A population of 60 foxes in a wildlife preserve triples in size every 15 years. The function y = 60 times 3^x, where x is the number of 15-year periods, models the population growth. How many foxes will there be after 30 years?

After 30 years there will be foxes. (Type a whole number.)

Question 2 (essay worth 10 points) (03.02 mc) in δabc shown below, point a is at (0, 0), point b is at (x2, 0), point c is at (x1, y1), point d is at x sub 1 over 2, y sub 1 over 2, and point e is at the quantity of x sub 1 plus x sub 2 over 2, y sub 1 over 2: triangle abc is shown. point d lies on segment ac and point e lies on segment bc. a segment is drawn between points d and e. point a is at the origin. prove that segment de is parallel to segment ab.
