The answer is 1/12. Hope this helps :D
It would be 15-5=10 that is because you subtract q3-q1
9/10 is about 10/10 or 1 and 1/3 is about 0, so just add 1+0=0. Annie walked 1 mile yesterday.
Hope that helped:D
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.
