Answer:
-2
Step-by-step explanation:
The rise between adjacent points (left to right) is -6, while the run is 3. Then the slope is ...
m = rise/run = -6/3 = -2
The slope of the line is -2.
The measure off DF is 11.
In a circle inscribed within a triangle, the distance from each vertex of the triangle to the two nearest touchpoints (points of tangency on the circle) are equal. Since SD=4, DT=4 as well. Since UF=7, then FT=7.
DF=DT+TF=4+7=11.
If f(x) is some function with period T, then f(x) = f(x+T) for all x in the domain.
In this case, T = 5 is the period so
f(x) = f(x+5)
f(3) = 10
f(3) = f(3+5) = f(8) = 10
f(8) = f(8+5) = f(13) = 10
Therefore, f(13) = 10
The final answer is 10
