Answer:
I would say 50%
Step-by-step explanation:
Answer: Area: 16 square inches
Length of missing edge: 2 inches
Step-by-step explanation: Since the 2 missing squares are the same we can deduct that the length is 2 since 24÷12 is 2. That comes from the other squares. And 8 x 2 gives 16.
50 cm = 1/2 m
3 m ÷ 1/2 m = 6
It will take him six days.
For this case we have a function of the form:
Where,
A: initial population of bacteria
b: growth rate
x: number of hours
Since the diameter is double every hour, then:
We must now look for the value of A.
To do this, we evaluate an ordered pair of the graph:
For (1, 2):
Clearing A we have:
Then, the function is given by:
For after 9 hours we have:
Answer:
the diameter of the bacteria after 9 hours is:
10 x 10 ^ 7
Should be
1.0 x 10 ^ 8
