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.

How much does this fish weigh? How much does this fish weigh if it's tail weighs 4kg , it's head weighs as much as it's tail and
denis23 [38]
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.
