Hello,
<span> exponential models are useful short-term, but not long-term: not reasonable

Hope this helps
        
                    
             
        
        
        
Answer:
72 km/h
Step-by-step explanation:
 We need to convert units
so: 
20 m    -----  1 km -------- 3600 s
1 s         -----  1000 m ----1 h
and solve ot
20 x 1 x 3600 s = 72000  we multiply  numerators
1s x 1000 m x 1 h = 1000  we multiply denominators
we divide de results 72000/1000 = 72
 
        
             
        
        
        
Answers:
Step-by-step explanation:
Our equation is:  With f meaning "fare" (price) and m meaning "miles".
   With f meaning "fare" (price) and m meaning "miles".
Question 7 - Juan's fare for his ride costs $6.05. We must solve for  .
.
Step 1. Substitute - <em>Substitute the fare for  in the equation.</em>
 in the equation.</em>

Step 2. Simplify/Solve - Solve for  .
.

<em>- Distribute</em>

<em>- Subtract 0.2 from 2.25</em>

<em>- Subtract -2.05 from 6.05</em>

<em>- Divide both sides by 0.2</em>

<u>And you have your answer of 20 miles.</u>
Question 8 - Same equation, different fare. 
Step 1. Substitute

Step 2. Solve

And like so, we have 
<em>The equation given is  . S =  typing speed, w = words per 5 mins, and e= errors.</em>
. S =  typing speed, w = words per 5 mins, and e= errors.</em>
Question 9 -
<em>We are given this information: S = 55, W  = 285. We are solving for e</em>.
Substitute - 

Solve -

So they would make 1 error.
Question 10 - 
<em>Information given: 300 = w, 5=e. We are solving for S</em>
Substitute - 

Solve -

Their speed is 50.
Question 11 -
<em>Information given: S = 65, e = 4. We are solving for w.</em>
Substitute -

Solve - 
 
So w = 365.
 
        
             
        
        
        
100 days because 40 divide by 4 = 10 10 x 10 =100
