This table shows some values of an exponential function.
x | y
0 | 0.25
1 | 1.25
2 | 6.25
3 | 31.25
what is the function?

A. f(x) = 5(0.25^x)
B. f(x) = 0.25(1.25^x)
C. f(x) = 0.25(5^x)
D. f(x) = 0.25(1/5)^x

$25 becasue a 10 increase would make it from 80 to 50

the area of the piece of paper =   27- inch square.

so, the length of the square piece of paper = = .

the side of the triangle cut = =

also the side of the small square cut =

so, the area of each triangle cut = 1/2 * .

so, the area of 4 triangles cut =

area of a small square cut =

total area of 4 triangles cut and a small square cut = 6+3 = 9 square inches.

reaming area of the octagonal window   = 27 - 9 = 18 square inches.
