It has 5 roots. You can determine this by the degree of the polynomial
1. Arc KL = 23
2. Arc LON = 203
3. Arc OM = 113
4. Arc KNL = 180
5. 157
hope this helps !
(fog)(x)=f(g(x))
f(g(x))=3(-4x+7)+5
f(g(-4))=3(-4(4)+7)+5=3(-16+7)+5=3(-9)+5=-27+5=-22
(fog)(-4)=-22

Looking at the triangle, you can see that point D bisects line segment AB and that point E bisects line segment BC. In fact, you can easily determine that triangles ABC and DBE are similar triangles with DBE having sides that are half the length of the respective sides in ABC. And since line segment DE corresponds to line segment AC which is 12.6 units long, line segment DE is 12.6/2 = 6.3 units long.</span>
This is found by the volume of a cone formula
Where b is the base and h is the height
