Ahuman hair was measured to be 8.0×10−4 inch thick. a cat hair was measured to be 4.0×10−1 inch thick. how much greater is the thickness of the cat hair than the human hair? write the answer in standard form.

500 times thicker.

Step-by-step explanation:

We have been given that a human hair was measured to be inch thick. A cat hair was measured to be inch thick.

To find the thickness of cat hair is how many times greater than human hair, we will divide thickness of cat hair by thickness of human hair as:

Using exponent property , we will get:

Therefore, the cat hair is 500 times thicker than human hair.

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.

i believe the answer is c.
