In a laboratory, the number of bacteria in a petri dish after t days is modeled by the function b (t) = startfraction 300,000 over 1 999 e superscript negative 0.5 t baseline endfraction. what does 300,000 represent? initial number of bacteria in the petri dish number of bacteria in the petri dish after one day number of bacteria in the petri dish at any given time maximum number of the bacteria the petri dish can hold
