A. amplitude = 1, period = 1/2π
B. amplitude = 2π, period = -1
C. amplitude = 1/2π, period = 1
D. amplitude = -1, period = 2

squares, rhombus, rectangles

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

costs the what? what is the cost of the pants?

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.

correct answer is c. just did it
