Answer:
122.6 million
Step-by-step explanation:
Figure the value of t, then put that into the formula and do the arithmetic.
t = 2007 =1991 = 16
n(16) = 89e^(0.02·16) = 89·e^0.32 ≈ 122.6
The model predicts a rat population of 122.6 million in 2007.

L x W will tell you how much square foot there is so 8x8=64 since its a square and all sides are the same
Each square foot is $6 so 64 x 6 = $384
Answer:
Option D.
Step-by-step explanation:
A reflection is a mirror image across the a line of reflection. The image will be perpendicular to the line of reflection and equal distance from it as the pre-image is too. This means that point G will move horizontally across the y-axis the same distance it is currently from the y-axis. It is 2 units away from the y-axis so G' will be 2 units on the other side or -2. This makes G' (-2,2). Notice this is the same coordinates of G only multiplied by -1. When reflecting a shape across the y-axis, the x-coordinates of the points are multiplied by -1.
So G (2,2) becomes (-2,2).
So F (-2,-1) becomes (2,-1).
So H (4,-3) becomes (-4,-3).
