27.8 × 9.6 is equal to <span>266.88</span><span>
So, the closest would be A. 280.</span>
Answer:
- 9
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

Here [a, b ] = [ - 5, 2 ], thus
f(b) = f(2) = 2² - 6(2) + 2 = 4 - 12 + 2 = - 6
f(a) = f(- 5) = (- 5)² - 6(- 5) + 2 = 25 + 30 + 2 = 57 , thus
average rate of change =
=
= - 9
Distance = velocity * time
= 3 * 10^8 * 8.64 * 10^4
= 2.592 * 10^13 meters (answer)
2/3=14/21 and 5/7=15/21 so 14/21+15/21=29/21 or 1 and 8/21
