Step-by-step explanation:
Each digit goes in the place corresponding to its place value.
When no digit has a given place value, a placeholder is used. That is the purpose of zero, a great invention in the history of mathematics. It makes place-value number systems possible.
Answer:
a) decay
b) 2,950,000
c) 0.025
d) 
e) 2,409,123
Step-by-step explanation:
<u>Part (a)</u>
Exponential DECAY, since the population was decreasing annually.
<u>Part (b)</u>
Initial amount = 2,950,000 people (in the year 2000)
<u>Part (c)</u>
Decay factor = 2.5% = 0.025 (in decimal form)
<u>Part (d)</u>
General form of exponential decay function:

where:
- a = initial amount
- r = rate of decay (in decimal form)
- x = time (in years)
Given:


<u>Part (e)</u>
To determine the city's population in 2008:


yes because 25 divided by 5 equals 5
4d + 3 - d + c
Sum together everything that has the same letters:
4d - d = 3d
Put this answer into the question:
3d + 3 + c
That’s your answer as there is no further working we can do! :)
