Find the length of ED.

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.

Answer:

L(4,-3)  -> L'(4,9)

M(4,3)  -> M'(4,3)

N(-4,3) -> N'(-4,3)

K(-4,-3) -> K'(-4,9)

Step-by-step explanation:

Reflection of an object means to flip that object on a line called the axis of reflection or line of reflection or mirror line.

Line of reflection here is y = 3

So, after a reflection over the line y = 3

Co ordinates

L' =  (4,9)

M' = (4,3)

N' = (-4,3)

K' = (-4,9)

Final answer:

A reflection over the line y=3 changes the y-coordinate of a point to 2*3 minus its original y-coordinate, keeping the x-coordinate the same.

Explanation:

To find the coordinates of the vertices after a reflection over the line y=3, one should understand that a reflection over a horizontal line, such as y=3, changes the y-coordinate of each point while keeping the x-coordinate the same. For instance, if you have a point (a, b), after reflecting over the line y=3, the new point would be (a, 2*3-b). This is because the difference between the y-coordinate of the point and the line of reflection (3 in this case) would be the same before and after reflection, but with a different sign.

For example, if you have a vertex at (2, 5), to find its new position after reflection, you would keep the x-coordinate (2) the same, and calculate the new y-coordinate as (2*3 - 5) = 1. So, the reflected vertex would be at (2, 1). Apply this same method to all vertices to find their new positions after reflection.
