bacteria are measured to be in a dirt sample that weighs 11 grams

. Use scientific notation to express the number of bacteria that would be in a sample weighing 19 grams.

the answer is c

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.

3; 9 is 8 to -4

step-by-step explanation:

but which class are u may know that first
