A biologist studied the populations of white-sided jackrabbits and black-tailed jackrabbits over a 5-year period. The biologist modeled the populations, in thousands, with the following polynomials where x is time,
in years.
White-sided jackrabbits: 9.7x’ - 0.8x + 2.3
Black-tailed jackrabbits: -1.10 + 7.7r + 5.4
What polynomial models the total number of white-sided and black-tailed jackrabbits?
C.
1-8.6r? +6.9x - 7.7
b. 8.6x6.9.r + 7.7
8.6r +6.9x + 7.7
d. 8.6r -6.9.x - 7.7

step-by-step explanation:

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.
