the error is that they didnt add the exponets
Answer:
Average rate of change = 20.2
Rate of change at the left endpoint : f' (5) = 4t = 20
Rate of change at the right endpoint : f' (5.1) = 4*5.1 = 20.4
Step-by-step explanation:
The average rate of change of the function
F(t) = 2t^2 - 1 , [ 5,5.1 ]
solution
=
= [ 2 ( 26.01 - 25 ) / 0.1 ]
= 2.02 / 0.1 = 20.2
Rate of change at the left endpoint : f' (5) = 4t = 20
Rate of change at the right endpoint : f' (5.1) = 4*5.1 = 20.4
Answer:39
Step-by-step explanation:
90-51=39
2a. speed= distance
---------------
time
60÷69 = 52.1739 miles per hour.
so for the next one with the airplane flies 296 km in 276 min is the same formula.
296/276 = 39.9839 mph.
I couldn't see the first question clear...sorry but apply same formula.
Hoping this will help you
It’s 40 because it’s closer to 40 than 30
