I believe 9, is it one of your options?
Answer:
9 years
the tree doubles in height
we can make a model
1 x 2 = 2
2 x 2 = 4
4 x 2 = 8
8 x 2 = 16
16 x 2 = 32
32 x 2 = 64
64 x 2 = 128
128 x 2 = 256
256 x 2 = 512
512 x 2 = 1024
Let's say 1024 is the maximum height
half the maximum height is 1024 x 0.5 = 512 so it will take 9 years because it reached 512 on the 9th year

Answer:
Step-by-step explanation:
<u>Use this formula for interest:</u>
- I = Ptr, where I - interest, P- principal, t- time, r - interest rate
<u>Substitute values and solve for r:</u>
- 18 = 150*6*r
- r = 18/900
- r = 2/100
- r = 2 %
