The extended warranty on a $960 dishwasher is 21% of the purchase price and lasts for eight years. what is the effective cost per year of the extended warranty?

$25.20

Step-by-step explanation:

Find 21% of $960

.21*960=201.6

Since there are 8 years, the cost per year will be the total cost divided by 8.

201.6/8=25.2

The cost per year is $25.20 on the extended warranty.

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.
