A linear function can be used to model the decrease in rainfall measured since 1880. The decrease in annual rainfall
has been a constant 0.12 inches per year. Let x represent the number of years since 1880, when measurements
began, and lety represent the annual rainfall. The initial measurement in 1880 was 54.3 inches. Use the linear
function to predict the annual rainfall in the 101st year after recordkeeping began. Round to the nearest hundredth.

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.
