Answer:
The initial number of bacteria in the culture was 1949
Step-by-step explanation:
The relative growth rate for a certain type of bacteria population is 78% per hour.
As we know the growth of bacteria is exponential function.

where,
P is population of bacteria after n hours.
P₀ is initial population.
r is rate of growth per hour
n is number of hours
A small culture has formed and in just 5 hours the count shows to be 34,820 bacteria in the culture.
P = 34820 , n = 5 , r = 0.78



Hence, The initial number of bacteria in the culture was 1949
A = pi(r) ^2
A = 3.14(5) ^2
A = 15.7 ^2
A = 246.49
Hope this helps.
I think it’s C because inverses are basically the reciprocals of each other. These make 90 degree angles and the slopes product should be -1. C looks like the lines are perpendicular so I would go with that
If she works 48 hours per week and she earns 16 dollars per hour, we can find the weekly wage by multiplying 48 by 16. This gets us a weekly wage of $768 (Choice A).
