Atree farm initially has
9000 trees. each year, 10% of the trees are harvested
and 800 seedlings are planted.
a. write a recursive rule for the number of trees on
the tree farm at the beginning of the nth year.
b. what happens to the number of trees after an
extended period of time?

y(0)=5000 

y(1)=y(0)-.1(y(0)+450

 y(1)=.9y(0)+450

 y(n)=.9y(n-1)+450

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
