Idon't understand this question. does anyone know how to do it?

y = 8(.88)^x

y = 4.221855 for the fifth reduction

Step-by-step explanation:

We can use the formula

y =ab^x

where a =the initial value

b= 1 -percent decrease

a = 8 inches

b = 1-12%

   = 1-.12

   = .88

y = 8 (.88)^x

The fifth reduction is

y = 8 (.88) ^5

y = 4.221855

answer: h

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.
