Answer: 6x+9c+4
Step-by-step explanation: (8 + 6x) + (-4 + 9c)
8+6x-4+9c
6x+9c+8-4
6x+9c+4
They get 2/3 because 2 divided by 3=2/3.
Answer:
32pi
Radius=1/2 Diameter
radius=2
Area of circle= pi*radius^2= 4pi
4pi*8=32 pi
Answer:
initial velocity = 64 m/s
Step-by-step explanation:
Differentiate H = 64t - 16t² to find an equation for velocity:
Velocity =
= 64 - 32t
Initial velocity (u) is when t = 0:
u = 64 - 32(0)
⇒ u = 64 - 0
⇒ u = 64 m/s
