The formula NEXT = 2 • NOW models the number of bacteria in a test tube. There were 10 bacteria in the test tube after the first
hour. How many bacteria will be present in the test tube after the fifth hour?
2 answers:
Answer:
160
Step-by-step explanation:
NEXT = 2 • NOW
Implies
a(n+1) = 2 × a(n)
a(1) = 10
a(2) = 20
a(3) = 40
a(4) = 80
a(5) = 160
Answer:
160 bacteria
Step-by-step explanation:
We can create an exponential function of the form:
, where a is the initial value, b is the rate, and x is the time.
Here, a = 10 and b = 2, so our equation is:


We want the number of bacteria present after the fifth hour, or when x = 5, so we have:


There were 160 bacteria.

Answer:
q = 1/4
Step-by-step explanation:
-5/4 - (-1/4) = -1
-1/(q-1/2) = 4
-1 = 4(q-1/2)
-1 = 4q - 2
1 = 4q
q = 1/4
Answer:
20000 millimeteres
Step-by-step explanation:
15/24 because 5/3 X 1/4 = 5/12 X 3/2= 15/ 24
8x5=40
So the car is 40 inches long
- the mode :is the most repeated value
- for example if the question asked you to find the mode among a set of numbers like:2,3,2,4,5,5,2
- the mode will be 2 because 2 is the most repeated value
