take a look at x/25 ratio, which has to be equal 6/5.
The answer is 30 inches.

So hmm check the picture below, that's about the circle and the endpoints, but notice, the endpoints make up a segment, namely the diameter of the circle, well.... let's see how long that is, because, the radius is half the diameter
now.. hmmm notice, the midpoint of the diameter, is the center of the circle, let's check that one out
now.. that we know what the center is, and what the radius is, well
