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:
c) -11 1/2
Step-by-step explanation:
basically, you work backwards using the inverse operation.
start with -7, subtract 5.25 and you get -12.25, then add .75 (3/4) and you get -11.5 or -11 1/2
Divide 120 by 4 to get 1/9 of the rope: 30. Then multiply it by 9 to get the part after 1/4 was given away: 270. Now divide it by 3 to get 90 and lastly, multiply it by 4 to get a final answer of 360 centimeters. Hope this helps!
Answer:
4
Step-by-step explanation:
If Michael paid $11.48 total and each piece of cheese costs him $3.28, then we would need to divide.
11.48 divided by 3.28 would equal 3.5
3.5 = 4

Body Weight: w=(t+0.5w)+t
Tail Weight: t=4
Head Weight: t+0.5w
w=t+0.5w+t
But t=4,
w=4+0.5w+4
w-0.5w=8
0.5w=8
Therefore: w=16.
