The First two coefficients are positive because they are on the positive side of the y-axis. 
The Last two are on the negative side of the y-axis. B is the closest to zero as the wider the graph is, the lower the coefficient is.
 The coefficient with the greatest value would be D
 
        
             
        
        
        
Answer:
6.9 foot.
Step-by-step explanation:
Given: Length of lamp post= 12-foot.
            The angle of elevation of the sun is 60°.
∴ The length of Lamp post, which is opposite is 12-foot.
   Now, finding the length of shadow cast by foot lamp.
Length of shadow is adjacent.
∴ We know the formula for  =
= 
Next, putting the value in the formula.
⇒ 
Cross multiplying both side and using the value of Tan 60°
∴ Adjacent=  ≅ 6.9 (nearest tenth value)
 ≅ 6.9 (nearest tenth value)
6.9 is the length of shadow cast by a 12-foot lamp post.
 
        
             
        
        
        
Answer:
Initial Amount=1
Decay Factor=0.99987
Decay Rate=0.013%
Step-by-step explanation:
If P = 0.99987ᵃ
I. Initial amount 
The initial amount is when a=0
P = 0.99987⁰ = 1
The Pressure at Sea Level=1
II. Decay factor 
This is like the decay constant. From the model, P = 0.99987ᵃ, the decay constant/factor is 0.99987.
III. Decay Rate = 1-0.99987 = 0.00013
Expressed in Percentage = 0.013%
