Is this table proportional?

No, the table is not proportional.

Proportional means that it has a consistent change in ratio. In this table, 4:5 is the ratio. So, for the table to be proportional, the next numbers would be 8 (mins) and 10 (ft), 12 (mins) and 15 (ft), and so on.

Thus proving that the table given is not proportional.

I hope this helps!

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.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
