The answer is B) 4:5
First write the ratio out. To find the simplified expression, divide by the greatest common factor (GCF). In this case, the GCF of 28 and 35 is 7.
28:35

=4:5
4:5 is the simplest form because you cannot simplify it further.
Answer:
f(2) = 13.6
Step-by-step explanation:
Using the recursive formula and f(1) = 4 , then
f(2) = 0.4 f(1) + 12 = (0.4) × 4) + 12 = 1.6 + 12 = 13.6
