Step-by-step explanation:
Hello there!
Just divide 1000 by 100, because 100 cm = 1 m.
1000/100= 10 m.

Answer:
F= 4 4/6
Step-by-step explanation:
Lets break it down
3 1/6 + f - 7 5/6
3 plus what equals 7 answer 4!
1/6 pls how many more sixths equals 5/6th answer 4/6 ths
so overall you combine the two answers for whole and fraction an
Answer:
well it looks equal to 15 cm so its probably 15 cm
Give brainliest :)
Answer:
the ball reaches a height of 64 feet after 2 sec.
The ball is in the air 4 sec.
Step-by-step explanation:
The ball is following the path of a parabola. The maximum height is at the vertex of the parabola.
Let (h, k) be the vertex. h will be the time it takes to reach the maximum height, and k will be that height.
y = 
h = -b/2a = 64/(-2)(-16) = 64/32 = 2
k = -16(2)^2 + 64(2)
-16(4) + 128
- 64 + 128 = 64
V: (2, 64)
So the ball reaches a height of 64 feet after 2 sec.
Let
= 0 (0 is the height when the balls hits the ground)
-16t(t - 4) = 0
t = 0 or t = 4
The ball is in the air 4 sec.
