Answer:
5/3
Step-by-step explanation:
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:
Where is the number??????
Resolving p = 1.95t² + 12.25t + 125
<span>year=2010 </span>for t=0
<span>year=2021 </span>for t<span>=(2021-2010)=11 </span>
We have that
p =
1.95*(11) ^² + 12.25*(11) + 125
p =495.70
thousands of dollars
p =495700<span> dollars </span>
<span>is the best estimate for the price of the house in year 2021</span>
3b because b^2-4= 1/b. So 2/1/b= 2b b+2b = 3b
