Answer:
2,826
Step-by-step explanation:
A tenth is the first place value after the decimal point
In this case, 2,826.<u>0</u>0
To round a number to the tenths place, we look at the hundredths place
If the number is 5 or more, we add 1 to the tenths place, and leave the numbers to the right 0's
If the number is 4 or less, we keep the number as it is in the tenths place, and leave the numbers to the right 0's
In this case, the hundredths place is a 0, which is less than 4, so we keep the 0 in the tenths place, and leave the to the right 0's.
Thus, our final answer is 2,826.
Answer:

Step-by-step explanation:
we have a exponential function of the form

where
y is the population of bacteria
a is the initial value
r is the rate of growth
x is the number of hours
we have
a=3,000 bacteria

For x=2, y=3,300
substitute


Apply square root both sides




substitute in the equation


<u><em>Predict how many bacteria will be present after 16 hours</em></u>
For x=16 hours
substitute


S*.05= ?*.05
