a colony of bacteria is growing exponentially according to the function below,
where tis in hours. what will the approximate number of bacteria be after 7
hours?
b't) = 4.087
o a. 45,674
o b. 1082
o c. 270
o d. 635,818

when you were  given with the situation of bacteria multiplying into colonies,and  also with the function of B(t)= 4e^0.8t where t is the time of multiplication.you  just have to substitute the given time of 7 hours to find the  final count. The answer is approximately 1082.

Answer is  B. 

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
