Step-by-step explanation:
By Pythagoras' theorem,
12^2 = 11^2 + height^2
height = ±√12^2 - 11^2 (rej -ve value since height > 0)
height = 16.279 (5sf) = 16.3 (nearest tenth place)

Answer:
C
Step-by-step explanation:
C is not a function because 5 has two y values
2x+7=?
X=6
2(6)+7=
12+7=19
In six years, the tree will be 19ft
2x+7=44
Minus seven on both sides
2x=37
Divide two from both sides
X=18.5
Thus, it will take 18 and a half years for the tree to reach 44ft
Yea, it’s 180cm^3
V=bh
V= 20cm • 9cm
V=180cm^3
Have a good day :)
