Answer: -8.93
Step-by-step explanation:
Given the function:
N(X) = 90(0.86)^x+ 69
X in the interval [0, 6]
For X = 0
N(0) = 90(0.86)^0 + 69
90 + 69 = 159
For X = 6
N(6) = 90(0.86)^6 + 69
90(0.404567235136) + 69
= 105.41105116224
Therefore, average change of change in temperature ;
(temp 2 - temp 1) / ( time 2 - time) 
(105.41105116224 - 159) / (6 - 0)
= - 53.58894883776 / 6
= - 8.93149147296
= - 8.93

Answer:
they are equal to each other
Step-by-step explanation:
no because 2/3 is a simplified version of 4/6, so they are equal
 
        
                    
             
        
        
        
50 mph for 3 hours = 150 miles 
70mph for 2.5 hours = 140 + 35 = 175
175 miles - 150 miles = 25 miles
