Answer:
- A) 9 ft
- B) 13 ft
- C) 1/2 second
Step-by-step explanation:
Your notes on the problem tell you how to work it.
Part A. The height of the ball when t=0 is d(0) = 9 . . . . feet.
____
Part C. (Your notes rightly say work this first.)
... t = -b/(2a) = -16/(2(-16)) = 1/2
The ball reaches its maximum height after 1/2 second.
____
Part B. d(1/2) = 16t(-t+1) +9 = (16)(1/2)(-1/2 +1) +9 = 4 +9 = 13 . . . . feet.
The maximum height is 13 ft.
Answer:
-7/6
Step-by-step explanation:
-2/3 x 7/4 = -14/12 = -7/6
My answer was 56/27. Here is the work I did.
Answer: 26000 pounds
Step-by-step explanation:
First, we need to find out the total weight of the box
4 x 3.25 tons = 13 tons
Now, we need to convert 13 tons to pounds
To convert to pounds we need to multiply by 2000
So, 13 x 2000 pounds = 26000 pounds
