Answer:
The answer is:
{(2,2),(4,4),(6,6),(8,8)} is a function
{(0,3),(3,5),(5,6),(8,4)} is a function
{(1,2),(3,3),(4,8),(6,3)} is a function
{(3,4),(5,2),(5,6),(7,3)} is not a function
Step-by-step explanation:
Sorry I don't have an explanation, but I know these are correct because I took the test and got this correct. ;)
1 function {(2,2),(4,4),(6,6),(8,8)} written is a function the other following coordinates are not functions due to it not being a straight line as a 'proper' function should be.
First, we need to find the amount of dip that was divided amount the two friends.
We know that it is 4/7 of the left dip
therefore:
amount divided among the two friends = (4/7) x (3/4) = 3/7 of the original amount of dip.
This amount is divided among two friends,
amount that each friend gets = (3/7) / (2) = 3/14 = 0.2 of the amount of dip
tell me if this is completely wrong because i'm not good at this
14.6m
volume of a hemisphere = (2/3)πr3
Therefore r = Cube root of ( Volume * 3/2 * 1/ pi)
r = cube root ( 6466 * 3/2 * 1/ π)
r = 14.56
in the nearest tenth of a meter = 14.6 m

When you do 64/80 you get 0.8 which means that the percent decrease is .2
im ok, i can help
