Answer:
(-2,21)
Step-by-step explanation:
2 days ago, Paulo's commute time was halfway between his commute times 8 and 9 days ago.
8 days ago means that x-coordinate -8 represents this day. Count 8 units to the left and find that when x = -8, y = 24 minutes.
9 days ago means that x-coordinate -9 represents this day. Count 9 units to the left and find that when x = -9, y = 18 minutes.
Find halfway commute time between points (-8,24) and (-9,18):

then coordinates that Paulo should graph are
(-2, 21)
(-2 means 2 days ago, 21 is the halfway)
18% of 4,500 is 810
4,500x0.18=810
Therefore, 18% of $4,500.00 is $810.00
(A) They emit more carbon than they take in. The fact that it is a carbon sinks, thus it does not emit more carbon.
I think it is b I think I’m right
Cosine = adjacent / hypotenuse
cosine = 5 / 13
answer is a)
