Bacteria is known to grow exponentially. The function B (h) = 82(1.25)^h represents the number of bacteria, B (h), as a function of hours, h. How many bacteria ill there be after only 5 1/2 hours to the nearest bacteria? What is B (5 1/2)?
A. 257
B. 564
C. 279
D. 280
To calculate the number of bacteria after 5 1/2 hours, you need to substitute h = 5.5 into the function B(h).
B(5.5) = 82(1.25)^5.5
Using a calculator, you can calculate B(5.5) ≈ 279.12077.
Rounded to the nearest whole number, B(5.5) is approximately 279.
Therefore, the correct answer is C. 279.
