Using an exponential function, it is found that the multiplier that would allow you to predict the population of bacteria after 2 hours is of 9.
<h3>What is an exponential function?</h3>
An exponential function is modeled by:
In which:
In this problem, the bacteria triples every hour, hence the rate of change is b = 3, and the equation is:
Hence, after 2 hours:
Which means that the multiplier is of 9.

Answer:
Step-by-step explanation:
1. Find the eighth term
You have an arithmetic sequence. It starts at 75 and each successive term is 5 more than the one preceding it
The general formula for the nth term (aₙ) is
aₙ = a₁ + (n - 1)d
where a₁ is the first term and d is the common difference (5) between consecutive terms. Thus,
a₈ = 75 + (8 - 1) × 5 = 75 + 7 × 5 = 75 + 35 = 110
2. Find the sum
The formula for sum of the first n terms of an arithmetic sequence is
So
Answer:
60 degrees
Step-by-step explanation:
ebd + dbc = 180 because they make a straight line
120 + dbc = 180
dbc = 60
the three angles in a triangle always add up to 180 degrees
bcd + dbc + cdb = 180
60 + 60 + cdb = 180
120 + cdb = 180
cdb = 60
Answer:
40 mph
Step-by-step explanation:
Times the distance by the mph to get the speed.
Have a great day! :D
