Answer:
The last one
Step-by-step explanation:
The function modelled by the height (x) of the tree is as follows:
y - 180 = (368 - 180)/(7 - 3) (x - 3)
y - 180 = 47(x - 3) = 47x - 141
y = 47x - 141 + 180 = 47x + 39
Therefore, after 10 years, the tree will be 47(10) + 39 = 470 + 39 = 509 cm tall
Answer:
d = 
Step-by-step explanation:
The distance formula is d=
.
6 is
, 9 is
, 3 is y
, and -2 is y
.
When you plug these into the formula, you get d =
