Answer:
There are 30 blue berries
Step-by-step explanation:
1:7
_:210
210/7
30
Let the radius be: r and height be h
volume = πr²
if the radius is halved then radius = r/2
and height is doubled, so height= 2h
volume = πr*r/4*2h = π*r²*h/2
Thus the volume will be halved.
Answer:
(4,6)
Step-by-step explanation:
The midpoint=(
=(4,6)
Your first and second derivatives which are the velocity and the acceleration respectively are correct.
The particle has reverses direction when v(t) ≤ 0 so at interval 2 < t < 5 sec.
You can substitute now t = 2 for s(2) and a(2) for first changing direction. Also t = 5 for s(5) and a(5) for second changing direction.
