Answer:
Of those farms, 686 harvested 100 acres (0.40 km 2) or more, which accounted for over 196,000 of the total acres of trees harvested. That same year, there were only three U.S. Christmas tree farms with more than 10,000 acres (40 km 2) of cropland in production.
Explanation:
Each year, forests in North America grow significantly more wood than is harvested. In the U.S., average net annual increase in growing-stock trees on timberland is about 25 billion cubic feet.
The answer is D. an equal distance with an equal amount of force.
This is because the two cylinders have the same diameter and the liquid inside them will not compress. So when one of the pistons (both pistons are also equal size) is pressed, the same amount of liquid is moved from one to another.
Answer:
a = 132 m/s^2
Explanation:
f(t) = t^4 − 2t^3 − 6t^2 + 9t
v = f'(t) = 4t^3 - 6t^2 - 12t + 9
a = f''(t) = 12t^2 - 12t -12
Substitute t = 4 seconds into the equation for a:
a = 12(16) -12(4) -12 = 132 m/s^2
