Thank you for the opportunity to help you with your question!

Precentate usable=100- percentage filed

= 100-100(1-e^-.1t)=100e^-.1t
at t=6
percentage usable=100e^-.6=54.9percent


2nd

a

f(9)=220(1-0.943e^(-0.15x8))=157.35. rounding to the nearest whole number we get 157

b

find df(t)/ dt = 30.768*e (-4/25*t) 

then plug in t= 6 ==> 11.78 cm 

c

220cm

Please let me know if you need any clarification. I'm always happy to answer your questions.
