Interpreting Derivative ValuesGrowth of yeast cells In a controlled laboratory experiment, yeast cells are grown in an automated cell culture system that counts the number P of cells present at hourly intervals. The number after t hours is shown in the accompanying figure." style="" width="250"\u003ea. Explain what is meant by the derivative P'(5). What are its units?

Accepted Answer

Step 1: Understand the meaning of the derivative P'(t). The derivative P'(t) represents the rate of change of the number of yeast cells (P) with respect to time (t). In simpler terms, it tells us how quickly the population of yeast cells is growing at a specific time. Step 2: Interpret P'(5). Specifically, P'(5) refers to the rate of change of the yeast cell population at t = 5 hours. It provides the instantaneous growth rate of the yeast cells at that moment in time. Step 3: Determine the units of P'(5). Since P represents the number of yeast cells and t represents time in hours, the derivative P'(t) will have units of 'cells per hour.' This is because it measures the change in the number of cells (P) per unit of time (t). Step 4: Relate P'(5) to the graph. To estimate P'(5) from the graph, you would examine the slope of the tangent line to the curve at t = 5. The steeper the slope, the faster the growth rate at that time. Step 5: Explain the significance of P'(5). The value of P'(5) is important in understanding the dynamics of yeast cell growth. It helps researchers determine how quickly the population is expanding at a specific point in the experiment, which can be useful for optimizing growth conditions or predicting future population sizes.
