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?

will give brainliest!

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.

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

B

Step-by-step explanation:

The trick you need to employ is that when the rock hits the ground, the timer stops. So h must be taken as 0.

0 = - 16t^2 + 255            Set up the equation

- 255 = - 16t^2                Divide by -16

15.9375 = t^2                  Switch

t^2 = 15.9375                   Take the square root of both sides.

sqrt(t^2) = sqrt(15.9375)

t = 3.992 seconds

The closest answer is B
