D
Step-by-step explanation:
|-6x+3|=0
-6x+3=0
-6x=-3
x=-3/-6
x=1/2
Answer: 3 boxes
Step-by-step explanation:
If each box is 12, 3 Times 12 is 36 plus the 2 for each box gives you 42
The population of the bacteria after 7 hours is 230 bacteria.
An exponential function is given by:
y = abˣ
where y, x are variables, a is the initial value of y and b is the multiplier.
Let y represent the population of bacteria after x hours.
Given that he starts his experiment with 200 bacteria, hence
a = 200
The bacteria grow at a rate of 2% per hour, hence:
b = 100% + 2% = 1.02
The exponential equation becomes:
y = 200(1.02)ˣ
After 7 hours:
y = 200(1.02)⁷ = 230
The population of the bacteria after 7 hours is 230 bacteria.
