Answer:
domt know which one but this may help
Step-by-step explanation:
when you take 38707 into consideration the 3 would be 30,000 the 8 would be 8,000 and the 7 would be 70
 
        
             
        
        
        
We have the following function:
 f(t) = −16t2 + 34t + 546
 By definition, the average rate of change is:
 Avr = (f (t2) - f (t1)) / (t2 - t1)
 We have then:
 For t1 = 5:
 f (5) = -16*(5)^2 + 34*(5) + 546
 f (5) = 316
 For t2 = 5:
 f (7) = -16*(7)^2 + 34*(7) + 546
 f (7) = 0
 Substituting values:
 Avr = (0 - 316) / (7 - 5)
 Avr = -158
 Answer:
 The average rate of change of f (t) from t = 5 seconds to t = 7 seconds is -158 feet per second.
        
             
        
        
        
Answer:
x + y = 41 
x - y = 13
------------------
2x = 54..............We divide 2 such that 
x = 27
Then we plug 27 into the equation such that 
27 + y = 54.................Subtract 27 to get 
y = 14
