<span>h(x)=4x2−7x−17
a get like this:
</span>h(x)=f(x)−g(x) =6x2−3x−9-(2x2+4x+8)=6x2−3x−9-2x2-4x-8=4x2−7x−17
DFC equals 180 because all triangles add up to 180. And their sides are the same so 180/3=60
Answer:
3789
Step-by-step explanation:
Check the picture below.
keeping in mind that the point of tangency for a radius line and a tangent is alway a right-angle, since the "red" chord is parallel to the "green" tangent line outside, then the chord is cutting the "green" radius there in two equal halves at a right-angle, as you see in the picture.
we know the chord is 10 units long, so 5 + 5, since is perpendicularity with the radius will also cut the chord in two equal halves.
anyhow, all that said, we end up with triangle you see on the right-hand-side, and then we can just use the pythagorean theorem.

The third one is the answer for this question
