Un objeto cae de un globo aerostatico que se encuentra a una altura de 2304 metros. Si se desprecia la resistencia del aire y ademas sabemos que se desplaza 16metros en el primer segundo,48 metros en el siguiente segundo,80 metros en el tercer segundo,112 metros en el cuarto, y asi sucesivamente,¿A los cuantos segundos llegara a tierra?

The answer is "12".

Step-by-step explanation:

The AP value is:

try  with  

by adding the terms an

So, the correct answer is = 12.

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.
