If there are 81 gold coins with one of them a fake lighter coin, describe a non-adaptive solu- tion that will find the fake coin using 4 weighings of a pan balance. (hint: how many four letter words can be made using only the letters a, b and c? use these words to label the coins.) non-adaptive solution

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'

45

step-by-step explanation:

to find a percentage, add a decimal in front and multiply it by the other number.
