If we assume that 2010 is t=0 what is the initial value and what does it mean? Does the data best fit a linear or an exponential model?
What equation best models this data?

Answer:
309.35 million, the initial number of people in 2010
Step-by-step explanation:
The initial value is when t =0, so looking at the table, (t=0 in 2010) , the initial value is 309.35 million
This is the starting population when use for our exponential growth or decay model. It is the number of people at our initial time. Since the population is increasing, w have exponential growth
The initial value is 309.35
It means that in the year 2010 (starting year) the population was 309,350,000 people or written another way "309.35 million". The second way is more short so probably the more preferred method.
To find the value 309.35, simply look at the table under the value t = 0.

The model of the shaded region is 0.80. And if 8 square boxes were shaded, then Koran's model was right.
What is a percentage?
A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
Koran showed 0.08 with the model.
In the model,
there are ten columns and ten rows.
That means, 100 square boxes.
And the shaded region have 8 columns and 10 rows.
That means, 80 square boxes.
Koran showed the percentage of shaded region of the model.
That is, 0.08 is 8%.
So let n be the percentage of shaded region.
So, 80 =n x 100/ 100
n = 80%
And 80% in decimal is 0.80.
And if Koran wants 0.08.
That means, 8% of shaded region.
So 8% 0f 100 is 8 square boxes.
Therefore, if 8 square boxes were shaded, then Koran's model was right.

Constant
Step-by-step explanation:
For a straight line for example,
Take any two points from the line and find the slope,
it will be the same value for any 2 points chosen
So throughout the graph, the slope/rate of change is not changing
That is
Throughout the graph rate of change/slope is constant

Final answer:
3² x 5² is a multiplication of numbers, none of which are divisible by 2. Hence, the resulting number will be odd, as even numbers require a factor of 2.
Explanation:
The number Dawson wrote is the result of the factorization 3² x 5². Here, 3 and 5 are the bases and the exponents are 2. The exponentiation means the base number is multiplied by itself as many times as the value of the exponent. Therefore, 3² means 3 is multiplied by itself once, and 5² means 5 is multiplied by itself once.
In order to determine if the resulting number is even or odd, we don't have to perform the calculations. For any number to be even, it must be divisible by 2. If there isn't a factor of 2 in the number, the resulting product will be odd.
In this case, neither 3 nor 5 are divisible by 2. Hence, when you multiply them, no matter how many times, the result will always be an odd number. Therefore, the number obtained from 3² x 5² is odd.
