The inequality expression for the number of years when tree will be atleast 20 feets tall is x ≥14
- Growth rate = 1.3 feets per year
The height of the tree after x years can be represented as a linear equation thus :
<u>Number of years when the tree will be 20 feets tall</u> :
- 20 = 2 + 1.3x
- 20 - 2 = 1.3x
- 1.3x = 18
- x = 13.84
<u>The tree would be atleast 20 feets tall in 14 years x this can be expressed thus </u>

Answer:
B
Step-by-step explanation:
Answer:
tan ∅ = 16/12
Step-by-step explanation:
Once again here are the trigonometric ratios
Sin = Opposite over Hypotenuse
Cos = Adjacent over Hypotenuse
Tan = Opposite over Tangent
We are asked to find tan ∅
Looking at the trigonometric ratios we see that tan = opposite over adjacent
So we find the side length opposite of the indicated angle (∅) which would be 16 then we find the angle adjacent angle ( the side that is not the hypotenuse nor the opposite ) so the adjacent of angle ∅ is 12
so tan ∅ = opposite (16) over adjacent (12)
tan ∅ = 16/12
