Question

a sample of bacteria was placed in a petri dish. the number of bacteria changes exponentially over time. the graph describes the number of bacteria over time (in hours). what was the samples initial size? bacteria

Explanation:

Step1: Identify initial - time on graph

Initial time is when time \(t = 0\).

Step2: Read number of bacteria at \(t = 0\)

From the graph, when \(t=0\), the number of bacteria on the y - axis is 50.

Answer:

50
