A graphing calculator is recommended. A bacteria culture starts with 100 bacteria and doubles in size every half hour. (a) How m
any bacteria are there after 3 hours? bacteria (b) How many bacteria are there after t hours? y = bacteria
1 answer:
Answer: a) 800
b)
Step-by-step explanation:
The exponential growth function is represented by :-
, where A is initial value , b is the multiplicative rate of change and t is the time period.
Given : A bacteria culture starts with 100 bacteria and doubles in size every half hour.
i.e. A = 100 and b=2
Then, the exponential growth function to find the number of bacteris after t hours :_
At x=3
Hence, the there are 800 bacteria after 3 hours.

Answer:
Interest She'll make in a year is $30.10125
Step-by-step explanation:
Interest = PRT ÷ 100
Principal = $523.50
Rate = 5³/₄% = 5.75%
Time= 1year
Interest I = (523.50 × 5.75 × 1) ÷ 100 = $30.10125
Interest She'll make in a year is $30.10125
