Which of the below options shows the correct format for scientific
notation?

00.0602

1

34.765 x 10^-4

2.56 x 10^2

(b) 1

(c) 34.765 x 10^-4

(d)  2.56 x 10^2

Explanation:

Scientific notation is a way of expressing numbers that are too big or too small to be conveniently written in decimal form.

In this case, the scientific notation of 00.0602 will be 6 X 10⁻⁴

1 , 34.765 x 10⁻⁴  and 2.56 x 10² are already in scientific notation form.

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.
