Suppose P(t) represents a fish population at time t, where t is measured in weeks. Explain the meaning of the final term in the equation (−15). The term −15 represents a harvesting of fish at Correct: Your answer is correct. rate — in this case, 15 Correct: Your answer is correct. . This is the rate at which fish are caught.

The equation is

DP/DT=0.08P(1-P/1000)-15

The final term -15 tell us that fish are caught 15 per week.

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
