Natasha is observing the growth of a population of bacteria. she started out with 250 bacteria cells. the population of bacteria quadruples every hour. use x to represent the number of hours and y to represent the population of the bacteria. enter an equation that represents this scenario in the box.

Step-by-step explanation:

The growth of a population of bacteria can be represented by exponential growth function,

where,

y = the population of the bacteria after x hours,

x = the number of hours,

a = initial population of bacteria,

r = rate of growth,

At the beginning the number bacteria was 250 and the population of bacteria quadruples every hour i.e rate of growth is 400% or 4 per hour.

Putting all the values,

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
