A battery is charged. The percentage of the battery’s capacity that is charged as a function of time (in minutes) is graphed.
How many percentage are added every 6 minutes?
A- 12 percent
B- 6 percent
C- 10 percent
D- 2 percent

  A- 12 percent

Step-by-step explanation:

You can see on the graph that the charged percentage of capacity changes from 40 to 50 in 5 minutes. Then the increase in 6 minutes will be slightly more than 10 percent.

The linear rate is (10%)/(5 min) = 2%/min, so in 6 minutes it will be

  (2%/min)×(6 min) = 12%

This calculation is consistent with our observation from the graph.

Every 6 minutes, 12 percent is added to the capacity.

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.
