Will I Need To Show Anything More Than My Passport And Visa?

Good day. I received my Brazilian Visa. I already have my U.S. Passport, airline ticket and itinerary. Do I need to show border agents anything else? Do I have to show them my hotel reservations as well? Sometimes though, border agents can really mess you up because they’re having a “bad day.” And they can take their anger out on you, finding something very small or be nitpicky and then sending you back for no reason. Please I am not trying to have that. Please tell me, my trip is at the end of April and this is my first time going to Brazil. Thank you all so so so much.
