The equation for E(t) is E (t) = et. As for the room equation, maybe rewording it would help. The space is limited. 2m is being filled by every puppy the enters the room until t=9. After t=9, 3m of the playroom is being filled by every puppy who enters. How many cubic meters did the playroom would be filled with puppies at t=15.14.Hello Class, Here is my question for Discussion 2! Please let me know if I wrote this correctly. (Went with puppies, since I have a foster puppy). There are puppies running in at a rate E (t) and out of the playroom at the rate L (t) = % (per minute]. At t=0, the puppies are heard barking, at t = 1.84 the puppies begin to run in and out of the playroom. Finally, all the puppies leave for a potty break at t = 15.14. (All the puppies are inside at 15.14) How many puppies were in the playroom at t = 9? The playroom is lled with puppies at 21713 until t = 9, the puppies come in at 37712. How many cubic meters did the playroom ll at t=15.14
