Which recursive formula can be used to generate the sequence shown, where f(1) = 9.6 and n > 1? 9.6, –4.8, 2.4, –1.2, 0.6, ... A) f(n + 1) = –0.5f(n)
B) f(n + 1) = 0.5f(n)
C) f(n + 1) = f(0.5n)
D) f(n + 1) = f(–0.5n)

In the diagram of circle a what is m

Write the following as a base and exponent

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2
