Answer: Option A

Step-by-step explanation:
Note that for the initial year, 1990, the population was 5.3 billion.
The exchange rate is 0.09125 billion per year. In other words, each year there are 0.09125 billion more people.
In year 2 there will be 0.09125 * 2 billion people
In year 3 there will be 0.09125 * 3 billion people
In year 4 there will be 0.09125 * 4 billion people
In year t there will be 0.09125 * t billion of people
So the equation that models the number of people that there will be as a function of time is:

Where
is the initial population
billion
r is the rate of increase
billion per year
finally the equation is:

The correct answer is option A.

your answer would be 330
Step-by-step explanation:
Answer:
<em>First term of the given series = 4</em>
<em>The last term of the given series = 11</em>
Step-by-step explanation:
<u><em>Explanation</em></u>
<em>Given that the sum of the series</em>
<em> ∑⁸ₙ₋₁ (n+3)</em>
The
term of the given sequence
aₙ = (n+3)
Put n=1
a₁ = 1+3 = 4
Put n=2
a₂ = 2+3 =5
Put n=3
a₃ = 3+3 = 6
Put n=4
a₄ = 4+3 =7
Put n=5
a₅ = 5+3 =8
Put n=6
a₆ = 6+3 =9
Put n=7
a₇ = 7+3 = 10
Put n=8
a₈ = 8+3 =11
The sequence of the given series
4,5,6,7,8,9,10,11
<u><em>Final answer:-</em></u>
<em>First term of the given series = 4</em>
<em>The last term of the given series = 11</em>
<em> </em>
