Answer:
The first one : decay
The second one : growth

When it's less than 1 and above 0 then it's a decay
You didn't provide the possible answers, but the smallest length of time will result in the least amount of interest.
Answer:
49.1 cm^2
Step-by-step explanation:
The appropriate area formula is ...
area = (1/2)(side 1)(side 2)(sin(angle between))
= (1/2)(10 cm)(12 cm)·sin(55°) = 60·sin(55°) cm^2
area ≈ 49.1 cm^2
